In 2001, the Contra Costa Water District (District) created a new programmatic process to improve the District's steel water tanks after inspections identified significant corrosion and structural degradation in a number of tanks. The approach for implementation of this program has been to assess the long-term, overall condition and operational effectiveness of the tanks on a case-by-case basis but under an overall global view of the twelve steel tanks as a whole, with improvements prioritized based on the lowest life cycle cost-to-benefit required to bring these facilities to current industry standards.
