Wayhill Tanks Replacement (Project)

The Wayhill Tanks Replacement Project, overseen by the State Water Resources Control Board Division of Drinking Water, involves the removal and replacement of two existing 500,000-gallon concrete reservoirs at the Golden State Water Company's Wayhill facility located at 440 W. Gladstone Ave., San Dimas, California. The project replaces the existing infrastructure with two new welded-steel reservoirs of the same capacity in the same location. The new tanks will be 30 feet tall with an overflow set at 27 feet, providing 3 feet of freeboard to comply with current seismic standards for slosh-wave requirements. Additionally, the new reservoirs will be lettered with the city name to match the existing tanks. The project is categorized as a forecast under NAICS code 237990 and was issued a design approval and Notice of Exemption on August 18, 2025. It is categorically exempt under Class 2 of the California Code of Regulations section 15302 because it replaces existing infrastructure without expanding capacity or location, ensuring compliance with CEQA guidelines. Administrative oversight is provided by District Engineer Dmitriy Ginzburg of the Division of Drinking Water in Glendale, California, with George Zakhari serving as the administrative contact for the Golden State Water Company.
