Rainwater is collected from the roof of a 500 square foot adjacent 2 story roof and stored in 4 - 50 gallon recycled olive barrels linked together and draining from one hose bib. The barrels are raised on an 14 inch high platform made of 4 X 4s placed on gravel bed along the garden fence. The system uses a Rainkeeper Downspout Filter to filter the rainwater. There are overflows located on each end of the row of barrels directed toward ornamental areas of the garden.
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 8500 gallons for the season from 500 sq ft of roof collecting area.
