LOS ANGELES (August 23, 2018) – Los Angeles Mayor Eric Garcetti was joined by Los Angeles Department of Water and Power General Manager David H. Wright, Board of Water and Power Commissioner Christina Noonan and representatives from the Metropolitan Water District of Southern California (Metropolitan), to recognize Cedars-Sinai Medical Center’s efforts to reuse groundwater as part of its operations, saving up to 29 million gallons of drinking water annually. Officials congratulated the L.A. medical center’s leaders for their commitment to sustainability and water conservation, and encouraged other L.A. businesses to implement similar groundwater recycling projects.

“Los Angeles is changing how we think about water, by rewarding those who conserve,” said Mayor Garcetti. “At a moment when climate change and drought are becoming the new normal, the Cedars-Sinai treatment facility shows how property owners can help us better withstand the effects — through a strong commitment to conservation and sustainable design.”

Groundwater runs under portions of the city, including the area in West LA where the Cedars Sinai Medical Center campus sits. In areas where groundwater is present, it must be diverted in order to maintain the structural safety of the buildings above it. Cedars-Sinai installed a recycling system to reuse the groundwater instead of discharging it to the sewer. The system now provides 50-80 percent of the water used by Cedars-Sinai’s cooling towers, offsetting the need for using drinking water for this function.

“Cedars-Sinai is proudly committed to water conservation, and our Ground Water Re-Use System has taken this to a new level,” said Executive Vice President and Chief Strategy Officer Richard B. Jacobs. “Large institutions and companies have a vital role to play in the environmental health of our city, and we are so pleased to do our part. We look forward to working with Mayor Garcetti, LADWP and Metropolitan to advance this important agenda in the years ahead.”

LADWP provided a $155,355 incentive to Cedars-Sinai Medical Center through the Technical Assistance Program (TAP), which offers rebates for the installation of water saving projects and equipment to commercial, industrial, and institutional customers as well as multi-family residential customers in Los Angeles. This joint effort between LADWP and the customer helps modernize the customer’s facility with the latest water-efficient equipment, save on water costs, and conserve water.

“Many customers don’t realize that making investments in efficiency can actually pay for the improvement in reduced energy or water costs in a few short years,” said Wright.  “In this case, the rebate combined with water savings will pay for the total project cost in under five years. We want to partner with more of our customers on projects like this, especially our commercial customers whose water use is about 20% of the total water we supply to the city annually. The more water we save, the less costly, imported water we have to supply our customers, which ensures a resilient water future for Los Angeles.”

Since LADWP’s TAP launched in1991, LADWP has rebated customers a total of $9.5 million for 800 water-conserving projects unique to each customer’s operational needs. To date, TAP is credited with saving1.5 billion gallons (4,500 acre feet) of water, equivalent to enough water to supply 13,500 single family homes on an annual basis.

Cedars-Sinai will also receive about $168,000 from Metropolitan’s Water Savings Incentive Program, which provides a cash incentive to businesses and industrial facilities for the installation of water-saving technologies and devices.

“Metropolitan is looking for opportunities to save water everywhere, in homes, businesses, factories and farms,” said Brad Coffey, manager of Metropolitan’s Water Resource Management Group. “We have a host of incentives and rebates to help anyone who has an idea or project to use water more efficiently, from individuals who want to replace their grass with California native plants, to commercial facilities, like Cedars, that want to install innovative technologies.”

To qualify for an LADWP TAP rebate of up to $250,000, customer must install pre-approved equipment and products which demonstrate water savings. Some examples of past TAP projects include cooling tower water efficiency upgrades, equipment upgrades that replace less water-efficient equipment, and installation of microfiltration systems that enables the reuse of wastewater.
