How to Rapidly Reduce NRW Levels

To deal with NRW effectively, it is crucial to know where the losses are occurring and how much water is lost. The most common approach to tackle water loss involves establishing District Metered Areas (DMAs) to conduct flow balancing, where the difference between the volume of water entering the zone and the actual consumption is identified. From this, the level of NRW and leakage can be determined. 

The next step is to pinpoint the precise location of water loss. This is commonly performed by skilled engineers or field technicians using a range of technologies that require recurring inspections of a given zone. Acoustic technology is one of the prevailing methods that determine the location of water loss.

With strong fundamentals in acoustic technology, Echologics developed its products and systems with intensive research and development to further advance existing acoustic technology. This enables Echologics’ offering to work effectively across all pipe materials – including plastic and asbestos cement – and to operate on both transmission and distribution mains. The most recent innovation, the EchoShore® platform, is a cloud-based leak detection solution. The EchoShore® platform is the result of significant global experience in the development and applications of acoustic technology.

The Echoshore® platform combines an established leak detection software with advanced cloud-based data analytics to locate leaks as they form in the infrastructure network. Unlike other cloud-based platforms, the EchoShore® technology can locate small leaks with an accuracy of +/-2m on transmission mains and with even greater accuracy on distribution mains. Being non-invasive and non-disruptive to operations, the technology can be installed on all pipe material and sizes from 50mm to 3,000mm in diameter. 

In Malaysia, working with local engineering partners, Echologics provided a cost-effective solution of the EchoShore®-M leak detection technology to monitor long distances of transmission main. The monitoring approach rapidly surveyed over 3,000 km of various type of pipeline with diameters ranging from 300 to 2,200 mm. This NRW program additionally enabled locally based technicians with no prior leak detection experience to train within weeks to install the technology, analyze data, and pinpoint leaks independently. In total of 267 leaks were discovered delivering an outcome saving of 26.31 million liters per day on non-revenue water loss.
