1974 10 152020 ^'CITY COUNCIL MEETING:Special Meeting October 15,1974 V.--Council Room,City Hall 8:00 P.M. Members present:Councilman Norman Johnson,Michael Boyle, Gordon Ebbert, Don Swanson and Otto Skaug.Councilman Hill and Moe were not present. «Mayor Ebbert called the meeting to order specifically scheduled fora Water System Operational i J .Analysis Report for the City of Moses Lake by Stevens,Thompson &Runyan,Inc., ofSeattle. Hal Murray,Dirk Van Woerdenand George Nordby of STRwere present.« Hal Murray,Vice President and Manager of the STR Seattle Branch,suggested an open meeting /S* for Council and those in attendance to ask questions as the report is being presented,and turned over presentation of the Analysis to George Nordby,Project Engineer. George Nordby first gave a little background of why the City Staff wanted to do this study initially. OnMay 22, 1973, the City of Moses Lake entered into a contract with STR to conduct an analysis of water system operations.The scope of workwas structured to examine and find solutions forspecificproblemareasknownby the City as well as to analyze and recommend solutions for pro blems discovered during the course of the study.Some of the problems the city experienced are •v*excessive pressures adjacent to some wells while under certain conditions,pressures in the ex tremities and some of the higher areas are considered too low.Also during periods of peak demands the consumption is greater than the system supply provided by the wells and reservoirs.Under these .conditions there is a continual lowering of the water surface in reservoirs,resulting in degraded service pressures. Adigital computer program was selected to adequately analyze the normal operating characteristics of the existing system and simulate various system deficiencies and needed improvements and modifications.Also data from the Ground Water Study recently completed by Robinson &Noble,Water Geologists from Tacoma,was .used as input into the operation analysis with respect to the wells' capability of provided needed water. RECOMMENDATIONS:(Lakeview Terrace Area)Adiagram presented outlined the three zones in the system,Pressure Zones 1, 2, and 3. These areseparated by pressure reducing stations,whichundercertain conditions will admit high water from a highzone to a lowerzone. Oneof the things recommended is to divide Zone 2 into Zone 4 in the. Lakeview Terrace area around the School and Big Bend College area/Upper Lakeview Terrace area) and the balance of the area (Garden Heights,East Montlake and Montlake)remain in the existingZone2. Separating these two zones would inter-connect the existing reservoir #2 and provideadequate pressure to the area lower in elevation. Anew Reservoir No. 5 will be added to serve the Upper Lakeview Terrace area,after drilling Well No.11.Also a Booster Station as a viable means *—'of 'providing supply to either Zone 4 or Zone 2 in the event a well is being repaired or the pump is "being pulled because of problems.Modifications are recommended in the existing booster pump station as a secondary source of supply to Zones Nos.2 and 4. Also add an eight (8)inch water main from Division Street to Skyline Drive,which has been accomplished to date.'Zone 3 does not exhibit any significant problems or deficiencies. (Peninsula Area:) There is presently no reservoir in the entire Peninsula area,Reservoir #1 provides pressure to the Peninsula area,and the system indicated,in the field as well as on computer,that under certain operating conditions of Well #4,they have either low pressure or pressure too high.Recommend a Reservoir #4,which is referred to in the Comprehensive Plan as the 'Peninsula Reservoir',and that should solve that problem. After putting proposed Well #11 into Zone 4,additional supply for the Peninsula/Central Business area could be obtained from Well #31 in the Westlake Area,and bring water from it across the Lake,and that supply could be for Zone 1 and would have a balance of supply and storage for that area. ESTIMATED PROTECT COSTS: Divide Zone 2 into new Zone 2 and 4 -includes pressure reducing station,connecting Reservoir #2 to new Zone 2 and reconnecting Well #5 to new Zone 4 - ESTIMATED PROJECT COSTS =$109,000 Add Well #11 to new Zone 4 -includes well,pump,pumphouse and transmission mains ESTIMATED PROTECT COSTS =404,000 Add Reservoir No.5 in new Zone 4 -Includes transmission main ESTIMATED PROJECT COSTS =556,000 Add Well No.31 to Zone 1 -includes transmission main-ESTIMATED PROTECT COSTS =307,000 Add Reservoir No.4 -includes transmission mains ESTIMATED PROTECT COSTS =832,000 Modify Booster Station ESTIMATED PROTECT COSTS =115,000 George Nordby proceeded to explain how the operational analysis was accomplished along with explanation of the Plates and Graphs included in the report submitted. A number of residents from the Upper Lakeview Terrace area were presentand inquired as to time element for relief of the water pressure problem. 5T '• A Z -,-r -•* CITY COUNCIL MEETING: Council Room,City Hall Special Meeting:2 October 15,1974 8:00 P.M. George Nordby stated that Referendum #27 financing is getting in order,and preliminary engineering design is in the process. City Manager Chet Waggener added that the Referendum #27 project is -.$50,000,000 in water bonds that were voted in by the public a few years ago.We do have applications in for every one of these projects at this time.We do not have any way of knowing how our projects will rate in priority array as against projects elsewhere throughout the state.$9,000,000 of that $50,000,000 has been released at this point.The people who administer Referendum #27 funds are requesting from the Legislature to make $25,000,000 available in the next biennum.If the request is granted by the Legislature,then they are also proposing that they actually make commitments for those funds in the first two quarters of 1975,so that by July 1975 they can actually make the monies available for construction.These grants provide 40%of what they consider eligible costs. He stated that we cannot answer questions as to what can be done quickly.The problem is that if we put In larger boosters that would increase the pressure in the Lakeview Terrace area;it would also overflow the reservoir.The only real answer is to simply put in a reservoir at higher elevation that will feed back and give extra pressure.We are not looking at a 1990 figure,we are looking at a couple of years. The air problem,he added,is separate from the pressure problem,and we have had video scanning and other work done on three wells at this time.The air,principally in that area,is coming from Well #8,and have not had a scan on it at this point because we just cannot take that many wells out of the system at one time.The Ground Water Geologist tells us that we are getting a cascading of water from upper aquifers that Is falling down as we pump it deep,and trapping air as it goes down. Probably will have to check that well and put casing in and seal off some of the upper water.Also Well #5,near the Lakeview Terrace Tank,is presently out of commission.The pump has been pulled, and doing checks on it.We suspected and found that the pump is also severally worn and needs to be replaced,and a new pump is on order.With that pump back in operation,it will most likely help the problem in that area to some extent.' The City Manager emphasized,after inquiry from some of the residents attending the meeting,that the cost of any of the water improvements have been built into the water rate structure and paid for out of the utilities,and there will be no special assessments.The City has received a Referendum #27 grant ior drilling Well #11,although this has been held up regarding a permit from the Department of Ecology. The Department will possibly start allowing permits about the first of next year. Inquiry was made regarding pressure in the area for fire flow.The City Manager explained it is not that big a problem for fire control,because the Fire Department automatically puts a pumper directly on to the hydrant.
