Transmission loss is a serious water problem suffered by all cities and refers to the water that is lost even before it reaches a neighborhood or business sector. Moderate estimates of transmission loss for medium to large cities can be anywhere from 10% to 25% of the available supply. Most of the reduction can be attributed to leaky underground water pipes when traced back to its source.
Due to the potential losses in resources and revenue for cities and communities, it is essential to detect underground water pipe leaks quickly and effectively. After the leak has been pinpointed, it can then be repaired through various methods.
The following is a breakdown of our basic detection and repair methods:
Water Leak Detectors are founded on the principles of sound. Professionals use these devices to survey areas and listen for anything out of the ordinary. Most modern detectors will filter out intermittent interferences like passing vehicles, pedestrian footsteps or even horns and sirens. Good indicators of leaks are usually high-pitched screeching sounds found within compromised copper piping. After a leak is found, a line device is then used to compare the frequencies of free-flowing water to the screech being heard to pinpoint the location.
There are two schools of thought when it comes to underground pipe leak repair. For some communities that are not as technologically progressive, a large tract of land must be dug to unearth the leaking section of pipe where a manual repair can be made. More modern techniques involve the use of a device known as a hydro-excavator that can fix the pipe automatically without the need to disturb the surface above the pipe.
This service is most desirable for all seasons when pipes are more vulnerable to breaking but can be performed throughout the year. Instead of waiting on ruptures, a more pro-active and cost effective approach is taken where companies comb communities in search of leaks before they happen. Because the cost of fixing leaky pipes is much greater than this routine maintenance, most municipalities have adopted this approach. The end-game for them is to reduce chances of decreased revenue with service interruption while also guaranteeing fresh water to their end-consumers.
