The UK’s largest water and wastewater firm, Thames Water, has chosen Ovarro’s end-to-end service LeakNavigator to ship a three-year leakage discount contract, writes Tony Gwynne, world leakage options director at Ovarro.
Thames Water is working to realize a 20.5% discount in leakage throughout London and the Thames Valley, area to satisfy regulatory targets. Starting in January 2023, a undertaking has been underway to put in 3,450 Ovarro sensors – fashions Enigma 3-BB, Enigma 3hyQ and Enigma 3m – throughout 110 district metered areas (DMAs) inside the water community.
The sensors present a day by day call-in with leak knowledge, and simply 20 weeks into the undertaking, 788 leaks had been raised and categorised. A complete of 5.78 megalitres of water per day has been saved within the areas served by LeakNavigator.
Finish-to-end service
LeakNavigator includes superior acoustic dataloggers, cutting-edge cloud-based software program, and Ovarro’s inhouse leakage experience. With all components mixed, the service can precisely establish factors of curiosity (POIs) on behalf of water firms, alerting area technicians immediately, to allow them to head straight to web site with excessive confidence {that a} leak can be discovered, thereby decreasing the necessity for inhouse knowledge evaluation.
The LeakNavigator package deal makes use of acoustic loggers from the cutting-edge Enigma vary, that are put in following an evaluation of the focused DMA, undertaken by Ovarro’s leakage analysts. This course of establishes probably the most appropriate gear to put in, the unit numbers required, and the most effective areas for optimum effectivity. The service may apply to current Enigma logger fleets already put in.
As soon as the loggers are in operation, Ovarro’s groups undertake ongoing knowledge evaluation, sending POIs on to water firm area technicians through a cellular app. The captured knowledge, which additionally helps upkeep concentrating on, is processed, and introduced to clients in a dashboard. The package deal additionally features a full upkeep service, holding the fleet of loggers up and operating always.
Leaks discovered inside 4 days
Inside 4 working days of Thames Water’s preliminary DMAs coming on-line, the primary leaks have been handed to the sphere groups. This course of continues, with Ovarro working carefully with Thames Water’s leakage detection companions Hydrosave and PN Daly, making certain every leak is detected first time and that each one outputs are recorded in a weekly report profile for the leakage staff at Thames Water to evaluate. Quantity discount stays key to Ovarro’s efficiency and is monitored in partnership with Thames Water.
Ovarro has a novel code offered for Thames Water’s leaks, which will be tracked on-line. All leaks are energetic till they’re repaired, sustaining management of the outputs from every technician and the methodology used for the detection exercise.
Ovarro takes full possession of the info evaluation and leak detection course of, working in collaboration with water firms and their companions, with results-driven accountability. The service permits leakage groups to be extra environment friendly, by discovering leaks on blended pipe supplies. Ovarro’s focus is to realize shoppers’ leakage targets and in the end safe future water provides.
Ovarro is constant to work with Thames Water to cut back leakage in elements of north and south London and the Thames Valley and count on to see much more success within the weeks and months forward.
Optimistic outcomes
Shane Gloster, senior technique & transformation supervisor at Thames Water stated: “Water is a valuable useful resource, which is why we’re centered on driving leakage down and dedicated to assembly formidable leakage targets. A key pillar of our lately launched Leakage Transformation Programme units out to enhance our potential to seek out and repair the proper leaks, sooner.
“We’re utilising knowledge and implementing new instruments to make knowledgeable choices, prioritise leaks and scale back restore occasions. Ovarro’s LeakNavigator is supporting this objective and we’re impressed with the optimistic outcomes it’s delivering.”
