The Norfolk Combined Sewer Overflow (CSO) cleanup project removed contaminated sediments from the Duwamish River to enhance and restore the river habitat.

The Norfolk CSO, or combined sewer overflow, is located near the south end of Boeing Field on the Duwamish River. The CSO is part of the county wastewater system, and discharges run-off and untreated sewage during periods of heavy rainfall when the sewer system is inundated with water.
