• How Can We Take Climate Change Into Account When Designing Water & Wastewater Treatment Facilities?

    Scientists have long predicted that one of the impacts of climate change would be an increase in the frequency of extreme weather events and rising sea levels across the world. We are already seeing it happen across the USA and the world.

  • Fairlie District Deploy Noise Loggers In New Zealand

    Installation was completed by Farilie District Council, a rural water authority located in the central South Island of New Zealand. With a number of water supplies in the South Canterbury region, they required the latest digital noise correlation and signal coherence frequency analysis processing software. The Enigma solution was chosen to overcome challenges such as limited recoding and process capabilities.

  • Leak Detection In Nantes, France

    The water network management team in Nantes, France is responsible for maintaining supply from a highly complex system of underground water supply pipes. Constant road traffic and restricted access make monitoring, troubleshooting, and upgrading the water network exceptionally challenging. The La Dopea (Direction des Opérateurs Publics de l'Eau et de l'Assainissement) leakage team was tasked with assessing the supply to one particular area of the Nantes Metropole area. Initial investigations indicated substantial losses, but traditional leakage detection methods had failed to identify where these were. The business challenge was identifying and preventing these leaks.

  • United Utilities Trunk Main Trial

    United Utilities supplies water to 3 million homes and 200,000 businesses in North West England. Within the Winscales and Scilly Banks service reservoir zones where the trial was to take place, local United Utilities NCI / NIA had previously split the main and quantified losses of 4 liters/sec and 2 liters/sec in the respective halves. Leak detection on trunk mains using correlation techniques has always had potentially limited success for reasons of poor sound propagation and scarcity of accessible fittings. The business challenge was to exceed these limitations, improve efficiency and reduce leakage.

  • Abilene “Phocus” On Their Non-Revenue Water Program

    The State of Texas and the region around Abilene in particular has been experiencing an ongoing drought. Abilene takes the region’s need for adequate water supplies seriously and has been analyzing the short-term water needs (5-10years) as well as the long-term water needs (+50years) for its service area. The ongoing drought had pulled the three primary water supply reservoirs for the region down to extremely low levels. In the autumn of 2014: Lake OH Ivie was at 15% capacity; Hubbard Creek Reservoir was at 16% capacity; Lake Fort Phantom Hill was at 32% capacity.

  • Leak Location On 11 Mains In The UK

    Leak location on large diameter mains is difficult because the pipe becomes more elastic as the ratio of pipe wall thickness to diameter increases. This results in more rapid absorption of leak energy into the pipe material, with resultant attenuation as distance from the leak increases.


For years, global water utilities have battled the lack of precise leak locations, inability to determine leak severities in industry-accepted metrics like GPM, and numerous false-positive readings from acoustic data loggers, correlators, listening sticks, and sensors. The purpose of this webinar will be to re-set how leaks can be more accurately found and expressed in GPM to support CAPEX decisions and long-term pipeline reliability & sustainability. Instead of listening (acoustically), seeing (visually), or smelling (helium tracing), attendees will learn how machine-intelligent technology can automatically measure the size of holes, by combining Ohms’ Law, plus Torricelli’s Law.

Get to know Ovarro and how our solutions support hundreds of applications world-wide.

Ovarro's Wez Little and Alan Cunningham got together to discuss the level of water wastage (currently 3 billion liters per day in the UK!) and how innovations from companies like Ovarro are supporting water companies in finding and eliminating leakage.

How many international models are heading up companies in the water and wastewater industry? As the youngest environmental engineer in New Zealand, Zac MacFarlane is bringing a unique appreciation for aesthetic design to visually showcase the installations and success stories of Clemens Water Engineering and the Pure Group.
