I think what you can do practically is to check the source of incoming water to your construction site. If it's supplied in a tanker, go to the source and conduct an inspection. Is the water being filled in the tanker from a bore well or any other polluted source?
Apart from the above, there are efforts from the Ministry of Water Resources related to water. The Draft National Water Framework Bill, 2016, and Model Bill for Conservation, Protection, Regulation, and Management of Groundwater, 2016 have been released for public comments. If you are interested, please see the documents attached.
We can hope that in the coming days, the BOCW and Factory Rules will also address this issue.
