system for the subdivision shall meet the standards for such jurisdiction
or the standards of the State Department of Natural Resources and
Environmental Control, or it may be an independent source of supply
approved by the County Engineer and the State Department of Natural
Resources and Environmental Control, in which case some acceptable
arrangement shall be made for its ownership and operation. The method
of ownership and operation shall be approved by the County Attorney

supply shall be provided with a water supply and distribution system
and fire hydrants meeting nationally recognized standards which have
