Abstract:

As the world population increases, the demand increases for quality drinking water. Rainwater harvesting systems (RWHS) have been accepted as a simple and eff ective approach to ease the worsening of water stress. Rainwater harvesting is defined as the accumulation and deposition of rainwater for reuse on-site, rather than allowing it to run off. Many countries around the world are facing water shortages. Optimization of water usage and the conservation of water as a natural resource can help to overcome water shortage. Rainwater can be used for potable and non-potable uses. In a typical rainwater harvesting situation, rainwater is collected from an impervious surface such as the roof of a building and then stored inside a tank or cistern. Other surfaces include parking lots, roadways, driveways, and even land surfaces (once surface runoff from the land surface begins). Rainwater can be harvested and stored for many uses including landscape irrigation, potable and non-potable indoor use, and storm water management. RWH systems has been investigated using different approaches, including water balance simulation analyses and mass curve analyses , probabilistic methods and economic optimization . The main advantages of rainwater harvesting systems are conserving water resources and environment, pollution reduction, help to control flooding, and reduction of impact of weather change.
