This rainwater harvesting package includes everything you need (but the storage tank) to harvest rainwater from roofs up to 2,200 ft sq. It includes the Vortex Rainwater Filter , a smoothing inlet to aerate water entering the tank, a suction pump that pulls water from the tank, a storage tank level indicator, a float switch for dry run prevention, and an in-tank floating filter and hose. The floating filter further cleans the water as it is pumped from the tank for toilet flushing, irrigation, janitorial use and other non-potable uses.
