Rainwater is collected from the roof of a 350 square foot garden structure and stored in a 343 gallon green polyethylene tank located on an 14 inch high platform made of 4 X 4’s placed on gravel bed adjacent to the structure. The system uses a Rainkeeper Downspout Collection Filter to filter the rainwater. Overflow is piped to a 50 gallon recycled olive barrel.
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 5950 gallons for the season from 350 sq ft of roof collecting area.
