New Jersey sewer lines use GA surge relief valves

Dave Heiner Associates, in conjunction with Hatch Mott MacDonald, have successfully completed the design, purchase and installation of GA Industries’ valves for two Bridges Sewerage Authority, Lincoln Park, NJ.
Three 8″ Figure 626-DS Surge Relief Valves specifically designed to protect sewer lines and systems against excessive overpressures were installed on a 30″ force main. With their stream-lined body configuration and hydraulic controlled closings, they minimise surges caused by the normal starting and stopping of pumps, a pump malfunction or power failure.
