The contamination of Toledo, Ohio’s water supply by the algae-bloom-derived toxin microcystin reinforces the value of harvesting rainwater to provide distributed sources of safe water. The mission of the 501(c)3 nonprofit American Rainwater Catchment Systems Association ( is to promote sustainable rainwater harvesting practices to help solve potable, non-potable, stormwater and energy challenges throughout the world.  


A well-designed, installed and maintained rainwater harvesting system can provide significant amounts of high-quality water for potable and non-potable, residential and commercial use. Given Toledo’s average 34 inches of annual precipitation, a 1,500-square-foot residential roof could collect over 30,000 gallons annually, delivering more than 84 gallons per day of high-quality water for potable and/or non-potable uses. A commercial roof of 100,000 square feet could collect over 2 million gallons annually.


Attesting to the quality of treated rainwater, ARCSA board member Jack Holmgreen won a Gold Medal for his rainwater entry in the 2011 Berkeley Springs (West Virginia) International Water Tasting competition. ARCSA is gathering funds, experts and technical writers to create a national rainwater harvesting manual and is soliciting tax-deductible donations.
