Water and sewer connections; mandatory in Powhatan County.

Adds Powhatan County and Smyth County to the list of counties that may require connection to their water and sewer systems by owners of property that can be served by the systems if the property, at the time of installation of such public system, or at a future time, does not have a then-existing, correctable, or replaceable domestic supply or source of potable water and a then-existing, correctable, or replaceable system for the disposal of sewage adequate to prevent the contraction or spread of infectious, contagious, and dangerous diseases. Smyth County is also added to those counties with authority to assume the obligations of a public service authority under the same terms and conditions as applicable to the public service authority.
