Ancient water supply network

Previous Next

Do you know how leakages are found in water supply networks? The leakages can be located, for example, by filming or by using a device that listens to the sounds from the leakage. How these options sound like in a world, in which a fridge can send you a picture and a text message that you are about to run out of milk?

Evaluating the condition of the network by filming is slow, and work made by humans. A video camera is put into the pipe, which then records, and the record is watched and evaluated by a professional. Evaluating the condition of the network from record can be challenging. One cannot evaluate large area at one time. Moreover, pipes are often dark by color, which can make the work more difficult. The method is expensive.

Locating the leakage by sound is not always reliable because of false alarms. The device listens to the network, and reports from abnormal sounds, and alarms. The material of the pipe, amount of traffic, size of the leakage, and device's level of sensitivity, affect the performance of the device. Plastic pipes are hard to listen to, and the device does not necessarily detect small leakages.

At the moment, the most effective method to locate the leakages might be biosensors. Biosensors detect the leaks on the street or in the premises, and call about it. The disadvantage of the method is the slowness, because the leakage is detected only when it has already caused a visible problem. The biosensor is a human.

Thus, Econet’s remotely readable water meter could be a solution, which brings the evaluation of the network and locating leakages to present.

Econet is creating a remote water meter, which measures the pressure and flow real-time. With the information it is possible to calculate real-time where even small leakages are.
