CVWRF Water Reuse Study

The purpose of this study was to evaluate the potential market for the use of wastewater treated effluent from the Central Valley Water Reclamation Facility (CVWRF) for irrigation and other uses. The study identified potential reclaimed water users, the associated potential reclaimed water demand, potential transmission pipeline sizes and alignments, required additional treatment, storage, pumping facilities, and the associated costs for such a project. The cost evaluation included construction costs as well as operation and maintenance costs. The document is intended to assist CVWRF and its member entities in evaluating the potential expansion of the CVWRF wastewater effluent reuse system.

The potential reuse demands within the CVWRF service area were estimated by identifying large outdoor water users. This was accomplished with assistance from the water purveyors within the study area as well as visually identifying large irrigated parcels on aerial photography. The water use demands for these parcels were estimated through consideration of several factors including the amount of water consumed by the plants, the weather, and the efficiency of the irrigation systems.
