SECTION IV <br />PROJECT ALTERNATIVES <br />Alternative Descriptions and Conceptual Designs <br />In 2008 the Snowmass Water and Sanitation District purchased Ziegier Reservoir with <br />the intention of enlarging the reservoir and connecting the reservoir to an existing raw <br />water delivery system located approximately 1,400' from the reservoir. <br />Several alternatives were considered. <br />- Alternative 9- No Immediate Action - Delay construction of pump house, Divide <br />Flow Contro/ Building and installation of water line until expansion of the <br />reservorr. <br />This alternative was rejected. Until a pump station is constructed the reservoir is <br />of no benefit to the District. <br />- Alternative 2- Make use of the existing reservoir prior to expansion of the <br />reservoir - Instal/ portable Gensets and temporary pump sfation and construct <br />fhe Divide F/ow Contro/ Building. <br />This alternative was rejected and conceptual designs were not considered. <br />The existing reservoir is currently supplied by an 8" ductile/cast iron supply line <br />but doesn't have any electric power or pump station at the reservoir to pump <br />water to the Districts raw water delivery system. Expending money on pumps, <br />gensets and constructing a temporary pump house, all of which wouldn't be <br />usable as part of the Ziegler Reservoir expansion, was an impractical and <br />wastefu~ approach. fn addition, the construction of above ground temporary <br />facilities would be prohibited by the reservoir purchase agreement and Pitkin <br />County Land Use approvals. <br />1 Alternative 3- Make use of the existing reservoir prior to expansion of the <br />reservoir- Instal/ a pump house, provide a new electric service and telemetry, <br />install a new 16" HDPE supply line and construct a Divide Flow Control Building. <br />This alternative was selected as this project is a point-to-point connection of the <br />Districts existing raw water delivery system located at the Divide Flow Control <br />Building to the new Ziegler pump house adjacent to the reservoir. The reservoir <br />is approximately 1,400' from the Divide Flow Control Building and the connecting <br />water line can only be installed in the available easement. <br />5 <br />
