The Plan

The Metropolitan Water District of Southern California prepares for tomorrow through an evolving long-term water strategy known as its Integrated Water Resources Plan, or IRP. The inaugural IRP was adopted in 1996 to address the complexity of developing, maintaining and delivering water to meet changing demands in the face of growing challenge. The plan has been updated several times over the past 25 years. In 2020 we are starting afresh with a new IRP that will incorporate different scenarios for the future. The IRP is a regional example of the long-term, diversified strategy Gov. Newsom is seeking statewide through his Water Resilience Portfolio Initiative.

Water Resilience Portfolio

“Metropolitan has seen first-hand the successes that come with long-term planning and diversified water supply portfolio.  In fact, Metropolitan was among the first water agencies to take this approach when we initiated our Integrated Resources Plan two and a half decades ago."

-Metropolitan Board Chairwoman Gloria Gray

2015 IRP Goals

MAINTAIN COLORADO RIVER  AQUEDUCT SUPPLIES

Develop programs to ensure that a minimum of 900,000 acre-feet is available when needed, with access to 1.2 million acre-feet in dry years.

ACHIEVE ADDITIONAL CONSERVATION SAVINGS

Pursue further water conservation savings of 485,000 acre-feet  annually by 2040 through  increased emphasis on outdoor water-use efficiency using  incentives, outreach/education and other programs.

DEVELOP ADDITIONAL  LOCAL WATER SUPPLIES

Develop 230,000 acre-feet of additional local supplies produced by existing and future projects. The region would reach a target of 2.4 million acre-feet by 2040, a key to providing water supply reliability into the future.

STABILIZE STATE WATER PROJECT SUPPLIES

Manage SWP supplies in compliance with regulatory restrictions in the near-term for an average of 980,000 acre-feet of SWP supplies. Pursue a successful outcome in the Delta Conveyance Plan and California EcoRestore efforts for long-term average supplies of about 1.2 million acre-feet.

MAXIMIZE THE EFFECTIVENESS OF STORAGE AND TRANSFER

Develop a comprehensive strategy  to pursue transfers and exchanges to hedge against shorter-term water demands and supplies imbalances  until long-term solutions are in place.

ENCOURAGE INNOVATION

Facilitate innovation in recycled water, desalination, stormwater capture and groundwater cleanup through a growing portfolio of initiatives, technologies and new ideas.
