DMA and large diameter metering – Some guiding principles - Mikal Willmott / Andy Godley https://www.youtube.com/watch?v=2XHGPOJ7XqQ In many water systems DMAs are key to active leakage control. Night lines are key to prioritising which DMA’s to target and when. The accuracy of a night line is largely dependent on the accuracy of the [...]
Supporting Water Loss Management Practices using a Mobile DMA Testing Unit - Bradley Jenks https://www.youtube.com/watch?v=PGiZYSeGpNQ&t=21s This presentation will introduce a field-based water loss management program in Ontario (Canada) involving the development and deployment of a mobile testing unit to monitor flows, with and without pressure reduction, into district metered areas (DMAs). The project is [...]
Pipe Assessment and Leak Detection based on Continuous Acoustic Monitoring Oded Fruchtman https://www.youtube.com/watch?v=mFi3xbdLbG4&t=36s The presentation will show a new Pipe Condition Assessment concept which is based on big data analytics of past pipe repairs and leak detection. The presentation will include a live demo of the Pipe Condition Assessment project Aquarius performed at [...]
The Use of Frontier Analysis to Assess the Technical Rigor of Water Loss PI's - Alan Wyatt https://www.youtube.com/watch?v=Wv1pNr1wAQ8 The American Water Works Association (AWWA) has developed and disseminated advanced methods and performance indicators for assessing and reducing water losses in North America, based in large part on the methods and indicators developed [...]
The knowledge of leak noise and Active Leakage Control case studies in China - York Yuxi Wang https://www.youtube.com/watch?v=vWg54CJElDo Although water leak detection activities in China mainland started as early as in 1970s, the awareness of ‘Active Leakage Control’ hasn’t been fully understood till entering the millennium. In fact, we as the ‘IWA China [...]
Making our old pipes new again! A European Perspective - Joseph Finn https://www.youtube.com/watch?v=J0MoxMzOIaM Failure of ageing and deteriorated water mains is a threat to the structural integrity of a water supply network, causing adverse effects such as service disruptions and property damage. However, just because something is old, it doesn’t mean it [...]
Failure of ageing and deteriorated water mains is a threat to the structural integrity of a water supply network, causing adverse effects such as service disruptions, revenue loss, and property damage. However, just because something is old, doesn’t mean it needs replacing. Knowing your current asset health will reveal maintenance and capacity issues before they become problematic, enabling targeted planning both financially and operationally. This presentation is the second in a three-part series from Mueller showcasing how a staged approach to pipeline asset management using machine learning and non-invasive IOT technologies is being adopted by utilities around the world. Case studies will be shared highlighting the successful implementation of this approach in the North America region. Maintaining and upgrading North America’s water pipelines is a pressing infrastructure challenge. The AWWA estimates, that a 1 trillion-dollar investment in water pipelines is required over the next 25 years. Part 1 of this series was presented on May 8th covering the Asia Pacific region and Part 3 will showcase how this approach has been adapted in Europe and will be presented as part of this IWA series of Webinars on May 13th, 2020.

Case studies will be shared highlighting the successful implementation of this approach in the Asia Pacific region, which has led to informed intervention decisions being made to reduce NRW and extend asset life. Parts 2 and 3 of this series will showcase how this approach has been adapted in North America and Europe and will be presented as part of this IWA series of Webinars on the 11th and 13th May 2020 respectively.
Tooling for Leakage detection support in systems with DMAs - Zdenek Sviak https://www.youtube.com/watch?v=-hHj6EM6kpU Description The webinar will concentrate on the general needs, approaches and methods in Leakage detection support over the DMAs. The requirements on the supporting tools are given by complexity and volume of the input data, compliance with the WU organization, workflow [...]
Topic NRW in Small Systems – DMAs for PVC - Chris Leauber https://www.youtube.com/watch?v=ogL4hVgwHf4 Description The IWA/AWWA Free Water Audit Software determined that the vast quantity and value of NRW for the Water & Wastewater Authority of Wilson County, Tennessee, USA is real losses. This utility case study will focus on how the Authority uses [...]
