Part Number: RMS-1100-B
For Roof Collection Areas up to 1,100 square feet
The RMS 1,100 Square Foot Rainwater Collection Kit Below Ground is a complete rainwater harvesting package designed for roof collection areas up to approximately 1,100 square feet utilizing a below-ground storage tank. This package combines efficient rainwater collection, filtration, storage, and pumping components to create a reliable water source for residential and light commercial applications.
Rainwater enters the system through the WISY Garden Downspout Filter, which removes leaves, debris, and roof contaminants before water is conveyed to the storage tank. Once collected, water is delivered on demand through the highly efficient Grundfos SBA 3-45 submersible pump system. Because the pump is installed inside the tank, the system operates quietly while eliminating the need for a separate external pump house or pump enclosure.
Designed for homeowners seeking a clean, professional, and space-saving rainwater harvesting solution, this package provides dependable performance for irrigation, landscape maintenance, gardening, and other non-potable water applications while helping reduce dependence on municipal water supplies.
