Project: Proposition 1 Round 1 East Stanislaus IRWM Grant

Description: East Stanislaus IRWM

Reference Number: 3860-P01-383

Implemented By: Stanislaus Regional Water Authority

Objective: The East Stanislaus Region is proposing one project for grant funding. This project is in support of the Stanislaus Regional Water Authority Water (SRWA) Regional Surface Water Supply Project (RSWSP). The RSWSP will provide a new surface water supply source to Ceres and Turlock, greatly improving regional water supply reliability to ensure the cities meet current and future water demands. Currently, both cities rely solely on Turlock Subbasin groundwater to meet all water needs. The groundwater basin has several water quality concerns related to contamination, such as nitrates, arsenic, and 1,2,3-trichloropropane. Water treated by the new WTP will meet, or exceed, state and federal drinking water quality requirements and will not contain the above mentioned contaminants. The project benefits the Cities of Ceres and Turlock by providing local surface water that, in combination with the cities’ existing groundwater systems, will create conjunctive-use opportunities. Conjunctive use allows for use of surface water as a base supply and groundwater to meet peak demands. The result will be a natural recharge of the groundwater basin. City of Turlock, City of Ceres, and Turlock Irrigation District have been collaborating for 20 years to develop a project that addresses the water quality and supply issues the two cities are facing while decreasing riparian impacts from TID’s water diversions. This collaboration resulted in the formation of the Stanislaus Regional Water Authority JPA in 2011. The cities realized cost and operational efficiencies by joining their efforts in constructing a water treatment plant and will jointly utilize TID’s water rights. The project brings TID the benefit of having more flexibility in how it supplies raw water to its irrigation customers. As a result of discharging more water from La Grange Dam, the increased flows in the upper Tuolumne River decrease the River temperature and provide a better environment for aquatic species.
