A Multi Process Approach With One Single Solution

A joint effort between the city of Hollister, the San Benito County Water District and the Sunny slope County Water District, the group proposed the West Hills Water Treatment Plant (WHWTP) project to improve drinking water quality, water supply reliability, and to balance regional water resources in the Hollister Urban Area (HUA). Historically, HUA relied primarily on local groundwater basins for meeting their drinking water demands. While groundwater met all drinking water regulations, it is high in minerals and hardness that often resulted in scaling and the need for further conditioning. Along with other initiatives, the WHWTP project enables the District to meet these goals through increased surface water capacity from the San Luis and San Justo Reservoirs.
