Reducing Energy Costs

Energy Recovery, Inc. ("ERI") (NASDAQ:ERII), a global leader of
ultra-high-efficiency energy recovery products and technology for sea water
desalination, announced that the company's PX Pressure Exchanger(R) (PX(R))
technology has been selected by IDE Technologies to be the energy recovery device
(ERD) solution for the Hadera Sea Water Reverse Osmosis (SWRO) Desalination Plant.
The project is currently under construction and is scheduled for completion in 2009.


The Hadera plant, located between Tel Aviv and Haifa in Israel, is being designed
and built by IDE Technologies. It will initially produce 100 million cubic meters
per year (m3/yr), or 274,000 m3/day (72.3 million US gallons per day (MGD)) of fresh
water and may eventually be expanded to supply 130 million m3/yr (94 MGD). The plant
is designed with PX-220 Pressure Exchanger energy recovery devices. These devices
will save over 34 mega-Watts (MW) of energy compared to operating without an energy
recovery solution.

IDE also recently selected PX Technology for the expansion of its 54,000 m3/day (14
MGD) SWRO desalination plant located in Larnaca, Cyprus. By utilizing advanced
energy recovery technology from ERI, the plant will continue to operate the same
high-pressure pumps and energy recovery turbines but will increase capacity and
improve energy efficiency. The overall production capacity will increase by nearly
20% to 64,000 m3/day (17 MGD) while SWRO energy consumption will reduce from
approximately 3.2 to 3.0 kWh/m3.
IDE selected PX technology for both projects over competing devices due to a proven
track record in reliability, high efficiency and energy savings, as well as having
the smallest physical footprint.

"The Hadera project is particularly rewarding for our team," stated Borja Blanco,
ERI Vice President and GM of the Mega Projects Division. "We had to convince a very
skilled and knowledgeable contractor who had significant experience with a competing
technology," continued Mr. Blanco. "New customers believe in our PX technology and
it becomes apparent when the world's largest plant designers select ERI's devices
and customer service and support over the competition," stated ERI CEO and
President, G.G. Pique.

About ERI(R)

Energy Recovery, Inc. (ERI) is a leading manufacturer of energy recovery devices,
which by significantly reducing energy consumption is helping make desalination
affordable. ERI's PX Pressure Exchanger(R) technology (PX(R)) is a rotary positive
displacement pump that recovers energy from the high pressure waste stream of sea
water reverse osmosis systems at up to 98% efficiency with no downtime or scheduled
maintenance.

The company has research, development and manufacturing facilities in the San
Francisco technology corridor as well as direct sales offices and technical support
centers in key desalination hubs such as Madrid, UAE, Shanghai and Florida. ERI
service representatives are based in Algeria, Australia, China, India, Korea,
Mexico, Taiwan and the Caribbean.

As the demand for clean, potable water increases; ERI is poised to face the global
challenges ahead. For more information on ERI and PX technology, please visit
