Monitoring

Monitoring

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.

Pre-construction Monitoring

Pre-construction monitoring equipment was installed in the fall of 2015. It included Telog© data level loggers at 4 catchbasins at the Oakwood & Batavia Streets intersection, as well as, a single data level logger at the catchbasin at the corner of Bennet & Tokay Streets (Crescent ECC). There was also a Rain Gauge installed on the roof of the Crescent ECC to give an extremely accurate localized data stream of rainfall in the RRRP area. All of the pre-construction monitoring equipment was paid for by PWSA.

Post-construction Monitoring

Post-construction monitoring equipment has not been installed yet. All of the equipment will be paid for by PWSA.
