Stormwater Management

Unlike some other nearby communities, Watertown has separate sewer and stormwater drainage systems. The drain pipes do not go to Deer Island to be treated like sewage from your house is. Instead, stormwater drainage is collected through catch basins, conveyed through drainage pipes, and then discharged into the Charles River, all with little to no treatment.

Illicit Discharge Detection & Elimination (IDDE)

An illicit discharge is the discharge of pollutants or non-stormwater materials to the stormwater drainage system. The result is untreated discharges that contribute high levels of pollutants, including bacteria, heavy metals, toxins, oils and grease, solvents, and nutrients to receiving bodies, like the Charles River.

Capital Projects and Planning

The DPW is responsible for managing the City’s infrastructure assets, including its roads, intersections, water and sewer utilities, and drainage systems. Capital planning activities include programming and implementation of the City’s Pavement Management Plan, Water System Study, and various sewer studies. DPW also manages the City’s Chapter 90 road program and is responsible for long term planning on corridors such as Common Street and Mount Auburn Street.
