This bears repeating...

The Rideau Valley Conservation Authority (RVCA) is well aware that water directed in the direction of the Jock River, is better than water transferred out of the watershed. The next issue, of course, is the quality of the water. The  RVCA's Jock River Watershed Plan published background Phosphorus levels (in the Jock River) as ranging from 0.05 - 1.10 mg/L. This means that the River's background concentrations of Phosphorus are between 1.6X to 37X higher than that coming from RBC-mechanical treatment plant.

The subject technology has been piloted extensively under the direction of the New York Environmental Protection Agency,  has demonstrated the ability to better the MOE requirements (of 0.03 mg/L) for phosphorous discharge by a margin of over 200%. See the 39-page,1997, Stamford, NY Study, where 0.013 mg/L Phosphorus was consistently achievable.

Letters on file prove the City accepted these pilot results in 1998. The MOE granted a Certificate of Approval in 1998 for an identical plant, and "Policy-2 Receiver" discharge criteria, in Manotick.
