SustainRain® Filter Basins from Complete Aquatics are used for rain garden systems and rain harvest systems. The high-capacity, professional-grade basin is designed to provide mechanical filtration and direct harvested rainwater from the surface of a roof to the SustainRain® storage area. The SustainRain® Filter Basin is installed below ground, easily blending into the landscape. In the event of debris blockage or extreme storm surges, the built-in direct bypass system allows the rainwater to be diverted to the overflow system, away from the building.
SustainRain® Filter Basins can be installed anywhere in between the downspout coming from the building and the rain garden or rain harvest storage system. It comes complete with all the necessary fittings to connect either to corrugated drainpipe or schedule 40 PVC.
