Macomber Stadium

The Narragansett Bay Commission is implementing final phases to reduce Combined Sewer Overflows (CSO) in Pawtucket and Central Falls. One part of this large endeavor is the award-winning green stormwater infrastructure (GSI) project at the Macomber Stadium located in Central Falls.


A combined sewer system (CSS) collects rainwater runoff, domestic sewage, and industrial wastewater into one pipe. Under normal conditions, it transports all the wastewater it collects to a sewage treatment plant for treatment, then discharges to a water body.” 

– U.S. EPA

In 2020 and 2021 this project received awards from two vastly different organizations. First, a “Stormy Award” from the New England Stormwater Collaborative recognized the project as the “Best Stormwater Idea” at the annual New England Stormy Awards. Second, more recently,  the American Sports Builder’s Association named Macomber Stadium “Outstanding Single Field Facility of the Year,” which is a national award. Awards aside, we are proud to have worked with NBC and collaborated on this GSI project with Pare Corp., and Stantec.

The new state-of-the-art synthetic turf athletic field includes a subsurface infiltration system and sand filter with enough capacity to treat and infiltrate a 25-year design storm. The system captures runoff from over six acres of surrounding impervious surfaces. Other GSI features include a permeable paver mezzanine and stormwater bio swales. New landscaping also provides streetscape appearance and overall curb appeal.  The project also restored a contaminated site to its highest potential. Over 10,000 tons of contaminated soils were removed while other soils were encapsulated under an engineered cap that doubles as the final site surface.
