EM Locator
Our water loss specialists have the equipment and expertise to locate your leak and provide insights into your water distribution system. GPRS utilizes a variety of industry-leading equipment and methods, including acoustic leak detectors, leak noise correlators, video pipe inspection, ground penetrating radar, and electromagnetic locating.
Wastewater Treatment
Excavating, drilling, or saw cutting near wastewater treatment facilities can be challenging due to the presence of critical utilities and underground assets that must be protected during construction. GPRS offers solutions such as Utility Locating, Video Pipe Inspection, Leak Detection, and the SIM process to prevent damage and ensure safety.
Water Distribution & Collection
Water and sewer pipelines often span long distances, encountering numerous utility crossings. When installing new water and sewer pipes, it's essential to locate underground utilities. GPRS can also perform utility locating before excavation for repairs or replacements of existing water or sewer lines.
///LEAK APPLICATIONS
Active Leak Detection
Your Project Manager will flag and paint their findings directly on the surface so that you and your team know where it is and is not safe to dig. GPRS also uses a global positioning system (GPS) to collect data points of findings used to generate the maps and models you need to Intelligently Visualize The Built World®.
Routine Water Loss Surveys
By the time a leak becomes apparent, you’re already risking damage to your infrastructure and thousands of dollars in repairs and non-revenue water loss (NRW). Regular water loss surveys help you find leaks before they become emergencies.
Assesses pressurized subsurface water systems
Pinpoints and marks out any leaks detected
Allows for planning, targeted repair, and maintenance with minimal excavation
Fire Suppression System Checks
Along with your regular sprinkler, and vane (flow), pressure switch and fire pump checks, your facility should undergo an annual water flow check. It is vital to the safety of your facility and to remain compliant. Plus, system leaks can lose thousands of gallons of water before you notice, leading to large budget overruns. GPRS can locate leaks in any pressurized water line to make sure your system is effective when you need it.

Valve Exercising
When water system valves stiffen, they can impact flow and pressure with corrosion, rust, and mineral deposits. If left in a static position too long, stiffened valves can become inoperable or incompletely shut off. Exercising your valves regularly can avoid stiffening and the issues it can cause.
GPRS can provide valve exercising services to keep every part of your pressurized water system intact.

///EQUIPMENT & TOOLS
Every GPRS Project Manager is an expert in applying multiple technologies to your site to achieve a comprehensive and 99.8%+ accurate utility locate. Because avoiding a utility strike and keeping your people safe isn’t just about what equipment we use, it’s about the knowledge and experience of the people using it.
Acoustic Leak Detection
GPRS Project Managers are experts in acoustic leak detection for pressurized water lines. They use specialized microphones, headphones, and control units, and complementary technologies to pinpoint water leaks by listening to amplified sound waves in a wide variety of pipe materials.
Ground Penetrating Radar
The tool our company was founded on, GPR, in concert with other complementary technologies, is used to identify buried objects and underground utilities. Our Project Managers provide 99.8% accurate field-verified utility maps, delivered via SiteMap®, PDF & .KMZ files to all GPRS customers.
Leak Detection Correlators
These algorithm-powered tools utilize radio waves via a dual sensor system to process and digitally display leak vibrations that correlate to potential pressurized water system leaks. It is used in conjunction with acoustic devices to provide pinpoint leak detection in water and fire suppression infrastructure.
EM Locating
Electromagnetic (EM) locators are preferred by One Call contractors to locate public utility lines. GPRS utilizes them with GPR and other technologies as part of our Subsurface Investigation Methodology process to detect live AC power or radio signals along conductive utilities.
///Case Study
Accurate Utility Maps & Leak Detection Save City $125,000
TASK:
Perform routine water loss survey for Town of
New Castle, New York, to determine where and how they were losing water.
Project Application:
Town officials wanted to identify where and how non-revenue water (NRW) loss was occurring within the community’s system.
The Bottom Line:
GPRS Leak Detection saves town 125,000 gallons of water per day
.svg)
Problem
The client, a municipality in New York, was experiencing a significant amount of Non-Revenue Water (NRW) loss due to leaks along their 110-mile system
There were no instances of surface water to indicate areas of concern
The municipality did not have a precise calculation of the gallons per day (GPD) they were losing
.svg)
Solution
Utilizing acoustic leak detection, and leak detection correlators, GPRS Project Manager evaluated the entire system including hydrants, in-line main valves, and service valves
Identified 18 leaks, four of which were costing the town over 10,000 gallons per day each in NRW loss
.svg)
Benefits
New Castle saved an estimated 125,000 GPD after resolving the detected leaks
Town was able to dig only where they needed to rather than excavating large segments of the water system to inspect for leaks
Improved service performance and reduced risk of service interruptions

///ROUTINE WATER LOSS SURVEYS
Recommended for all water systems
Leak detection Project Manager utilizes acoustic leak detection and leak noise correlators to evaluate areas of concern
Find leaks even when no water has surfaced
Your underground water infrastructure is a complex maze – constructed over decades or centuries with pipes of various materials – layered and ever-changing. Forgotten or abandoned pipes, unexpected lead service lines, and defects large and small cannot be seen (or heard) without the proper tools and training. That’s why GPRS highly recommends routine Water Loss Surveys to update your existing condition documentation, find new defects and leaks to better maintain your system, protect your water, and your community.
///Case Study
Efficient Leak Detection & Mapping Strategies for Property Infrastructure
ASK:
Pinpoint any leaks on the property’s fire loop and domestic water systems within 200 ft. of the location of proposed new construction. 2: Conduct a full site leak survey and map all underground water lines on site to pinpoint any additional water line leaks
The Bottom Line:
GPRS identified a significant 230,000-gallon-per-month leak in the main water system and an 86.4 million gallon per month leak in the fire suppression system during our survey. This discovery resulted in substantial cost savings for the company, amounting to hundreds of thousands of dollars.
Problem
Client needed clearance around a proposed slab location for new construction & reported massive water bills that led the Project Manager to explore further.
Solution
The initial investigation found no leaks in the proposed construction area. However, the additional full site water loss survey found seven leaks, responsible for at least 87 MILLION GALLONS in non-revenue water (NRW) loss per month. By creating updated digital documentation via SiteMap®, Merson can better manage their systems to avoid additional NRW loss.
Benefits
Mersen had clearance for their new construction with no fear of hitting a water line
GPRS’ discovered a total of seven leaks among the main water and fire suppression systems
Pinpoint leak detection allowed Mersen to stem approximately 87 million gallons of non-revenue water loss per month & save hundreds of thousands of dollars
///WHAT IS NON-REVENUE Water
Non-Revenue Water (NRW) is the water lost in a distribution system before reaching the end user/customer.
The American Water Works Association (AWWA) shifted terminology from “unaccounted-for water” to non-revenue water (NRW) because water loss is always accounted for; the difference is whether the water was consumed for benefit/profit or lost to waste.
At least two trillion gallons of water – enough to fill up 3.28 million Olympic-sized swimming pools – is lost from underground water pipes every year.
The American Society of Civil Engineers (ASCE) estimates more than $2 billion is lost annually to aging and defective U.S. plumbing and water treatment infrastructure.
