Water Supply Planning and Water Rights
Woodland-Davis Clean Water Agency, California

In the early phases on the Davis Woodland Water Supply Project, the timeliness for pursuing the existing area-of-origin water right was critical. West Yost assisted in driving the application through the process, including testifying at the hearing to the State Water Resources Control Board. After this water right was secured, additional water was still needed in key summer months to address shortages due to Term 91 conditions.

To address the need for these additional seasonal needs, West Yost successfully negotiated with Conaway Preservation Group for an additional 10,000 acre-feet of water yearly, and is currently pursuing an Aquifer Storage and Recovery program with the Agency to further assist in meeting water demands under “severe” conditions. West Yost developed a Supply Deficit Probability Model to provide analysis on when additional supplies were needed and to evaluate how each additional source contributed to the reliability of the project.

West Yost is currently assisting the Woodland-Davis Clean Water Agency in an Owner’s Representative capacity for the program and Design-Build-Operate procurement contract management, water rights acquisition, public outreach, environmental permitting and preliminary design of a new regional surface water supply project. The project will consist of a diversion intake facility on the Sacramento River, a conveyance pipeline from the intake to a new 56 mgd capacity water treatment plant, and a pipeline distribution system to the participants’ service areas. Construction on the new facilities was completed in 2016.
