Innovative project makes history as first to mutually reduce water, energy use

Sponsored by

COMMERCE, CA, Aug. 21, 2014 -- The U.S. Department of Energy has awarded the Central Basin Municipal Water District (MWD), located in the city of Commerce, Calif., with a new grant that will make history as the first project aimed at reducing water and energy consumption simultaneously.

MWD will use the funds to retrofit public facilities, implement a notification awareness program and install software to manage water and energy use in its recycled water delivery system.

"This project is an example of an innovative approach to address two vital resources in Southern California," said MWD General Manager Antonio Perez. "Providing the cities and communities with these resources will assist in reducing water and energy consumption in our region."

The retrofit component of the grant will provide qualifying public facilities, such as school districts, city-owned properties and non-profit organizations, with free water-efficient devices and installation. Qualifying sites will also be provided with a facility inspection that includes an in-depth analysis of their water-use practices.

The results of the inspection will help determine the recommended retrofits. Devices available for retrofit include high-efficient urinals and toilets, faucet aerators and rotating nozzles.

Funding from the grant also includes the development of a notification awareness program. The web-based platform will be made available to water retailers to send inter-agency notifications on water usage, drought emergency and conservation measures.

To further reduce energy and water use, MWD will also utilize grant funding to install a supervisory control and data acquisition (SCADA) program in its recycled water delivery system. The pumps in the recycled water system use a large amount of energy due to the constant on and off-cycling. The SCADA program will reduce energy consumption by adjusting the schedule of the water pumps.
