      ENERGY RECOVERY, INC.: Energy Recovery Selected as a Finalist for
               International Innovation Award in Two Categories

The Institution of Engineering and Technology (IET) selects Energy Recovery as
a finalist for the Power/Energy and Sustainability categories for PX Pressure
Exchanger innovation


SAN LEANDRO, Calif.-October 9, 2013 - Energy Recovery Inc. (NASDAQ: ERII), the
leader in harnessing reusable energy from industrial fluid flows and pressure
cycles, announced today that the Company has been chosen as a finalist in two
categories for the Institution of Engineering and Technology's (IET)
Innovation Award for demonstrating its innovative work across engineering and
technology for its game-changing PX energy recovery solution in the
desalination and oil & gas industries. The PX Pressure Exchanger®, lauded for
its precision-engineering, has contributed significantly to global energy
costs-savings and carbon reductions worldwide.

The IET Innovation Awards celebrate the very best innovations in science,
engineering and technology. Energy Recovery's commitment to developing
innovative technologies is rooted in its 20 year history. The company has
filed for more patents in the past two years than its history as a company. By
adapting its principal technology to new sectors such as oil & gas, clean
energy and chemical processing, Energy Recovery upholds that invention is at
the Company's core.

"Over the last two years we've made a concerted effort to return to our roots
as engineering innovators and exploring ways our technology can take on global
energy challenges in various large industries," says Tom Rooney, CEO of Energy
Recovery. "The fact that we are a finalist for both Energy/Power and
Sustainability makes perfect sense - and we are pleased to be listed alongside
this impressive list of fellow innovators."

Industrial processes such as desalination, natural gas treatment, power
generation, and chemical processing are energy intensive and expensive. Energy
Recovery's PX devices make these high pressure fluid flow processes more
sustainable by salvaging and reusing 60% of the energy previously lost, saving
energy, money and reducing CO2 emissions. Installed and used on seven
continents, Energy Recovery technology boasts a 90% market share in the
desalination industry. The economics and environmental benefit continually
underscore this innovation.

The winners of the 2013 IET Innovation Awards will be announced at a black tie
gala Awards Ceremony at The Brewery, in London, November 20, 2013.

The full list of finalists for all categories can be seen on the IET
Innovation Awards website. For more information on the PX Pressure Exchanger,
