Press Release Summary: SAN LEANDRO, Calif.--(BUSINESS WIRE)--Aug. 5, 2008--Energy
Recovery, Inc. ("ERI") (NASDAQ:ERII), a global leader of ultra-high-efficiency
energy recovery products and technology for desalination, announced that it has been
awarded a contract to provide the energy recovery technology for the Hamriyah (Phase
1) Power Station Seawater Reverse Osmosis (SWRO) Desalination Plant.

Press Release Body: 91,000 m3/day (24 million gallons per day) Hamriyah Seawater

Desalination Plant in Sharjah Selects PX Technology

SAN LEANDRO, Calif.--(BUSINESS WIRE)--Aug. 5, 2008--Energy Recovery, Inc. ("ERI")
(NASDAQ:ERII), a global leader of ultra-high-efficiency energy recovery products and
technology for desalination, announced that it has been awarded a contract to
provide the energy recovery technology for the Hamriyah (Phase 1) Power Station
Seawater Reverse Osmosis (SWRO) Desalination Plant. Aqua Engineering GmbH and ERI
have signed a supply agreement for PX(R) energy recovery devices for the 91,000
cubic meters per day (m3/day) (24 million gallons per day (MGD)) plant to be located
in Sharjah, United Arab Emirates.

The plant was awarded to Austrian company Aqua Engineering GmbH, a subsidiary of
Christ Water Technology AG, by the Sharjah Electricity and Water Authority (SEWA).
The overall capacity of the Hamriyah facility will be 455,000 m3/day (120 MGD) of
fresh water by reverse osmosis technology and 181,000 m3/day (48 MGD) by a thermal
desalination process called multiple effect distillation (MED). This phase of the
project will include 104 PX-260 PX Pressure Exchanger(R) energy recovery devices
which will save an estimated 13 megawatts of power. Designed with a total of eight
(8) SWRO trains operating in parallel, the devices will provide fail-safe redundancy
and reliability with little or no down-time. Currently, the plant is under
construction and scheduled for start-up in 2009. Initial work on the site included a
600 MW power plant. The SEWA project will eventually supply 2000 MW of power and
637,000 m3/day (168 MGD) of desalinated water.

In late 2007, ERI announced the release of its PX-260 device, the latest addition to
its PX technology line of products. The PX-260 is part of the 65-Series product line
and is the Company's largest commercially available energy recovery device, handling
brine flow rates of up to 260 gallons per minute (59 cubic meters per hour) - nearly
20% greater capacity than ERI's former largest device. It operates at the highest
efficiency, providing the best overall energy savings and lowest cost of ownership
of any commercially available energy recovery solution.
The Middle East has been a mainstay for ERI with many small to large plant
installations across the region, ranging from small hotels in Egypt and UAE to
larger projects in Saudi Arabia, among others. The company has a regional sales
office in Dubai.

"This is the fourth plant within a few years for which we have chosen PX technology.
Having installed them in various plant sizes in Oman and UAE, we found these devices
working very reliably and most efficiently," stated Guido Codemo, Process Engineer
for Aqua Engineering.

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
