Northeast Area. The long-term northeast wastewater service area has the potential to generate <br /> wastewater flows that slightly exceed the capacity of the interceptors serving this area. Rather <br /> than constructing an extensive capacity relief interceptor system, a potentially feasible <br /> alternative is to construct a wastewater reclamation plant with groundwater recharge and <br /> wastewater reuse. <br /> Hastings. A new Hastings Plant is planned to replace the existing plant located near downtown. <br /> The new plant will be expandable, with a long-term service area that includes portions of <br /> Marshan, Nininger, and Vermillion townships. The plant site has been acquired. <br /> Table 3 summarizes the planned capacity of the regional wastewater treatment plants. <br /> Table 3.

Wastewater <br /> flow projections are based on 60 gallons per day (gpd) per person and 15 gpd per employee <br /> from new development, and gradual reduction of wastewater flow from existing development, <br /> which reflects water conservation and reduction of inflow and infiltration. <br /> 36 <br />
