Rainwater Harvesting Can Create Safe, Decentralized Water Supplies
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
ARCSA 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. For more information, please contact Heather Kinkade,
Executive Director ARCSA, at 512-617-6528 or info@arcsa.org.
