Nothing is free, even water, it takes processing and filtering of water and pumping it etc...it costs money....but the citizens have decided that they need or want the government to handle it, and they pitch in with taxes, to pay for it....and with water bills.
When I lived in Massachusetts, the town I lived in sold off or leased the municipal water system and a private company came in to run it...the whole state's city and town waters systems were moving towards private companies owning or running them.

All rights are NOT written....
Inalienable rights, or unalienable rights, are rights that are not written but assumed to be given, by the Creator.
Our governments have taken the stance that they should provide the city communities with clean water....meaning they are the ones organizing the pumping in and filtering of water and there was always a town pump where the citizens could get clean drinking water. If a citizen wanted it pumped to their house, the citizen had to pay to have the pipes from their house to be connected to the pipes of the main city water system, same with sewer pipes from their house.... but in the direct city and town areas, there are rules and regs in place that prevent these home owners from being able to drill their own wells and put in their own leech fields...mainly the fact that your water well has to be in the LEAST, 100 feet from any leech field....and town homes and city homes are too compact and close together to be able to follow the sanitary rules and regs....they HAVE TO HAVE city run water and sewerage.
We owned a rural home with our own well and leech field, and the town expanded and rural became more town like and the town added city sewer and city water...and if we wanted to go on to this city system, WE HAD TO PAY for the connection of the pipes from our house to the city lines...
All municipalities provide drinking water...the citizens pay for such water with a "water bill" that pays for the filtering and purification and maintenance of the water facility.
I live in a small town, that is really spread over several miles with only 1500 people....the downtown area, has city water, but the rest of us that are rural...3/4's of us townsmen, had to pay to dig our own wells and pump our own water. We still pay our town taxes that pay for these few people in the town center to have city water and city sewer, while we pay to have our leech fields put in...
But truly, if looked at closer, our taxes are not necessarily paying for these town center people to have city water, because they do have to pay their water and sewerage bill, and their homes are valued much higher than ours in the rural areas, so they are paying higher property taxes than we are for the same sized home because it is valued higher.
Yes, the gvt has the right to regulate water use, if it is the one providing the water for its citizens, and even if it is not, when it comes to public waterways....
I have a friend who owns a small inn in a ski resort area...he has his own well and pumps his own water to provide water for the Inn guests....just a mile down the road from him, a big nationwide hotel corporation put in a large hotel, and it too pumped it's own water for its guests...well it turns out, that this large hotel was drawing water from the same underground stream as my friends small inn, and his inn lost their water....there was no longer enough water to supply the small Inn they had owned for over 20 years....
So, he had to sue the large hotel corporation for the water that he once had for his business....and this hotel firm had to pay for a large water cistern to be added to his Inn, and the monthly water bill to get it filled.
the courts are government....they are at least minimally involved with the distribution of water.
