Delhi Development Authority [DDA] — Wastage of water

It has come to my notice that almost daily a lot of water is being wasted in dda park just in front of my house, i.e in west vinod nagar patparganj, beside to swati appartment
a gardener is there but he rather than giving water to the plants/trees he waste that water which i have been noticing since a week now
please take an action against it for the cause of the nation
Thank You.
