This 200 square foot galvanized steel roof and wood shade structure was built to provide shade and a water collection surface. The roof pitches to the center and rainwater is collected in a custom made gutter where it is funneled to the storage tank. The water is collected in a 343 gallon green polyethylene tank located on an 14 inch high platform made of 4 X 4s placed on gravel bed. The overflow and winter flow is directed to a low area at the edge of the garden. Rainwater is filtered using a Rainkeeper Downspout Collection Filter. This system was built by Green Apple Corps members and volunteers 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 3400 gallons for the season from 200 sq ft of roof collecting area.
