Industry Trusted Leak Detection Experts
GPRS's Leak Detection service is used to help municipalities, utilities, and industrial facilities maintain safe, efficient water distribution within a domestic supply network and fire protection systems.

Severe leaks can cause significant problems underground by eroding soil, causing voids, and compromising the integrity of buildings without any water ever coming to the surface. GPRS can quickly pinpoint a known leak when a problem is identified or can proactively search for leaks along a domestic water or fire system for a municipality or facility.

But how common is water loss? Researchers at the American Water Works Association estimated that we collectively lose more than two trillion gallons of water due to leaks within the current infrastructure. That is enough to submerge Manhattan 300 feet underwater. However, leak detection and routine water loss inspections can mitigate this loss.

GPRS specializes in all types of leak detection, including municipal, industrial, and residential. Our Leak Detection Specialists have the equipment to locate your leak and the expertise to provide many other insights into your water distribution system.

How Are Leaks Detected?
GPRS Leak Detection Specialists utilize various technologies and decades of expertise to pinpoint any type of leak, from a major water main break to a small crack in a service pipe. Leak locations are verified with correlating software in real-time. In addition, our leak detection services can be integrated with other services such as Valve Exercising, infrastructure mapping, and utility locating to improve efficiencies and help customers achieve a fuller understanding of underground infrastructure.

GPRS uses two primary technologies for our Leak Detection services:
  • Acoustic Leak Detection
    Acoustic leak detection uses sophisticated ground microphones to listen for leaks coming from subsurface pipes. Our Leak Detection Specialists are thoroughly trained to home in on leaking pipes' specific sounds and frequencies.

    Pipes made of metal, such as cast iron/ductile mains, smaller copper service lines, and steel pipes, transmit water leak sounds over longer distances than those made of PVC or asbestos-cement pipes. Accordingly, it is critical to consider the pipe material and the size. Small diameter pipes are more likely to transmit more sound than large diameter pipes, regardless of their material. Large diameter pipes transmit lower frequency sounds than small diameter pipes.

  • Leak Noise Correlators
    Leak Detection Correlators (also called leak noise correlators) are specialized electronic devices that leak detection service companies like us use to locate leaks in water lines and water pipes quickly and accurately. They use sensors placed on both sides of the pipe, and these sensors send information back and forth between each over via radio. An automated process identifies each suspected leak location and displays it on the main control unit in its in response to the detected anomalies. The processing unit then compares this data with mathematical algorithms designed for the specific noise profiles of the pipe material being tested, determining where the leak is coming from between each sensor’s location.

    Our Leak Detection Specialists map out the leaks using the data from the Leak Detection Correlators and then more accurately pinpoint the leaks using their acoustic leak detection equipment.

    GPRS also includes Valve Exercising and Routine Water Loss Inspections in addition to our Leak Detection services.

Valve Exercising
Valve Exercising is a preventative measure program to ensure water valves function efficiently. GPRS's team of skilled technicians identifies each gate valve using GPS-enabled technology and records the precise number of turns required for maximum efficiency. This valuable information is compiled into a database that allows future leaks to be quickly located and repaired, reducing the risk of service disruption during leak detection services. Then each valve box is cleaned, and valves are carefully exercised to prevent buildup of tuberculation and other deposits that can render valves inoperable or lead to tight shutoffs.

Routine Water Loss Inspection
Schedule a routine water loss inspection and save potentially thousands of dollars in lost revenue.

Many factors cause leaks in water systems. They include corrosion, high system pressure, damage during construction, improper installation, frost or freezing, failing or damaged joints, and ground shifting or settling. Routine water loss survey programs can generate substantial benefits, including limiting non-revenue water, reducing property damage, and providing updated and accurate maps of water infrastructure.

Cost, subpar water performance, environmental impact, and property damages caused by water loss are entirely avoidable. Often people will wait until there is an acute water loss problem before scheduling a leak detection; and by that point, a business or municipality could have potentially lost thousands of dollars in water loss. Water loss is an irrecoverable loss.  

Regular water loss inspections can prevent unnecessary water loss and save businesses and municipalities money.

Why Should You Choose GPRS for Leak Detection?
With over 250,000 projects completed, GPRS combines top-of-the-line technology and equipment with Project Managers who are SIM trained and qualified. This means that not only do they have the best tools available but they have been trained and mentored to assess every situation possible, placing safety above all.

If you have been searching for a water leak detection company that you can rely on, the GPRS team is here to help! So don't delay; schedule a routine water loss inspection to make sure that your water lines are secure.
