The 350-foot pressure zone was studied to define its limits, and domestic and fire flow demands were determined. These demands establish the number and capacity of domestic and fire pumps at the proposed pump station. 350-FOOT PRESSURE ZONE IN THE TALBOT HILL AREA The 350-foot pressure zone in the Talbot Hill area is shown in Figure 1. This zone was divided into a northern and a southern area in order to define the limits of the existing Talbot Hill Booster Pump Station which distributes water to the northern area, and the proposed South Talbot Hill Booster Pump Station, which will distribute water to the southern area. Th: area of the northern part of the 350-foot zone is approxi- mately 87 acres. The area for the southern part is approxi- mately 350 acres, of which the Valley General Hospital occu- pies approximately 30 acres. Since the hospital system de- mands were computed separately from the domestic demands, its crea was subtracted from the total southern area for an adjusted southern area of 320 acres. It was determined by field observations that approximately 75 percent of the northern area in the 350-foot pressure zone is presently developed while approximately 20 percent of the southern area is developed. 350-FOOT PRESSURE ZONE SYSTEM DEMANDS Reference to Appendixes 4 and 5 of CH2M HILL'a 1965 re,urt un the Renton water system gives the basis for computing system demands. in a developing area such as Talbot Hill , the maximum day demand can be computed either on an area or population basis. An area basis is used here. The criterion for the area basis is a rate of 100 gallons per day per 1,000 square feet of total area, with a reduction of 30 percent for paved areas. This is equivalent to 2.1 gallons per minute per acre. Using this factor in conjunction with previously stated acreages, the present and ultimate system demands were cal- culated and are shown in Table 1.

JRM :j ` z , APKIk_ 19a0 ❑ are as defined in the table. Maximum hourly demand was cal- culated as twice the maximum daily demand. The demands for the southern area include an estimated maximum day demand of 120 gallons per minute (gpm) to the Valley r.eneral Hospital. This hospital flow was estimated based on the past 12 months' meter readings adjusted upwards by a factor of 1.5 for future hospital expansion and 1.5 for the ratio of maximum month to the maximum day. Table 1 350-FOOT PRESSURE ZONE SYSTEM DEMANDS FOR THE. TALBOT HILL AREA System Demand (gpmt Time Period Area Location Presents Design Ultimatec Maximum day North 140 - 180 Maximum hour North 280 - 370 Maximum day South 250 390 790 Maximum hour South 5'.0 780 1,580 a Present system demand for approximately 75 percent develop- ment in the northern area and approximately 20 percent b development in the southern area. Design system demand for approximately 40 percent development. cUltimate system demand for 100 percent development. The southern service area would consist of mostly single-family residences, the Valley General Hospital, minor commercial/ office use, and minor apartment development. 350-FOOT PRESSURE ZONE. DOMESTIC PUMPS Northern Area The existing Talbot Hill Buoster Pump Station must meet present maximum hour demands. The existing 500-gpm variable-speed pump is adequate for this, and the pump can also provide for the ultimate maximum hour. Thus, this pump is adequate for the present and will be able to help meet present demands in the southern area. Southern Area The proposed South Talbot Hill Booster Pump Station must meet present maximum hour demands and design maximum hour demands. Ultimate maximum day demands must be met after the future reservoir is constructed. � r Two constant-speed pumps are recommended for initial installa- tion with provision for a third at a future date. In order to meet the design maximum hour demand, the recommended pump capacities for initial installation are 250 gpm and 600 gpm, for a total of approximately 800 gpm if both are running. The recommended pump capacities would also meet the ultimate maximum day deman, . The need for, and capacity of, the future pump will depend on when the future reservoir is constructed. The constant-speed pumps will require pressure-relief valves to prevent the pumps from over-pressurizing the system at low flows. They will also require control valves to prevent surges in the system when the pumps are started. Installation of a variable-speed pump at the proposed South Tdlbot Hill Pump Station is not recommended because of antici- pated control problems due to adverse interaction with the variable-speed pump at the existing Talbot Hill Pump Station. No standby power is recommended for these pumps because water is available from the northern area of the 350-foot pressure zone and from the adjacent 196-foot pressure zone. Addition- ally, the future reservoir will provide water during major breakdowns. This pump selection will give r oility and standby in the event of mechanical failure and will meet the range of system demands experienced from the winter low to the summer high for the defined design period. 350-FOOT PRESSURE ZONE FIRE PUMPS Northern Area Fire flows will be supplied by the existing pump at the Talbot Hill Booster Pump Station and two existing pressure-reducing valve stations. Southern Area Fire flows will be supplied by the installation of fire pumps at the proposed South Talbot Hill Pump Station. An estimated maximum flew of 5,000 gpm will be required at the Valley General Hospital following construction of the currently planned expansion. Two pumps are recommended to provide fire flow of 2,700 gpm each, in addition to the maximum day domestic demand. No standby power is recommended for the fire pumps. In the event of power failure at the proposed pump station, lesser fire flows can be obtained from the northern area of the 350-foot pressure zone, the proposed pressure-reducing valve station connection with Water District No. 58, ,ind an inter- tie to the adjacent 196-foot pressure zone. Each fire pump will require a control valve to prevent surges in the system when the pumps are started. Fire flows in the future would be provided by the future reservoir. INSTRUMENTATION AND CONTROL The domestic pumps will supply water to the 350-foot pressure zone in response to pressure. The pumps will be turned off in response to low flow. Instrumentation and control of the pump station will be designed in conformity with CH214 HILL'S 979 report entitled 'Supervisory Control and Telemetry System" _., the city. The following basic control and monitoring features are recommended fnr the domestic pumps; 1. Manual selector for each pump to function as a lead, first lag, or second lag pump, 2. Manual override of the automatic pressure/flow control system for starting and stopping each pump (with red warning light in manual mode) . 3. An indicating 'ON* light and elapsed time meter; elapsed time in hours with manual reset of meter. 1. Pump station failure alarmed centrally and/or at the police station. 5. Record and totalize flow from the pump station. The fire p�wps will supply water to the 350-foot pressure zone in response to pressure. They will be turned off manually. Control and monitoring features will be similar to those provided for the domestic pumps. 1-- :7c._� r __ hr n u"•'6� lQsiw'�ut� vno Lo _1t o� _or---- rnoxtt ra.1/ 36 3/ A t___ ;ti-.

I WS:pc enc. a/s CONTROLS SYSTEMS METERS VALVES INSTRUMENTS (n,�D c�p� SOUTH TALBOT HILL PUMP STATION INITIAL STARTUP OPERATION DOMESTIC PUMPS General There are two domestic pumps. One has a capacity of 200 gpm at 200 feet and the other 600 gpm at 200 feet. The pump head is for filling a future reservoir. Until the reservoir is built the pump head Bill be limited by a pressure reducing feature on the pump discharge control valve. The pressure will be limited so that the domestic pumps allow primary pumping operation in tha 350 zone by the variable speed pump located at the North Talbot Hill Pump Station. The two domestic pumps will operate only when the variable speed pump cannot meet demand in the 350 zone. Starting Normally pump starting will be automatic. Starting will be initiated from a pressure switch after an adjustable 0 to 30 minute time delay. The time delay prevents unnecessary starting of the domestic pumps on low pressure. After the MISC11-C (1) D2 time delay times out, the pump starts. The pump control valve pilot solenoid valve energizes and the valve starts to open with a 60-second time delay starting. The control valve slowly opens. Valve opening time is adjustable and may be varied from 30 to 60 seconds. The valve limit switch closes its contacts when the valve is 5 percent open, and the pump remains running. The CO-second time delay shuts down the pump if the limit switch contacts do not close, indicating the control valve did not open. Stopping Normally pump stopping will be automatic. Stopping will be initiated from an adjustable low flow reading from the flow meter. The low flow reading is adjustable. After the low flow occurs, the control valve pilot solenoid valve is de-energized and the control valve starts to slowly close. A 60-second time delay starts. The valve limit switch opens when the control valve is 5 percent open and the pump motor is turned off. The 60-second time delay shuts off the pump if the valve limit switch did not open before 180 seconds occur, indicating that the valve did not close. After the Pump shuts off, an adjustable 0 to 30 minute timer starts which prevents the pump from automatically starting until the delay time occurs. This prevents the pump from cycling, that is, coming on again immediately after shut-off. MISCII-C 12) D2 FIRE PUMFS General There are two fire pumps. Each has a capacity of 3,500 gpm at 210 feet and 5,000 gpm at 140 feet. The pump head is to provide sufficient flow to fight a fire either at the top or extremity of the 350 service zone. One pump serves as a backup. Both cannot operate together. Each pump has a control valve to bring the pump on or off line smoothly. Normally, a fire pump will be started on low pressure in the system. Once a fire pump is on, it must be turned off manually. The principle reason for manual shutoff of a fire pump is to eliminate automatic pump shutoff during a fire. Presently, the fire pump will cause high pressures in the system when the pump is producing low flows. The proposed solution is to provide a pressure reducing feature tc the control valve. Starting Normally pump starting will be automatic. Starting will he initiated from a pressure switch. The pump control valve pilot solenoid valve enerqizes and the valve starts to open with a 180-second time delay starting. The control valve slowly opens. Valve opening time is adjustable and may vary MISC11-C (3) D2 from 45 to 180 seconds. The valve limit switch closes its contacts when the valve is 5 percent open, and the pump remains running. The 180-second time delay shuts down the pump if the limit switch contacts do not close, indicating the control valve did not open. Stopping The pump will be stopped manually. when the switch is placed in the off position, the control valve pilot solenoid valve is de-energized and the control valve starts tc slowly close. The valve limit swiich opens when the control valve is 5 percent open and the pump motor is turner' off. The 180-second time delay shuts off the pump if the valve limit switch did not open before 180 seconds occur, indicating that the valve did not close. MISC11-C (4) D2 Initial Pump Station Control Settings The following will be the initial control settings for startup of the pump station. Field adjustments will have to be made prior to final settings.

Described below is the scope of work that we discussed. South Talbot Hill Water System Operations Modifi-ations Phase I: North Talbot Hill P.S. Modifications Task 1. Review N. Talbot Hill ^.S. operation and controls. Task 2. Develop modifications to the variable speed pump control from a hydraulic actuated system to an electronic pressure sensing device and controller. Prepare a sketch and description for installation and equipment purchase. Task 3. Install controls developed in Task 2 with City crews or local instrumentation and control supplier. Task 4. Set controller operating regime in field by simulating ^ystem demai, ls via hydrant flows. Phase II: South Talbot Hill P.S. Operation Task 1. Operate both north aid south Talbot Hi.1 P.S. to determine their operating regime. xuu.ar,.. ..n ca:. �,. . . ,ia.r,.•,uaa,nmKn.n W11w sw�n;a., Mr. Ron Olson Page 2 Juiy 28, 1982 5871.71 This will be accomplished by monitoring the pump station operating times and by simu- lation system demands via hydrant flows. Task 2. Determine existing system operation regime (review Task 1 results) . Task ?. Develop system operation description of existing system and propose alternative system operation regimes. Phase III: South Talbot Hill P.S. Modifications The tasks for this phase will be determined from the Phase II results. The cost range for the above scope is $7,500-8,200, which in- cludes $2,500 for the Phase I equipment, but does not include installation costs for the equipment. It is our unr ,rstanding that City crews will isolate the hospital from the 350-zone ar.d check the system for pressure variations. The results of this field test may modify the auove scope, so prior to finalizing, we should be nr Pied of _he results. We are prepared to work with the City, their control supplier, acd Gardner Engineers to resolve the Talbot Hill water system operation to your satisfaction.

This work followed our meetinq of April 25, during which we discussed recent control problems and the testing we had conducted that evening to demonstrate the problems, 1nc3 '3d herein is a list of the problems iden- tified at the e Ing. Also attached is the pump curve drawing on whic! re indicated the various pressure set points establinneu for pump station control. These points are identical to those recommended in our December 9, 1981, letter. Discussing now the procedure adopted on May 15, the PRVIs !0" Iing into the 350 zone from the 590 zone were first ch.:cked for proper operation. All pumps at the South Talbot Hill PLmp Station, along with the 350 zone variable speed Pump at G.-, Talbot Hi31 Pump Station, were turned off. The 3-inch and 8-inch PRV's at South 19th Street were found set to maintain on the downstream side 82 and 80 psi, re- spectively, at valve elevation i62, hydraulic grade line (HGL) 351 and 347. These PRV's were adjusted to maintain 62 and 59 psi. The 3-inch and 8-inch PRV's at South 23rd Street, eleva- tion 219, were found set to maintain 60 and 45 psi, respec- tively (HGI. 358 and 323) . The 3-inch PRV was adjusted to maintain 31 psi (HGL 291� . We were not able to adjust SAI eMkr 'SIN)11Py>%r"m•SI &AL•.w• 1Va.nmpun 4tllMV aln AS itAKI Mr. Ron Olson Page 2 June 1, 1984 5645.71 the 8-inch PRV) either the valve or the adjustment device was not operating. We had intended to adjust the 8-inch valve to maintain 28 psi (HGL 283) . This valve was left closed. While adjusting the PRV's at South 23rd Street, the PRV's at South 19th Street had to be closed. Consequently, the 350 zone demand exceeded the supply through the 3-inch PRV at South 23rd Street, and customers began calling about lack of water service. Following the attempted adjustment of the 8-inch PRV, the 350 zone variable-speed pump and South 19th Street PRV's were again turned on. City staff will need to follow up on repair/adjustment of the 8-inch PRV at South 23rd Street. Please note that PRV set points and ground elevations as stated in Table 1-6 of the Comprehensive Water Plan are incorrect for these two stations. Although we did not closely observe the system pressure maintained by the variable-speed pump, it appeared to main- tain a system HGL near 360 feet (137 psi measured at South Talbot Hill Pump Station) based on subsequent testing re- sults obtained there. City staff should verify that the variable-speed pump does maintain this HGL. The pressure relief valve at South Talbot Hill Pump Station, elevation 49, was next set to relieve at 139 psi (HGL 370) . We found that its speed control valve was almos, closed, which prevented water pressure from moving the valve dia- phragm. This was the cause of the valve's failure to close during testing on the evening of April 25. We then simulated additional system demand by opening the fire hydrant near South Talbot Hill Pump Station. Uomesr.ic Pump No, 1, elevation 44.5, came on at about 120 psi (HGL 322) . The pressure switch was adjusted to turn the pump on at 128 psi (HGL 340) . The PUMP control valve was found to close at 122 psi (HGL 326) . The close point was adjusted to 130 psi IHCL 345) . The valve failure timer was found set at 30 seconds; it was adjusted to 100 seconds. The valve closure speed was found to be 3+ minutes; it was adjusted to less than one minute. Domestic Pump No. 2 was adjusted in the same way. It was found to come on at about 110 psi. Pump No. 2 gauge read 110 psi while Pump No. 1 gauge, in which we had the most Mr. Ron Olsen Page 3 June 1, 1984 5645.71 confidence, :ead 115 psi. All subsequent readings and ad- justments for Pump No. 2 were made using Pump No. I gauge. Pump No. 2 pressure switch was adjusted to turn the pump on at 119 psi )HGL 320) . The pump control valve was found to close at about 128 psi. It was adjusted to close at 128 psi (HGL 340) . The valve failure timer was adjusted to 100 sec- onds ar.d the valve closure speed was set at less than one minute, similar to Pump No. 1. Following adjustment of Domestic Pump No. 2, both domestic pumps and their pimp control valves were made to run through their sequences of operations by again simulating system demand with the nearby fire hydrant. Both operated prop- erly. All of the above pressure ..et points are subject to gauge accuracy and should be verified periodically with cer- tified gauges. We now refer to the following list of problems noted in the April 15 meeting. o Fire pump starts and stops apparently triggered by a telemetry problem. o Domestic pump starts and starts with vent fan operation. o System locks up and does not go through the complete sequence of opera ton. o System shuts down frequently. o Fire pump Cla Valve does not close responsively. o Domestic Pump No. I turns on when switch is off. o Pump starts when master switch breaker is placed to ON. The Cur_ t status of the identified problems is: 1. Fire pump on/off occurrence seems to be a telemetry interference problem. The cause of the random opera- tion of the fire pumps could not be determined. The only plausible explanation is that noise on the tele- metry system causes the pumps to start and stop. We i v Mr. Ron Olsen Page 4 June 1, 1984 5645.71 suggest that an interlock be provided in the pump sta- tion telemetry panel that inhibits the "ON" command from the telemetry system when the pump is selected to "AUTOMATIC." This would prevent a random "ON" command from starting the pump while it is in automatic but would not prevent noise-induced random operation if the Pump is selected to "OFF." The attached drawing indi- cates the required changes. Stead and Baggerly, who designed and installed the telemetry, could make the required changes in several hocrs. 2. Domestic pump starts and stops with vent fan control. The only way this could occur is by h -Lng a direct electrical connt -tion between the two control circuits. The control wiri..g for the domestic pulps was checked. We could not find any connections between the two con- trol circuits. The only conclusion we can arrive at is that two wires in a wire bundle were somehow shorted and that, during our inspection, the short. was removed. 3. System locks up and is difficult to reset. We believe lock-up occurrences have b,, •n minimized through adjust- mert of set points. City staff knows how to reset equipment inside the panel. Reset switches on the panel door would simplify the task but are not essen- tial. 7. System shuts down frequently. This problem has been resolved, to the best of our knowledge, through adjust- ment of set points, timer changes, and replacement of the flow switch. The flow switch that shuts down do- mestic Pump No. 1 was determined to be defective. The indicator and switch unit were replaced using the spare unit. The spare switch was tested and performed satis- factorily. The defective meter relay can be either repaired or replaced througl. a company called LIL, phone number 761-0880. 5. Fire pump Cla Valve does not close. we believe thie has been :ebolved by adjustment of the valve closure speed. It should be rechecked by the City staff. 6. Domestic Pump No. ` starts when switched to OFF. We believe this has been resolveu with iring changes as noted in It.,m No, 2 above. • s Mr. Ron Olsen. Pace 5 June 1, 1984 5645.71 Pump starts when MS breaker is placed to ON. This problem could net be duplicated at the time of our tests. Assuming that the highest ground elevation served in the 350 zo ,e is 250 feet as stated in the Compreh-nsive Water Plan, the minimum service pressure at this elevation will bni 15 to 24 psi, given the PRV settings indicated on the at- tac;:ed pump curve drawing. While we understand that the DSHS-recommended minimum pressure is 30 psi, we do not be- lieve that the PRV's feeding the 350 zone can be set to maintain this higher pressure without interfering with oper- ation of the South Talbot Hill constant-speed pumps and the variable-speed pump. As we discussed, these PRV's could be adjusted to the higher pressure if a systemwide control system were installed to electronically interface constant-speed pump operation with the variable speed pump and PRV'=. at Talbot Hill. The hy- draulic interface in the existing system requires a broader pressure control range, which could be significantly reduced if a more sophisticated control system were provided. we are convinced, however, that the control system as designed is worKable. Given proper adjustments, the South Talbot Hill Pump Station should operate properly. As Indicated above, better zo:.n control can be achieved by using a programmable device that provides cverall zone con- trol. The programmable device can take several forms, in- cluding a programmable controller or a central supervisory control system. Since the City is currently designing a central supervisory control system, we suggest that the zone control be provided as a part of that system. All of the above meetings, investigations, and field work (which included replacing failed hardware, setting PRV pres- sures, and adjusting valve speeds and timers! have been done at our own cost, in excess of 50 man-hours. We are not at present satisf,ed that there is not some demand or condition in the water system that is affecting the operation of the two pump stations and pressure reducing valves. We are Mr. Ron Olsen Page 6 June 1, 1984 5645.71 therefore addressing a further letter to you suggesting some additional investigation of conditions within the water system. Sincerely, Arthur L.

We propose, as discussed on May 25, that Barry Barnes work with c_ty personnel to accomplish the following tasks: o Review an up-to-date map of the south end system o Physically check the open/closed status of all valves of any significance in controlling flow in the system o Discuss with city personnel the possibility of a customerlsl creating a mcrertary large demand o Meet with the Valley General Hospital plant engineer by appointment arranged by the city and accompanied by a city staff employee o Investigate the possibility of at- , a portable pressure recorder to the hospital service to detect pressure fluctuations c side of tLe meter o Locate portable pressure recorder. ,arily in the south end system as determined .vieftcial ISM II401 M.•nue 5 E WOrsur Wasb,ryWn 1NMN ab.4515an Mr. Ron Ols n Page 2 June 1, 1984 5645.71 o Re, iew exirting city records on pump station or system operation potentially affecting the south end We would intend that Barry work with your staff at an hourly gate of S71 plus expenses. Typing and reproduction of a briet report and review of the report would be at lower rates. Close cost control would be exercised with a maximum expenditure of $3,000. Should there appear to be no benefit in proceeding beyond a less costly point, the work would be terminated zs you might decide. We would bill you upon com- oletion of the work.
