Rainwater harvesting is the accumulation and storage of rainwater for reuse at the site, rather than allowing it to drain. Rainwater can be collected in rivers or roofs, and in many places, the collected water is redirected to a deep well a percolation deposit, or collected from dew or fog with networks or other tools . Its uses include water for gardens, livestock, irrigation, domestic use with adequate treatment, interior heating for houses, etc. Harvested water can also be used as drinking water, long-term storage and for other purposes, such as groundwater recharge. Rainwater harvesting is one of the simplest and oldest methods of water self-supply for households generally financed by the user.
Rainwater harvesting provides an independent water supply during regional water restrictions, and in developed countries, it is often used to supplement the main supply. It provides water when a drought occurs, it can help mitigate flooding in low-lying areas and reduce the demand for wells that can allow groundwater levels to be maintained. It also helps in the availability of drinking water, since the rainwater is substantially free of salinity and other salts. The application of rainwater in the urban water system provides a substantial benefit to the water supply and wastewater subsystems by reducing the need for clean water in the water distribution system, less rainwater generated in the water system. sewerage and a reduction in stormwater runoff.
A large amount of work has focused on the development of life cycle assessment and life cycle costing methodologies to assess the level of environmental impact and money that can be saved by implementing collection systems of rainwater.
More development and knowledge is required to understand the benefits of rainwater harvesting that can be provided to agriculture. Many countries, especially those with arid environments, use rainwater harvesting as a cheap and reliable source of clean water. To improve irrigation in arid environments, soil ridges are built to trap and prevent rainwater from flowing down hills and slopes. Even in periods of little rain, enough water is collected for crops to grow. Water can be collected from roofs, and dams and ponds can be built to hold large amounts of rainwater, so that even on days when there is little or no rain, there is enough water to irrigate crops.
