By WLRandA Ltd (UK) and the JOAT Group of Companies (South Africa)

Thursday 15 and Friday 16 February 2018
At Tsogo Sun Elangeni Hotel, Durban

A review of NRW Problems, Practical Concepts and Workable Solutions
Speakers will include:

Allan Lambert, Water Loss Research & Analysis Ltd, UK
Professor Kobus van Zyl, University of Cape Town
Mark Shepherd, JOAT Consulting, Durban

Overview of Workshop

The water supply problems experienced in South Africa during drought periods in the last few years have common features with problems experienced in other countries. Drawing on both local and international data sources and experiences, the speakers will facilitate discussions and exchanges of views in three main topic areas, relating to management problems in both the drawdown and recovery phases of drought events.

Some parts of the workshop will be retrospective, reinforcing the basic 4 components of managing leakage – pressure management, speed and quality of repairs, active leakage control and infrastructure management – together with water balance, night flow and fit for purpose performance indicators. Other parts will be forward looking, providing value added advice, latest concepts and fast track calculations for practitioners, particularly in relation to understanding the many influences of pressure.

Workshop Objectives

The objective of the workshop is to maximise the learning and interactive experience with several of the foremost international experts on water leakage and pressure management theory. Apart from traditional presentations, delegates will be part of a true skills transfer and knowledge-building experience through talks, case studies, worked examples, demonstrations and multi-media presentations where they can learn from, question and meaningfully engage with the world’s leading academics and practitioners in the fields of Non-Revenue Water, leakage management and pressure/leakage relationships. Break-out sessions and interactive booths will be integral part of the learning experience to maximise knowledge sharing.

Formats of the individual sessions will be varied, some with several speakers giving short presentations in the same session topic. Delegates are encouraged to contribute questions, which may be spoken, or written and contributed anonymously if preferred.

Morning Session: Problem Areas
• The water balance – how to put it together
• Assessing NRW and NRW components from Water Balance
• Fit for Purpose Performance Indicators
Morning Session: Workable Solutions
• Avoiding intermittent supply
• Targeting Pressure Management Options
• Targeting unreported leaks using Night Flows
• Setting Targets and Reporting Progress
Afternoon Session: Basic Concepts for Leakage Practitioners
• How pressure transients and maximum pressures influence burst frequency

• Basic component analysis of real losses
Afternoon Session: Summary: Questions and Discussion
Early Evening: Informal ‘Meet the Speakers’:,
• Buffet, demonstrations; enter your own data into free basic small spreadsheets.

Workshop Takeaways

Each delegate will receive:

• information on free website access to key papers, presentations and Guidance Notes
• spreadsheets for ‘fast track’ calculations of recent advances in pressure management analysis.
• personalised Portfolio of Training Evidence

Application has been made for each delegate to receive 2 CPD points for attending the course

Allan Lambert has 55 years’ experience in the UK and international water industry, split in almost equal parts between Water Resources/Hydrology, and Non-Revenue Water management, with experience in more than 40 countries. A Past President of the British Hydrological Society and special advisor on water resources and leakage to the UK Government during the 1995-1996 drought, he developed Component Analysis (Background and Bursts Estimates) when he was Technical Secretary to the UK National Leakage Control Initiative in 1992-1994. He chaired the 1st IWA Water Loss Task Force (1995-1999) which developed the Best Practice IWA Water Balance and Performance Indicators. A Fellow of the IWA, he has been researching and applying the many benefits of pressure management for over 20 years, after being inspired by John May’s ideas in 1994. As a leading international authority in leakage management, over the last 4 years he has developed the LEAKSsuite website to disseminate his knowledge, free-to-all, to over 20,000 users in 175 countries. Readers of Water & Wastewater International magazine voted Allan in the top 25 for global thought leadership in the water industry in 2016 and 2017.

Kobus van Zyl is a professor in the Department of Civil Engineering at the University of Cape Town. He has been involved in research on the behaviour of leaks in distribution systems for more than 15 years using a range of techniques that include hydraulic, FEM and CFD modelling, mechanics theory, laboratory studies and field work. He collaborates closely with leakage practitioners and has published 11 peer-reviewed papers on the behaviour and modelling of leakage in distribution systems. He is a professional engineer, an associate editor of the ASCE Journal of Water Resources Planning and Management and a member of the Editorial Board of the Urban Water Journal. He currently chairs the ASCE Environmental and Water Resources Institute’s standing committee on Water Distribution Systems Analysis


Mark Shepherd is a registered professional Civil Engineer and Director of the JOAT Group of Companies, part of EOH Holdings. He has 24 years experience, of which 18 have been dedicated to the field of water leakage management and Non-Revenue Water reduction. He is a member of the IWA, AWWA and a Fellow of WISA and has both worked and presented papers and workshops in his field of speciality around the world, having worked mainly in developing countries. He has specialised in pressure:leakage relationships as well as assisting water companies from an institutional strengthening perspective to ensure sustainability of water efficiency interventions. He is actively engaged in assisting both the University of Cape Town and WLR&A in promoting the dissemination of specialist knowledge within the water sector.
