This project replaces the existing, leak-prone and fire-vulnerable roof at the District’s San Geronimo Treatment Plant. The new roof at the San Geronimo Treatment Plant will be more durable, as well as fire resistant, contributing to improved fire hardening of the treatment plant.
Construction Update (September 2026)
