ACCELERATED DROUGHT RESPONSE PROJECT
The Accelerated Drought Response Project (ADRoP) is a water storage project that will improve drought resilience for the existing County residents.
It will allow the San Benito CountyWater District (District) to store excess wet-year water in the local groundwater basin and recover those supplies during future droughts. ADRoP will include an expansion of the West Hills Water Treatment Plant, the construction of up to 5 aquifer storage and recovery wells (ASR Wells), and associated water transmission pipelines. The project is estimated to cost approximately $55 million. However, the District has secured $20 million in grant funding from the State and Federal governments, which will help limit rate impacts. The District continues to work on securing additional funding to further minimize rate impacts.
Water Supply Reliability
Helps meet drought demands.
Mitigates for reduced availability
of imported water in dry years
Improves Water Quality
Maintains high water quality
during droughts.
Local Control
Reduces reliance on state-
wide water delivery system.
Construction Schedule
West Hills Water Treatment Plant Expansion
ASR Wells
Pipelines
Project Cost
The current construction cost estimate is $55 million. State and Federal grants will cover more than one third of project costs.
- California Department of Water Resources: $13.7 million
- U.S. Bureau of Reclamation: $6.7 million
Construction Impacts
West Hills Water Treatment Plant Expansion
Impacts will be minimal and will be limited to an insignificant increase in traffic on Union Road.
ASR Wells
Impacts will be minimal due to location in agricultural areas but has the potential to increase noise levels.
Pipelines
Moderate traffic impacts could result along San Felipe and Fallon Roads, potentially with one-way traffic controls.
