Welcome to the Lower Oak Park and Highland Park Sewer Separation Project

The City of Des Moines is initiating a new Project which is included in the City’s Long Term Control Plan, developed to eliminate combined sewer overflows (CSO). The Lower Oak Park and Highland Park Sewer Separation Project is located along the Des Moines River, north of downtown. Currently, stormwater in this area is collected and conveyed by both separate storm sewer and combined sewer systems. The combined storm sewer and sanitary sewer flows are conveyed to the Birdland Pump Station on Saylor Drive, south of the marina.
