West Yost recently prepared a draft Recycled Water Feasibility Study for the City of Rialto and the State Water Resources Control Board that explored the possibility of adding a new scalping plant and a recycled water distribution system to serve recycled water to the central portion of the City. The service area for the proposed scalping plant is shown below in the area marked by the red box. The map also includes the site for the proposed plant.

The capital costs include capital construction costs for a new 0.841 million gallons per day scalping plant, 3.6 million gallon storage tank, recycled water fill station, recycled water distribution pipelines, and ongoing operation and maintenance costs for the scalping plant and proposed pipelines.
