A cluster consists of rainwater collection, storage of rainwater, plant beds and compost. Each cluster could function individually but the idea is that excess water and compost materials feed the cluster at a lower level. The first cluster will be fed by a compost of organic material from the green area at the top of the hill.
The compost is a unit where organic waste is disposed at the lowest part of one cluster and the decomposed material is used to enrich the soil of the cluster at the next level. Each compost is paired so that while one is used, the organic material of the other one is decomposed which takes a few weeks.
