AUTOMATION OF WATER DISTRIBUTION SYSTEM

Please help me by providing necessary concept regarding fully automatic water supply with no water wastage mechanism

Too vague.

Is it water supply to a whole city, a small community of apartment blocks, or a single house?

No one can give meaningful suggestions unless the scale is known.

Thanks sir,it is within the small residential campus of 1 sq kilometer only

Is the water supply to buildings in the campus laid by some municipal agency or is it designed and laid by the community?

this is because a lot of water wastage occurs (especially in Bangalore) because of faulty layout or damage by unauthorized activity leading to breakages.

Please see if you get some conservation ideas from these sites. It may help you to generate a design brief that can be discussed here with CEans.
