Rainwater filters are fitted to a downspout between the roof drain/gutter and the storage tank and storm drain system. Filtration diverts or removes most of the initial containments such as leaves, sticks, and other roof debris, that have accumulated on the roof between rainfalls to be diverted away from the storage container. Separating the organic debris from the clean rainwater ensures the stored water quality is not impacted due to anaerobic conditions.
