Crews will begin tearing up Agoura Road in Westlake Village on Monday, Oct. 5. The pipeline work will bring four to six months of lane closures, turn restrictions and traffic delays between Lindero Canyon Road and Lakeview Canyon Road.

The construction is part of the Pure Water Project, a regional effort by the Las Virgenes–Triunfo Joint Powers Authority (JPA) to build an advanced water recycling system. The JPA is a partnership between Las Virgenes Municipal Water District (LVMWD) and Triunfo Water & Sanitation District.

Starting Oct. 5, crews will excavate roadway, remove asphalt, install pipeline and place underground equipment along Agoura Road, according to the city's project page. The work will run during both daytime and nighttime hours.

Motorists should expect temporary lane closures, lane shifts, turn restrictions and delays within the active work zone. Pedestrians and cyclists will also encounter traffic-control measures.

The system will take surplus recycled water from the Tapia Water Reclamation Facility and purify it through membrane filtration, reverse osmosis and ultraviolet light with advanced oxidation. The purified water is then blended with imported water at the Westlake Filtration Plant before entering the drinking water system.

When complete, the project will supply up to 30% of the area's drinking water. LVMWD currently relies entirely on imported water, according to a Thousand Oaks project summary.

The overall project, which includes a new Advanced Water Purification Facility (AWPF) on Agoura Road in Agoura Hills, began construction in March 2026 and is expected to wrap up in fall 2028. Walsh Construction signed the contract on Feb. 11, 2026, according to an LVMWD board agenda.

Preliminary potholing along the Agoura Road corridor was completed Friday, Sept. 4. The segment then entered a pause before this next phase.

At a July 8 Westlake Village City Council study session, LVMWD Engineering Program Manager Oliver Slosser said project refinements had shortened the planned westbound Agoura Road closure from four months to roughly six weeks. By combining the Pure Water pipeline and aging water-line replacement, LVMWD expected to cut total construction impacts from 10 to 11 months down to about five months, according to council minutes.

Local businesses have raised concerns. Westlake Village Inn CEO Chris Culty told the council at the same July 8 session that closing westbound Agoura Road would hurt customer access, deliveries and operations. Culty supported additional night work if it could shorten the closure.

Jan Russell, owner of the Village Chevron at 31505 Agoura Road, warned in a written comment to the council that previous construction in the area had cut her business volume to about a quarter of normal levels.

LVMWD General Manager Dave Pedersen acknowledged the concerns at the July 8 session and committed to continued collaboration with the city and stakeholders.

At the project's 2025 groundbreaking, LVMWD Vice President Jay Lewitt framed the long-term promise: "The water that was once lost to the ocean will come back to us, full circle, giving us a reliable source of water."
