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.
Since 1997, the Water Authority has followed a formal master planning process, leading to the 2003 Regional Water Facilities Master Plan and the 2013 Regional Water Facilities Optimization and Master Plan Update.
The latest update, the 2024 Water Facilities Master Plan, builds on this foundation with a comprehensive evaluation to develop strategies that address the region’s water infrastructure needs through 2045, considering future supply, demand conditions and uncertainties. Set to be reviewed by the Board in early 2025, the 2024 plan focuses on optimizing both current and future system improvements to meet future needs, reduce costs, and enhance overall efficiency.
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.
