Rainwater is collected from the roof of the adjacent 800 square foot 3 story building and stored in a 1000 gallon green polyethylene tank located on a 14 inch high platform made of 4 X 4s placed on gravel bed adjacent to the building. The system uses a Rainkeeper Downspout Filter to filter the rainwater. Overflow is piped to an adjacent area of the garden. The system was built with the assistance of community gardeners under the supervision of GrowNYC staff. Based on an average rainfall of 34 inches during the season from March 1 to Oct 31 and .5 gallons of rain collected per square foot of roof area, we estimate having the potential to collect 13600 gallons for the season from 800 sq ft of roof collecting area.
