That's really interesting. In the US, it is common for water distribution to be managed at the level of town or city water districts. these may purchase water from larger scale state infrastructure, but will try to source water locally via wells where possible. There are some cities where building codes require connection to the water grid for habitability, but this is much less common for unincorporated county land.
