It also highlights the rationale behind the structure of a new tariff regime, which is aimed at fostering the long-term financial sustainability of the Armenian Water and Sewerage Company (AWSC), and summarizes main lessons learned.
Three separate water leaks located over a distance of 826m using the AQUASCAN TM2 - Case Study
Introduction Locating leaks on large diameter water mains can be very difficult due to poor sound propagation and increased distances between fittings that can be used to perform correlations from. For a correlator to highlight a potential leak each sensor must be able to receive the signal from that leak. Once a correlation is highlighted it is then down to the software and the user of the software to accurately pinpoint the potential leak as the noise created by the leak may not be heard from the surface due...
Yorkshire Water uses AQUASCAN TM2 for trunk main leak detection - Case Study
Introduction After initial meetings about suspected leakage and NRW losses with Craig Needham and Piotr Kozeil from Yorkshire Water a trial was arranged to use the GUTERMANN AQUASCAN TM2 correlator. An initial location on an 18” Cast Iron trunk main was identified from Longwood Service Reservoir feeding four large DMAs. Other leak detection methods had previously been carried out with a point of interest which were to be compared and followed up with the AQUASCAN TM2. Challenge The Cast Iron main had...

KEEPING UP WITH TRENCH WORKS – CONNECTING PEOPLE
When we are not connected we feel isolated. And some remote places are really isolated from the rest of the world. Because there are no roads to get to the districts where secluded people live, no gas pipelines to carry methane for central heating, no water mains, no oil pipelines, no telephone lines and no fiber optics. Today being connected means that it’s a lot easier. It's easier to communicate, easier to travel, easier to transport things. And easier for business. Establishing connections brings wealth.
Fisantekraal Municipal Waste Water Works, Durbanville, South Africa - Case Study
The city’s newest treatment works opened in Fisantekraal in 2012. It uses state of the art ultraviolet disinfection and is geared as a ‘zero discharge’ plant, as the treated water is piped to customers for irrigation purposes.BBR was awarded the odour control contract in 2012.Performance data illustrates that H2S removal is in excess of 99%, coupled with complete removal of other odours.BBR treat the main component H2S as follows: The PH of the water is raised to 9.5 to enable fast and total...
