Delhi Jal Board — water pilferage in society

Address:

New Delhi, Delhi, 110075

Suryodaya apartments, dwarka sector 12, pocket 8, opposite to raddison blu hotel.
The water tanks lack auto stop or a basic alarm sensing the water level in tank this leads to motors pumping water in the already overflowing tanks.
I have personally approached some flats and requested them to take care but my actions have gone in vain.
Every morning thousands of liter of water gets wasted due to the above reasons. Please take immediate and strict action on this and suggest if i/ society can contribute in any way.
