Water supplier tanker's source

As mentioned in my previous post, many water supplier tankers supplying to Hiranandani and/or Powai area get their water filled from near the Shipping Corporation compound. I had wondered (and still wonder) whether the water is somehow taken from the Powai lake (see the post).

A photograph is now available. The Powai lake is on the opposite side of the road (photography of the Powai lake is prohibited - it is probably covered under some Security Act or the other). On the right side of the photo, note the helmet seller (hawker!). The greenery behind the water tanker seems to be part of the Shipping Corporation of India compound. But I may be mistaken - maybe that is part of some other estate (but unlikely given the size of the Shipping Corporation Compound).

Please note that I am not saying this is illegal. This may be very much a legal activity, but one needs to probe further. My contention is that Powai lake levels dipped far more this year's summer than in the past.
