Rainwater Catchment at CCHRC

The Cold Climate Housing Research Center uses approximately 1/6 of its roof space to catch summer rain. The water is gravity-fed into two 2500-gallon storage tanks in the basement of the facility. From this point the water is used to service the fire sprinkler system, and all toilets in the building. The collected water circulates through the sprinklers then to the toilets, essentially testing the sprinkler system with every flush.

The University of Alaska studied the collected rainwater to gain better insight into the properties inherent to local rain. The study analyzed the corrosive potential of the water in relation to various metals used in domestic plumbing and also experimented with various levels of Ph balancing.
