Join Rivers(Will help both flood and drought), Sea water treatment plants, Building artificial rainwater Canals Circling cities (Pollution free), Modern housing societies to MANDATORILY harvest rain water for their own use, Encourage Gram Panchayats to build rain water harvesting plants

I feel  water  testing  facilities  in  our  country  is not  easily  accessible  to common man. Hence awareness  about  water  quality  and  conservation needs  to be popularized in our country.

जल ही जीवन है।सौ फीसदी सत्य।स्वच्छ जल पिने के लिये बड़ी मुश्किल से मिलता है जब आप के पास मिनरल वाटर खरीदने के लिए पैसा न हो। शहरों में तो लोगो के पास पैसा है वो pakaged वाटर खरीद सकते हैँ परंतु गांव तो हल बुरा है। बड़ा सवाल है भारत के गांव से गरीबी क्यों नहीं जाती।कारन है बीमारी।बीमारी दूषित जल के कारण।

Every town instead of polluting water bodies by leaving sewage water it should be recycled.
Flooding rivers should to be diverted to dry areas at least during over flow time.
Rain harvesting should be implemented seriously.
Assets which uses more than a specified quantity water should implement recycle of water.

1) linking of all rivers should be on priority, every year we suffers either due to drought or floods.
2) compulsory rain water harvesting in all buildings
3) eco toilets (minimal use of water)
4)all industries should recycle their effluents & then let it in the rivers
5) household should use minimum utensils to cook & eat

its really a big problem and can be a disaster if preventive measures will not be taken as we can see in case of Latoor and Punjab-haryana case.we need to adopt measures to recycle used water on a large scale, like a society can treat water and resupply to use it again. lets restrict water supply in areas for a day or occasionally to make them aware about its scarcity. Just like Swachta Abhiyan, we can have "jal Jagriti" but need to force it. we can't live w/out Pure water & air.

it is neccessary to supply this necccessary element which is called "water" ..its our daily using thing ,,,,but unfortunately i have to say that more than 50% of indian villages cant get pure drinking water..what a bad dream i am watching..please do something for it without shouting
