Northampton Stormwater System
Public Works is responsible for the city's stormwater system which includes upwards of 114 miles of stormwater pipes, 4,835 catch basins, 326 outfalls, 190 culverts, and many drainage ditches along roadways. Each year public works staff clean out catch basins and repair and maintain the drainage system as necessary to keep the system functioning safely and to reduce flooding.

Northampton has a separate stormwater system that collects rainwater and snowmelt from the streets, parking lots, sidewalks and buildings and carries this water directly to brooks, wetlands, rivers, and other water bodies throughout the city. Unlike the (completely separate) wastewater system, the water collected in street drains is not treated at our treatment plant before flowing to these natural water bodies.

Since 2003, a Stormwater Management Plan has been implemented in complicance with the U.S. Environmental Protection Agency (EPA) National Pollutant Discharge Elimation System (NPDES) Stormwater Phase II MS4 General Permit. For more information about the EPA Stormwater General Permit, click here.
