The key mechanisms for the SBR’s ability to hold water are the modulating control valves installed on the third floor. The SBR roof drains are configured with valves that stop drainage from occurring.

The City of Mississauga required that CVC install a separate CSA-compliant water recirculation system on the third floor (see Figure 2). This system draws rooftop rainwater through the recirculation line that is immediately upstream of the east modulating control valve. The following are the main treatment components found on the third floor:

The following are the main treatment components found on the third floor:
*'''UV Lamp:''' Disinfects rainwater by sterilizing bacteria and viruses with UV radiation. Note that UV disinfection does not have any residual effect that can be harmful to humans or aquatic life.

*'''Chlorine Pump:''' Provides a chlorine residual of 0.5 mg/L that can ensure that rainwater on the roof surface is protected from recontamination.

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:
