Retail buildout downtown - we needed private utilities located inside a tight easement. They marked every line, gave us a PDF for the permit set, and saved us a week.
Sofia N.Project Manager, Austin CBD · Austin, TXPrivate Utility Locating · May 2025 - 5.0
Running a 300-ft irrigation feed through a Cedar Park subdivision - they located every private utility we needed and marked the yard cleanly. Made the bore go smooth.
ChrisIrrigation Contractor, Cedar Park · Cedar Park, TXPrivate Utility Locating - 5.0
Needed potholes on a Dell campus tie-in. Crew was OSHA-tight, minimal spoil, and the utility depths matched the as-builts to the inch.
KarenSite Super, Round Rock · Round Rock, TXHydro-Excavation & Potholing - 5.0
New build in Travisso, developer's line locate was garbage. CSC came out, found two abandoned laterals nobody knew about, saved us a whole day of guessing.

We were tying into a 12-inch water main in Sun City. CSC daylighted the utility and gave us a report the engineer signed off on same day.

Sub-slab leak nobody could pinpoint at our office building. Their locator narrowed it to a 3-ft window and we cut one tile instead of half the breakroom floor.

Line Locating FAQ
Frequently asked
Isn't 811 free? Why pay for private locating?
811 only marks public utilities up to the meter or curb. Everything customer-side - irrigation, private power, low-voltage, gas from meter to building - is on the owner to locate. That's the work we handle.
Do you use ground-penetrating radar?
For non-metallic lines and hard-to-detect utilities, yes. Standard sweeps are electromagnetic; GPR is available when the site calls for it.
Can you locate abandoned lines?
Sometimes - it depends on the material and whether we can induce a signal. We've had strong success with abandoned lines across Central Texas.
What utilities can you actually detect?
Metallic pipes and cables (water, gas, electric, telecom, steel and copper), tracer-wired PVC, and - with GPR - non-metallic pipe, conduit and buried structures. We identify what's detectable during the site walk and flag anything that requires potholing to verify.
How accurate are your locate marks?
Horizontal accuracy is typically within a few inches for detectable lines; depth estimates are within roughly 10% under normal conditions. Where verified depth is critical - near gas, fiber or shallow electric - we recommend pairing the locate with hydro-potholing for SUE Level A confirmation.
Do you provide a written report or just paint marks?
Both. Standard delivery is paint and flag marks on the ground plus a site sketch, utility type, estimated depth and confidence level. Engineering-grade deliverables and CAD overlays are available for design and SUE projects on request.
How quickly can you get out for a locate?
Most private locate requests inside the Austin metro are scheduled within 1-3 business days. Same-day and next-morning slots are available when a crew is standing by waiting to dig - call and we'll get you on the schedule.
How much does private utility locating cost?
Priced by site size, number of lines and accessibility. Bundled pricing is available with hydro-potholing when verified depth is required. Send an address and a scope description for a firm quote.
How do I know your line locating findings will hold up with an owner or reviewer?
Every observation is coded to NASSCO PACP standards and delivered with the HD video, footage marks, and a written summary, so the owner's rep, engineer, or municipal reviewer can check the call against the footage instead of taking our word for it. NASSCO/PACP certified operators, 25+ years in Central Texas pipe work, and full commercial and municipal insurance with COIs issued the same day.
What do commercial clients say about your line locating work?
The reviews on this page come from general contractors, property managers, and municipal staff who hired us for line locating, averaging 5.0 out of 5 across 16 published reviews. Each one names the role and the type of job so you can judge whether it matches your site.
Do you provide line locating in Austin and the surrounding cities?
Yes. Utility Line Locating is one of our core commercial services across Austin and the metro, including Round Rock, Cedar Park, Georgetown, Pflugerville, Leander. We run out of Cedar Park and cover roughly a 100 mile radius of Austin, so crews reach most Travis, Williamson, and Hays County sites the same week and often the same day for emergencies.
How fast can a line locating crew mobilize to an Austin site?
Most Austin jobs are scheduled within one to three business days, with emergency mobilization available for active backups or shutdowns. Austin is about 20 miles from our yard, and neighboring cities such as Austin, Round Rock, Cedar Park are typically same-day reachable. Call (737) 618-0219 and we will confirm a window before you commit.
Can you handle traffic control and permits for line locating in Austin rights-of-way?
Yes. For work in Austin streets, alleys, and public easements we coordinate traffic control, provide certificates of insurance, and document the work so the City reviewer, the GC, or the owner's engineer can accept it. The same process applies in Austin, Round Rock, Cedar Park, Georgetown and other Central Texas jurisdictions we work in weekly.
Will your line locating reports be accepted by Central Texas municipalities?
Yes. Deliverables are NASSCO PACP coded with HD video, footage marks, still images, and a written summary, which is the format Austin area public works departments, engineers, and general contractors expect. We have delivered accepted reports across Austin, Round Rock, Cedar Park, Georgetown, Pflugerville and the wider Central Texas market.
