Siting of a Reclaimed Water Reservoir

The City of Santa Rosa (City), California, retained Woodward-Clyde Consultants to identify, evaluate, screen and rank potential sites for construction of a dam and reservoir to store reclaimed water. By use of a unique screening process for ranking and rating the sites, four alternative 'apparent-best' storage sites were selected for further evaluation. Woodward-Clyde Consultants developed preliminary dam design and construction cost data for these sites for review by the City. This paper will present an overview of the screening process used in the site selection evaluations, and a summary of the feasibility-level designs and construction cost estimates.
