The RainXchange system combines sub-surface rainwater collection with an above-ground recirculating water feature. Rainwater from the gutters collects in an underground rain filter and is then sent to a modular storage basin; water is pumped to either the irrigation hose or recirculates through the above-ground decorative water feature and biological filter and back into the storage basin. An overflow tank allows excess rainwater to infiltrate the soil and aquifer.
Projects include geothermal systems, rainwater catchment, ICFs, and straw bale construction.
