SAN LEANDRO, Calif. — April 7, 2020 — Energy Recovery, Inc. (NASDAQ: ERII) today announced awards of USD $8.3M to supply its PX® Pressure Exchanger® devices (“PX”) and related equipment and services to multiple desalination projects in Egypt.

“Energy Recovery prides itself on being a trusted partner to the desalination industry, and we remain dedicated to serving our customers as we adjust to the impacts of COVID-19. The reputation of our PX and its lifetime value proposition are unmatched, and we are focused on fulfilling orders from existing inventory as well as booking new orders. Desalination plants are a critical part of the fresh water infrastructure of many countries, and we are proud to play our part in delivering affordable, clean water to the people of Egypt,” said Robert Mao, Energy Recovery Chairman and Interim President and Chief Executive Officer.

The desalination plants included in this award will have a collective capacity of 290,000 cubic meters per day. Once the plants are in operation, Energy Recovery’s PX devices are expected to recycle hydraulic energy equivalent to over 300 gigawatt hours of energy annually, an amount associated with approximately 200,000 metric tons of carbon emissions.

“Egypt’s population is growing quickly, and, according to the United Nations, the country’s per capita share of fresh water means it is on the verge of absolute water scarcity. Egypt has identified desalination as part of its strategy to improve freshwater security, as desalination offers a cost-effective means to diversify supply beyond variable sources such as the Nile River,” commented Rodney Clemente, Energy Recovery Senior Vice President of Water. “The country is amidst an aggressive build-out of desalination facilities that is likely to continue at least through 2024 and exceed over 1 million cubic meters per day of new capacity for the municipal sector alone. Energy Recovery has been awarded seven mega-plants (plants exceeding 50,000m3/d) in Egypt to date, and we plan to continue to do our part to help Egypt meet these exciting challenges head-on.”
