RainBank is pleased to have designed and installed the first rainwater collection system for potable usage in Seattle city limits.  It is supplementary to city water and uses just 3,000 gallons of storage and deionization filtration for collection from an asphalt shingle roof.

The deionization filtration system will remove all toxins from the asphalt roof, and bring the pH level to nominal 7.0. The system will mitigate 65% of the customer’s city water usage. The potable water is of laboratory ultra-pure quality, as proven by samples taken and sent to the lab. The six 530 gallon tanks are a slim line design, enabling placement in a confined area.

Have you thought about rainwater collection for potable usage but were deterred because you have an asphalt shingle roof? Here is your answer.
