Welcome To Our Web Site!

At Utility Locating Company  we perform Water Leak Detections, Pipeline Leak Testing, Gas Leak Detections, Underground Leak Detections, IR Thermal Imaging, and Utility Line Location.  We service five counties; Orange County, Riverside County, Los Angeles County, San Bernardino County and San Diego County. 

From the Spring 2002 Water Conservation News:

Leak detection is a necessary and vital component to water distribution systems worldwide. Accurate determination of the position of leaking water pipes within a supply system and subsequent repair serves to save revenue and conserve water as well as energy. Water that is lost after treatment and pressurization, but before delivery to customers, is money and energy wasted.

The methodology for conducting a leak detection survey involves a primary survey and a secondary survey. The primary survey investigates a predetermined section of the distribution system. The secondary survey pinpoints or discounts potential leakage spots identified during the primary survey. This is a very time consuming process because the survey team must make sure to systematically check every line of the supply system.

New technology is currently being produced to automate the primary portion of a leak detection survey. This technology includes a single unit comprising audible leak detection hardware coupled with a data logger, radio transmitter and extended life battery (10+ years). Multiple units are permanently installed at multiple pipe locations within the water supply system and continually monitor for sounds characteristic to pipe leakage. When a unit detects an audible reverberation indicative of leakage, the onboard radio transmitter sends a signal to an above ground receiver. The survey team now has only to drive about the survey area with the receiver to identify locations in which to return with a noise correlator for pinpointing or discounting potential leakage spots. This automated technology significantly reduces the amount of time required to conduct the primary survey. Rather than manually connecting the audio receivers to the pipes, a survey team, using this technology can simply drive about with a data receiver and record the data being transmitted from the data loggers. And, although not yet available, the incorporation of telemetry to permanently installed data loggers could eliminated the initial portion of the leak detection survey altogether.

The primary drawback to such a system is that large quantities of data loggers are necessary to accommodate a large water system. For example, Severn Trent Water reported that 173 units were necessary to properly accommodate a supply system of 2,125 properties. However, they also reported cutting their leakage rate by one half in five years. Savings of this magnitude may warrant such an investment.

Thermal Imaging Scope of Work:  Leak detection technology and equipment will be investigated using a combination of approaches including: Surveys - Surveys will be conducted on currently utilized technology both in the U.S.A. to insure that all currently used Leak detection techniques will be evaluated. Analyses - Available models and software will be used to evaluate the effectiveness of the various Leak detection methods that are identified.  We have considerable in-house software including commercially available steady-state multiphase flow models, equation of the state models and mechanistic multiphase flow models that have been developed as a result of previous Leak detection research.

About Leak Detectors

Leak detectors are used to pinpoint the source of a Leak. Gas and vapor Leaks are common in virtually any industry. In fact, it is a simple truth that anything that uses gas will Leak. The concerning factor, however, is how fast the Leak occurs, whether it be a small amount by the second or every thousand years. When the amount that is Leaking becomes a potential danger for the equipment or the health of the employees, Leak detectors are used to determine the amount and the composition of the gas being Leaked. When this is done, a corresponding action is taken to deal with the Leak accordingly.  
   
Leaks can be found via electronic, chemical and sound-sensitive technologies. Most Leak detectors are hand-held devices that are programmed to monitor specific conditions. The mobility of the Leak detectors is important because of the tight and complex networks of piping that are sometimes used to house a gas or a liquid. Most methods of Leak detection are operator dependant. Some systems, however, such as those used to detect water Leaks, are able to monitor changes in atmospheric conditions without the use of an operator. Different types of Leak detectors are used for specific duties, such as the actual gas detection at the spot of the Leak, the amount that is coming out and the type of gas. Sometimes a tracer gas like helium is used to help aid in the detection of other gases.
   
Leak detection and prevention is a crucial part of the industrial sector. Many different industries have problems with Leaks, and thus need reliable and accurate Leak detectors to fix their problems. In the medical industry, Leaks can be found in pumps, containers, fluid transfer devices and other instruments that may play a crucial role in the lives of patients. Other industries, such as the scientific and automotive, use Leak detectors on measuring equipment, water pumps, cylinder heads, calibrated volume vessels and hydraulic components. Having problems with Leaks can not only cause a system to malfunction, but could also be hazardous to health, depending on what chemical or gas is being dealt with. Because of this, Leak detectors play an important role in many fields today.  
   
Unfixed Leaks are a major source of economic loss in both the residential and industrial spheres of society. Leaking liquids and gases can damage surrounding equipment. Unchecked and un-repaired Leaks are a major health concern for people who inhabit a factory, work or home environment. Certain gasses and other chemicals can have serious consequences to individual health from even short term exposure. Water Leaks left unchecked create mold and therefore manifest many allergic responses in employees or customers exposed. The refrigeration industry is very concerned with the efficient and quality detection of Leaks, as many of the chemicals, such as the now outlawed CFC (chloroflourocarbon), can be found in many older refrigeration units still in use.
