The RRRP will only be as successful as it can be proven to prevent sewage and stormwater from overflowing into Nine Mile Run. This makes monitoring a critical element of the overall project. In order to monitor the overall project, you must have baseline data or pre-construction data that will provide a clear picture of runoff entering nearby catchbasins. This is then measured against post-construction data. The result is the total number of gallons of runoff removed by the green stormwater infrastructure from the combined sewer system that overflows into the stream.
As a more long-term measurement of the flow within the pipes in the RRRP area, ALCOSAN has installed monitoring equipment nearby the Oakwood-Batavia installation, and at the overflow on Rosedale Street.
