areas can be served by the regional wastewater system. However, redevelopment of areas in <br /> closer proximity to transit and major highways within the Metropolitan Plant's service area has <br /> lower cost and much higher potential for wastewater generation that will utilize the plant and <br /> interceptor system's long-term capacity. Consequently, the above study areas have been <br /> omitted from the long-term wastewater service area to reserve capacity for those areas that are <br /> redeveloping. <br /> Eastern Hugo, which has previously been identified as a study area for potential future <br /> wastewater services, has also been omitted from the long-term wastewater service area. <br /> Studies are under way to determine the relationships among groundwater withdrawal for <br /> municipal water supply, groundwater recharge, and lake levels and then to develop a water <br /> sustainability plan for the northeast part of the region. <br /> St. Croix Valley. Previously, the wastewater system plan assumed a future plant expansion. <br /> The current regulatory trends indicate the likelihood of much more stringent future discharge <br /> permit limits. The additional facilities to meet these limits are likely to fully utilize the remaining <br /> capacity at this plant site. Consequently, no plant expansion is planned. A modest service area <br /> increase of approximately 1,000 acres should be adequate to utilize the remaining capacity. <br /> Given their proximity to Hwys. 36 and 5 and to adjacent sewered development, portions of <br /> Baytown and Grant are most viable potential long-term service area additions to the existing <br /> service area. <br /> Potential Future Wastewater Treatment Plants <br /> To support long-term sewered development of the region, five new wastewater treatment plants <br /> are envisioned in the northwest, northeast, southeast, and southwest areas. These areas also <br /> face water supply challenges due to the absence of the Prairie du Chien Jordan aquifer or <br /> demand that may cause excessive aquifer drawdown. Consequently, new wastewater <br /> treatment plants are proposed to be wastewater reclamation plants that produce treated water <br /> that is suitable for non-potable uses, such as toilet flushing and irrigation, which will reduce the <br /> water demand on the groundwater aquifers. In the northeast area, groundwater recharge with <br /> treated wastewater also appears feasible. <br /> Crow River. The Council and the City of Rogers have been working to locate a new wastewater <br /> reclamation plant in western Rogers. This plant will eventually serve Rogers, eastern Corcoran, <br /> and western Dayton, and provide long-term capacity relief for the Elm Creek Interceptor. <br /> Carver County. The potential wastewater generation for the long-term service area of the Blue <br /> Lake Plant could exceed the build-out capacity of the plant site sometime after 2040. One option <br /> to address this possibility is a service area revision that diverts wastewater from western <br /> communities to a new regional wastewater reclamation plant in Carver County. This new plant <br /> should be located so that it could serve development along the corridor between Chaska and <br /> Cologne. <br /> Scott County. The Scott County 2030 comprehensive plan, prepared in coordination with the <br /> regional wastewater system plan, designates portions of western Scott County for potential <br /> long-term sewered development. This area will be served by a future regional wastewater <br /> reclamation plant located in the Louisville Township area. This plant also could provide capacity <br /> relief for the Blue Lake Plant. <br /> 35 <br />
