LCWA Watermain Lining Project

The State Water Resources Control Board is funding the LCWA Watermain Lining Project to rehabilitate approximately 4,000 linear feet of 18-inch diameter watermain using cured-in-place pipe (CIPP) technology, allowing for in-place renewal without full replacement. The project requires the excavation of nine access pits along the watermain route, each measuring about seven feet by twelve feet, with surrounding work areas spanning roughly 20 feet by 50 feet per site. Following installation, all pits will be backfilled, hydroseeded, and restored to match pre-construction ground contours as closely as possible to minimize long-term environmental and aesthetic impact. The project is located in Seal Beach, California, and is identified internally under Project Number 3010041-001C. The project was posted as a forecast on May 28, 2026, and is managed by the California State Water Board’s Division of Financial Assistance. Primary points of contact include Abbygayle Guevara, Environmental Scientist at the State Water Board, and Iris Lee, Public Works Director for the City of Seal Beach. While no solicitation number or NAICS code has been assigned, the project remains under the oversight of state environmental and public works authorities to ensure compliance with water infrastructure standards and local restoration requirements. The work aims to enhance water system integrity while reducing disruption through minimally invasive rehabilitation techniques.
