I I I I I I I I I I I I I I I I I I I was considered for this Planning Document. Alternate G: Storage at lake Estes and Transmission to an Upgraded Water Treatment Plant This altemate would involve a 50 gpm pumping facility to convey water stored in Lake Estes on the east side of the City of Estes Park to an expanded water treatment plant, as described in A1temate A. The transmission pipeline would parallel Colorado Highway 36 for much of its length. A possible altemative (which would eliminate some of the transmission pipeline costs) would be to pipe water from Lake Estes into the Little Thompson drainage, provided that resulting water losses from the streambed and evaporation would be acceptable. Alternate H: Storage at Pinewood lake and Transmission to an Upgraded Water Treatment Plant This altemate would involve a 50 gpm pumping facility to convey water stored in Pinewood Lake located in Section 31 of Township 5N, Range 70W to the expanded water treatment plant, as described in Altemate A. Alternate I: Hauling Treated Water from Off-5ite Sources for Introduction Into the Pinewood Springs Distribution System This altemate is essentially the status quo altemate which must be considered. Pinewood Springs will need to continue hauling water in from off-site during dry years if no other action is taken. Despite significant conservation efforts and low per-capita water usage, it will not be possible for the District to avoid water hauling without additional storage. Power and Standby Power Alternatives for standby power were considered in preparing this Planning Document. There is no 3-phase power supply loop to the project area available from Poudre Valley REA at present. Therefore, standby power to increase reliability for the altemates evaluated will have to be provided by either an on-site generator, rented mobile generators, or by extending an altemate power supply loop to the area. 5
