United Utilities Trunk Main Trial
10/15/2021
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
10/15/2021
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.

Leakage Management: Meeting The Challenge
9/30/2021
Anglian Water has reduced leakage by 20% since 2010 and has committed to a further 23% reduction by 2025. Overwhelmingly, customers have told Anglian Water that leakage is a high priority and that they want to see it reduced to well below the Economic Level of Leakage (ELL).
The aim was to develop, own and utilize a system that enables cost-effective, smart, real-time leakage monitoring at an individual asset level for Anglian Water's entire network. The team was faced with a multitude of challenging conditions; the sites consisted of a large range of materials, including but not limited to Cast Iron, Ductile Iron, Asbestos Cement, MDPE, and PVC.

How To Get Acoustic Leak Detection For The Price Of An AMI Meter
9/13/2021
Whatever number a utility estimates as its non-revenue-water (NRW) loss rate — 20 percent, 30 percent, or more — the willingness to address it is often inversely proportional to the cost of doing so. Now, leak detection options that include acoustic monitoring as a built-in feature of residential water meter replacement are cutting the costs and complexity of identifying NRW losses and recapturing lost revenues.
