Chapter One INTRODt:CTiON This manual is intended to outline responsibilities for the con- timied operation and maintenance of the Honey Creei, Sewage Pump Station. To that end, it includes system and component description information, record keeping reduiremerts, emergency operating measures, safety precau'.ions, and relevant utilities information. The manual should oe the primary reference for all personnel involve9 with the Pumn 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 infurmed. 5. Staying informed of current operation and maintenance (V 6 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 cvmmunication between staff personnel is imperative to proper operation of the facility. • (3) • Description of Pump Station. Honey Creek Pump Station iS located just east of the sharp curved junction o: 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 existing gravity sewer west of Edmonds Avenue in NE 27th Street. The pump station is specially equipped with variable orifice knife gases to permit flow modulation. This equipment will , at the City's discretion, ;e r t full time diversion of the Honey Creek Park Pump Stat--r Na I ,f low. Additionally, during pea: wet Season infiuw infilt•aticn, the C ty may also divert overflow from the Sunset Pump Station. Since the pumping cost per unit of sewage is higher at Honey Creek Pump Station, it is desirable to maintain the Sunset Pump Station in continuous operation. O 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 c,:,, gpm at 126' of total dynamic head. The rump station is r'1 housed in a reinfurced plastic laminated enclosure. Primary energy source is electric, with a trailer-mounted portable electric generator r"Q for emergency standby capability. The emergency generator IS garaged at A� y� the Highlands Pump Station at NE 12th street and Olympia Avenue NE. S 1��>PjfxLf,� Sewage collected in the 72" diameter concrete storage pipe to the 64. 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 3ctwate one (t' of Coe pumps, which alternates lead on operation when sewage reaches the Set level. The pumped sewdye flows through 2200 LF of 8" AGMA C900 PVC force nwin pipe in NE 27th, until it drops into the gravity iine west of Edmonds Avenue NE. A series of alarms are built into the system, as well as flow moC.u?ation and monitoring devices. A more detailed des- criptior can be found in Chapter Three, and in the Appendix.4�6 / Sf 4e �.—A LaCI ,a.. tit. 0K57 (4) • Atbreviations 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. qpd Gallons Per Day A rate of flow in total gallons over a 24-nour period. • gph Gallons Per Hour Self-explanatory. Win Gallons Per Minute Self-explanatory. A common term used to rate the capacity of pumps and other facilities. fps Feet Per Second Velocity of a fluid. hp Horsepower Unit of power. Cfs Cubic Feet Per Second A rate of flow equal to approxi- mately 450 gpm. mqd Millions of Gallons Per Day Both a rate ut use and a measure of total use. A common tern in hydraulic analy- sis due to large quantities normally used. A flow rate of 1 mgd equals approximately 690 qpm. • (5) . gpcd Gallons Per Capita Per Day A term designating the aver- age amount of water used by each individual serve by the system during a 24-hour period. Pressure Terms psi Pounds Per Square Inch A meas!rce of the fluid pressure exerted at a partuular point. Usually it refers to the amount by which the pressure exceeds the atmospheric pressure at mean sea le,el (MSE).

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 reacting to unanticipated operations. Operation records show a record of flow and/or pumping time, and include such inforawtior. , electrical power consumption, weather conditions, labor, time and .,sts of maintenance or repair and notes on performance of mechanical equipment. process Operations/Daily Operating log • Activities, general cunditions and other items that are documented in writing for future reterence. The Sewer Utility Foreman shall compile and maintain a daily log and monthly sunnwries of activities at the facilities. Information recorded in the log should include: o Routine operational duties and time utilized by personnel o Unusual conditions (operational and maintenance) o Accidents to personnel o Complaints (odor, noise, leaks, etc.) o 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 U 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 kept 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- me,rt 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 lndi,iuual maintenance records for each item of equipmment should be kept in a notebook at the pump station. Such records can rtveal 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 lubricatim;, 1nci1d1n4 the recommended type and frequency of lubrication. This record shoulC enable the operator to set up a lubrication schedule for the equipment. The maintenance cards can be used tc set up a 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 the 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 Superv+ .or 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, ..fidget- ing and cost control will be much easier and this informatio- will help justify and document future sewer rate increases. Inventory Records • The Sewer Supervisor should establish and maintain a card file inventory of all replacement and maintenance parts includinc: o aart Name o Mudel Number o Cost o Local Distributor o Date Ordered o Date Used o Delivery Schedule, if unus,jal This informatimi w+; i prove very vakjable in parts replacement, ordaring and budgetinq. (g) CHAPTER THREE OPERAliON AND F ANTFNANCE OF PUMP STATION • • Chapter Three OPERATION AND MAINTENANS 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. Punk 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 nz intenance 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 1,1-. ivyf y5a�` Motor Horsepower: 40 hp Shut-off Head: 157 ft.s 6 Design Capacity Rating: 400 gpm @ 1<^2' 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 • 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 pumps is N.D. 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 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 tu,n 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 torte main. At any time, either pump may be taken out of service for maintenancI operation by isolating the line at the knife gate (i.e. closing it) and adjusting the alternator to utilize a one pump mode. er— 10se (W h�, 1••"s : "� r� e� • Vacuum Priming Pumps Mounted on the walls of the Pump station enclosure on either side of the flew Sewage Pumps are two Piston Vacuum Priming Pumps, Inchs a Gast Modei 1 VAF, and operates or: 100 volts. Routine Maintenance and Lubrication The Clow sewage pumps require or maintenance other then 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 ma ufacturer for specific guidance. The following trouble shooting guide will aid if specific problems arise.

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 observati,n and experience. Another source of fuul odurs can be slime growth on wet well and j sump walls at or near the usual high water line. these growths on wet well walls can generally be kept under control by scrubbiny with a stiff is Gristle brush followed by hosing. (15) . Another source of odors and of mechanical trouble is grease accumu- lation or, pump station wet wells. Remove grease in :he 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, restaurants, and bakeries are prime suspects of grease. Pump Level Control; 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 mangf#cturel by Enpo-Cornell Pump Company. They are strap mounted by a reasonably. plastic strap. Five adjustable level floats are provided from the highest level, • in descending order, they indicate: 1) High Level Alanr 2) Lead Pump On (alternator changes lead pump after each pumping cycle) , .j•(;,A,•.

Readings shoulO fo .,r,iji,. be recorded at every inspection. In this way it will be obvious howkv.(q. many hours the pump operates each day. Whenever a lead pump Starts•.'..„1 (16) t 46 ' (under automat! . control) during an inspection, record the time it takes it to pump to the 'stop' setting. These pumping times can be expec ed to vary at different times of day anu different days of the week as ,ewage flow rates vary. This information will be useful in several ways. If the discharge from one pump is noticeably less than from the other it requires prompt attention. If things have been running normally (with each pump ope,at- ing regularly), bu: 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 track of the hours of 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. ,,,,�,.,, Ammeters Ammeters in the Motu, 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 aitferent 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 ut the readings to establish a treno 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. 10 (17) • 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 closed 5. Pump Cavitation • Ammeters a:e important indicators of how equipment is functioning and can forewarn of a potential problem. Arvieters should be Checked at least once a day. k'Y y Electrical Equipment � dy. 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 repa i, , and persons not qualified are advised to seek the help of speck' 9age certain that any electrical equipaerit which is to be r— ,. ..:c on or inspected is isolated from operating electrical circuity. when specific electrical].) operated units are undergoing repair, it is aiaays advisabir 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. • Lamps. 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 rondition 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 costs. Miscellaneous Equipment Pipinq, Piping requires periodic pairting and occasional cleaning. 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. 8e 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 in cyder 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 valets can becoc.- clogged and ore 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 ari, assemblies. The castellation's shdrp corners on the nuts can catch rags and the cotter pins are as efficient as fishhooks in holding the material. Rags caught in a cdlve car, prevent tight ,eating of the disc. A valve which i„1 to seat properly will let Part or al of the cunte^ts of the disctdrge piping drain back to the wet well, lowering the efii,iency of the station. Rags caught in u properly adjusted check valvc will soften or elimindte the normal click or closing. (1g) • If an improperly seated valve is suspected: 1. Look in the wet well. If the water level is low, a backf low 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 en the lever arm; sometimes a tell-tale resiliency car. be felt. a. Run the pump for a moment or two until the lever arms shows "full open," and then ,top it, watching the closing action of the lever an-' 'istening for the closing "click." Yoe may have II to stop the other pump if it is running, to be sure of what �Y you hear. Se.k• P.e{.w alp-1 , , �'-- Sewer Maintenance Generdi. A good sewer ;;wifitenance program involves continuously in- spectiun and routine cleaning (it the complete systeiu as often is time, manpower and economy allows. Inspections will provide early detection of potential stoppages avid/or deterioration so that major problems can be prevented. An invaluable aid to a maintenance program is a complete set of current naps of the whole system. These naps should be "AS BUILT," showing grades, pipe sires, types of twterials, 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 fromi fiat grades, buildup of grease or root penetration, (20) ti • 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 I,•.pections. Inspect all sewers where the design indicates flowing full velocities of two feet per second or less, and all sewers showing vary 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 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 station_, efz. are common, Quarterly Inspectio,is. 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 5vCcnd and which are not subject to abnormal buildup of grease. In general, iudgment and experience are necessary for the dcvelop- nient of an odequate schedule of preventive naintenance which is not prohibitively expensive. A maintenance program snould athiete the fol iuwin5 objectives: I. Inspection of sewers and appurtenances, including testing of man.h„les and structures for hazardous gases. 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 objectives, a maintenance program can be truly "preventive," correcting potential stoppages and problems before they become sorious, and evoiding outright system or component failures. Stoppages, the most common otstructions 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 abnoraally 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 should keep is 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 downstredr: 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 d break, ur excessive infiltrd- tion is evident in the downstream manhole. When a break ids occurred, and is bracketed between manholes by inspection, procedures other than ncnnal 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) eCleaning of Sewers. Various methods are available for sewer cleaning, depending on what equipment the City has at Its disposal at a given tine. There are four common methods: rodding, bucket machines, "jets", and inflatable sewer balls. Com;lete 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 propellea sewer cleaning tools usually called "jets" rely on water pressure to provide cleaning and propulsion.

Oxygen deficiency occurs whenever air (normally about 21i, oxygen by volume) is displaced by some other gas, which may or may not be toxic. Oxygen ae- ficiency !less than 13% oxygen) can be detected with an oxygen level detector. Ary 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 breathiny equipment. Oxygen deficiency indicators and cvmbust- ible ga•, indirdtorS 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 nanhole. This will avoid ignitior of explosive gas mixtures if any are present. Explosive amditioos may east In confined locations it 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. It electrical equipment is needed in such an area, pro- vide v,ntilation lung enough to du place any gases present with air, before operating the electrical equipment. ,d _ ,.. )cr at Y,rp weF ia'' II p:r �Gr•!� (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. ,_ .- - �. ran<. s 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. Exposed shafts are some of the most hazardous items on mechanical y ra' 1 equipment, . Enclose all shafts in shec metal or wire guards. tie back "'_-15fherwise restrain long hair and avoid loose fitting clothing. The maintenance, repair or remgvdl of ILWChdniCdl 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, ano undertaken with all necessary tools, materials and manpower • available at the site. (26) . Each person should know their j b and understand the hazards in- volved to himself or herself, co-workers, and the systen, if which the equipment is a part. • • (27) CHAPTER FIVE U7ILITIES • • • Chapter Five t UTILITIES Power Electricity is provided to the pumping stations by Puget Sound Power 6 Light.

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 (it 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 muc valve in a sewer manhole located in the Union Avenue and Sunset Boulevard intersection. SSewer interceptor The sewer is '. -iuch Sciairpipe, polythylene ON 32.5, and is appr0xinmtely 5,006 ter`. long from the Honey Creek Pump Station to Phase 11 Manhole No. 1 in Urion street, The pipe supplier is H.O, Fowler. The lower two-thiros of the sewer interceptor runs adjacent to 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 Croce creek bed. The pipe is prutected by Lrushed bedding and heavy fractured scuur ruck. Ductile iron fittings were used for all side sewer connections and cleanouts. Cleanduts were installed at 400 fret spacing {6 sections of pipe) and oriented so that cleaning equipment san be used in the upstream directioe. . Pigging is becoming a more widel, recognized method of clearong water and sewer lines and can be ttflited for the long sewer inter- ceptor. The pig is a bullet-shaped foam cylinder which is pushed or (a; 2 • 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 YBS-B bullet type Polly Pig is a recommended ty�ie 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 recommended 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 11 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 wall and will accordingly require mure frequent cleaning. Location of the polythylene sewer is generally toward the middle of the road. Alignment under bridges is offset scru�. 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 .� l.. cleanouts for in-road location are centered directly over-the Access Rudd 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 an4iur following each major storm, an, inspection welk 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 infonn the City Engineer at once. A good quality rock, 8-inch to 16-inch (12-inch average), may be used to re-stabilize severely eroded areas along the creek. fiJ� r.a�zs r^' i « Gd,� k �..� na o.,•ti NJ�C T4 OL r -c D �0 i.If"A7 ;A iCn44 LM44 'SYdt—Ppry ryr w�..rf fvti.� C• ,?a!bY �7 j �rY?�/�� 5 ya. ��(>o.. ,_ b �/�c��• - yw Ir GA �s o.� (, mr�r_'.

To that end, it include, system and componen- description information, record keeping requirements, emergency operating measures, safety precautions, and relevant utilities 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 management of the sewerage sysW. The Sewer Supervisor and assigned staff are responsible for: '.. Knowing and understanding proper operational procedures. Keeping accurate records. 3. Properly managing operating funds. 4. Keeping supervisors and other necessary personae' 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- �ibilities. Coordination and communication between staff personnel is .perative to proper operation of the facility.

Honey Creek Pump Station is located just east of the sharp curved junction of HE Vth 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- tePted will be pumped to the existing gravitv sewer west of Edmunds 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 iflow infiltration, the City may also divert overtlow from the Sunset Pump Station. Since the pumping cost per unit of sewage is higher at Honey Creek Pump Station, it is desirable to maintain the Sunset Pump Station in continuous 0peratior. Ar G•..A.'rn 4k57ti 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 pawing 500 grm 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 portabl,� electric generator for emergency standby capability. The emergency generator is garaged at the highlands Pump Station at NE 12th Street and Olympia V nue NE. Sewage collected in the 72" .diameter concrete storage pipe to the southeast enters the pump station wet well via an 18 d;.ctile 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, which alternates lead on operation when sewage reaches the set level. The pumped sewage flows through 2200 LE of A" AWWA C900 PVC torte 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 d9viceS. A more detailed de',- cription can be found in Chapter Three, and in the Appendix,h—",*4eto;�Z; . ,ttnl Abbreviactons 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 avcid lengthy repetition in the te:t.

It is the only way to identify performance trends, track 0 8 M costs to pre- pare meanimrul budgets, and permit staff person, to be in control of pump station performance rather than always reacting, to unanticipated operations. Operation records show a record of flow and/or pumping time, and include such inforiatioo as electrical 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 docume'Led in writing for future reterence. The Sewer Utility Foreman shoal 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 per onnel n Unusual conditions (operational and maintenance) o Accidents to personnel o Complaints (odor, noise, leaks, etc.) o Flowrieter totalizer readings (periodic monitoring of remote flow measuring manholes) o Weather conditions 0 Dower Consumption (monthly or as available) o Running Time Meter Readings 0 --mergency Conditions (71, The above listed information should be recorded on a prepared `orm, 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 kept at the pump station, as well as any other designated shop location. Monthly and Annual Reports The daily operating log should be sunnarized monthly on a tone 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 krpt in a notebook at the pump station. Such records can reveal the weakne,:as 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 serrcing 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 ut operations to be done on certain dates. The items can be entered to advance on a memo calendar pad. For any program to be successful, it must be accepted by the 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) M I V W Operating Costs � � V t \J� Operating costs are not usually maintained by the Supervisor but y should be kept by the City's Finance Director. Records should be kept y 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 4 4z �`a cleaning materiali, 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 complr .e record of operating costs is maintained, budget- . t ing and cost control will be much easier and this information will help ,justify and document future sewer rate increases. 4 Inventory Records The Sawer Supervisor should establish and maintain a card file �l Q inventory of all replacement and maintenance parts including; D � R + 1Q 0 Part tare V' 41, u Model Number 00 Cost ,4 o Local Distributor t ! o Date Ordered o Date Used 4 ` u Delivery Schedule, if unusual + J 0 'nis information will prove very valuable in parts replacement, '.� ordering and budgeting. � �• ,y ` '' _ - _ ".L' v �• ✓s r , ,mot. � .. . �\ a .- ' : " 4GsJerRir;hf :T+il[I'E"tus4tltna ta....t Y ,�t 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-teomans 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.!

Should one pump fail to operate'FIA-4fr- 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 to be water lubricated (from protected potable suppl)). 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 pumps is M.O. Fowler Com- pany; 13440 SE 30th Street; P.O. Box 160; Ballevue, 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 B" 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 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. .fix�etIr"C.. 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 or, 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 bredkdowc, thus obtaining optimum service life. Please refer to the Appendix containing the Clow Pump literature pro- vided by the manufacturer fur specific guidance. The following trouble shooting guide will aid if 'specific problems arise.

Met 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. Sewoge solids left stranded by receding water levels will also decompose rapidly. wet wells dno 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 odr,rs. The timing of the intervals will depend on Sewoge temperature, frequency of automatic pumping and car. 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 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 g^ease entering the system should be gated to their source and eliminated. This problem usutily requires some good detective work on the part of the maintenance personnel. Gasoline stations, garages, machine shops, restaura d bakeries are prime suspects a Grease.M/0.04,rL 40 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 manufactured by Enpu-Cornell Pump Company. Stier, meeirted—bra 16 Five adjustable level floats are provided from the highest level, in descending order, they indicate: 1) High Level Alarm 2) lead Pump Uri (alternator changes lead pump after each pumping cycle) 3) Second Pump On 4) Pump Off 5) Low Leve' Alarm Floats number 1 and 5 indicatr abnormal emergency conditions, whi-h art indicated at the site by alarm and at the City Shop via telemetry equipment. It is important that conditions are Investiyated and remedied at once when alarms are triggered. Kunming 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 now many hours the pump operates each day.

Miscellaneous Equipment PiQinng. Piping requires periodic painting and occasional cleaning. It may alse be necessary occasionally to tighten flanges or replace gaskets in order to stop leakage. Then changing piping layouts, give particular attention to adequate and proper pipe supports. Be sure to note any modifications on as-built drawings. Knife Sate valves. The valves do not require lubrication. Maintenance r involves replacieg worn packir,c and tightening followers to prevent leakage around the valve stems. It is advisable to operate all valves period+rally by opening and closing them in order to ensure that the valve will not stick in either the open or cloyed position. 'L afer �_ .e ckf or SeNa�e Pumps. The station piping, fittings, and especially valves can become clogged and ere 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 casteliation's sharp corners on the nuts can catch rags end the cutter 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 fails to seat properly will let part or ail of the contents of the discharge piping drain back to the wet well, lowering the eflicienry of the statior. Rags caught in a properly adiusted check valve will soften or eliminate the normal click on closinc. mz- i k"O ` r ' /`� C�Ti 4•�`�� L�G'6 ZXGy.u,�islsi, Id . r. - . At if an improperly seated valve is suspect( ]: 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 !istening 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 show- "full open," and then stop it, watching the closing action of the lever and listening 'or the closing %lick.' You may have to stop the other pump if it is running, to to sure of what you 'ear. Sewer Maintenance General, A good sewer maintenance program involves continuously in- sPectiun and routine cleaning of the complete system as often as time, manpower and economy allows. Inspections will provide early detection of potential stoppages mid/or deterioration so that major problems car be prevented. An invaluable aid to a maintenance program is a complete set of current naps of the whole system. These :naps should be "AS-w@09 (F," showing grades, pipe sizes, types of raterials, 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. Mos+. 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) Y �' i ground settlement or shifting, etc. ;ide 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 flowi,ig 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 flowing with full velocitie; of less than 3 feet per second which are subject to buildup of grease such as in commercial areas where restaurants, garages, service stations, erc. are common. Quarterly inspections. Inspect all sewers where the iesign 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 bui'hup of grease. Annuel Inspections. Inspect all sewers which flow at least half full during noYmal 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, ,uagment 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 0 � following cbjectives: 1. Inspection of sewers and appurtenances, including testing of manholes and structures for hazardo. ises. 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 object.ves, 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 cocoon obstructions in sewers are roots, accumu- ,ations of grease, grit and miscellaneous debris. Normally when a stoppage occurs, manholes are inspected until the first downstream manhole with at..ormally low flow is found. This isolates the obstruction between the low flow or dry Ianhole 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 should keep in mind the possibility that when rodd'ng 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 obstructior can usually be washed downstream to the next manhole where it can be removed. Stoppages may also be caused by a break ui the line. If this is the case, generally a large amount of mod, sand or gravel washed into the system will reveal the problem. Sometimes a telltale sinkhole or depression may farm in the vicinity Of a break, a 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 oft,,n Saud 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 :leaning, depending on what equipment the City has at its disposal at a given tire. There are four common methods: rodding, bucket machines, "jets", and inflatable sewer balls. Complete stoppages caused by sand, grease, roots or other 'abris may be opened and sometimes removed by rodding equipment. Various rodding heads can be used tc 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 alonS the run of pipe blasting away ,he debris in the pipe and flushing it out with «e water used. Pump Stdtlon 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 it 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 211. oxygen by volume) is displaced by some other gas, which wy or nay not be toxic. Oxygen ae- ficienc, (less than 131 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- se..t 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 shcald 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 C,,ntroi Federation's Manual of Practice No. 1, Safety In Wastewater Works. If an area is suspected to be deficient in oxygen, ventilation shouldshould 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 iewage gas, or any flammable vapor is present in sufficient quantities. No snaking should bt *!'owed near any confined area that contains sewage or settled sewage solids. It electrical equipment is needed in such an area, pro- vide ventilation lung enough to displace any gases present withe air before operating the electrical equipment, 7r44ePv MP Kiat�� `II,S A Sl�t if IC, L.�LtfaE-� ri _ r_1 5i d 2S Lrif/ abm G� t a ;L4ar fi i�t scd C�C� Zf A-ew ctrical Mazar dw , __ " _ I A pumping facility inc�Ppttra tes sophis ic�electricai equipment.

Until such time as the interceptor is continued dowr. May Creek, the interceptor and Honey Creek Poap Station will receive highly variable flow. The interim flows through the interceptor c.onsist of: 8-inch gravity system in Union Street; the Honey Creek Pdik Pump Station No. 1 (if diverted by facility); overflows from Sunset Pump Station No. 2; and individual sewer services alor 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-n-ch SLlairpipe, polythylene DR 32.5. and is approximately 5,00C feet long from the Honey Creek Pump Station to Phase l: Manhole No. 1 in Onion 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 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 a usheo bvddiny and heavy fractured, Sour rotr. Ductile iron fittings were used for all star sewer connec Duns and cleaduuts. Cleanouts were installed at 400 feet spacing (8 sectlers of pipe) and oriented so that cleaning equipment can be used in the upstream directions. � W4 Pig9ing is ewe m-,1re widely recognized method of cleaning water and sewer lines and can be utilized for the long sewer inter- ceptor. The pia 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, Icc. of Seattle, and a copy of the manufacturer's specifications is inclu'ao in the Appendix. The PBS-B bullet type Polly Pig is a recommended type for the Honey Creek sewer interceptor. However, there are many types of pigs to the different applications and the manutacturer's representative should be cons9lted. Pigging the interceptor should be done at least annually. The manufacturer's recommended method of pigging shuuld be followed and must be subject to stets specific to this application. IW .i s Special maintenance considerations should be given to the first 400-foot section of the interceptor between the 6-foot diameter wet well and Phase 11 clean-out No. 1. Sewage backing up in the 6-foot diameter wet well will cause sewage flow ir, the interceptor to tempo,arily stop. This may result in increased build up of raterial to the pipe's inner wall and will accordingly require more fr•ec,uent cleuniny. �g • locdtiw, df the pulythylene sewer is generally toward the noddle 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 wirr was strung with the pipe to use as a i'/fs locator. The cledrouts for in-road location are centered directly over the pipe. Access Road and creek In addition to raintarrring the sewer interceptor, considerations must also ba given to the access drive and the structural integrity of the creek bed where the sewer is placed under the creek. Meekly 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 sh mps should be recorded and be referenced on the as- built drawings. Road embankments and areas adjacent to the bridge (30) .s+ bill I �tC�c Ito AdL Ad At.�4�T � «f,µ - - 4 \, t r ' � 41 AA � structures are more likely subject to severe erosion. Should mjor erosion take place, the Serer Supervisor should info,m the City Engineer at once. A good quality rock, 8-inch to 16-inch (12-inch average), may be used to re-stabilize severely eroded areas along the creek. 0,� 701, AN Ni 4 Ij �„2,tc��t,.u.�c.�-e�` spun .,-�a•�.a�L ��L,.t.�.�' 74 m A /)�-�,G�u .0 m.clt� G .j7*a-r-sue o f A-0 ,off-L ,G..,�.ts��►c.�.-,.�..c.� � 2. e.«d .o- •� cr•cZ�.cliers z� zj+Lc ,k s� `` �L,L mac. ctliw�I�-�GF'Zt�C �� .�/+�L�K�r .•�K�f�GG.GL..�. �o<,cc. j Nam•-.�- �,•.,,��Ei«,,,,�, ,��,,�,,:.. .� �- 04, •l v i i CITY OF RENTON HONEY CREEK PHASE 1 - PUMP STATION OPERATION AND MAINTENANCE MANUAL - HCW-L 2850-0 Ej 186 RE: HCW-L RESPONSES TO CITY'S COMMENTS ON ' AST DRAFT OF O&M MANUAL 'y!

Scott's leak checking progress at the Honey Creek pump station, I did some additional flow checks in the gravity sewer west of Kennydale. Malcolm Thomson and Don Jacoby of the Maintenance Department were at the site to view the instrument and to assist. Readings were .aade in Manhole 0040, the designated metering manhole. Manhole OF040 is on North 28th Street, midway between Park Avenue and Mead. The flow was small in the 30-40 gpn range. Apparently neither the Azalea lane nor the private condominium pump station near Kenn,dale School were on during this time. We 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 Manhole No. F040 Circular 50 12:47 PM Circular j 40 1:13 PM V Notch 40 1:16 PM 36 1:19 PH 36 1:22 PM 29 1:25 PM 28 1:34 PM 38 1:43 PM 43 rRr,rF tlNA'r„ n�yA ICKKt � M ,z f Y�A:_ct^__e/E .pppp._ Crsv Don Jacoby had some good thoughts on measuring. Don was a flow meaaureeent specialist with Gelco and thought the Flow Poke unit would be a goad 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 Ti,esday, 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 527 10:01 AM 525 10:03 AM 520 10:06 AM 515 10:09 AM 525 10:12 AM 487 10:15 AM 515 1U:19 AM 513 A little 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 pump on/off with walkie-talkie radio communication. Your Public Works staff is welcome to use the Flow Poke equipment we hate or we can assist too. I will further discuss this with you later, Sincerely, HAMiOND, COLLIER 8 WADE - LIYINVTONE ASSOCIATES, INC. _/•u4- Frederick G. Kern, P.E.

W. Scott company 9840 Carr Road Renton, Washington 9805t Re: Honey Creek Pump Station Dear Tom: The pump control system is very sensitive to the vacuum 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 operatioo 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 LL be more difficult to isolate. Part of the problem is a leak in the pump suction area. There 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 c. the vacuum system. Specifications do not state what frequency of adjustment or cleanout of the vacuum lines and float system is reasonable. However, based on the City's experience with similar stations, the adjustments at this station are too frequent and not considered a reasonable standard of practice. Specifically, the vacuum hose to the small impeller port plugs too easily. This problem was not apparent during pomp start-up testing because potable water was used to fill the wet well rather than raw sewage. We are working on improving the vacuum system by retrofitting some of the plumbing of the vacuum piping and chamber directly with H. 0. Fowler. How- ever, there are still air leaks based on vacuum pump operational period. We request that you assist the City in remaking-replacing any joints and fittings that have leaks. 1,. . 0W-1, 1.11., Mr. Tan Kitley December 1, 1986 Pvge Two Another discovery we made was that the pump seal water supply take off is ahead of rather than behind the backflow prevention b.f.p, device. The seal water supply should be replumoed to the downstream side of the o.f.p. The City needs to make the corrections quickly now that 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 rot a result of improper lack of maintenance by the City staff. PROPOSAL 1. The first job is to track down the leek in the system. A proper system should hold the vacuum prime for several days. The City has done some pressure testing of the suction side of the pump but has founa no leaks. We expect the cuntractor to assist in findihy leaks, disassembling- pieces, regasketing, and eliminating the leaks. The work needs to be scheduled when the pumps can be taken off line a short time during a non-rainfall period. We request that you call uary Morrison directly to arrange this work. 2. The fresh water pump seal discharge needs to be replumbed downstream of the 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 any costs that we fairly determine to be beyond the scope of the contractor's responsioility. There is an urgent need to correct the problems, and we will count on your support to get the job done properly. Thank you fcr your consideration.

Engineering Supervisor City of Renton 1'.oarcment of Public Works City Hall, 200 Mill Avenue Renton, kashiggton 98055 Re: Honey Creel: HCW-L f2850P3 Dear Bob: As discussed by telephone, we are working with Gary Morrison in trying to elimi• nate vacuum and other operating problems at the Honey Creek Station. Ir regard to the knife gate, 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, a^d 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 N.D. Fowler and Tom Kivley with R.W. Scott advising that leaks in the vacuum plumbing were suspe_ted. I also asked Fred Stevens to finish up details for an improved vacuum eductor piping that he had discussed with Gary Morrison. When George Hammond and 1 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 nany-up zones where tampon strings, rags or other debris can hang up and hold the check valve open. We discussed means of weld or epoxy filling the arm check plate cavities. These hang-up problems are not an equipment warranty issue. IwR.*o Cffi.R[ COs»a•Tw[ Mr. iiobert Bergstrom November 24, 1986 Page %,i Gary also mentioned that he had located the apparent trouble spot 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 N.D. Fowler's Eric Merklinghause of the plugging problem. Eric will discuss possible improvements to the small orifice at the imneller with the factory. The 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 d see-through line is recom- mended. In summary, 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.

Bergstrom APR 19A6 Engineering Supervisor City of Renton 200 Mill Avenue South Renton, Washington 98055 Re: Finish Up of Phases 1 and 3 Work Honey Creek HCW-L 2850 Dear Bob: The Clow Yeoman factory advised H.D. 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 N.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, ' .ttaC. Frederick G. KPrn, P.E. W14-89 .cn..ro r,uA+•u �wrvA.c.n. HAMMOND.COLLIER•WADE—LIVINGSTONE ASSOCIATES.INC.

Bergstrom City of Renton 200 Mil' Avenue South Renton, Washington 98055 Re: Honey Creek Sewer Improvements Program Statement for Services Invoice d19 Dear Bob: With January's billing, I've prepared a spread sleet illustiatinq all billirls including the storm damage repair services. Out of sequence monitoring, that exceeded our Amendment No. 3 authorized $77,500.00, is also included in this billing. 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 than concurrently, thus addit nal costs were incurred. Sincerely, Frederick G. Kern, P.E.
