We are reducing polluted stormwater runoff throughout the local communities across the Neponset Watershed with assistance from grants, partnerships, and volunteers.
- bacteria and parasites from pet waste
- chemicals from fertilizer, pesticides, herbicides
- Phosphorous from leaves and grass clippings
- snow/ice melt chemicals and sand
- motor oil, antifreeze, and transmission fluid
- all types of litter
Storm drains are connected via underground pipes to nearby water bodies, and all of the contaminated runoff flows directly into local streams, rivers, ponds, and the ocean, untreated.
Polluted stormwater causes problems for local drinking water sources; recreational activities like swimming, boating and fishing; and aquatic life.
The simplest way to prevent stormwater pollution is to keep our pavement clean and redirect water away from storm drains
NepRWA Helps Communities thru Partnerships
On July 1, 2018, the Environmental Protection Agency finalized a tough new stormwater permit for local municipalities.
We plan to help our communities with their stormwater cleanup efforts through regional cooperation and resource sharing, under the umbrella of the Neponset Stormwater Partnership (NSP).
The partnership communities are cooperating on creating key permit documents, printing regional public outreach materials, creating model stormwater bylaws, and figuring out the best way to pay for it all. The goal is more effective cleanup at a lower cost, through economies of scale.
Partners include the towns of Canton, Dedham, Foxborough, Medfield, Milton, Norwood, Quincy, Sharon, Stoughton, and Westwood, along with the Metropolitan Area Planning Council (MAPC), and the Neponset River Watershed Association.

Additional Projects Include:
With few exceptions, most Neponset Watershed stormwater enters the river untreated – a major contributor to Neponset River’s failure to meet fishable/swimmable water quality standards during wet weather.
Over the past few years, NepRWA has been working with towns to find the best places to install structural stormwater Best Management Practices (“BMPs”) to help to treat stormwater and clean it before it discharges to the river.
- Dedham BMP sites
- Stoughton/Gibbons School Rain Gardens
- Soak up the Rain/Xaverian Brothers High School Project
Best Management Practices (BMPs)
Before the landscape was developed, far more rainwater would seep into the ground and be filtered by soil, plant roots and microorganisms, before joining the groundwater or seeping from the soil into a waterway.
Today, realizing just how much of the ground has been covered in impervious material, communities are incorporating stormwater-cleaning structures, called BMPs into the built landscape. Examples of BMPs include bioretention cells, rain gardens and tree-filter-boxes.
