• Marks first Heliscreen order in U.S.

PORTLAND, ME, Sept. 9, 2009 -- Hydro International, a leading provider of environmentally sustainable products and innovative solutions that control and treat stormwater, wastewater and combined sewer overflows, today announced that its U.S. business received its first domestic order for a Heliscreen® screening system.

While Hydro International has installed hundreds of Heliscreen systems in the United Kingdom, the project in Farmington, Missouri, is Hydro's first Heliscreen installation in the U.S. The Heliscreen system will be used as part of a combined sewer overflow (CSO) mitigation project at Farmington's East Treatment Plant.

The Heliscreen is a compact powered CSO screening system with the ability to operate under surcharged conditions. With low headloss and a small footprint, the Heliscreen works well in retrofit installations with hydraulic or physical site constraints. The Heliscreen is a quarter-inch (6 millimeter) perforated screen designed to handle a peak hourly flow of 8.1 million gallons per day.

Farmington's East Treatment Plant is conducting the CSO mitigation project to adhere to stricter environmental laws. The CSO screening system is part of a plant enhancement and expansion to accommodate an increase in the average flow capacity from 1.3 million to 2 million gallons per day.

"We're thrilled Farmington has chosen Hydro's Heliscreen for its Combined Sewer Overflow screening application," said Neil Raymond, general manager of Hydro International's Wet Weather business. "Communities face major challenges solving CSO issues, and the Heliscreen offers an efficient, cost-effective solution. We're excited about its market potential here in the U.S."
