Why rainwater harvesting? In many regions of the world‚ clean drinking water is not always available and this is only possible with tremendous investment costs and expenditure. Rainwater is a free source and relatively clean and with proper treatment it can be even used as a potable water source. Rainwater harvesting saves high-quality drinking watersources and relieves the pressure on sewers and the environment by mitigating floods‚ soil erosions and replenishing groundwater levels. In addition

Rainwater harvesting In urban areas‚ the construction of houses‚ footpaths and roads has left little exposed earth for water to soak in. In parts of the rural areas of India‚ floodwater quickly flows to the rivers‚ which then dry up soon after the rains stop. If this water can be held back‚ it can seep into the ground and recharge the groundwater supply. This has become a very popular method of conserving water especially in the urban areas. Rainwater harvesting essentially means collecting rainwater

RAINWATER HARVESTING WHAT IS RAINWATER HARVESTING? Rainwater harvesting is 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. In many places the water collected is just redirected to a deep pit with percolation. The harvested water can be used as drinking water as well as for storage and other purpose like irrigation. ADVANTAGES Rainwater harvesting

Implementing Rainwater Harvesting On The Austin College Campus Austin College prides itself on having an aesthetically pleasing campus. These aesthetics include multiple flowerbeds‚ trees‚ and fountains. When sitting on one of the campus lawns‚ the sound of splashing water can be heard faintly coming from the fountains‚ adding to the calm and enjoyable experience. Although these fountains look wonderful and add to the college campus’s appearance‚ they are quite expensive to run. The amount of

RAIN WATER HARVESTING AND ARTIFICIAL RECHARGE TO GROUND WATER WHAT IS RAIN WATER HARVESTING : The principle of collecting and using precipitation from a catchments surface. An old technology is gaining popularity in a new way. Rain water harvesting is enjoying a renaissance of sorts in the world‚ but it traces its history to biblical times. Extensive rain water harvesting apparatus existed 4000 years ago in the Palestine and Greece. In ancient Rome‚ residences were built with individual

easily torn in the wind. Repairs are easy to make and require little training. Ground water is contaminated. Fog harvesting technology does not need any electrical energy. Many rural areas do not have a piped supply from a reservoir. It is not foggy every day. Some of the foggiest sites are some distance from rural communities. It is not foggy every day. b) Fog harvesting may be considered to be an appropriate technology for a poor rural community because it is cheap to install and maintain

Rain water harvesting is a technique of recharge of ground water by capturing and storing rain water. This is done by constructing special water-harvesting structures like dug wells‚ percolation‚ lagoon‚ check dams etc. Rain water harvesting is not only proving useful for poor and scantly rainfall regions but also for the rich ones. The annual average rainfall in India is 1‚200 mm. It is astonishing fact that Cherrapunji (Assam)‚ the place receiving the second highest rainfall is 11‚000 mm still

Rainwater Harvesting Introduction It was very difficult to imagine few decades before that you will require to buy drinking. The use value of water was never undermined‚ but it’s about time that even its exchange value is given due importance. Fresh water today is a scarce resource‚ and it is being felt the world over. More than 2000 million people would live under conditions of high water stress by the year 2050‚ according to the UNEP (United Nations Environment Programme)‚ which warns water
