What Is Rainwater Harvesting?
Water is an important natural resource and is the very basis of our life. We use water for drinking, irrigation, industry, transport and for the production of hydroelectricity. Water is a cyclic resource which can be used again and again after cleaning. The best way to conserve water is its judicious use. Rainwater harvesting is the accumulation and deposition of rainwater for reuse on-site, rather than allowing it to run off. Rainwater can be collected from rivers or roofs, and in many places the water collected is redirected to a deep pit (well, shaft, or borehole), a reservoir with percolation, or collected from dew or fog with nets or other tools. Its uses include water for gardens, livestock, irrigation, domestic use with proper treatment, and indoor heating for houses etc. The harvested water can also be used as drinking water, long term storage and for other purposes such as groundwater recharge. In areas where water supply is less or problematic, rain water harvesting is a good solution. It reduces the use of treated municipal water for uses such as landscaping, toilet flushing and laundry.
