Leak Detection

When it became apparent that fixing the leaks is imperative, we looked at tools that could help. There are many different types of devices available for leak detection, ranging from acoustical to H₂ tracer gas leak detectors, water leak correlators, lift-and-shift, and permanent radio noise loggers.

Currenly our leak detection toolkit consists of the following:

• constantly being on the lookout for visual leak signs (running water, wet spots that never dry)
• regular monitoring of water tank levels and volume of water passing through the treatment plant
• a listening device (acoustical leak detection)
• pressure testing devices

Pressure Testing

Pressure testing is used for testing for leaks past a service connection. A gauge is fixed to the exterior water faucet and monitored to see if pressure drops within a certain timeframe.

Acoustical Water Leak Detection

We purchased an acoustical water leak detector which our water operators use late at night, when water use is very low.

Water leak sounds vary depending on the following factors:

• – The severity of the leak or damage to the pipe
• – Location of the pipe
• – Water pressure
• – Pipe installation or construction
• – Depth of the pipe location
• – Soil type
• – Surface cover

How do Acoustic Detectors Work?

Acoustic detectors are made of the following components:

• – Headphones
• – Microphone
• – Electronic monitor
• – Acoustic listening stick

Acoustic detectors work by connecting a stopper to the suspected damaged pipe. The stopper will then open and close the valve to create a rhythmic pulsation that will then be picked up by an acoustic listening stick. The microphone of the detector is then placed directly above the buried pipes to listen for the sound of the leak(s). Wherever the sound is the loudest, that is where the leak is located.  

Why is it Recommended?

The use of acoustic leak detectors is highly recommended because it eliminates the need to dig out the ground or remove any structures just to check the pipes physically. This takes a lot of effort and requires repairs and replacements afterwards. Physically locating leaks takes time and is done through trial and error. Using acoustic detectors eliminates the hassles of inspecting and checking the lines physically. This saves you time and money. It is also environmentally friendly because there is no need to dig up and damage the surroundings. Acoustic leak detection is cost-effective and efficient. It cuts the work time in half, maybe even more. It is one of the most effective ways to spot and locate a water leak.  

Advantages of Acoustic Leak Detection

• – It saves time and effort.
• – It eliminates the need to remove concrete or dig up the ground.
• – It is cost-effective.
• – Acoustic leak detectors are very accurate.
• – It does not cause any damage to property.
• – It allows suspected leaks to be identified immediately.
