The Rainbow Hostel is located close to Golfito, Costa Rica. This forming community intends to serve as a learning center for social sustainability. A gravity fed, rainwater catchment system supplies all of the water for the main house which includes sinks, showers and toilets.

Rainbow 4 Black Tanks

Lower system[edit]

Rain water is collected from roof of the main house with gutters (Fig 1). The water passes through screen to filter out debris (Fig 2). Water then flows to 3 tanks and then is gravity fed to the downstairs of main house and bathrooms.

Upper System[edit]

Water from the upper system (Fig 1) goes from a small roof (Fig 2) and through a concrete tank filled with sand (Fig 3). The water is filtered through the sand and is stored in an upper tank (Fig 4). This water gravity feeds the upstairs of house.
