It is important to note that chlorination only occurs when the roof water’s chlorine residual drops below 0.5 mg/L, at which water is passed through a chlorination unit and directed back to the filters. This recirculation system was not included in the original SBR design, but its inclusion will ensure that the ponding of water on the roof does not present any water quality and human health concerns. CVC has engaged Toronto Metropolitan University (TMU) to research the water quality of the SBR (among other research areas). Hopefully, this research will demonstrate that rooftop treatment is not required and that treatment before final distribution is sufficient.

When rainwater is drained from the roof surface into the basement, it is collected by a rainwater cistern (CVC’s old, passive system). Water from this cistern can be pumped through the SBR’s second CSA-compliant treatment system. The following are the main treatment components of this basement system:
