What is RWH?
Rain water harvesting is collection and storage of rain water that runs off from roof tops, parks, roads, open grounds, etc. This water run off can be either stored or recharged into the ground water. A rainwater harvesting systems consists of the following components:
catchment from where water is captured and stored or recharged,
conveyance system that carries the water harvested from the catchment to the storage/recharge zone,
first flush that is used to flush out the first spell of rain,
filter used to remove pollutants,
storage tanks and/or various recharge structures.
Why do RWH? Rain may soon be the only source of clean water. Rainwater harvesting systems use the principle of conserving rainwater where it falls and have the following benefits:
Setting up a rainwater harvesting is not difficult but requires some sort of understanding of hydrology and architecture and as a result most people find it too complicated to do it themselves. In order to make it simple and convenient for everyone to set up a rainwater harvesting system suitable for their needs, we have prepared a set of guidelines which will help you to set up your own rainwater harvesting system quickly and efficiently.

The increase in urbanisation has led to increase in the fresh water demand along with wastewater generation. The current water crisis is attributed to mismanagement of water resources and emphasis on the energy as well as resource intensive centralised urban water management. Need is, for the practitioners and user communities, to implement sustainable and affordable decentralised water management practices. This short term five day course will focus on – designing rainwater harvesting (RWH) and decentralised wastewater treatment (DWWT) systems including local reuse.
