The system is designed to distribute water to a 50 m 2 farm plot using local materials found in rural Nicaragua. The water reservoir is an 80 L / 20 gal water sack consisting of a garbage bag reinforced with a sack. Filtration takes the form of a cloth, such as a piece of old clothing, wrapped around a 2 L plastic bottle (cut in half). Technicians use a drill to manually create water holes throughout the drip tape hoses.
