Updates on Applying FAVAD Concept

Hydraulic Analysis and Fast-Track Applications for Practitioners

Outcomes of collaborative research by the University of Cape Town and several international leakage practitioners, to improve both theoretical understanding and practical application of the Fixed and Variable Area Discharges (FAVAD) concept for pressure:leak flow relationships, will be publicly available by mid-September. A common basic philosophy has been used to model hydraulic laboratory studies of both leakage and intrusion flows through leak openings in pipe samples, with fast-track analysis and prediction applications for practitioners using pressure management to reduce leakage in water distribution systems.

Pressure Transient Awareness

Pressure transients – seeing is believing

Hidden transients cause leaks, raise repair costs,

reduce asset life

Would you like to see what a pressure transient looks like – not just as a graph, but as a visible reality? Read on to access a startling media clip of transients generated in an above ground mains test rig, and then consider what damage may be done to underground distribution systems by pressure transients. International leakage management specialists who contributed to this blog are very well aware of the adverse effects of such events. However, many Utilities do not routinely take short-period pressure measurements to check for the presence of transients; or they may consider that if transients exist, they probably do not significantly influence leakage, burst frequency and infrastructure life.

LeaksSuite Website Outreach

Progress in January to March 2017 and new initiatives

The major upgrade of the LEAKSSuite website in Feb 2013 created a free information source for international concepts and management of Non-Revenue Water, Apparent Losses, Leakage and Pressure. During Jan-March 2017, User numbers rose by 2,200 (12%) to 19,900 from 181 countries, and number of Page Views reached 112,800. The overview of the website statistics to date, near the end of this Blog, shows User numbers by Google Geographical region and country; key topics of User interest are shown below. Analysis of trends in this data is used to identify new initiatives which are likely to be of greatest interest and benefit to Users.

The creators of this website hoped to achieve 20,000 users, the same number of Liverpool supporters who watch from Anfield’s famous Spion Kop. It has taken us only 4 years to achieve this number. We hope that those of you who use the website, wherever you are in the world, WILL NEVER WALK ALONE with LeaksSuite available at a click to help you with your NRW management.

Managing NRW – Roof Storage Tanks & Intermittent Supply

Tuesday, December 6th, 2016

Masterclass for Aguas de Saltillo with

international experts

Nov 2016, Llandudno

Some of the concepts and practical approaches now available for managing NRW become more difficult to apply when water is delivered to consumers through large roof storage tanks, rather than by direct pressure. Where supply is also intermittent, the problems of quantifying and reducing NRW are then compounded by excessive frequencies of leaks and bursts, damage to the distribution system and impairment of meters, and reduction of asset life. The recommended solution is to move to a 24/7 policy of continuous supply, but this is easier said than done. However, some Utility systems (Malta), and Malta and Cyprus case studies in with roof storage tanks have achieved continuous supply with ILIs close to, or even below, 2.0

Interpreting Leakage in England & Wales

England & Wales Water Company Leakage

Rises – or Falls?

 

Consumer Council for Water Report confuses interpretation of

leakage statistics

Engineers and Scientists are often accused of failing to communicate effectively by using terms that are ‘hard to understand’ for media and the public. Some organisations and individuals believe they can simplify and improve the published message, but instead corrupt the output, by failing to recognise the difference between ‘evidence’ and ‘interpretation’. If, in public relations, ‘perception is reality’ then what responsibility should publishers of reports accept for confusing, rather than informing, on key issues?
