They are extending Water lines from the Johnston County System over the border into Wake (on Cornwallis Rd) to service a new subdivision. Now I could understand if they were combining the water systems. But what did the developer do to get the residents of Johnston County to subsidize growth in Wake Co ?
Wake County does not have a County Water system. Municipalities like Garner or Raleigh has city water, but there is no County water for Wake County so they would not be combining systems.
