RAIN WATER HARVESTING IN L.D. ENGINEERING COLLEGE
Post: #1

Abstracts: Water resources scarcity is major topics of global discussion in recent years. Rain water is the preliminary source of water. Pounds, lakes, river and ground water the secondary source of water. We depend on the secondary source of water for our requirement, but we forget point that rain water is the source of recharge of water supply for all these secondary source of water. If not harvesting, it floods low lying areas. North Gujarat is water scare region. The rainfall is irregular in nature. Ground water is major source of water and that’s why ground water is declining day by day. It has resulted in the alarming depletion of water level & drastic deterioration in ground water quality.

Rainwater harvesting is a technique for collecting and storing rainwater in reservoirs or natural tanks, or infiltrating surface water into subsurface aquifers (before it is lost as surface runoff). One method of collecting rainwater is harvesting on the roof. With the harvest on the roof, most surfaces - tiles, metal sheets, plastic, but not grass or palm leaf - can be used to intercept the flow of rainwater and provide a home with high quality drinking water and storage throughout the year. Other uses include garden water, livestock, and irrigation, etc.

Rainwater harvesting is the accumulation and deposition of rainwater for reuse in place, rather than allowing it to run off. Rainwater can be collected from rivers or roofs, and in many places, collected water is redirected to a deep well (well, well, well), a reservoir with percolation or collected from dew or mist with nets or other tools. Their uses include water for gardens, livestock, irrigation, domestic use with appropriate treatment, heating of interiors for houses, etc. Harvested water can also be used as potable water, long-term storage and for other purposes such as groundwater recharge.

Rainwater harvesting provides an independent water supply during regional water restrictions, and in developed countries, it is often used to supplement the main supply. Provides water when drought occurs, can help mitigate low-lying flood, and reduce demand in wells that can allow groundwater levels to be sustained. It also helps in the availability of potable water, since rainwater is substantially free of salinity and other salts. The application of rainwater harvesting in the urban water system provides a substantial benefit to both water supply and wastewater subsystems, reducing the need for potable water in the water distribution system.

A large part of the work has focused on the development of life-cycle costing and assessment methodologies to assess the level of environmental impacts and the money that can be saved by implementing rainwater harvesting systems.

More development and knowledge is required to understand the benefits that rainwater harvesting can provide to agriculture. Many countries, especially those with arid environments, use rainwater harvesting as a cheap and reliable source of potable 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 low precipitation, enough water is collected for the crops to grow. Water can be collected from the roofs and dams and ponds can be stored to store large amounts of rainwater, so even on days when there is little or no rainfall, sufficient water is available to irrigate crops.
