Rainwater is harvested from the existing roofs of the ranchos and fed to a rainwater storage tank. Depending on the frequency and amount of water during rainfalls the level of water in the tank varies.
The harvested rainwater from the tank is used for irrigation of vegetables. Depending on the level of water in the storage, different plants are irrigated. The plant most sensitive to draughts, lettuce, is irrigated even when the level is lowest. The system is automated and controls how much water each type of plant receives.
The organic waste of the plants is collected and disposed in the composting units, where the organic material is decomposed and then used to enrich the soil of the plant beds.
