VALENCIA WELL PROJECT at CALLEGUAS CREEK PARK
Camrosa Water District (Camrosa) was established in 1962 as an independent special district. Camrosa provides water and wastewater services to a population of approximately 35,000 residents across a 31-square mile service area of Ventura County. Retail water services extend to unincorporated areas of Ventura County and portions of the cities of Camarillo, Moorpark, and Thousand Oaks. Customers include residential, commercial, agricultural, and light industrial users. Camrosa manages three distinct water distribution systems: Potable water; non-potable water; and, recycled water, as well as a wastewater collection and treatment system.

PROJECT PURPOSE
Many factors such as climate cycles, increased regulations, population growth, and urbanization are expected to continue increasing the stress on traditional water sources. State Water Project (SWP) deliveries significantly decreased during recent drought restrictions by the State, underscoring the need to diversify water supply sources. This was reflected in Camrosa ’s 2022 Strategic Plan, which identified water supply independence as a primary objective. This independence would be achieved through developing additional local resources and reducing the amount of expensive imported water purchased. As part of the water supply independence objective, Camrosa has explored many options in order to diversify and boost water supplies.
PARTNERING WITH PLEASANT VALLEY RECREATON & PARK DISTRICT
Mutually beneficial partnerships build relationships that bring additional water resources under the Camrosa umbrella and enhance Camrosa’s ability to become more self-reliant while helping our neighbors. When Camrosa partners with the Pleasant Valley Recreation & Park District (PVRPD), that partnership helps provide the community with a reliable, sustainable source of water while reducing park costs through sharing that resource for park irrigation.

Lynnwood Well
In 1981, Camrosa first partnered with PVRPD to develop the first Camrosa well (Woodcreek Well) in the Pleasant Valley Groundwater Basin (PVB) in Woodcreek Park and then once again in 2015 to develop an additional well at that location (Lynnwood Well). In order to continue to develop additional water resources for the community, Camrosa worked with PVRPD and performed several investigational studies to locate and evaluate potential sites that could be suitable for constructing additional wells. Camrosa focused on locations within the PVB because, since 2014, Camrosa has been accruing groundwater credits for future extraction through the Conejo Creek Project (CCP). The CCP is a partnership with the City of Thousand Oaks that brings non-potable water into the PVB to reduce pumping demands from agricultural users.
Additional well siting studies narrowed the locations to two optimal locations, Heritage Park and Calleguas Creek Park, and an agreement was reached for two monitoring wells. In the fall of 2024, Camrosa completed the drilling and testing of the well in Heritage Park. Initial results indicated that the site would not be favorable for a production well. Camrosa will continue to use the well for groundwater quality and basin sustainability monitoring.
PROJECT PROGRESS
The agreement to develop the two monitoring wells contained a provision that “… at such a time that Camrosa desires to construct a new production well at one of the two sites, the parties intend to negotiate a separate agreement…” Camrosa and PVRPD have reached agreement on the terms for the agreement for the Valencia Well Project at Calleguas Creek Park.

Calleguas Creek Park
In early 2025, Camrosa engaged MNS Engineers, Inc. (MNS) to perform preliminary design for a Calleguas Creek Park production well. As part of this preliminary design, potential well sites within the park were explored with PVRPD and Camrosa staff. In September 2025, MNS delivered the Valencia Well and Treatment Facility – Final Preliminary Design Report. The report focused on providing alternative facility designs to address options for on-site treatment or conveying the well water to the existing treatment facilities located within the Lynnwood Well facilities. In order to minimize the square footage of the well facilities at the park, Camrosa recommended the conveyance option with the reduced site plan.
With PVRPD’s selection of their preferred location and approval of the Lease Agreement, Camrosa will be able to move forward with the well development process. The well drilling and testing is anticipated to begin Summer 2026 and take 60-90 days. Should the well testing indicate sufficient production can be achieved, final design for the park well facilities and conveyance will follow and take about 12 months. Facilities and conveyance construction is anticipated to take an additional 8-10 months.
MOVING FORWARD
Camrosa is excited to continue advancing the Valencia Well Project at Calleguas Creek Park in partnership with PVRPD. By developing this additional local water supply, Camrosa will further reduce its reliance on imported water, improve long-term water supply reliability, and strengthen its commitment to sustainability for the community it serves. This project represents another step toward achieving the goal of water supply independence while supporting regional collaboration and shared community benefits.
