‘One Water’ Awards ceremony shines a spotlight on Southern California’s leaders in conservation, commitment to finding solutions

Six businesses and municipalities throughout Southern California were recognized by the Metropolitan Water District today for their investments in large-scale water-efficiency projects that together will save more than 1 billion gallons of water over the next decade.

Metropolitan’s One Water Awards ceremony at the California Endowment in downtown Los Angeles honored organizations that used funding from Metropolitan’s Water Savings Incentive Program to make major improvements to their water management operations and equipment, such as installing smart irrigation technology, water recirculation systems and soil moisture sensors.

“The transformation of daily operations for these organizations translates into long-term, sustainable change for entire communities,” said Metropolitan General Manager Adel Hagekhalil. “Today’s ceremony demonstrated that when everyone does what they can to use less water, we produce real water savings that benefits millions.”

The following projects were presented with One Water Awards (click on links below for short videos on each project):

“Drought and climate change have stressed water supplies across the western United States and require us to think differently about how we plan and manage our water,” said Metropolitan Board Vice Chair for Climate Action Heather Repenning. “The projects being recognized today showcase innovation and adaptation. These are the kinds of solutions we need to ensure a climate-resilient water supply for our region.”

Named for Metropolitan’s approach to water management that values and acknowledges that all water resources are connected, the One Water Awards program amplifies the success of participants in its Water Savings Incentives Program. The program provides funding to commercial, industrial, institutional and agricultural customers that make water efficiency upgrades to their facilities but may not qualify for Metropolitan’s standard commercial rebate programs. It pays up to $0.60 per 1,000 gallons of water saved annually through customized projects that are developed by each organization to fit its needs.


Since 1990, Metropolitan has invested nearly $1 billion in conservation programs, saving about 3.5 million acre-feet of water. An acre-foot is about 326,000 gallons, enough to serve three typical Southern California households for a year.
