We are the exclusive U.S. dealer for WISY filter products: The best in rainwater harvesting worldwide!

Self-cleaning WISY filters operate as a first flush device, directing leaves, dirt, and other debris to the stormwater system and diverting up to 95% of the clean rainwater to a storage tank. 

The Smoothing Inlet prevents incoming water from stirring the tank and oxygenates the water. 

The Floating Filter ensures intake of the cleanest water from just below the water surface.

The Multi-Function Overflow Device skims floating particulate on the water surface and protects water quality.
