Water Tomorrow

Metropolitan is in the process of updating its integrated resources plan.  The plan establishes water resource goals to help meet the region’s water supply needs over the next several decades.  These goals will guide policy discussions and investment decisions for imported and local water supplies as well as demand management through conservation.  The Board of Directors will consider policy issues at the Integrated Resources Plan Committee.  The committee meetings are open to the public.

Staff and member agencies are currently working on technical analysis of the following:

• Retail demand

• Water use efficiency

• Local supplies – groundwater, surface water, storm water, recycled water,
  seawater desalination

• Imported supplies

• Long-term uncertainty

Examples of Local Projects and New Technologies

Well heads like the North Las Posas well head in Calleguas MWD are used to inject water into the ground for future storage in the conjunctive use program.

Advanced membrane technology like these reverse osmosis filters are used to treat wastewater for beneficial use, resulting in near-distilled quality water at the Orange County Water District’s Groundwater Replenishment System.

Rio Honda
Spreading Basins like the Rio Hondo desilting pond in Central Basin MWD are used to replenish our groundwater basins.
