Cobble Mountain Reservoir Culvert Daylighting

EP is working with the Springfield Water and Sewer Commission to improve drainage and water quality to the Cobble Mountain Reservoir, located in Blandford, MA, by improving stream crossings within the reservoir.

The Cobble Mountain Reservoir serves as the Commission’s main drinking water supply for the greater Springfield, MA area. The first phase of this work focuses on daylighting a failing 18-inch diameter culvert. During our work, EP will conduct a site assessment, Hydrologic-Hydraulic (H-H) Model, and design and permitting of the removal of the existing culvert and restoring the stream back to more natural conditions.

The project, once complete, will reduce maintenance, remove the blockage due to woody debris buildup at the culvert and reduce sediment entering the reservoir.
