*'''Solenoid Valve:''' Determines when chlorination is allowed to occur by opening when the rooftop chlorine residual is too low.

*'''Solenoid Valve:''' Determines when chlorination is allowed to occur by opening when the rooftop chlorine residual is too low.

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.
