The Rain Harvesting Corridor is a 85’ x 12’ roof structure located between a rammed earth tire retaining wall and an adjacent building. Its primary structure is a concrete beam frame with triangular patterns carried on one side by the adjacent building and on the other side by columns leaning against the rammed earth tire retaining wall.

The beams carry individual 4” thick concrete vaults and slope towards a gutter located along the retaining wall. Each vault is split in the middle and presents different curvatures on each half in order to create an opening which lightens the corridor below. Additionally, glass-bricks (two bottoms of glass bottles taped together) are tied in the reinforcement of the vaults and act as skylights.

The rainwater falls on the vaults and is guided towards the gutter leading to a 42,500-gallon cistern located on the East of the corridor. The roof of the adjacent building is also sloped towards the harvesting corridor in order to maximize the amount of rainwater collected.
