The required water supply demand are currently available from MHCSD's System, but both <br />water treatment and water storage capacity must be purchased from one of the Mountain House <br />Master Development firms. (Refer to attached Water Supply Capacity Agreement Exhibit 3) <br />between Pinnacle Ridge, LLC (Applicate) and Mountain House Investors, LLC (Developer). <br />A 12" PVC waterline was installed within the street right-of-way of Bethany Road that services the <br />existing Waste Water Treatment Plant (WWTP). A 12" water line stub was installed to the property <br />line of the subject parcel for future connection with the construction of the WWTP waterline <br />project. The proposed development will connect to this stub for new fire services, domestic water <br />services, and irrigation services. District approved water meters, double detector check valves, <br />and other required appurtenances will also be installed. (Refer to Exhibit 1). <br />WASTEWATER: <br />MHCSD is responsible for collection, treatment, and disposal of wastewater. During 2007, the <br />existing Phase II Wastewater Treatment Plant (WWTP) treatment system and associated <br />infrastructure were replaced with a 3.0 MGD Sequential Batch Reactor system. Lined aeration <br />lagoons exist for emergency treated effluent storage. Treated effluent is discharged to Old River <br />under orders and permits issued by the Regional Water Quality Control Board. A major expansion <br />of the WWTP is expected to start construction in the spring of 2021. This expansion will increase <br />treatment capacity by 2.4 MGD, creating a total treatment capacity of 5.4 MGD. <br />Approximately 80% of service area for wastewater collection system drains by gravity to the <br />WWTP through a backbone collection system. The remaining 20% is pumped to the treatment <br />plant through lift stations and force mains. At the present time MHCSD does not recycle any <br />treated effluent. <br />The subject property is currently serviced by an onsite septic system with 3,000 gallon solids tank, <br />and leach field. This system will be removed and/or abandoned once connected to MHCSD <br />services. <br />Preliminary calculations for the proposed development's sewer demand are estimated to be as <br />follows: <br />Sewer: Average Dry Weather Flow (ADWF): 1,600 Gallons/Acre/Day2 <br />ADWF = 1,600 gpd/acre x 2.86 acres = 4,576 Gallons/Day <br />Peak Wet Weather Flow (PWWF) = Design Flow = Peaking Factor (PF)3 x (ADWF) <br />PWWF = 4,576 GPD x 4.0 = 18,304 Gallons/Day <br />2 Table 5.2.1, sewage quantities, MHSCD standard specifications & details, Limited Industrial Use <br />3 Peak Factor per Detail No. SS-01 <br />The required sewer wastewater demand are currently available from MHCSD's System, and <br />the District has the ability to assign the required sewer capacity to the subject property since this <br />development is a job-creating proposed use.
