(2) CHAPTER ONE INTRODUCTION L Chapter One INTRODUCTION This manual is intended to outline responsibilities for the con- tinued operation and maintenance of the Honey Creek Sewage Pump Station. To that end, it includes system and component description information, record keeping requirements, emergency operating measures, safety precautions, and relevant utilities information. The manual shouid be the primary reference for all personnel involved with the pump station. Operation and Managerial Responsibility The City of Renton owns the Municipal Sewerage System of which the pump station is a part. The City Sewer Supervisor is responsible for operation, maintenance and management of the sewerage system. The Sewer Supervisor and assigned staff are responsible for: 1. Knowing and understanding proper operational procedures. 2. Keeping accurate records. 3. Properly managing operating funds. 4. Keeping supervisors and other necessary personnel informed. 5. Staying informed of current operation and maintenance (0 & M) practices. To ensure efficient and economical system operation, it is impor- tant that each staff person has a clear definition of his/her respon- sibilities. Coordination and communication between staff personnel is imperative to proper operation of the facility. (3) 0 1 Description of Pump Station. Honey Creek Pump Station is located just east of the sharp curved junction of NE 27th Street and 120th Place S.E. It is inter,+ad to intercept sewage by gravity flow from the southeast, where it is collected in a 72" diameter concrete storage pipe. Sewage thus inter- cepted will be pumped to the existing gravity sewer west of Edmonds Avenue in NE 27th Street. The pump station is specially equipped with variable orifice knife gates to permit flow modulation. This equipment will , at the City's discretion, permit full time diversion of the Honey Creek Park Pump Station No. 1 inflow. Additionally, during peak wet season inflow infiltration, the City may also divert overflow from SunsEl PuwP -tatian. 5incc the pumping cost per unit of sewage is higher at Honev Creek . imp Station, it is desirable to maintain the Sunset Pump Station in continuous operation. 1) The new Honey Creek pump • ation consists of two vertical , non-clog Clow-Yeomans pumps, each with a 3 phase, 40 horsepower motor capable of 4' 7� passing 500 gpni at 126' of total dynamic head. The pump station is housed in a reinforced Plastic laminated enclosure. Primary energy ource is electric, with a trailer-mounted portable electric generator ,I"NQ/ r emergency standby capability. The emereency generator is garaged at ire- t e Highlands Pump Station at NE 12th Street 4nd Olympia Avenue NE. r I 9 d►-�#C Sewage collected in the 72" diameter concrete storage pipe to the 90 a southeast en' ars the pump station wet well via an 18" ductile iron pipe. Si^ r The wet well is a 96" diameter, 15' deep concrete structure, directly !!n� underneath the above-ground pump enclosure. Level sensors activate one of the pumps, which alternates lead on operation when sewage reaches the set level . The pumped sewage flows through 2200 Lf of 8" AWWA C900 PVC force main pipe in NE 27th, until it drops into the gravity line west of Edmonds Avenue NE. A series of alarms are built into the system, as well as flow modulation and monitoring devices. A more detailed des- cription can be found in Chapter Three, and in the Appendix. �- lni rSw�ar Ste ���nf*� ry...,.evJ ;t2� Cn�/ 5,,,.Se► CAI 51-sh'' � �ye:,ke sw"�U N�.of M,.eh C.0 S4,d,x a.� iu N6 !ice ?'C'e 9ryir" VRIVLs J Abbreviations In a manual of this nature, it becomes necessary to use a certain number of technical terms and also to abbreviate these and other more common terms to avoid lengthy repetition in the text. For the con- venience of the reader, the meaning of the principal terms and their abbreviations are listed: Quantity and Rate Terms gal Gallons Standard U.S. gallon measure. C.f. Cubic Foot (feet) A volume measure. One cubic foot of volume contains 7.5 gallons. gpd Gallons Per Day A rate of flow in total gallons over a 24-hour period. gph Gallons Per Hour Self-explanatory. gpin Gallons Per Minute Self-explanatory.

It is the only way to identify performance trends, track 0 & M costs to pre- pare meaningful budgets, and permit staff persons to be in control of pump station performance rather than always reccting to unanticipated operations. Operation records show a record of flow and/or pumping time, and include such information as el:ctrical power consumption, weather conditions, labor, time and costs of maintenance or repair and notes on performance of mechanical equipment. Process Operations/Daily Operating Log Activities, general conditions and other items that are documented in writing for future reference. The Sewer Utility Foreman shall compile and maintain a daily log and monthly summaries of activities at the facilities. Information recorded in the log should include: 0 Routine operational duties and time utilized by personnel o Unusual conditions (operational and maintenance) o Accidents to personnel o Complaints (odor, noise, leaks, etc. ) 0 Flowmeter totalizer readings (periodic monitoring of remote flow measuring manholes) o Weather conditions o Power Consumption (monthly or as available) o Running Timf deter Readings o Emergency Conditions (7) The above listed information should be recorded on a prepared form, which can be similar to those used at other pump stations in the sewage system. Example forms are shown in the Appendix. The daily log should be kep: at the pump station, as well as any other designated shop location. Monthly and Annual Reports The daily operating log should be summarized monthly on a form similar to the one in the Appendix. At year end (fiscal or calendar) the Utility Supervisor or his designated staff person should submit an annual summary of operating and management data. It is most efficient to use forms provided by the State which are available from the Depart- ment of Ecology. A copy of the monthly and annual reports should be kept at the City Shops, and the originals submitted to the Director of Public Works. Maintenance Records Individual maintenance records for each item of equipment should be kept in a notebook at the pump station. Such records can reveal the weaknesses of various pieces of equipment and which parts should be kept in stock. These cards should record dates of regular lubrication, inspections, cleaning and replacement of worn parts, and other important data. The date for the next regular servicing of equipment should be plainly visible on the card. In addition to the cards, a separate lubrication record should be kept, which lists each piece of equipment and the instructions for lubricating, including the recommended type and frequency of lubrication. This record should enable the operator to set up a lubrication schedule for the equipment. The maintenance cards can be used to set Up d preventive mainte- nance program with lists of operations to be done on certain dates. The items can be entered in advance on a memo calendar pad. For any program to be successful , it must be accepted by tht maintenance personnel. Sometimes this will make or break the entire program. The cards should be simple, and instructions regarding the routine work should be clear. (8) Operating Costs Operating costs are not usually maintained by the Supervisor but should be kept by the City's Finance Director. Records should be kept of all expenses incurred at the pump station. The major categories of operating costs are labor, utilities, and supplies. Labor costs includes operation, administration and maintenance; utility costs include electricity, telephone, and potable water; supply costs include cleaning materials, maintenance supplies and other expendable items. In addition, keep records of all overhead expenses, including insurance. Records should include information on unit costs, total costs, and quan- tities. If a complete record of operating costs is maintained, budget- ing and cost control will be much easier and this information will help justify and document future sewer rate increases. Inventory Records The Sewer Supervisor should establish and meintain a card file inventory of all replacement and maintenance parts including: o Part Name o Model Number o Cost a Local Distributor o Date Ordered 0 Date Used o Delivery Schedule, if unusual This information will prove very valuable in parts replacement, irdering and budgeting. ,`7/ p�a�a„ n.�r`r.11... �• '�� K(�Mvul$ f-73Q�:�IQOO C04 4-.+1 1 I ' (9) CHAPTER THREE OPERATION AND MAINTENANCE OF PUMP STATION Chapter Three OPERATION AND MAINTENANCE OF PUMP STATION General In subsequent paragraphs the major pieces of equipment at Honey Creek pumping station are described and the required maintenance detailed. A guide checklist is provided to help organize an operation and maintenance schedule. Pumps The two Clow-Yeomans Model 4312, Series 6260 vertical non-clog pumps are standard models designed for heavy duty municipal sewage use. They are vertical , flexible - coupled pumps with high efficiency impellers designed for minimum maintenance requirements. The pumps have 4" discharge orifices and are capable of passing a 3" solid sphere wjlW= out clogging. The following design characteristics apply: / Full Load Operating Speed: 175U rpm I �� y5 ? Motor Horsepower: 40 hp Shut-off Head: 157 ft.a Design Capacity Rating: 400 gpm @ 122' TDH 500 gpm @ 126' TDH Motor Characteristics: 3 Phase 60 Hertz 125 amp / 480 Volt Service The wet well mounted pumps will alternate lead on position to pre- vent excessive wear of either pump. Should one pump fail to operate, the other will be activated. The sequential operation of the pumps is discussed in greater detail in the Pump Level Controls Section. The pumps have been provided with carbon-ceramic mechanical seals, which are r to be water lubricated (from protected potable supply). Either pump can be removed for inspection or service by means of a trolley and chain hoist, with crane rail and supports, which is provided in the enclosure. (10) The local supplier of the Clow Yeomans pump; is H.O. Fowler Com- pany; 13440 SE 30th Street; P.O. Box 160; Bellevue, WA 98009; telephone (206) 746-8400. The vertical pumps are enclosed in a prefabricated reinforced fiberglass pump house which sits directly above a 96" diameter wet well Each pump has a 4 ductile iron suction intake line 15'4" long, which extends from 8" above the floor of the wet well . From the 4" pump is- charge, the sewage line is increased to 6" , then passes through a wafer check valve designed to reduce operational fouling. This is followed in turn by a 6" knife gate which permits a defined "V" orifice flow con- trol , The two discharge links meet in a wye with an increaser adaptor connecting to the 8" ductile iron force main. At any time, either pump may be taken out of service for maintenance operation by isolating the line at the knife gate (i.e. closing it) and adjusting the alternator to utilize a one pump mode. <— �� P" "1 ""s r� PAP Vacuum Priming Pumps Mounted on the walls of the pump station enclosure on either side of the Clow Sewage Pumps are two Piston Vacuum Priming Pumps. Each is a Gast Model 1 VAF, and operates on 100 volts. Routine Maintenance and Lubrication The Clow sewage pumps require no maintenance other than periodic inspection, lubrication and occasional cleaning. The intent of inspection is to prevent breakdown, thus obtaining optimum service life. Please refer to the Appendix containing the Clow Pump literature pro- vided by the manufacturer for specific guidance. The following trouble shooting guide will aid if :,pecific problems arise. (11) Pump Troubleshooting Cause-No Liquid Delivered Cure 1. Lack of prime Fill pump and suction pipe completely with liquid. 2. Loss of prime Check for leaks in suction pipe "oints and fittings; vent casing to remove accumulated air. 3. Suction lift too high If no obstruction at inlet, check for pipe friction losses. However, static lift may be too great. Measure with mercury column or vacuum gage while pump is operating. If static lift is too high liquid to be pumped must be raised or pump lowered. 4. Discharge head too high Check whether the valves are wide open. 5. Speed too low Check whether motor is directly across the line and receiving full voltage, or frequency may be too low; motor may have an open phase. 6.

Wet Well and Sump Cleaning Sewage solids settling in backwater eddies in wet wells or sumps v will start decomposing in a matter of hours or days depending on the temperature of the sewage. Higher temperatures kwithin ordinary limits) accelerate decomposition. Sewage solids left stranded by receding water levels will also decompose rapidly. Wet wells and sumps are designed with steeply sloping side fillets to minimize the solids collection problem. However, no perfectly self-cleaning structures have yet been .visPd. Pumping a wet well down as far as possible under manual control at variable intervals and hosing down with a good jet of water is usually sufficient to eliminate solid build-up and the resulting decomposition odors. The timing of the intervals will depend on sewage temperature, frequency of automatic pumping and can best be determined from observation and experience. <" Another source of foul odors can be slime growth on wet well and sump walls at or near the usual high water line. These growths on wet well walls can generally be kept under control by scrubbing with a stiff r bristle brush followed by hosing. (15) Another source of odors and of mechanical trouble is grease accumu- lation on pump station wet wells. Remove grease in the same way that slime growths are controlled. Unusual quantities of grease entering the system should be traced to their source and eliminated. This problem usually requires some good detective work on the part of the maintenance personnel . Gasoline stations, garages, machir^ shops, restaurants, and bakeries are prime suspects of grease. Pump Level Controls Tile wet well is equipped with individual mercury float switches which control "pump on" and "pump off" operation, as well as other alarm and control functions. The Honey Creek 1•3vel controls are Model 476E as manufactured by Enpo-Cornell Pump Company. They are strap mounted by a nreasonabl plastic strap. K� ' Five adjustable level floats are provided from the highest level , in descending order, they indicate: 1) High Lev.-.I Alarm �0 2) Lead Pump On (alternator changes lead puinp after each pumping cycle) 3) Second Pump On S�� 4) Pump Off h 5) Low Level Alarr --� Floats number 1 and 5 indicate abnormal emergency conditions, which are indicated at the site by alarm and at the City Shop via telemetry equipment. It is important that conditions are investigated and j remedied at once when alarms are triggered. >bCI.in 1' l Al ;evt( <<J- ,re„k- � a(o— Runr,' U Time Meters 1>24010- — *I .41,nAs sd+"%e /Cvala -fry 4;� Pe"" Vbj .. rxpld✓- M I-/ f /o a,V r"Y -f.5— Running Time Meters on the pump control panels show the tota .�wrll o 46J'q number of hours of operation each pump has accumulated. Readings shout (o;xvdr be recorded at every inspection. In this way it will be obvious how q k,.q 9 many hours the pump operates each day. Whenever a lead pump starts 4u,,y (16) 1ia 6-et�, t.�e.�t�y r 4Yo,s "/e w (under automatic control ) during an inspection, record the time it takis it to pump to the 'stop' setting. These pumping times can be eapec!.ed to vary at different times of day and different days of the week as sewa^e flow rates vary. This information w4ll be useful in several ways. If the discharge f-om one pump is noticeably less than from the other it requires prompt ,,ttention. If things have been running normally (with each pump operat- ing regularly) , but suddenly one day the Running Time Meter shows considerable operation of only one pump, it is likely due to a clogged pump or piping. The Running Time Meter keeps tack of the hours o, operation accumulated by each pump so that the lead and lag status of the pump in each station can be alternated to equalize wear. Finally, the most important function of the Running Time Meters for the service life of the equipment, is to record the hours of operation for lubrication scheduling in accordance with the manufacturer's recom- mendations. 54acdr it o(r Pf�s 44 Ammeters �4(�_ Ammeters in the motor control panel show the amount of power a motor is drawing. The readings should be noted at each inspection. Power usage can be expected to vary at different times of the day and different days of the weeks as sewage flow rates vary, but soon a trend for each motor will develop. A small plate is attached to each ammeter and indicates the normal operating range. If abnormal readings are noticed, make a record of the readings to establish a trend in the abnormal power usage. Record the date and time of the readings. This record may help to determine the probable cause of the unusual power usage. (17) If a pump ammeter indicates a higher than normal reading, the pump motor is orawing too much power. Some reasons for the higher than usual pump power usage are as follows: 1. Clogged impeller 2. Pumping against lower than normal pressure 3. Defective motor or pump shaft bearings 4. Packing gland too tight A few reasons for lower than normal power usage are as follows: 1. Damaged impeller 2. Pumping against higher than normal pressure 3. Clogged suction or discharge piping 4. Suction or discharge valves partially or, fully closed 5. Pump Cavitation Ammeters are important indicators of how equipment is functioning and can forewarn of a potential problem. Ammeters should be checked at least once a day. 5 w ' Ja�^a Sha l� Electrical Equipment �� YU ye/� f . be Electrical Switchgear. In most cases operators should not attempt to repair electrical switchgear other than to replace fuses or individual circuit breakers as required. There is always an element of danger present in making repairs, and persons not qualified are advised to seek the help of specialists. Make certain that any electrical equipment which is to be either worked on or inspected is isolated from operating electrical circuits. When specific electrically operated units are undergoing repair, it is always advisable to lock the individual starter or breaker unit in the "off" position and to place a tag on the starter unit indicating that the starter or breaker is not to be tripped. Eames. Electric lights provided for illumination or for indicating various control functions should always be maintained in operating condition. Test and inspect all lamps regularly to ensure that they are (18) in an operating condition and that a supply of spare lamps is on hand. Illuminated control panels are useless if indicator lights do not function properly since their real value is to indicate which equipment is in operation at any given time. Installing long-time or industri- ally-rated lamps may reduce lamp replacement problems and costa. Miscellaneous Equipment Piping. Piping requires periodic painting and occasional cleaning. It may also be necessary occasionally to tighten flanges or replace gaskets in order ti stop leakage, When changing piping layouts, give particular attention to adequate and proper pipe supports. Be sure to note any modifications on as-built drawings. Knife Gate Valves. The valves do not require lubrication. Maintenance involves replacing worn packing and tightening followers to prevent leakage around the valve stems. It is advisable to operate all valves periodically by opening and closing them to order to ensure that the valve will not stick in either the open or closed position. Wafer Check Valves for Sewage Pumps. The station piping, fittings, and especially valves can become clogged and are potential trouble spots. The cause of trouble in check valves is almost always the nuts and cotter pins used to hold the discs to their pivot arm assemblies. The castellation's sharp corners on the nuts can catch rags and the cotter pins are as efficient as fishhooks in holding the material . Rags caught in a valve can prevent tight seating of the disc. A valve which tails to seat properly will let part or all of the contents of the discharge piping drain back to the wet well , lowering the efficiency of the statiun. Rags caught in a properly adjusted check valve will soften or eliminate the normal click on closing. (19) If an improperly seated valve is suspected: 1. Look in the wet well . If the water level is low, a backflow current from the pump can often be detected in the question- able piping. 2. By listening directly to the valve in question; sometimes a leakage flow can be heard. 3. Press hard on the lever arm; sometimes a tell-tale resiliency can be felt. 4. Run the pump for a moment or two until the lever arms shows "full open," and then stop it, watching the closing action of the lever and listening for the closing "click. " You may have to stop the other pump if it is running, to be sure of what you hear. pn***' °PC', .��-- Sewer Maintenance General . A good sewer maintenance program involves continuously in- spection and routine cleaning of the complete system as often as time, manpower and economy allows. Inspections will provide early detection of potential stoppages and/or deterioration so that major problems can be prevented. r An invaluable aid to a maintenance program is a complete set of current maps of the whole system. These maps should be "AS BUILT," showing grades, pipe sizes, types of materials, side sewers, stubs and location of the manholes. The frequency of inspection of a system will vary with slope, size, age and record of past troubles. Most sewer maintenance programs give first attention to sewers which have poor performance records usually resulting from flat grades, buildup of grease or root penetration, (20) ground settlement or shifting, etc. Aside from these problem areas, the frequency of inspection for various parts of the system should be as follows: Monti Inspections. Inspect all sewers where the design indicates flowing full velocities of two feet per second or less, and all sewers showing very low daily maximum flows, such as at the upstream ends of laterals and extensions. Also, inspect sewers where the desig indi- cates full flowing velocities of more than 6 feet per second. Inspect all sewers flowing with full velocities of less than 3 feet per second which are subject to buildup of grease such as in commercial areas where restaurants, garages, service stations, etc. are —non. uarterly Inspections. Inspect all sewers where the design indicates full velocities of two to three feet per second and which seldom flow more than one-quarter full , and all sewers with full velocities of more than three feet per second which are subject to buildup of grease. Annual Inspections. Inspect all sewers which flow at least half full during porn ,1 daily peak flows which have full velocities of between two and eight feet per second and which are not subject to abnormal buildup of grease. In general , judgment and experience are necessary for the develop- ment of an adequate schedule of preveitive maintenance which is not prohibitively expensive. A maintenance program should achieve the following objectives: 1. Inspection of sewers and appurtenances, including testing of manholes and structures for hazardous gases. 2. Cleaning. 3. Repairing. �. 4. Checking for sources of infiltration and surface water enter- ing the sanitary sewer system. (21) M - M 5. Checking sources of unusual amounts of industrial wastes. Formulated for these objectives, a maintenance program can be truly "preventive," correcting potential stoppages and problems before they become serious, and avoiding outright system or component failures. Stoppages. The most common obstructions in ,ewers are roots, accumu- lations of grease, grit and miscellaneous debris. Normally when a stoppage occurs, manholes are inspected until the first downstream manhole with abnormally low flow is found. This isolates the obstruction between the low flow or dry manhole and the next upstream manhole. First, rt is wise to check the first full manhole's outlet for stoppage using a long hooked rod or simi ' ir device. If this fails, the generally accepted procedure is to rod upstream from the ory manhole. This affords the advantage of a clear manhole to work from and also uses the flushing effect of the wastewater flow in clean- ing the stoppage. One should keep in mind the possibility that when rodding upstream an auger may branch into a wye connection causing damage to a side sewer. If rout penetration is the cause of a stoppage, it is easier to rod from the upstream manhole, because roots generally grow downstream. The roots may be more easily cut from the upstream side and the obstruction can usually be washed downstream to the next manhole where it can be removed. Stoppages may also be caused by a break in the line. If this is the case, generally a large amount of mud, sand or gravel washed into the system will reveal the problem. Sometimes a telltale sinkhole or depression may form in the vicinity of a break, or excessive infiltra- tion is evident in the downstream manhole. When d break has occurred, and is bracketed between manholes by inspection, procedures other than normal maintenance will have to be employed. All too often sand and gravel is dropped into manholes that are located in road shoulders when graders catch the top frar. s. Routine inspection is essential in discovering such problems. (22) Cleaning of Sewers. Various methods are available for sewer cleaning, depending on what equipment the City has at its disposal at a given time. there are four common methods: rodding, bucket machines, "jets" , and inflatable sewer balls. Complete stoppages caused by sand, grease, roots or other debris may be openeo and sometimes removed by rodding equipment. Various rodding heads can be used to break or remove the obstruction. The sewer can then be cleaned by hydraulic flushing equipment or a bucket machine. Hydraulically propelled sewer cleaning tools usually called "jets" rely on water pressure to provide cleaning and propulsion. The head of the hydraulic cleaning unit gavels along the run of pipe blasting away the debris in the pipe and flusning it out with the water used. Pump Station Checklist Following is an operation and maintenance checklist for a pump station. Although it is not a complete list of everything the operator should be observing, it will serve as a guide for setting up a schedule. The schedule will help the operator organize work in a step-by-step fashion, and it will alsu help new personnel who are not familiar with the facility. _ `7 1 �d�es c^:!w_ 4 o 4-) d— �IS'^ Jo uca. 4 YCfl� t�G IOW �s, — , 1L_ ra 1 q7�' � v � t J C b.W a�� Metiv� ��lw✓ Q' � P✓dv- 1� 1ptlk.; '7�W- ' Gulp �19 <W -loolsjw'°.d '� . , �r'ld..,� .,��,�.�h:. — � �?�w�:— stH,/s � v61e ``- {JYc1 M�• (23) Table 1 MAINTENANCE SCHEDULE Operational and -e uenc Preventive As Maintenance Oaily Meekly Monthly 3 Mos. 6 Mos.

Visual Inspection X (24) CHAPTER FOUR SAFETY Chapter Four SAFETY Wet Wells and Sewer Manholes The principal hazards associated with sewer manholes or other en- closed areas are oxygen deficiency, explosions and toxic gases. Oxygen deficiency occurs whenever air (normally about 21`0 oxygen by volume) is displaced by some other gas, which may or may not be toxic. Oxygen de- ficiency (less than 13% oxygen) can be detected with an oxygen level detector. Any confined space where there is an accumulation of sewage solids is a suspected hazard. Symptoms of a lack of oxygen are yawning and a drowsy sensation. As a safeguard, two individuals should always be pre- sent when any work is to be accomplished within a pump station wet well or sewer manhole, and only one should be in the confined space; the other should be tending a lifeline on the deck above with portable oxygen breathing equipment. Oxygen deficiency indicators and combust- ible gas indicators are described fully in the Water Pollution Control Federation's Manual of Practice No. 1, Safety in Wastewater Works. If an area is suspected to be deficient in oxygen, ventilation should be provided with an air blower. The motor should be explosion- proof or located at least six feet upwind of the manhole. This will avoid ignition of explosive gas mixtures if any are present. Explosive conditions may exist in confined locations if sewage gas, or any flammable vapor is present in sufficient quantities. No smoking should be allowed near any confined area that contains sewage or settled sewage solids. If electrical equipment is needed in such an area, pro- vide ventilation long enough to displace any gases present with air before operating the electrical equipment. �f 7 �ho,N 16-1 L, J5 �a�,j lei Pip eJ!— 4 o�..� c>p•+ �' G�JScxwe I a.r &or it ? (25) Electrical Hazards A pumping facility incorporates sophisticated electrical equipment. Properly trained and qualified personnel are the only ones who should be permitted to work on this equipment. All electrically operated tools should contain a third-wire ground or be of double insulated construction. Periodically check to ensure that no electrical leakage exists in the tool or cord. Smoking, open flames, and spark-producing or flame igniting devices are not permitted near batteries. Place rubber mats in front of all electrical control panels. When working on any piece of electrical equipment, make sure that both the switch at the equipment and the switch at the control panel are open and tagged. _yam 'r-e tio✓c_ f—hfu + 1„��,7 bVas A;s 4 �/.� pord '4 �� $r J 1 Mechanical Equipment Hazards Much of the equipment requiring maintenance is electrically driven but mechanical in its operation: pumps are one example. This dictates a combination of safety practices involving both aspects of the equipment. A�� Exposed shafts are some of the most hazardous items on mechanical d I equipment. nclose all shafts in sheet metal or wire guards. Tie back therwise restrain long hair and avoid loose fitting clothing. is The maintenance, repair or removal of mechanical equipment requires close coordination with operating personnel to ensure a minimum of shut- down time. The need for quick restoration of service may lead to decreased compliance with all appropriate safety measures. Plan and schedule all maintenance functions to be performed properly, if practi- cable, and undertaken with all necessary tools, materials and manpower available at the site. (26) Each person should know their job and understand the hazards in- volved to himself or herself, co-workers, and the system of which the equipment is a part.

J(ools (28) CHAPTER SIX MAINTENANCE OF 1INTERCEPTOR .n n J i ' Chapter Six GENERAL The 12-inch sewer interceptor down Honey Creek was designed to ultimately accommodate the full service area flow from the Sunset Pump Station No. 2, plus the Honey Creek Pump Station No. 1. Until such time as the interceptor is continued down May Creek, the interceptor and Honey Creek Pump Station will receive highly variable flow. -he interim flows through the interceptor consist of; 8-inch gravity system ir, Union Street; the Honey Creek Park Pump Station No. 1 (if diverted by facility); overflows from Sunset Pump Station No. 2; and individual sewer services along the interceptor route. Overflows to the inter- ceptor from the Sunset Pump Station collectors are controlled by opening or closing a mud valve in a sewer manhole located in the Union Avenue and Sunset Boulevard intersection. Sewer Interceptor The sewer is 12-inch Sclairpipe, polythylene DR 32.5, and is approximately 5,000 feet long from the Honey Creek Pump Station to Phase II Manhole No. 1 in Union Street. The pipe supnlier is H.D. Fowler. The -i�,,-thirds of the sewer interceptor runs adjacent tc Honey Creek underneath a gravel access road. The access road bridges the creek in three locations. The upper one-third of the sewer was installed directly underneath the Honey Creek creek bed. The pipe is protected by crushed bedding and heavy fractured scour rock. Ductile iron fittings were used fur all side sewer connections and cleanouts. Cleanouts were installed at 400 feet spacing (8 sections of pipe) and oriented so that cleaning equipment can be used in tht upstream direction. Pigging is becoming a more widely recognized method of cleaning water and sewer iines and can be utilized for the long sewer inter- ceptcr. The pig is a bullet-shaped foam cylinder which is pushed or (29) pulled through a pipe scraping and cleaning the inner pipe wall. A local supplier of pigs is D.R. Shannon Company, Inc. of Seattle, and a copy of the manufacturer's specifications :s included in the Appendix. The YBS-B bullet type Polly Pig is a recommended type for the Honey Creek sewer interceptor. However, there are many types of pion for the different applications and the manufacturer's representative should be consulted. Pigging the interceptor should be done at least annually. The manufacturer's recommenaed method of pigging should be followed and must be subject to steps specific to this application. These steps will be somewhat based on a "trial and error" process by the City's Maintenance Department. Special maintenance considerations should be given to the first 400-foot section of the interceptor between the 6-foot diameter wet well and Phase II clean-out No. i. Sewage backing up in the 6-foot diameter wet well will cause sewage flow in .ne interceptor to temporarily stop. This may result in increased bt old up of material to the pipe's inner wail and will accordingly require more frequent cleaning. Locatiuri rof the oolythylene sewer is generally toward the middle of the road. Alignment under bridges is offset some. Alignment of pipe in the creek above the road is close to the center of the creek. Galvan- ized wire was strung with the pipe to use as a ra locator, The ? cleanouts for in-road location are centered directly over the pipe. J Access Road and Creek In addition to maintaining tri, ewer interceptor, considerations must also be given to the access drive and the structural integrity of the creek bed where the sewer is placed under the creek. Weekly ano/or following each major storm, an inspection walk of the creek roadway and upper creek is suggested. Specific notations relative to location of any erosion bank slumps should be recorded and be referenced on the as- built drawings. Road embankments and areas adjacent to the bridge (30) structures are more likely subject to severe erosion. Should major erosion take place, the Sewer Supervisor should inform the City Engineer at once. A good quality rock, 8-inch to 15-inch (12-inch average) , may be used to re-stabilize severely eroded areas along the creek. 2 :6"M4 owe.

(2) CHAPTER ONE INTRODUCTION Chapter One INTRODUCTION This manual is intended to outline responsibilities for the con- tinued operation and maintenance of the Honey Creek Sewage Pump Station. To that end, it includes system and component description information, record keeping requirements, emergency operating measures, safety precautions, and relevant ut lities information. The manual should be the primary reference for all personnel involved with the pump station. Operation and Managerial Responsibility The City of Renton owns the Municipal Sewerage System of which the pump station is a part. The City Sewer Supervisor is responsible for operation, maintenance and managemer,'. of the sewerage system. The Sewer Supervisor and assigned staff are responsible for: 1. Knowing and understanding proper operational procedures. 2. Keeping accurate records. 3. Properly managing operating funds. 4. Keepi ; ervisors and other necessary personnel informed. 5. Staying i, formed of current operation and maintenance (0 & M) practic,s. To ensure efficient and economical system operation, it is impor- tant that each staff person has a clear definition of his/her respon- sibilities. Coordination and communication between staff personnel is imperative to proper operation of the facility. (3) ��.:.�/U�.

Honey Creek Pump Station is located just east of the sharp curved junction of NE 27th Street and 120th Place S.E. It is intended to intercept sewage by gravity flow from the southeast, where it is collected in a 72" diameter concrete storage pipe. Sewage thus inter- cepted will be pumped to the Pxisting gravity sewer west of Edmonds Avenue in NE 27th Street. The pump station is specially equipped W th v. able orifice knife gates to permit flow modulation. This equipment will , at the City's discretion, permit full time diversion of the Honey Creek Park Pump Station No. 1 inflow. Additionally, during peak wet season inflow infiltration, the City may also divert overflow from the Sunset Pump Station. Since the pumping cost ner unit of sewage is higher at Honey Creek Pump Station, it is desirable to maintain the Sunset Pump Station in continuous gperatigpn. �iOCCl�d/Ca D/' i. `ail f- /', S/A fle�J� /hf l/•C/7''t�oLAtE /<;/TJ'/��en paq'" UnierJ Ave / y4k/3 iq C47f�r�Pi SiK. The new Honey Creek pump station consists of two vertical , non-clog Clow-Yeomans pumps, each with a 3 phase, 40 horsepower motor capable of passing 500 gpm at 126' of total dynamic head. The pump station is housed in a reinforced plastic laminated enclosure. Primary energy source is electric, with a trailer-mounted portable electric generator for emergency standby capability. The emergency generator is garaged at the Highlands Pump Station at NE 12th Street and Olympia Avenue NE. u Y� Sewage collected in the 72" diameter concrete storage pipe to the southeast enters the pump station wet well via an 18" ductile iron pipe. The wet well is a 96" diameter, 15' deep concrete structure, directly underneath the above-ground pump enclosure. Level sensors activate one of the pumps, wh4,h alternates lead on operation when sewage reaches the set level . The pumped sewage flows through 2200 LF of 8" AWWA C900 PVC force main pipe in NE 27th, until it drops into the grav line west of Edmonds Avenue NE. A series of alarms are built into the system, as well as flow modulation and monitoring devices.

For the con- venience of the reader, the meaning of the principal terms and their abbreviations are listed: Quantity and Rate Terms g: Gallons Standard U.S. gallon measure. C.f. Cubic Foot (feet) A volume measure. One cubic foot of volume contains 7.5 gallons. gpd Gallons Per Day A rate of flow in total gallons over a 24-hour period. gph Gallons Per Hour Self-explanatory. gpm Gallons Per Minute Self-explanatory.

It is the only way to identify performance trends, track 0 & M costs to pre- pare meaningful budgets, and permit staff persons to be in control of pump stat!on performance rather than always reacting to unanticipated operations. Operation records show a record of flow and/or pumping time, and include such information as electrical power consumption, w^ather conditions, labor, time and costs of maintenance or repair and notes on performance of mechanical equipment. Process Operations/Gaily Operating Log Activities, general conditions and other items that are 6 .•-.,,,iented in writing for future re erence. The Sewer Utility Foreman shall compile and maintain a daily log and monthly summaries of activities at the facilities. Information recorded in the log should include: o Routine operational duties and time utilized by personnel 0 Unusual (,)nditions (operational and maintenance) o Accidents to personnel o Complaints (odor, noise, leaks, etc. ) 0 Flowmeter totalizer readings (periodic monitoring of remote flow measuring manholes) o Weather conditions o Power Consumption (monthly or as available) o Running Time Meter Readings o emergency Conditions (7) The above listed information should be recorded on a prepared form, which can be similar to those used at other pump stations in the sewage system. Example forms are shown 'it the Appenoix. The daily log should b, kept at the hump station, well as any other designated shop location. Monthly and Annual Reports The daily operating log should be summarized monthly on a form similar to the one in the Appendix. At year end (fiscal or calendar) the Utility Supervisor or his designated staff person should submit an annual summary of operating and management data. It is most efficient to use forms provided by the Scate which are available from the Depart- ment of Ecology. A copy of the nwrfthly and annual reports shout,' be kept at the City Shops, and the originels submitted to the Direc�,,t of Public Works. Maintenance Records Individual maintenance records for each item of equipment should be kept in a notebook at the pump station. Such records can reveal the weaknesses of various pieces of equipment and which parts should be kept in stock. These cards should record dates of regular lubrication, inspect`ons, cleaning and replacement of worn parts, and other important data. The date for the next regular servicing of equipment should be plainly visible on the card. In addition to the cards, a separate lubrication record should be kept, which lists each piece of equipment and the instructions for lubricating, including the recommended type and frequency of lubrication. This record should enable the operator to set up a lubrication schedule for the equipment. The maintenance cards can be used to set up a preventive mainte- nance program with lists of opecations to be done on certain dates. The items can be entered in advance on a memo calendar pad. For any prog am to be successful , it must be accepted by the maintenance personnel. Sometimes this will make or break the ent, a program. The cards should be simple, and instructions regarding the routine work should be clear. (8) 3 W k Operating Costs y Z Operating costs are not usually maintained by the Supervisor but h should be kept by the City's Finance Director. Records should be kept V The major categories o of all expenses incurred at the pump station. 0 operating costs are labor, utilities, and supplies. Labor costs includes operation, administration and maintenance; utility costs d u include electricity, telephone, and potable water; supply costs include k" "i cleaning materials, maintenance supplies and other expendable items. In 1� addition, keep records of all overhead expenses, including insurance. " . Records should include information on unit costs, total costs, and guan- o titles. If a complete record of operating costs is maintained, budget- ing and cost control will be much easie, and this information will help justify and document future sewer rate increases. A Inventory Records The Sewer Supervisor should establish and maintain a card file inventory of all replacement and maintenance parts including: 4 � Q Q d o Part Name V � 0 � o Model Number o Cost Q ` o Local Distributor i� i �, � o Date Ordered o Date Used 4 o Delivery Schedule, if unusual o V This information will prove eery valuable in parts replacement, ordering and budgeting. lu u lJi.r Ik, , p1 r ,rl 6a 2rota A�tgr/Jt!/ '► g8S l900day orRll�h/ • �e.uil �1d / ll�Il �: r r �nd�(1 ��L D �GN f J / 4G p { 7 ' R u /G� i .� ��j�X, f 674� lb y �64 Jel- lox,, nrr,�f } • 1 • e CHAPTER I THREE + TI OPERATION AND MAINTENANCE OF PUMP STA, ON 7. - w Chapter Three OPERATION AND MAINTENANCE OF PUMP STATION General In subsequent paragraphs the major pieces of equipment at Honey Creek pumping station are described and the required maintenance detailed. A guide checklist is provided to help organize an operation and maintenance schedule, PUMPS The two Clow-Yeomans Model 4312, Series 6260 vertical non-clog pumps are standard models designed for heavy duty municipal sewage use. They are vertical , flexible - coupled pumps with high efficiency impellers designed for minimum maintenance requirements. The pumps have 4" discharge orifices and are capable of passing a 3" solid sphere with- out clogging. The following design characteristics apply: Full Load Operating Speed: 1750 rpm Motor Horsepower: 40 hp Shut-off Head: 157 ft.♦ De ign Capacity Rating: 400 gpm @ 122' TDH 500 gpm @ 126' TDH Motor Characteristics: 3 Phase 60 Hertz 125 amp / 480 Volt Service Cl,�-r.��} ,cju4.i•.G so .c,�t-l�c.e'��' .✓-,, �� atc;I�tet��f.... The wet well mounted pumps will alternate lead on position to pre- vent excessive wear of either pump. Should one pump fail to operate, the other will be activated. The sequential operation of the PUMPS is P a«iCr.,w_ discussed in greato. detai? in the Pump Level Controls Section. The pumps have beer provided with carbon-ceramic mechanical seals, which are to be water lubricated (from protected potable supply). Either pump can be removed for inspection or service by means of a trolley and chain hoist, with crane rail and supports, which is provided in the enclosure. (10) (he local supplier of the Clow Yeomans pumps is H.D. Fowler Com- pany; 13440 SE 30th Street; P.G. Box 160; Bellevue, WA 98009; telephone (206) 746-8400. The vertical pumps are enclosed in a prefabricated reinforced fiberglass pump house which sits directly above a 96" diameter wet well . Each pump has a 4" ductile iron suction intake line 15'-4" long, which extends from 8 above the floor of the wet well . From the 4" pump dis- charge, the sewage line is increased to 6" , then passes through a wafer check valve designed to reduce operational fouling. This is followed in turn by a 6" knife gate which permits a defined "V" orifice flow con- trol . The two discharge links meet in a wye with an increaser adaptor connecting to the B" ductile iron force main. At any time, either pump may be taken out of service for maintenance operation by isolating the line at the knife gate (i.e. closing it) and adjusting the alternator to utilize a one pump mode. , Vacuum Priming Pumps Mounted on the walls of the pump station enclosure on either side of the Clow Sewage Pumps are two Piston Vacuum Priming ?umps. Each is a Gast Model 1 VAF, and operates on 100 volts. Routine Maintenance and Lubrication The Clow sewage pumps require no maintenance other than periodic inspection, lubrication and occasional cleaning. The intent of inspection is to prevent breakdown, thus obtaining optimum service life. Please refer to the Appendix containing the Clow Pump literature pro- vided by the manufacturer for specific guidance. The following trouble shouting guide will aid if specific problems arise.

Wet Well and Sump Cleaning Sewage solids settling in backwater eddies in wet wells or sumps will start decomposing in a matter of hours or days depending on the temperature of the sewage. Higher temperatures (within ordinary limits) accelerate decomposition. Sewage solids left stranded by receding water levels will also decompose rapidly. Wet wells and sumps are designed with steeply sloping side fillets to minimize the solids collection problem. However, no perfectly self-cleaning structures have yet been devised. Pumping a wet well down as far as possible under manual control at variable intervals and hosing down with a good jet of water is usually sufficient to eliminate solid build-up and the resulting decomposition odors. The timing of the intervals will depend on sewage temperature, frequency of automatic pumping and can best be determined from observation and experience. Another source of foul odors can be slime growth on wet well and sump walls at or near the usual high water line. These growths on wet well walls can generally be kept under control by scrubhing with a stiff bristle brush followed by hosing. (15) Another source of odors and of mechanical trouble is grease accumu- lation on pump station wet wells. Remove grease in the same way that slime growths are controlled. Unusual quantities of grease entering the system should be traced to their source and eliminated. This problem usually requires some good detective work on the part of the maintenance personnel . Gasoline stations, garages, machine shops, restauragt pd bakeries are prime suspects �f' yreaseNr�red�.' �aN s�Le Pump Level Controls The wet well is equipped with individual mercury float switches which control "pump on" and "pump off" operation, as well as other alarm and control functions. The Honey Creek level controls are Model 476E as `-,�;opfactured by Enpu-Cornell Pump Company. Five adjustable level floats ate-provided from the highest level , in descending order, they indicate: 1 ) High Level Alar7i, 2) Lead Pimp On (alternator changes lead pump after each pumping cycle) 3) Second Pump On 4) Pump Off 5) Low Level Alarm Floats number 1 and 5 indicate aenormar ae, yuncy conditions, which are indicated at the site by alarm and at the City Shop vie telemetry equipment. It is i;„portdnt that conditions are investigated and remedied at once when alarms are triggered. Runniny Time Meters Running Time Meters on the pump control panels show the total number of hours of operation each pump has accumulated. Readings should be recorded at every inspection. In this way it will be obvious how many hours the pump operates each day. Whenever a lead pump starts (16) i .a �c�.ems �-+te����y,.c�'�.rc�� •*-�-s�� Coif���/2.

Ammeters Ammeters in the motor control panel show the amount of power a motor is drawing. The readings should be noted at each inspection. Power usage can be expected to vary at different times of the day and different days of the weeks as sewage flow rates vary, but soon a trend for each motor will develop. A small plate is attached to each ammeter and indicates the normal operating range. If abnormal readings are noticed, make a i .cord of the readings to establish a trend in the abnormal power usage. Record the date and time of the readings. This record may help to determine the probable cause of the unusual power usage.

If a pump ammeter indicates a higher than normal reading, the pump motor is drawing too much power. Some reasons for the higher than usual pump power usage are as follows: 1. Clogged impeller 2. Pumping against lower than normal pressure 3. Defective motor or pump shaft bearings 4. Packing gland too tight A few reasons for lower than normal power usage are as follows: 1. Damaged impeller 2. Pumping against higher than normal pressure 3. Clogged suction or discharge piping 4. Suction or discharge valves partially or fully losed 5. Pump Cavitation Ammeters are important indicators of how equipment i<_ functioning and can forewarn of a potential problem. Ammeters should be checked at least once a day.

Make certain that any electrical equipment which is to be either worked on or inspected is isolated from operating electrical circuits. When specific electrically operated units are undergoing repair, it is always advisable to lock the individual starter or breaker unit in the "off" position and to place a tag on the starter, unit indicating that the starter or breaker is not to be tripped.

It may also be necessary occasionally to tighten flanges or replace gaskets in order to stop leakage. When changing piping layouts, give particular attention to adequate and proper pipe supports. Be sure to note any modifications on as-built drawings. ..A Knife Gate Valves. The valves do not require lubrication. Maintenance r involves replacing worn packing and tightening followers to prevent leakage around the valve stems. It is advisable to operate all valves periodically by opening and closing them in order to ensure that the valve will not .;tick in either the open or closed position. 1�� �f (!f17 eck�for Sewage Pumps. The station piping, fittings, and pecially valves can become clogged and are potential trouble spots. The cause of trouble in check valves is almost always the nuts and cotter pins used to hold the discs to their pivot arm assemblies. The castellation's sharp corners on the nuts can catch rags and the cotter pins are as efficient as fishhooks in holding the material . Rags caught in a valve can prevent tight seating of the disc. A valve wnich fails to seat properly will let part or all of the contents of the discharge piping drain back to the wet well , lowering the efficiency of the station. Rags caught in a properly adjusted check valve will soften or eliminate the normal click on closing. ,Ae' �...� .0, w If an improperly seated valve is suspected: 1. Look in the wet well . If the water level is low, a backflow current from the pump can often be detected in the question- able piping. 2. By listening directly to the valve in question; sometimes a leakage flow can be heard. 3. Press hard on the lever arm; sometimes a tell-tale resiliency can be felt. 4. Rur the pump for a moment or two until th- lever arms shows "full open," and then stop it, watching the closing action of the lever and listening for the closing "click." You may have to stop the other pump if it is running, to be sure of what r rj you hear. Sewer Maintenance General . A good sewer maintenance program involves continuously in- spection and routine cleaning of the complete system as often as time, manpower and economy allows. Inspection: will provide early detection of potential stoppages and/or deterioration so that major problems c,,a�n,,//�� t , prevented. An invaluable aid to a maintenance program is a compute set of current maps of the whole system. These maps should be "* .1 showing grades, pipe sizes, types of materials, side sewers, stubs and location of the manholes. The frequency of inspection of a system will vary with slope, size, age and record of past troubles. Most sewer maintenance programs give first attention to sewers which have poor performance records usually resulting from flat grades, buildup of grease or root penetration, (20) eve." 71 r �r ��.�-�a•a i.�-l`o' �lcc, -�-�.��sE'f%a. Ti .mac-,�c.�at 0- M I ground settlement or shifting, etc. Aside from these problem areas, the frequency of inspection for various parts of the system should be as follows: Monthly Inspections. Inspect all sewers where the design indicates flowing full velocities of two feet per second or less, and all sewers showing very low daily maximum flows, such as at the upstream ends of laterals and extensions. Also, inspect sewers where the design indi- cates full flowing velocities of more than 6 feet per second. Inspect all sewers Cowing with full velocities of less than 3 feet per second which are subject to buildup of grease such as in commercial areas where restaurants, garages, service stations, etc. are common. Quarterly Inspections. Inspect all sewers where the design indicates full velocities of two to three feet per second and which seldom flow more than one-quarter full , and all sewers with full velocities of more than three feet per second which are subject to buildup of grease. Annual Inspections. Inspect all sewers which flow at least half full during normal daily peak flows which have full velocities of between two and eight feet per second and which are not subject to abnormal buildup of erea.a. In general , judgment and experience are necessary for the develop- ment of an adequate schedule of preventive maintenance which is not prohibitively expensive. A maintenance program should achieve the following objectives: 1. Inspection of sewers and appurtenances, including testing of manholes and structures for hazardous gases. 2. Cleaning. 3. Repairing. 4. Checking for sources of infiltration and surface water enter- ing the sanitary sewer system. (21) 5. Checking sources of unusual amounts of industrial wastes. Formulated for these uGjectives, a maintenance program can be truly "preventive," correcting potential stoppages and problems before they become serious, and avoiding outright system or component failures. Stoppages. The most common obstructions in sewers are roots, accumu- lations of grease, grit and miscellaneous debris. Normally when a stoppage occurs, manholes are inspected until the first downstream manhole with abnormally low flow is found. This isolates the obstruction between the low flow or dry manhole and the next upstream manhole. First, it is wise to check the first full manhole's outlet for stoppage using a long hooked rod or similar device. If this fails, the generally accepted procedure is to rod upstream from the dry ,manhole. This affords the advantage of a clear manhole to work from and also uses the flushing effect of the wastewater flow in clean- ing the stoppage. One shuuld keep in mind the possibility that when rodding upstream an auger may branch into a wye connection causing damage to a side sewer. If root penetration is the cause of a stoppage, it is easier to rod from the upstream manhole, because roots generally grow downstream. The roots may be more easily cut from the upstream side and the obstruction can usually be washed downstream to the next manhole where it can be removed. Stoppages may also be caused by a break in the line. if this is the case, generally a large amount of mud, sand or gravel washed into the system will reveal the problem. Sometimes a teiltale sinkhole or depression may form in the vicinity of d break, or excessive infiltra- tion is evident in the downstream manhole. When a break has occurred, and is bracketed between manholes by inspection, procedures other than normal maintenance will have to be employed. All too often sand and gravel is dropped into manholes that are located in road shoulders when graders catch the top frames. Routine inspection is essential in discovering such problems. (22) Cleaning of Sewers. Various methods are available for sewer cleaning, depending on what equipment the City has at its disposal at a given time. There are four common methods: rodding, bucket machines, "jets", and inflatable sewer balls. Complete stoppages caused by sand, grease, roots or other debris may be opened and sometimes removed by rodding equipment. Various rodding heads can be used to break or remove the obstruction. The sewer can then be cleaned by hydraulic flushing equipment or a bucket machine. Hydraulically propelled sewer cleaning tools usually called "jets" rely on water pressure to provide cleaning and propulsion. The head of the hydraulic cleaning unit travels along the run of pipe blasting away the debris in the pipe and flushing it out with the water used. Pump Station Checklist Following is an operation and maintenance checklist for a pump station. Although it is not a complete list of everything the operator should be observing, it will serve as a guide for setting up a sc. ole. The schedule will help the operator organize work in a step-by-step fashion, and it will also help new personnel who are not familiar with the facility.

Oxygen deficiency occurs whenever air (normally about 21% oxygen by volume) is displaced by some other gas, which may or may not be toxic. Oxygen de- ficiency (less than 13% oxygen) can be detected with an oxygen level detector. Any confined space where there is an accumu' kja of sewage solids is a suspected hazard. Symptoms of a lack of oxygen are yawning and a drowsy sensation. As a safeguard, two individuals should always be pre- sent when any work is to be accomplished within a pump station wet well or sewer manhole, and only one should be in the confined space; the other should be tending a lifeline on the deck above with portable oxygen breathing equipment. Oxygen deficiency indicators and combust- ible gas indicators are described fully in the Water Pollution Control Federation's Manual of Practice No. 1, Safety in Wastewater Works. if an area is suspected to be deficient in oxygen, ventilation should be provided with an air blower. The motor should be explosion- proof or located at least six feet upwind of the manhole. This will avoid ignition of explosive gas mixtures if any are present. Explosive conditions may exist in confined locations if sewage gas, or any flammable vapor is present in sufficient quantities. No smoking should be allowed near any confined area that contains sewage or settled sewage solids. If electrical equipment is needed in such an area, pro- vide ventilation long enough tc displace any gases present with air `before operating the electrical equipment.

This dictates a ombination of safety practices involving both aspects of the equipment. \ Exposed shafts are some of the most hazardous items on mechanical ipment. Enclose all shafts in sheet metal or wire guards. Tie back �► otherwise restrain long hair and avoid loose fit". i g. The maintenance, rep it ur removal of mechanical equipment requires lose coordination with operating personnel to ensure a minimum of shut- down time. The need for quick restoration of service may ' -ad to decreased compliance with all appropriate safety measures. Plan and schedule all maintenance functions to be performed properly, if practi- cable, and undertaken with all necessary tools, materials and manpower available at the site. (26) Y Each person should know their job and understand the hazards in- volved to himself or herself, cc-workers, and the system of which the equipment is a part.

Chapter Six GENERAL The 12-inch sewer interceptor down Honey Creek was designed to ultimately accommodate the full service area flow from the Sunset Pump Station No. 2, plus the Honey Creek Pump Station No. 1. Until such time as the interceptor is continued down May Creek, the interceptor and Honey Creek Pump Station will receive highly variable flow. The interim flows through the interceptor consist of: 8-inch gravity system in Union Street; the Honey Creek Park Pump Station No. 1 (if diverted by facility); overflows from Sunset Pump Station No. 2; and individual sewer services along the interceptor route. Overflows to the inter- ceptor from the Sunset Pump Station collectors are controlled by opening or closing a mud valve in a sewer manhole located in the Union Avenue and Sunset Boulevard intersection. Sewer Interceptor The sewer is 12-inch Sclairpipe, polythylene DR 32.5, and is approximately 5,000 feet long from the Honey Creek Pump Station to Phase II Manhole No. 1 in Union Street. The pipe supplier is H.D. Fowler. The lower two-thirds of the sewer interceptor runs adjacent to Honey Creek underneath a gravel access road. The access road bridges the .reek in three locations. The upper one-third of the sewer was installed directly underneath the Honey Creek creek bed. The pipe is protected by crushed bedding and heavy fractured scour rock. Ductile iron fittings were used for all side sewer connections and cleanouts. Cleanouts were installed at 400 feet spacing (8 sections of pipe) and oriented so that cleaning equipment can be used in the upstream direction. �r ��irtDfic P�� e 01 Pigging is Waw4A more widely recognized method of cleaning water and sewer lines and can be utilized for the long sewer inter- ceptor. The pig is a bullet-shaped foam cylinder which is pushed or (29) pulled through d pipe scraping and cleaning the inner pipe wall. A local supplier of pigs is D.R. Shannon Company, Inc. of Seattle, and a copy of the manufacturer's specifications is included in the Appendix. The VBS-B bullet type Polly Pig is a recommended type for the Honey Creek sewer interceptor. However, there are many types of pigs for the different applications and the manufacturer's representative should be consulted. Pigging the interceptor should be done at least annually. The manufacturer's . ecoim ended method of pigging should be followed and must be subject to steps specific to this application. s Qopi URwr!. Special maintenance considerations should be given to the first 400-foot section of the interceptor between the 6-foot diameter wet well and Phase II clean-out No. 1. Sewage backing up in the 6-foot diameter wet well will cause sewage flow in the interceptor to temporarily stop. This may result in increased build up of material to the pipe's inner J wall and will accordingly require more frequent cleaning. ;1� • Location of the polythylene sewer is generally toward the middle of the road. Alignment under bridges is offset some. Alignment of pipe in the creek above the road is close to the center of the creek. Galvan- ized wire was strung with the pipe to use as a t'„ ,, locator. The cleanouts for in-road location are centered directly over the pipe. Access Road and Creek In addition to maintaining the sewer interceptor, considerations must also be given to the access drive and the structural integrity of the creek bed where the sewer is placed under the creek. Weekly and/or following each major storm, an inspection walk of the creek roadway and upper creek is suggested. Specific notations relative to location of any erosion bank slumps should be recorded and be referenced on the as- built drawings. Road embankments and areas adjacent to the bridge (30) .��,,f°�wa'y w Q ��1� � , z�GC_.cev.ZG �_' _ -�.ate ,di _ � � LLss. �4� .G=�la�.v..sl� A � � ��y�� .tilt �� .

Scott's leak checking progress at the Hone) Creek pump station, I did some additional flow checks in the gravity sewer west of Kenrl. ,iale. MalcL 'm Thomson a.1d Don Jacoby of the Maintenance Department were at the site to view the instrument and to assis' . Readings were made in Manhole #F040, the designated metering manhole. Manhole #F04O is on North 28th Street , midway between Park Avenve and Mead. ThL flow was small in the 30-40 gpm range. Apparently I,either the ,Azalea Lane nor the private condominium pump station near Kennydale School were on during this time. W, made measurements at roughly 3-minute intervals as tabulated below: FLOW RATE DATE TIME LOCATION WEIR TYPE IN GPM 12/3/86 12:47 PM Manholf No. F040 Circular 50 12:47 PM Circular j 40 1:13 PM V Notch 40 1: 16 PM 36 1:19 PM 36 1:22 PM 29 1:25 PM 28 1:34 PM 38 1:43 PM�� // 43 REPLVTO ❑5[ATTLE ❑WENATCHEE E- I - Don Jacoby had some good thoughts on measuring. Don was a tlow measurement specialist with Gelco and thought the Flow Poke unit would be a good investment for the City. To determine the effective pipeline residual capacity, additional flow measurements are needed when the Azalea and Kennydale private pump stations are on concurrently. Flow measurements made on Tuesday, November 25, 1986, right after the heavy storm, are tabulated below: FLOW RATE DATE TIME LOCATION WEIR TYPE IN GPM 11/25/86 9:56 AM Manhole No. 039 Circular 517 9:57 AM 552 9:58 .AM 537 9:59 AM 532 10:00 AM 521 10:01 AM 525 10:03 AM 520 10:06 AM 515 10:09 AM 525 10: 12 AM 487 10: 15 AM 515 10:19 AM 513 A Tittle bit of flow checking with each of the pumps on would provide a good index of additional available capacity. This would entail coordinating measurements and pure 'off with walkie-talkie radio communication. Your Public Works staff is welcome to use the Flow Poke equipment we have or we can assist too. I will further discuss this with you later. Sincerely, HAMMOND, COLLIER & WADE - LIVINGSTONE ASSOCIATES, INC. Frederick G. Kern, P.E. FGK/rt W20-52 0 HAMMOND.COLLIER&WADE—LIVINGSTONE ASSOCIATES.

W. Scott Company 9840 Carr Road Renton, Washington 98055 Re: Honey Creek Pump Station Dear Tom: The oump control system is eery sensitive to the val:uum eductor unit. After the vacuum system is energized and completes the eduction routine, the pump starter is electrically interlocked. When the pump comes on, the vacuum system float is affected and sometimes a shut-off signal is sent to the pump. The vacuum system then periodically allows the pump starter to trip in and out. The interrupted starter operation is not good. The situation is not resolved to the City's satisfaction nor to ours. The City has a good deal of experience with vacuum systems for smaller units. The specific problems for the Honey Creek unit seem to be more difricult to isolate. Part of the roblem is a leak in the pump suction area. Therc are a number of areas of leakage suspect, "2" pipe saddle, pump to suction pipe riser, seals, tapped ports or perhaps the vacuum system plumbing. Another part of the problem is in the design of the vacuum system. Specifications do not state what frequency of adjustment or cleanout of the vacuum lines and float system is reasonable. However, cased on the City's experience with similar stations, the adjustments at this station are too frequent and not com.id. od a reasonable standard of practice. Specificall, , the vacuum hose to the Small impeller por', plugs too easily. This problem was not apparent during pump start-up testing because potable water was uLd to fill the wet well rather than raw sewage. We are working on improving thN vacuum system by retrofitting some of the plumbiny of the vacuum piping and chamber directly with H. D. Fowler. How- ; -ver, there are still air leaks based on vacuum pump operational period. We quest that you assist the City in remaking-replacing any joints and fittings at have leas. VEPLVTO C'St.-ILE GWENATCNEE Mr. Tom Kivley December 1, 1986 Page Two Another discovery we made was that the pump seal water supply take off is ahead o - rather than behind the backflow prevention b.f.p. device. The seal water supply should be replumbed to the downstream side of the b.f.p. Tae City needs to make the corrections quickly now ti•at the heavy wet weather protection for which the pump was designed is here. If the vacuum system contin- ues to intermittently fail , the pump stations could be flooded during a heavy storm. We believe if the problem is not corrected soon the pump motor and starter equipment will be damaged. The operational problems are not a result of improper lack of maintenance by the City staff. PROPOSAL 1. The first job is to track down the leak in the system. A proper system should hold the vacuum prime for several days. The City has done some press�ir< testing of the suction side of the pump but has found no leaks. We expect the contractor to assist in finding leaks, disassembling pieces, regasketing, and eliminating the leaks. The work needs to be scheduled when the pumps can be taken of line a short time during a non-rainfall period. We request that you call Gary Morrison directly to arrange this work. 2. The fresh water pump seal discharge needs to be replumb�d downstream of she b.f.p, and this work also requires pump shut down during non-rainfall Period. 3. Concurrent with the two activities (noted above), we plan to schedule the vacuum system retrofit for the week of December 1, 1986, We will recommend to the City payment of a)iy costs that we fairly determine to be beyond the scope of the contractor's responsibility. There is an urgent need to correct the problems, and we will count on ,our support to get the ,job done properly. Thank you for your consideration.

Bergstrom, P.E. Engineering Supervisor City of Renton Department of Public Works City Hall , 200 Mill Avenue Renton, Washington 98055 Re: Honey Creek HCW-L #2850P3 Dear Bob: As discussed by telephone, we are working with Gary Morrison in trying to elimi- nate vacuum alld other operating problems at the Honey Creek Station. In regard to the knife 9aLe, some leakage should be anticipated. (Refer to computations sent to Gary). We will measure the leakage to determine if the units are defective. The knife gate flow-back leakage does not seem to be a problem, and I believe we can satisfactorily alleviate this problem with a hose tap to bleed off pressure when it is necessary to service the check valve, In regard to vacuum system difficulties, I 've contacted both Fred Stevens with H.D. Fowler and Tom Kivley with R.W. Scott advising that leaks in the vacuum plumbing were suspected. I also asked Fred Stevens to finish up details for .n improved Vacuum eductor piping that he had discussed with Gary Morrison. When. George Hammond and I dropped by to check the leakage with Gary, he showed me the check valves that had been taken out. The check valve arm has a number of sharp edges and hang-up ze,Ies where tampon strings, rags or other debris can hang up and hold the check va:ve open. We discussed means of weld or epoxy filling the arm check plate cavities. These hang-up problems are not an equipment warranty issue. RCRVTO ❑LEATTLE ❑WENATCHEE Mr. Robert Bergstrom November 24, 1986 Page Two Cary also mentioned that he had located the apparent trouble . pot in the vacuum system. The problem he discovered was that a bandaid and rag had been sucked up into the small impeller case evacuator line, making a tight plug, The vacuum eductor simultaneously pulls air from a 2-inch connection at the suction pipe and a 1/2-inch connection at the impeller port. I advised H.D. Fowler's Eric Merklinghause of the plugging problem. Eric will di—uss possible improvements t.) the small orifice at the impeller with the factory. . ;e Clow factory typically only provides advice through the distributor; thus, we've not gone directly to the factory for suggestions. Use of a see-through impeller suction line (tygon tube) would allow the operator to quickly check for apparent clogging. Installing a see-through line is recom- mended. In sumrrary, the problems encountered appear- to be operational rather than warranty related. We will pursue with Gary the best means of improving the features to reduce fouling and cycling problems.

Fowler that they have received castings that need to be machined for motor bracket replacements. I talked with Mike of H.D. Fowler's Pump Department because Fred Stevens was out. I told Mike that the situation was becoming serious and liquidated damages could be imposed. I 'd earlier talked with R.W. Scott's Lyle regarding getting some action on finishing the detail . Although we've been promised before, it appears castings will be delivered by Friday and H.D. Fowler plans to have their pump service contractor make new installations the week of April 14th. I have written to King on paving repair and overlay finish up. Sincerely, Frederick G. Kern, P.E. W14-89 RE0.Y TO ❑9dTTlF. QWENATCHEE HAMMOND.COLLIER&WADE- LIVINGSTONE ASSOCIATES. INC.

As you recall , we kept track of this but held onto the billing. The reason for extra Phases 1 and 2 services resulted from longer construction necessitated by delays in obtaining power easements and hillside slip relocation of the pump station. The delays required our monitoring one project at a time rather th=n concurrently, thus additional costs were incurred. Sincerely, --�54e 4C-6-6 ,- Frederick G. Kern, P.E.
