3. Alternative Sites This alternative ties into the MWC distribution system at the same locations with the same diameter water main (4"). The alignment deviates from that in Alternate 2 near the intersection of CR 16 and CR M. The water line will follow the County Road in rocky terrain instead of crossing behind a home in the area through tilled dryland. The rest of the water line alignment remains the same. The tank would be located at the end of the proposed water line along CR M where it meets private property. The pump station would still be located near the intersection of CR P and CR 17 to provide sufficient lift to transport water to the storage tank. Figure V -2 shows the locations of the alternative tank and pump locations, as well as the alternate water line alignment as described above. The highest service elevation is located near the end of County Road M, adjacent to the water storage tank. In order to serve the highest elevations within the service area, a conventional water tank that can flow by gravity and generate sufficient pressures to the high areas would have to be an elevated tank approximately ninety-five feet (95') high if located at the highest elevation within the distribution system. Consideration of the size and height of an elevated tank as well as the visual impacts on neighboring public lands was reviewed for this option. Since the tank must be at an approximate height of ninety- five feet (95') and the available tank from MWC is only twenty feet (20') tall, the possibility of using this tank for the project is eliminated for this alternative. An equivalent number of residences would require a PRV for this alternative as is required for the proposed action alternative. B. Design Criteria Design criteria used for evaluation of the proposed project and alternative sites meet the requirements as defined in RUS design policies, as well as any applicable state design requirements. Design criteria used to evaluate the proposed project and alternative sites include the following: .,/ Minimization of environmental impacts. .,/ Provide energy efficient and environmentally sound products. .,/ Ensure sufficient capacity to provide reasonable fire protection. .,/ Provide sufficient capacity for growth. .,/ Meet current American Society for Testing Materials (ASTM) and American Water Works Association (A WW A) standard for all pipe used. .,/ Leakage testing in the water system will not exceed limits set by either ASTM or AWWA. .,/ Provide metering devices for each service connection. Additional applicable state design criteria used in evaluating the proposed project and alternative sites include: Goodman Point Water Association - Preliminaty Engineering RepOli 12
