Background:

Some areas in the City of Windsor are serviced by a combined sewer system which is typical for older areas in most cities. A combined sewer system is a wastewater collection system that conveys a mixture of municipal wastewater and stormwater runoff through a single-pipe system and delivers it to a wastewater treatment plant. During some wet weather (storm) events there is insufficient capacity to carry all of the flow to the wastewater treatment plant which results in excess untreated flow discharging directly into the Detroit River. This is defined as a combined sewer overflow (CSO).

A Windsor Riverfront Pollution Control Planning Study (PCP Study) was initiated by the City of Windsor (City) in 1992 to develop a pollution control strategy along the City’s old riverfront district with the specific objective of reducing combined sewer overflows (CSOs) and total pollutant loadings into the Detroit River; while complying with Ministry of Environment Conservation & Parks (MECP) guidelines.
