Ventura is one of the largest cities in Southern California to rely solely on local water supplies. Rainfall feeds the Ventura River, Lake Casitas and groundwater basins to meet all community needs. But prolonged drought, increased regulations, and operational and legal challenges have impacted Ventura’s local water supply.
Should drought conditions continue, Ventura’s water demand could outpace its supplies by 2035.
A decade of comprehensive evaluations, studies, and piloting have allowed local leaders to considered many forward-thinking solutions to Ventura’s water problem. Ultimately, this work led to the VenturaWaterPure Program.
VenturaWaterPure will recover, treat and reuse water that is currently discharged into the Santa Clara River Estuary, creating a locally-owned, drought-resilient water source that isn’t dependent on rainfall.
STEP 1. Currently, wastewater from the City of Ventura is sent to the Ventura Water Reclamation Facility where it’s treated and cleaned before being discharged into the Santa Clara River Estuary. This water will be sent to a new Advanced Water Purification Facility (AWPF) for reuse.
STEP 2. Using a scientifically proven process, the AWPF will treat water to drinking-water standards, creating a reliable and high-quality water source.
STEP 3. The purified water will then be injected into a local groundwater basin and later distributed to Ventura Water customers.
VenturaWaterPure will use a five-stage treatment process that produces purified water that exceeds drinking water quality standards.
Reverse Osmosis (RO)
Ultraviolet Light/ Advanced Oxidation (UV/AO)
This proven approach is used throughout California, the U.S. and internationally.
The City operated a demonstration facility that achieved water quality standards, conforming with the State Division of Drinking Water’s strict regulations under Title 22 of the CA Regulations for Indirect Potable Reuse.
Additionally, EPA’s Reuse Action Plan recognizes the City of Ventura’s success in “maintaining transparency” and outreach to the community through the treatment process demonstration.
