Start with the boundary published for the serving utility
Norman public side
The City of Norman defines the public side as the portion from the water main to the meter, including the meter, and states that the City maintains it. [1]
Norman private side
Norman defines the private side as the portion from the meter to the home or building and assigns that side to the homeowner. The City also states that replacement of water-service pipe on private property is at the property owner's expense. [1]
Oklahoma City public side
Oklahoma City states that its public side runs from the water main to the meter and includes both the meter and a city-owned pigtail that extends less than two feet beyond the meter. The City says that pigtail is typically 18 to 24 inches long. [2]
Oklahoma City private side
Oklahoma City defines the private side as the remaining line from the end of the public pigtail to the point where the line enters the home or building, plus indoor plumbing. The property owner is responsible for that private side. [2]
What to do when a service-line leak is suspected
- Confirm whether Norman, Oklahoma City, another municipality, a rural water district, or a private well serves the address.
- Report the condition to that utility and ask it to confirm how its published boundary applies to the account and configuration. Norman and Oklahoma City publish different boundary details. [1] [2]
- Record visible water, pressure changes, utility findings, and the location of any private shutoff without opening a meter box or operating utility-controlled equipment.
- If private repair is indicated, arrange a plumbing evaluation that distinguishes the leaking segment and plans access, isolation, material, testing, and restoration.
- Submit the locate request at least three business days before excavation and confirm every notified facility operator has responded. OKIE811 explains that private utilities, often between a meter and building, may not be marked through the public process. [3]
Useful clues and unsafe assumptions
Useful evidence
Do not assume
The serving utility's published boundary and its address-specific explanation. [1] [2]
The meter is the same legal boundary in both cities. Oklahoma City's published public side extends through a short pigtail beyond the meter.
Meter movement after authorized fixtures are confirmed off.
The meter proves the exact underground leak location.
Utility and private locate markings plus diagnostic findings.
A wet spot is directly above the failed pipe.
A marked proposed excavation area and site-specific safety plan.
A shallow trench or hand digging is free of utility and collapse risk. Excavation hazards still require planning. [4]
A private repair scope should state
- The utility-confirmed responsibility boundary and the segment being repaired.
- How the suspected location was established and what uncertainty remains.
- Expected excavation, boring, slab, landscape, paving, and restoration boundaries.
- Pipe material, route, valves, connections, testing, inspection, and utility coordination.
- How a different field condition will be documented and approved before the scope expands.
Questions for the serving utility
- Which water utility and account serve the exact address and meter under review?
- Which equipment and service segment does the utility inspect, maintain, or require the customer to repair for this configuration?
- Will the utility perform a field check, meter test, shutoff, or restoration step before private work begins?
- What reference number, written finding, or contact should be included in the private plumber's work order?
- If the visible water is outside the stated boundary, which public works, street, or emergency contact should receive the report?
