Stormwater System Repair in West Springfield, MA

Circle Drive in West Springfield has historically experienced surcharge flooding. EP conducted hydraulic analyses that showed this was caused by an undersized outlet pipe creating a flow restriction, and from seepage in the adjacent embankment.

To fix the problem, EP designed an increased outlet pipe capacity, a slope relief drainage system and an improved double-grated inlet and manhole. Since the storm flow from the system ultimately discharges to Bagg Brook, EP presented this approach to the Conservation Commission for approval prior to construction.
