PS&S undertook the evaluation of an existing 100,000-gallon elevated water storage tank (located at the Borough’s Union Lane DPW yard) which was experiencing low water turnover, diminished HGL levels, and structural deficiencies.
As part of a holistic approach, PS&S was authorized to evaluate water movement throughout the Borough’s entire water distribution network via WaterCAD modeling in order to determine optimal tower water levels in both of the Borough’s existing tanks, and to evaluate the feasibility of eliminating or replacing the Union Lane Elevated Tank.
THE PS&S SOLUTION
PS&S analyzed the water age, water movement between two separate pressure zones, and chlorine residual levels. Solutions included the addition of new, pressure reducing valve (PRV) pits at optimum points on the pressure zone boundaries, new transmission mains at critical junctions, and replacement of the existing tank with a lower HGL tank. Ultimately, a decision was made to design a new 300,000-gallon elevated tank, which will provide higher operating pressures and a more reliable water storage source for Brielle residents and businesses. Project funding was secured via a NJEIT low-interest loan.
