Why Private Locating
Public locates stop at the meter.
Public utility locating identifies lines maintained by utility companies. Everything past the point of service — water services, sewer laterals, septic systems, site electrical, irrigation, and communications — is privately owned and frequently undocumented.
SSP locates that infrastructure, marks it on the ground, and documents the result so your crew plans and excavates against verified field data.
Locate it. Mark it. Dig with confidence.

Why SSP
Field expertise you can build on.
- 01
Private utility specialists
Public notification covers utility-owned lines. Our entire scope is the privately owned infrastructure that sits outside those records — the lines crews actually hit.
- 02
Accurate field marking
Locates are verified on site and marked to a consistent standard so every crew reads the same ground the same way.
- 03
Response built on schedules
Most locates are scheduled within 24–48 hours because a delayed locate is a delayed excavation.
- 04
Built for contractors
Our process is shaped around real site conditions: access, staging, sequencing, and the pressure of a live schedule.
- 05
Safety as the deliverable
Damage prevention is the outcome we are paid for — for the crew, the property, and the project timeline.
