Mr. Michael Grochala <br />September 20, 2016 <br />Page 2 <br /> <br />K:\Personal\Erin Heydinger\Lino Lakes\LTR - PROPOSAL - m grochala - WaterTowerSiting - 110816.docx <br />Task 2: Storage Size and Type <br />Using water use data and population projections, WSB will determine the size of storage tank the City will <br />require to adequately serve the future population. In addition to tank size, two types of storage will be <br />considered: ground storage and elevated storage. Ground storage can be at grade or sub-grade. Water <br />from ground storage reservoirs is supplied to the system via high service pumps. Elevated storage tanks <br />are raised and do not require a pump station; the elevation of the tank provides water pressure to the <br />distribution system. WSB will evaluate both types of storage for the City and will provide a <br />recommendation. <br /> <br />Task 3: Determination of Potential Sites <br />Once the type of tank is determined, we will evaluate potential sites for the tank. The sites highlighted in <br />TKDA’s Water Treatment Plant Feasibility Study, dated September 17, 2007, will be analyzed in this <br />study. Up to three additional sites will also be studied. Any additional sites studied will be determined <br />using GIS and will be based on location within the water distribution system, gr ound elevations, likely soil <br />type, and ownership. <br /> <br />Task 4: Water Distribution System Modeling <br />In 2015, WSB created an existing and ultimate water system model in WaterCAD that will be used for this <br />study. The existing system model will be updated with any watermain changes that have been made <br />since its creation. The model’s ultimate water demands were based on the City’s 2030 Comprehensive <br />Plan. Since that time, the Metropolitan Council has released new population and water demand <br />projections; the City’s ultimate water model demands will be updated accordingly. <br /> <br />Once the model has been updated, scenarios will be created to evaluate the impact of adding storage at <br />each of the sites identified in Task 3. If necessary, alternatives to each scenario will be included to <br />determine how to successfully integrate storage at each site. <br /> <br />Task 5: Cost Estimates <br />Approximate cost estimates will be provided for each site considered. The cost estimates will be based on <br />the findings from tasks 2 through 6. The estimated costs included in the final report will include a <br />construction contingency and indirect costs. Specific design requirements unique to each site will be <br />considered. <br /> <br />Task 6: Prepare Feasibility Report <br />WSB will deliver a detailed feasibility report outlining the methods and results of the study. The report will <br />include a final recommendation based on cost and design requirements. The findings from the storage <br />evaluation, site determination, geotechnical evaluation, water distribution system modeling, and cost <br />estimates will be included in the report. The report will allow the City to move forward in property <br />acquisition (if necessary), design, and construction of the storage facility. <br /> <br />Cost and Schedule <br />The estimated cost to perform Tasks 1 through 6 described above is $14,900 billed on an hourly, not-to- <br />exceed basis. The following presents the cost breakdown for each task presented in this proposal. These <br />fees do not include geotechnical services. A proposal to obtain soil borings and provide a geotechnical <br />report will be submitted to the City after the potential water storage facility sites have been determined <br />during the study phase. <br /> <br />Task Number Description Cost <br />1 Project Management and <br />Coordination <br />$1,900 <br />2 Storage Size and Type $2,400 <br />3 Determination of Potential Sites $3,400 <br />4 Water Distribution System <br />Modeling <br />$3,700 <br />5 Cost Estimates $1,800 <br />6 Prepare Feasibility Report $3,900 <br />Total Direct Labor Costs: $17,100
