We built a Rainwater Harvesting system at the Joe Holska Community Garden in Staten Island, New York. The collection area is a 10 Ft wide by 20 Ft long by 8 Ft high wood pavilion with a sheet metal roof . The crew were members of the Green Apple Corps with assistance of staff from CENYC and direction from Lenny Librizzi. A custom made gutter directs rainwater to a screen filter/ diverter and then to a 343 gallon tank. A 3/4 inch hose bib is used to drain the tank. The filter / diverter allows for shutting down and winterizing the system. Materials and labor were funded through a contract between GreenThumb and CENYC. Video by Lenny Librizzi.
The structure is approximately 200 square feet. Assuming between .5 and .6 gallons collected per square foot, in a 1 inch rain we would collect between 100 and 120 gallons of rainwater.

How much rain water is collected from the roof system with say a 1" of rainfall?
