The utilities 811 does not draw — and who finds them
A short explainer for contractors and municipal procurement teams landing cold. It covers what private utilities are, why 811 coverage stops at the meter, and why a NULCA-certified locator using multi-method geophysics is what closes that gap on a real site.
The assets on the property-owner side of the meter
Private utilities are the lines and equipment that sit behind the public utility meter or right-of-way boundary — owned by the property owner, the campus, the facility, or the private system operator. They are not on 811's member-utility lists, so a normal locate ticket does not reach them.
- Water service laterals from the meter to the building
- Fire-service laterals, hydrant leads, and private fire loops
- Site power feeders, duct banks, and pad-mount equipment
- Gas and LP lines downstream of the meter
- Sanitary laterals, grease lines, and cleanouts
- Storm drains, catch basins, and private detention piping
- Low-voltage / communications, site fiber, and security conduit
- Site lighting, branch circuits, and amenity power
- Irrigation systems, control wiring, and valve manifolds
- Geo-exchange (geothermal) loops and grout-hold piping
- Private chilled water, steam, and district-energy loops
- Abandoned or unknown-service lines left from prior work
811 stops at the meter — the rest is your problem
811 is a notification service for its member utilities. A ticket routes to each member that has assets in the right-of-way, and each member locates the public-side portion of its system — typically up to the meter or point-of-service. Anything beyond that boundary, plus non-member utilities, abandoned lines, and post-meter service, is outside the scope of the response.
Private property lines
On-site distribution that runs inside the property boundary is owned and maintained by the property owner — 811 will not mark it.
Non-member utilities
Any utility that has not joined the 811 notification system is invisible to a standard locate ticket. Site lighting, private water, irrigation, and low-voltage contractors are examples.
Post-meter service and downstream lines
The service lateral usually stops being a member-utility responsibility at the meter or point-of-service. Everything on the customer side is on the property owner.
Abandoned and unknown lines
Left in place from prior construction, demolished buildings, or undocumented tie-ins — 811 only marks what its records show. The rest has to be field-verified.
Industry damage data puts the annual cost of utility strikes in the United States in the tens of billions of dollars, with private-side assets accounting for a large share of those incidents. Closing the gap above the 811 boundary is where a private utility locator earns the fee.
Certification plus multi-method geophysics is what closes the gap
NULCA — the National Utility Locating Contractors Association — is the industry-recognized body for the locating profession, and its Locator Certification Program is the baseline that procurement language defaults to. Certification is the floor; multi-method geophysics is what actually reads the site.
- NULCA certification is the contractor-side baseline — a uniform standard for how a locator reads a ticket, marks a site, and reports the result.
- EML (electromagnetic induction) and RF (radio-frequency) methods read conductive and energized targets — the workhorse pair on most sites.
- GPR (ground-penetrating radar) reads non-conductive targets — PVC, HDPE, fiber, voids, and unknown structures — that the other two methods miss.
- ASCE 38 ties the combination to horizontal + vertical confidence tiers so a scope document holds the locator to a defined outcome.
- Multi-method is what makes the deliverable defensible on a hospital, campus, or municipal scope — single-method marks are not.
SureTrace engagements pair NULCA-certified field crews with that three-method detection sweep, mapped to ASCE 38 quality levels with a defined deliverable set that closes each project on the same terms. Procurement language that points at a NULCA-certified locator backed by multi-method geophysics is the starting point most new engagements begin from.
