Delhi Jal Board — water overflow from tank and wastage

Address:

prashant vihar, New Delhi, Delhi, 110085

I am a resident of prashant vihar a block and there is mehta jewellers opposite lancer's school, when i pass by while strolling through street, i see water pouring and overflowing from their roof which i think is from water overflowing from water tank. It flows for hours both day and night and is happening since very long. Kindly look into the matter as soon as possible, as lot of water is getting wasted daily and action to be taken regarding this.
