Stormwater Information

Stormwater & Pollution

Stormwater runoff is precipitation (rain or melted snow) that flows over land. Stormwater can pick up pollutants as it runs off the land into lakes, streams, rivers, and the ocean; this is called polluted runoff.

Storm drains collect runoff and convey it without treatment directly into water bodies. Polluted runoff negatively impacts drinking water, human health, wildlife, and property values.

Stormwater Management in Biddeford

The City of Biddeford is working hard to comply with stormwater permit requirements set by the Federal Clean Water Act.

The City meets with the Interlocal Stormwater Working Group (ISWG) every other month to coordinate with other regulated municipalities in implementing portions of their stormwater program.  These meetings are open to the public.  The Cumberland County Soil and Water Conservation District maintains an event calendar with the meeting notices, which can be accessed here:  Cumberland County Soil & Water Conservation District (
