Two Bridges Sewerage serves a 56 square mile area with a current population of approximately 40,000 residents.
Three (3) GA Industries 8" Figure 626-DS Surge Relief Valves were installed, which are specifically designed to protect sewer lines and systems against excessive overpressures. The valves were installed on a 30" force main. With their stream-lined body configuration and hydraulic controlled closings, they minimize surges caused by the normal starting and stopping of pumps, a pump malfunction or power failure.
Upon inspection, Rob Knoblauch, who has been with Dave Heiner Associates since 2009, found the original figure 250-DS GA Industries Valves, sold in 1979. They are still in operation today.
