Green buildings, as we all know, refers to both a structure and the application of processes that are environmentally responsible and resource-efficient throughout a building's life-cycle: from planning to design, construction, operation, maintenance, renovation, and demolition. Well, the most of the efforts are directed towards creating greener constructions, the new practice or objective is also to help both home and office owners to reduce waste, environmental degradation and pollution. One of the best examples of green building practices is rainwater harvesting.
Experts say that by harvesting rainwater the use of drinking water for various domestic, industrial and agricultural purposes can not only be reduced but the devastating effects of drought and rainfall can also be minimized. Water harvesting has also a positive effect over groundwater. Adopting methods to increase groundwater recharge is another essential green building practice because groundwater protects the environment against climate changes.
Rainwater harvesting systems can broadly classified as passive and active. Though rainwater is non-potable, it can be safely used for activities like washing cars and lawn irrigation etc. Active systems often uses pumps to supply the water to the distribution. The active systems may also include water treatment arrangements so that rainwater is made safe for washing, toilet flushing and evaporative cooling. Passive systems are actually small barrels placed at the end of downspouts.
Harvesting rainwater reduces Flooding and Erosion, and also water bills. It can improve plant growth. Can also be used for almost all non-drinking purposes and hence reduces demand on ground water.
Green building design must ensure rational use of natural resources.
