The Menace called Water Tanker service in Vignan Nagar, Bangalore

Some parts of Bangalore does not have BBMP water supply facility and hence public generally depends upon bore well water. Some areas also ground water is too scarce and hence they have to depend upon tankers to get water. I stay in Vignan nagar area and its just 5 kms from Baghmane Tech park, one of the prominent IT park in Bangalore. Everyday I usually face couple of water tankers in my way to office and vice versa. Some of the water tankers does not have registration number available and they drive so rash and negligently I usually get late to office becuase of these tankers. I am not sure whether the owner of these tankers i.e. water suppliers have the necessary permit to supply waters. In my area, there are at least two suppliers and they supply waters 24/7. Because of these tankers the road condition is really very bad. One of my neighbour ground water supply is very less because because the his bore well was not too deep and he is going to buy the water from a supplier who is just couple of flat away. Yesterday, my father told me that there were two more bore well drilling is going on, that means because they sell waters 24/7, the ground water level will be slowly slowly depleting. Not sure, what can I do. My neighbour told me that these water suppliers are powerful peoples and if you complain about them, you will be sufferer. The problem is they keep on selling water and the general public is suffering because of these activities. Most of the areas in Kagdaspura have the same problem. Why cannt govt stop these suppliers from incessantly using ground water and instead BBMP should supply water to these areas.
I would request govt to look into this matter
