I have a well. It costs about $6000.00. Now that's a lot of monthly water bills. And I have to pay for electricity to pump the water. I paid about 1000.00 for the filter system. I need to pay that much or more for a water softener. But I hate the feeling of softened water on my skin when I take a shower. Maintenance and supplies for those are expensive.
But city water isn't normally from a well. Some cities transport water long distances. Even if it was from a well water, it would probably still go through some water management system and might even have to be purified. Thus the cost of water management plants and personnel.
In addition to a water plant. It takes a lot of pipe to make water available in a city.
So do manufacturers who make pipe...make it for free? Should the companies who must purchase very expensive heavy equipment and pay skilled labor to lay the pipe do it for free?
The list goes on about everything it takes to get water to homes or dwellings.
So who is to pay for all of the above labor, equipment, services..etc? Water is probably the most profound issue facing humanity today. It's all about da money. One day probably all water will have to be pumped and processed from oceans.
