Advantages Of Water Harvesting

These tanks has proved very effective in high rainfall areas, where they need to store large amount of fresh water. Its a low cost alternative for water harvesting containers and can be easily prepared by semi skilled labours. It can be moulded in any desired shape and durability is around 25 years with little maintenance and it is very cost effective hence suitable for Indian villagers to store rain water.

Australian floodplain wetlands are sites of high biodiversity that depend on flows from rivers. Dams, diversions and river management have reduced flooding to these wetlands, altering their ecology, and causing the death or poor health of aquatic biota. Four floodplain wetlands (Barmah-Millewa Forest and Moira Marshes,

Chowilla floodplain,

About 17 km3 for industrial and 56km3 are for municipal purposes. We all know that pond and earthen embankments could support in harvesting and storage of water. Traditinal methods are very easy to construct and very cost effective irrespective of modern methods even though many of traditional water harvesting methods cannot be implemented in urban areas but they are best suited for rural areas. Traditional methods of water harvesting can become more effective if scientific attempts are combine. Nothing is better than something Government should provide funding and facilitate them and encourage Traditional methods in their restricted domain. For example bamboo irrigation and drip irrigation have same use that is irrigating soil drop by drop hence increasing the moisture in soil around its roots. Drip irrigation is more effective and surely better than bamboo irrigation but cost of implantation of bamboo irrigation is very less compare to drip irrigation even though its life is less as compared to tackle irrigation. In today 's time drip irrigation is one of the best way of irrigating soil but we can alter the fact its channels are made from PVC pipes which are plastic waste whereas Bamboo irrigation channels are made from bamboo which after decomposition use as raw material in preparing fertilizers. Tanks, johads are replace with ferro cement tanks, roof top rain water harvesting in urban areas. Katta are barrier constructed to resist or minimize the flow of water which can be build in small scale it replacement is massive barrier called dam which can do same work in better way and more effectively though construction cost is much higher than the traditional way of constructing barrier to conserve rain water still traditional methods are good in small scale but to fulfil everlasting consumption of
