GPRS locates public & private utility lines as part of our services, but we do not provide state-mandated, free 811 services.

Private Utility Locating
The one-call system (811) is responsible for marking all publicly owned utilities but will not typically mark depths and will not mark any privately owned utilities. There will be at least some private utilities on almost any construction project or could even include all of the utilities on the entire site. Therefore, to receive a comprehensive locate, a private utility locating firm must be utilized to ensure that all buried utilities are located. The private locating process protects all site employees from potential line strike damages.
Facility Utility Locating & Mapping
Accurate, up to date as-built drawings and facility maps are a key to success for any construction project. The planning phase of a project relies heavily on the accuracy of the information obtained in the existing facility maps, which details the site’s underground infrastructure. With our facility mapping and modeling services, the GPRS Deliverables Department can update existing or create new as-built drawings that portray actual site conditions – including any variations, renovations, or unknown pipes.
Soil Boring & Directional Drilling Clearance
Locating underground utilities is crucial when performing services requiring directional drilling, Phase I or II investigations, environmental drilling and sampling, locating underground storage tanks, soil borings, installing monitoring wells, or site remediation. With our nationwide network of Project Managers, GPRS can mobilize to your site quickly and locate critical utilities or USTs that could conflict with your drilling or excavation area.
One Call utility Locating Services
GPRS continuously exceeds industry performance when it comes to the precision and accuracy of our utility locating services. We are equipped to partner with utility providers to manage one-call contracts or to complement 811 locates by confirming utility locations using multiple technologies or providing depths and additional information. Whether supporting locating tickets for assets such as public utilities, pipelines, and facilities or campuses on private property – GPRS is the clear choice for damage prevention.

U.S. infrastructure stats
• In the U.S., there are over 800,000 miles of public sewers and 500,000 miles of private lateral sewers connecting private property to public sewer lines. Each of these conveyance systems is susceptible to structural failure, blockages, and overflows.
• Approximately 50% of annual expenditures, in the wastewater sector, go to operation and maintenance.
• There is roughly 1 million miles of potable water piping across the country. With many of these pipes having been installed in the early mid-20th century, it is no surprise that an estimated 240,000 and counting water mains break per year.

• According to the ASCE, the total infrastructure budget needed to repair and upgrade our wastewater system is estimated at $150 billion.
• Sanitary sewer overflows are due to blockages, line breaks, sewer defects that allow water to overload the system, lapses in sewer system operation and maintenance, power failures, inadequate sewer design, and vandalism. EPA estimates that there are at least 23,000 to 75,000 sanitary sewer overflows per year.

Equipment used
Ground Penetrating Radar (GPR)
Ground penetrating radar (GPR) is a detection method that uses radio waves to identify buried or hidden components within a structure or beneath a surface. GPR has the ability to detect both metallic and non-metallic objects for a wide range of applications.
EM Locating
Electromagnetic pipe and cable locators offer another solution for locating and locating underground utilities. Made up of a transmitter and a receiver, electromagnetic locating uses the transmitter to emit a selected frequency, relying on the receiver to detect where the utilities are located.
Electromagnetic induction (EMI)
EMI is used by GPRS to detect objects such as USTs, utilities, well heads, foundations, etc. EMI compliments GPR well because it works best in the conditions that are least conducive for GPR.
push cameras
Push cameras are a smaller camera system with the ability to be manually fed into pipes smaller than 6”. Each camera is equipped with a sonde to allow for locating the pipe or locations of laterals and obstructions along with the ability to record videos.
Robotic CCTV Crawlers
Powerful and rugged, GPRS’ robotic crawlers are capable of inspecting pipes ranging from 6” to 96” in diameter. The CCTV camera crawler provides accurate views of pipeline/sewer condition and locations.
magnetometers
Magnetometers are instruments that detect magnetic fields from ferrous, metallic objects. It is typically used by GPRS to detect isolated, metallic objects such as USTs, valves, manholes, and well heads.
acoustic leak detectors
Acoustic leak detectors are made up of headphones, a microphone, an electric monitor. When combined, these detectors allow GPRS water loss specialists to non-invasively pinpoint the location of a water pipe leak by listening for distinct sounds emitting from the leak.
leak detection correlators
Leak detection correlators are electronic devices used as a leak locator to find leaks in pressurized water or gas lines.
sondes
Sondes are instrument probes that allow GPRS Project Managers to ascertain the location of underground utilities from an inaccessible location.

Utility Locating Explained
5 Faq's ABOUT GPR & UTILITY LOCATING
1. what is ground penetrating radar (GPR)?
Ground penetrating radar is a detection method which uses radio waves to identify buried or hidden components within a structure or beneath a surface. This non-destructive method uses antennas of varying strengths to transmit a signal into a surface. As the signal encounters different components within that surface, it is bounced back to a receiver at the surface. This action creates a reading which can be reviewed by experienced GPRS Project Managers in order to determine the location of utilities and other buried items.

2. how is gpr used?
Ground penetrating radar is used to identify the location of objects beneath the surface. GPRS uses this radar for utility locating and concrete scanning applications. Varying antenna strengths are used for different applications, depending on the type of material being scanned and how far down we can expect to find buried materials.

3. does gpr have any limitations
GPR is extremely effective at locating subsurface utilities and other materials, however it does have certain limitations. Ground conditions, weather, and type of material being located are just a few of the potential limiting factors. GPRS Project Managers are skilled in determining if GPR is the right choice for you project. In the event that conditions are not suitable for GPR scanning, an alternative recommendation can be made.
