Integrated Regional Water Management (IRWM) is a collaborative effort aimed at developing long-term water supply reliability, improving water quality, and protecting natural resources. The Statewide IRWM Program is supported by bond funding provided by the California Department of Water Resources (DWR) to fund competitive grants for projects that improve water resources management.

The San Diego IRWM Program began in 2005 as an interdisciplinary effort by water retailers, wastewater agencies, stormwater and flood managers, watershed groups, the business community, tribes, agriculture, and non-profit stakeholders to improve water resources planning in the San Diego IRWM Region. The program has achieved remarkable success! In 2007, San Diego published its first IRWM Plan and received $25 million from DWR to support 18 high-priority water management projects. In 2011, San Diego obtained another $8 million to support 11 more important projects and $1 million to fund a comprehensive update of the 2007 IRWM Plan. In 2013 and 2014, respectively, $10 million was awarded to support an additional 7 high-priority projects, and $15.1 million awarded for drought relief projects. The region was awarded almost $31 million for 13 high priority projects in 2015. The region received $5.5 million for Disadvantaged Communities Involvement planning projects and $15.3 million in 2020 for 7 priority implementation projects. In 2022, the Funding Area received $5 million for 4 drought projects in underrepresented community areas and $16 million for 6 priority implementation projects. In total, the Region has received approximately $132 million, which has funded 84 priority projects including the 2013 and 2019 IRWM Plan updates.

The San Diego Region recently updated the 2013 San Diego IRWM Plan to comply with DWR's 2016 IRWM Program Guidelines, incorporate new water planning studies, and make the Region eligible for future rounds of grant funding. The 2019 IRWM Plan has allowed regional stakeholders to revisit the Plan goals, objectives and priorities in light of changes that have occurred since 2013. Like the 2013 IRWM Plan, the 2019 IRWM Plan provides a mechanism for: 1) coordinating, refining and integrating existing planning efforts within a comprehensive, regional context; 2) identifying specific regional and watershed-based priorities for implementation projects; and 3) providing funding support for the plans, programs, projects and priorities of existing agencies and stakeholders.
