Qonnectis saves Glan Hafren NHS Trust £60,000
The implementation of a water leakage detection initiative by the NHS trust Energy Management team at County Hospital, Griffithstown, has saved the Gwent Healthcare NHS Trust over £60,000 on its annual water bill and will receive an additional £60,000 in sewerage rebates from its water supplier over the last two years. The water meter monitoring service provided by Qonnectis plc involved the use of a Qonnectis universal meter logger and internet based water meter monitoring and analysis on myMeter.info web site powered by Qonnectis.

Local NHS managers at County Hospital, Griffithstown had long suspected that there may have been a water leak on the site as the water bills appeared excessive compared to hospitals of a similar size. Having just completed a successful Qonnectis water leakage detection project at Tonteg Hospital for the Pontypridd NHS Trust, Qonnectis was asked to install a system and provide web services to track water usage at the County Hospital.

A Qonnectis iStaQ-LG GSM-enabled universal logger was installed next to the site water meter at the County Hospital and continuously posted water usage trends to the Qonnectis myMeter.info web site.

When Griffithstown County Hospital NHS engineer, John Jukes, analysed the results on the website he discovered that there was a very high level of water consumption during the early hours of the morning – a period when water demand should have been low.

It soon became apparent that there was a leak of 4 cubic metres per hour on the site and trial holes were excavated at positions where the leak was thought to be. Because of the high number of unrecorded service tees off the site’s water main, the leak initially proved difficult to locate. When it was eventually found and repaired, water demand on the site was reduced by a factor of 10!



Wayne Churches, Glan Hafren NHS Trust’s Energy Manager (pictured using myMeter.info website by Qonnectis) was delighted with the results of the leakage detection initiative. “Following these excellent results we are now looking at deploying the Qonnectis internet-enabled utility metering technology at all of our major sites throughout the Trust.”

Qonnectis Director, Percy Albuquerque commented “Qonnectis water and energy users utilising the myMeter.info web based metering services have benefited enormously from being able to analyse and identify abnormal utility consumption, correct excessive usage or leakage and provide daily reporting to facilities management on what is becoming a major cost in operating expense in most businesses as a result of the recent rises in water and energy prices. In most cases the payback period on deploying Qonnectis’s myMeter.info utility consumption monitoring and analysis is less than two years, in this case of Griffithstown, payback was less than one month with immediate positive cash flow benefit from the second month onwards in reduced water charges.”
