Integrated Sustainability completed a detailed review of a rainwater harvesting system designed to supply vehicle rinse water from roof and parkade runoff.

project deliverables

• Reviewed 45% design documents for a non-potable rainwater reuse system.
• Evaluated filtration, chlorination, and deionization plans for vehicle rinse water.
• Analyzed potential risks from aerosols, biofilm growth, and residual spotting.
• Identified design gaps including lack of first flush diversion and chlorine CT validation.
• Provided recommendations for seasonal diversion, alternative de-icing, and monitoring upgrades.
