How to Find a Water Leak

Our highly trained engineers at L.D.S. Leak Detection Specialists Ltd. will choose the approriate testing and inspection process specifically chosen to suit your home or commercial business to find the leak.

Our engineers at L.D.S. carry all the latest technology in leakage detection. We have listed the main Leak detection methods and equipment below. Inspection cameras. Protimeter mms damp meter survey kits, pressure gauges both hydraulic and digital and salts diagnostic kits also form part of the L.D.S. engineers equipment.

Leak Detection Methods to Find A Leak

Acoustics
Acoustic profiling uses ground and pipe sensitive microphones to enhance the sound of the leak. This method can help in pinpointing precise leak location.

Correlation
Is a way of finding and pinpointing leaks in water pipes. A leak in a pipe under pressure creates noise that travels through the pipe walls, the surrounding ground and along the contents of the pipe. Correlators are a very accurate sound testing device which are used to identify the acoustic frequency caused when a pipe is leaking. The correlator uses two identical sensors located along the pipe to calculate the leek location by logging the signal delay, sensor distance and the sound velocity.

Tracer Gas
The trace gas, a safe mixture of hydrogen and nitrogen, is introduced into the pipe with the suspected leak. The gas, is the lightest in the atmosphere and is made up of of small molecules. The gas will exit at the leak and make its way to the surface where it is detected using gas sensitive detection pobes.

Thermal Imaging
Thermography is the use of an infrared imaging and measurement camera to see and measure thermal energy emitted from an object. Thermography cameras can identify problem areas that can’t be seen with the naked eye, detecting hidden water leaks. The infrared inspection camera can detect not only hidden water leaks and their origin, but also moisture that cannot be physically reached with moisture meters. Read more

Pipe, Cable and Metal Detection and Tracing
Often the exact position of pipes and cables is unknown due to innacurate or non existant network plans. In order to carry out precise water leak detection and to avoid damage to utilities and operators during excavations, it is essential to know the precise position of all services. We use high performance equipment which can locate and trace buried pipes and cables.

Network Monitoring with Noise Loggers
Noise Loggers are used for early detection of leaks in water supply networks.The longer it takes to identify that a network is leaking the more revenue is lost and the greater the loss of precious water resources. In addition to the more conventional methods of leak detection the installation of permanent noise loggers has proved to be a cost effective tool in early identification of water loss. By permanently monitoring sections of the system, which have previously been proven leak free, it will alert you when a potential leak does develop. Read more .

Geological Engineer Careers

Geological Engineers

Geological engineering involves geology, civil engineering, and fields such as mining, forestry and geography. These engineers apply earth sciences to human problems. Specialty areas include geotechnical site studies of rock and soil slope stability for projects; environmental studies and planning for construction sites; groundwater studies; hazard investigations; and finding fossil fuel and mineral deposits.

Geological engineers investigate things that are part of or are made to be part of the earth, including roads, mines and quarries, dams, petroleum production, railways, building projects, pipelines, and forestry operations.

They engineer clean-up and environmental assessments where pollution occurs. They survey for minerals and drinking water; they search for building material resources, and they map potential landslides and earthquakes. The variety in this field is enormous.

What do They do?

Many of these specialists consult for engineering or environmental firms. Many are employed by highway departments, environmental protection agencies, forest services, and hydro operations.

Construction industries depend on geological engineers to assure the stability of rock and soil foundations for tunnels, bridges, and highrises. Foundations must withstand earthquakes, landslides, and all other phenomena which effect the ground, including permafrost, swamps and bogs.

Geological engineers find better ways to build and manage landfills. They find safer ways to dispose of toxic chemicals and garbage, and to manage sewage. They plan excavations and design tunnels.

Transportation infrastructures depend on geological engineers to determine strong terrain and safe pathways for airports, railways, highways, and even pipelines.

These engineers are heavily employed in energy fields, exploring for more natural resources (oil, gas, uranium, tar sands, geothermal and coal). They develop ways to mine hard-to-access resources, and in the least polluting manner. They are responsible for the safety of pits, reservoirs and mining facilities, guarding against earthquake damage and environmental risks—even for nuclear reactors.

Groundwater is another geological engineering specialty. Industries and farms need reliable water sources, sometimes requiring dams or well drilling. Water supply to hydroelectric dams is regulated by these engineers; they design dikes and they work at preventing shoreline erosion.

Ore and other metallic mineral deposits (lead, zinc, iron, nickel, copper) are essential to transportation and construction industries. Geological engineers discover new sources of minerals, as present supplies diminish.

Geological Engineer Schools

Becoming a Geological Engineer

A B.S. in geological engineering gives students in-depth studies in the humanities, economics, and social science. Graduates have the communications skills to be effective and responsible in meeting the social needs of their field. A B.S. typically is a 4-year course of study and involves laboratory work.

Courses include geology, structural geology, marine paleontology, paleoecology, igneous and metamorphic petrology, mineralogy and optical mineralogy.

Advanced degrees are needed to pursue careers as environmental, petroleum and mining geologists.

The senior-year capstone experience allows students to explore the technical facets of their specialties as well as the business of engineering—teamwork, project management, communications, ethics, and intellectual property. Teams experience opportunities with real, client-based projects that tackle problems they are likely to encounter on the job.

Geological Engineer Employment Outlook

According to the U.S. Bureau of Labor and Statistics. Mining and geological engineering positions are expected to increase by 10 percent between 2010 and 2020 for those with bachelor’s degrees. This occupation does not require the numbers of professionals that many other professions employ, but a growth of 10 percent is about average for all occupations.

Typical Geological Engineer Salary

Geological and mining engineering and sciences have a median salary of $84,300, and the top 10 percent earn $136,800 (BSL ).

Career Advancement Opportunities

Government agencies, both federal and state, employ geological engineers to develop and enforce environmental standards, and to conduct research. Post-graduate degrees open opportunities for higher salaries, research and teaching.

Is This the Right Career for You?

If you were a child who often picked up “special” rocks, or watched fascinated as creeks followed their course underground and out again, or as springs bubbled from the ground… If you tunneled in snow banks, built forts, footbridges or sandcastles… you were literally toying with geological engineering.

Still, before pursuing geological engineering specifically, it is a good idea to find your niche discipline—structural, environmental, or geotechnical engineering, for example.

Career-related experience is available long before graduation, and will help you better understand any field of study. Through co-op programs, students gain experience interning in their field of study, and some are paid.

Internships are another great way to put a toe in the water. Interns perform a broad range of laboratory procedures; they use computers to figure size distributions and generate plots and statistics; they do field work at sea, and make geophysical surveys. If these kinds of activities appeal to the explorer or builder in you, that’s a good sign.
