MS4 & Think Blue

MS4 & Think Blue

MS4 is an abbreviation for Municipal Separate Storm Sewer System. “A separate storm sewer system is a collection of structures, including retention basins, ditches, roadside inlets and underground pipes, designed to gather stormwater from built-up areas and discharge it, without treatment, into local streams and rivers. It’s called a separate system because it’s not connected to the sanitary sewer system which drains waste water from inside a home to a sewage treatment facility or a private septic system” (Penn State Extension).

Groveland is currently in compliance with the Massachusetts MS4 Permit. The Town’s 2022 Stormwater Management Plan can be found linked below.
