A word from the owner I have been interested in rainwater collection for many years. Due to poor ground water, lack of municipal supply, and environmental considerations, I began to look into collection systems. My rainwater system supplies all my indoor water needs. Leaves, seeds and sticks were initially a huge problem for my system. I first tried flush type filters, and other types of screen filter roof washers. I found them to be ineffective at best and high maintenance at worst. WISY filters have solved these issues and need to be cleaned only once or twice per year. These patented products benefit greatly from 15 years of experience in the field and worldwide installations from rain barrels to large factory complexes. -Joe Wheeler- |
