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

Storage tank Transfer tank Process: It is a batch process divided into three stages‚ Initial stage: The sump is filled with half of the backwash water of DMF‚ ACF and half of RO reject water through filtration sump‚ and this water is pumped to raw water tank. Second stage: The sump is filled RO reject water‚ and this water is pumped to raw water tank. Final stage: The remaining portion of the raw water tank is filled with raw water. From the above three stages the raw water tank is filled

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

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
