<br />gallons. While there are not specific recommendations for a population of approximately <br />125, interpolation leads to a recommendation of 25,000 gallons for a population of 125 <br />residents. To be conservative, the recommended storage volume to serve the Goodman <br />Point area is 30,000 gallons. Design criteria for the water storage tank are as follows in <br />Table VII-I. <br /> <br />Table VII-I: Water Storage Tank Design Criteria <br /> <br />Description <br />Population Served <br />Average Usage <br />Total Daily Demand <br />CDPHE Minimum Storage <br />Proposed Storage Tank Volume <br />Diameter <br />Height <br />Head Required (to fill) <br />Head Available <br /> <br />Design Condition <br />125 <br />100 gpcd <br />12,500 gallons <br />25,000 gallons <br />30,000 gallons <br />16 feet <br />20 feet <br />149 feet <br />242 feet <br /> <br />The storage tank will be located at the southeast corner of County Road P and County <br />Road 17 near the fire house as shown in Figure VII-I. Water from the existing MWC <br />distribution system has sufficient pressure to fill the water storage tank without the need <br />for additional pumping facilities. Currently MWC is looking to donate a 131,000-gallon <br />tank in substitution for the 30,000-gallon tank pending approval by the MWC board. <br />This tank will sufficiently meet the above design criteria while reducing project costs. <br /> <br />4. Pumping Station <br />Due to the elevation gain within the proposed project area, a booster pump station is <br />required. This will be a package pump station with two pumps, one duty and one <br />standby, with space to add a third should growth increase more than anticipated. It is <br />required by the CDPHE that there be a minimum of two pumps in each pumping facility. <br />Each pump will be capable of delivering the maximum daily pumping demand per <br />CDPHE design criteria. The pumps will be driven by VFD to maintain a constant system <br />pressure and convert single phase power to 3 phase. Single phase is the only power <br />available at the proposed site. The VFD will also enable the pumps to meet all demand <br />conditions. <br /> <br />The pump station will be located adjacent to the water storage tank at the southeast <br />corner of County Road P and County Road 17 as shown in Figure VII-2. The pumps will <br />draw water from the water storage tank and pump through the higher elevations of the <br />distribution system. The pump station will be located above ground with an approximate <br />footprint of 25' x 12' (300 ft\ A backup diesel power generator will be included to <br />maintain minimal essential service. Design criteria for the booster pump station are as <br />shown in the following table. <br /> <br />Goodman Point Water Association - Preliminaty Engineering RepOli <br /> <br />19 <br />
