Rainwater harvesting is one of the most important measures towards water conservation. It refers to the accumulation and deposition of rainwater for reuse before it reaches the aquifer. Uses include water for garden, water for livestock, water for irrigation, and indoor heating for houses etc.. It has proved to be advantageous in several ways. First of all, it makes use of a natural resource and prevents soil erosion and runoff. It also helps avoid contamination of water with chemicals and pesticides. It has proved to be an excellent source of water for irrigation of landscapes, for which one doesn't even need filtration. Home systems are relatively simple to install and help cut the water bill down.
