Holland BPW maintains all of the sanitary sewer collection system south of Lake Macatawa and the Macatawa River. This system contains nearly 190 miles of sanitary sewer pipe and WWTP34 sewage lift stations.

While the system is mostly within the City of Holland, it also includes portions of Park, Laketown, Fillmore and Holland Township.

This system is separated, which means the surface drainage is collected into storm sewers and drains, and the sewage from your home or business goes into a separate system – the sanitary sewer system.
