CMP Part 4C. Water Supply <br /> WATER SYSTEM EVALUATION <br /> General <br /> This section provides an evaluation summary of the existing water supply, treatment, <br /> storage, and distribution systems for the City of Orono. The existing system consists of <br /> four water supply systems. These four systems consist of four supply wells, two elevated <br /> storage tanks, two water treatment facilities, and four distribution systems. The existing <br /> water infrastructure components have been evaluated in terms of current and future <br /> demands. <br /> Water Supply Wells <br /> GeneFal <br /> The City of Orono currently obtains water from four wells, Navarre Well 1 and 2 <br /> Well Capacity <br /> The Recommended Standards for Water Works(Ten State Standards)recommends <br /> that the average day demand be met by the firm capacity. Firm capacity is the <br /> pumping capacity with the largest well out of service. In addition, the daily well <br /> output is calculated based on operating for 20 hours per day to allow 4 hours per <br /> day of aquifer recharge. Using these standards, the Navarre Water System has a <br /> total capacity of 1.80 MGD and a firm capacity of 0.60 MGD. The Highway 12 <br /> Water System has a total capacity of 1.60 MGD and a firm capacity of 0.6 MGD. <br /> Table 4C-1 earlier in this chapter summarizes well capacity. <br /> Table 4C-7 and Table 4C-8 present the number of wells that will be needed to meet <br /> future demand projections for the Navarre and Highway 12 systems. The projected <br /> . , .. - . . . . . - - . : <br /> 8. As shown in Table A1C 7, nNo additional wells are required for either system as <br /> both have adequate well capacity to meet future demands.— <br /> City of Orono Community Management Plan 2020-2040 Part 4C, Page 9 <br />
