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

Zoology Connect Quizzes Chapter1 Your friend releases a pair of goldfish from an aquarium into a pond. The fish survive long enough to produce many young. Returning to the pond after several years‚ you find that only drab olive-brown offspring remain from the original brightly colored golden parents. Select any factors listed below that would have promoted the survival of olive-brown fish over the brightly colored variety. The fish in the wild spent most of their energy finding food and

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. Also‚ repairs can be fixed easily by little experienced people. The main advantage of the project is that
