Water Authority Builds Infrastructure to Meet Region’s Water Demands

The Water Authority has executed an ambitious plan since 1989 to design and build world-class public works projects to help reduce its dependence on imported water and enhance its water delivery system. This plan, known as the Capital Improvement Program (CIP), remains focused on meeting water demands within the region.

The 2003 Regional Water Facilities Master Plan identified additional projects and facilities that need to be included in the CIP to ensure the Water Authority could achieve its mission of providing a safe and reliable water supply to the San Diego region. Many of these facilities have since been constructed.

In 2013, the Water Authority finalized the Regional Water Facilities Optimization and Master Plan Update, the agency’s new roadmap for infrastructure investments through 2035. This updated plan focuses on optimizing the Water Authority’s existing infrastructure while maintaining the flexibility to adjust to a range of future water supply needs. 

The Water Authority strives to be a good neighbor to local residents and businesses residing near its current and future facilities by providing up-to-date information to and working with the communities that are affected by construction projects.

Collaborating with the Business Community

The Water Authority also reaches out to the business community to solicit competitive proposals and bids for its construction projects. If your company would like more information about contracting with the Water Authority, or would like to view additional documents including design manuals or the General Conditions and Standard Specifications, go to the Water Authority’s Contracting Opportunities web page.
