What this page can identify
The guide represents common Canal Winchester mailing ZIPs—43110—and uses Columbus Public Water System, Pickerington Public Water System, or another local system with an address-confirmed PWSID as the current research starting point.
What still requires the address
The bill, service address, current report and property plumbing determine whether the starting point applies. ZIPs, city limits and county lines do not define one water-service boundary.
