Water is an extremely precious commodity. Clean, abundant and affordable water does not exist in many parts of the world today. Water shortage is one of the most important limitations of life, agriculture and industries. All the signs suggest that water crisis is getting worse and will continue to do so, unless corrective action is taken. This crisis is essentially caused by the mismanagement of water.To cope with the current and future water scarcity we need to look for alternative water sources and work towards achieving high level of sustainability. One such alternative is the reuse of greywater for irrigation.
