Detecting and repairing leaks ...

Detecting and repairing leaks is one of the main components of water conservation.

The sonic leak-detection equipment’s are most important

Traditionally, water main leaks were not detected until the problem announced itself in the form of flooded basements or water welling up from cracks in the street. although small losses often will go completely unnoticed. Even though monitoring water usage section by section narrows down the search considerably, city employees then must painstakingly trace kilometres of pipeline buried under the streets while using special equipment to “listen” from aboveground for the tell-tale acoustic signs of a rupture. While old-fashioned and time-consuming, this method is both reliable and accurate—leaks can be traced to within approximately one meter by a trained operator.

Signs of underground leaks include:

• Unusually wet spots in landscaped areas and/or water pooling on the ground surface.

• An area that is green, moldy, soft, or mossy surrounded by drier conditions.

 • A notable drop in water pressure/flow volume.

• A sudden problem with rusty water or dirt or air in the water supply (there are other causes for this besides a leak).

 • A portion of an irrigated area is suddenly brown/dead/dying when it used to be thriving (water pressure is too low to enable distant heads to pop up properly).

 • Heaving or cracking of paved areas.

• Sink holes or potholes.

• Uneven floor grade or leaning of a structure.

 • Unexplained sudden increase in water use, consistently high water use, or water use that has been climbing at a fairly steady rate for several billing cycles.
