Climate change, the unapologetic use of natural resources and the subsequent threat to the environment is a global phenomenon that the world is not unaware of. 

Fresh Water is one of those natural resources which is extremely important to support human life and existence, and is finite. The irresponsible consumption and wastage of water have led to the scarcity of ground and surface water. Following the alarming scarcity of water, the concepts of water conservation and harvesting are being revisited. The systems and practice of conserving water date back to ancient India where Vav (Stepwells), talabs (reservoirs), wells etc., amongst many others were used, varying with cultural and geographical diversity across the Indian subcontinent. 

The concept of rainwater harvesting has been promoted, as a sustainable and ecological practice, as a solution to the problem of water scarcity, particularly in urban areas. The idea behind the concept was to harvest rain wherever it falls, for underground recharge or store for future use, thus promoting self-sufficiency while being environmentally responsible.

The process includes collecting Rainwater from terraces and balconies into a harvesting tank for later use. The excess water can be sent to the ground through bores and thus increase the ground water level. The waste water from bathrooms and kitchens can thus be reused for gardening and car-wash etc., after being bio-chemically or organically treated.

Apart from being a sustainable and ecological water conservation method, rain water harvesting can help people measure their individual water usage, and thus encourage the process of water conservation. It can also make a community self-sufficient by reducing their reliability on transported water supply. 

Harvested rain water can be a back-up water supply for emergency situations while it can also be used as a primary water supply for certain functions.

The present day circumstances call for an immediate response and action towards water conservation, so as to create a better environment for the generations to come.
