RainSource’s rainwater pumping & filtration systems are designed in-house to meet individual building specifications and CSA Rainwater Harvesting standards. We use proprietary tools and historical weather data to determine system feasibility, possible end-use applications, cistern sizing and more. Our clients work directly with a RainSource ASSE & CANARM-certified rainwater harvesting systems designer to build the perfect system for their building. All systems are skid-mounted with welded stainless steel piping assemblies.
