State guide
North Dakota
North Dakota DEQ's Drinking Water Program defines a service line broadly enough to include both the public and private portions and tells systems to inventory both sides. In the city pages reviewed, Fargo follows the common main-to-curb-stop public split, while Bismarck and Grand Forks have local rules or programs that can differ from that simple model.

- Who usually owns the water service line
- Often yes, as Fargo places the split at the curb stop, but North Dakota cities do not use one single rule: Bismarck states all service-line fixtures off the main are the owner's property, and Grand Forks code places repair expense from the main to the meter on the landowner while the city retains control.

- Permits for repair or replacement
- North Dakota administrative rules say any plumbing installation requiring inspection must have a plumbing installation certificate returned with fees prior to commencement of work; ND DEQ also says public-water projects must meet applicable local and other state requirements.
- Assistance programs
- State pages describe inventory assistance for water systems through the Drinking Water State Revolving Fund, while local private-side help was found in Grand Forks funding and Bismarck's Service Line Repair Fund and lead-line assessment option.

What to do next
- Ask your city utility where its ownership point is; in North Dakota it may be the curb stop, or local ordinance may place more of the line on the owner.
- If your property is in Grand Forks or Bismarck, check whether you qualify for city lead-line funding or reimbursement before hiring a contractor.
- Before work starts, confirm whether a plumbing installation certificate or local permit is required and whether the project touches public right-of-way or public-water facilities.
