The Town of South Berwick is regulated by a general permit through the Maine Department of Environmental Protection (MDEP) for the discharge of stormwater through its separate storm sewer system (MS4). This is called the MS4 General Permit, and it went into effect in 2003. It required the Town to develop a 5 year plan to protect stormwater from pollution.

In 2022, the MDEP issued its fourth General Permit, and the Town updated its 5-year plan to protect stormwater.

The General Permit and 5-year plan require that the Town continue to map its storm drain system, inspect catch basins and outfalls to make sure there are no pollutants discharging to the Salmon Falls River, Great Works River and small streams. 

Under the 5-year plan, the Town will continue to regulate development to ensure stormwater treatment systems get installed and maintained properly, and the Town will inspect and maintain its own stormwater collection and treatment system. 

Public Education and Participation continue to be important elements.  Previously the Town focused on educating residents about the YardScaping Program, which offers alternatives to applying pesticides and fertilizers on lawns.   You can find more information about the YardScaping program at

Moving forward, the Town will focus on cigarette butt litter reduction and proper pet waste disposal.  The Town is collaborating with 4 other towns on this effort and has posted their progress on the Southern Maine Stormwater Working Group (SMSWG) website:  Visit LitteRadar – SMSWG for more information. 

In addition to Pet Waste and Cigarette Butt litter reduction, the Town offers an annual Household Hazardous Waste Collection Day in October(Check Transfer Station page for more information.) Never dump your unwanted chemicals into a storm drain or leave them exposed to the weather. Bring your household hazardous wastes in during South Berwick’s Collection Day to protect our local rivers, lakes and bays from polluted runoff.

They are there to raise awareness about reducing stormwater pollution of our waters.  These catch basins discharge directly to our water bodies – untreated.  Remember:  Nothing but RAIN down the DRAIN.
