Allan Lambert

  wwi lead logo 1   Over 50 years experience in water management

Working with international experts for global and local solutions

Allan Lambert has had a long-standing interest in practical applied research throughout his professional career of over 50 years in the Water Industry. He was appointed to the IWA Fellows program in 2011 ‘in recognition of his extraordinary achievements’. In 2016 readers of Water and Wastewater International magazine voted Allan 8th out of 25 ‘best of the best’ global thought leaders in international water/wastewater industries.

Academic qualifications include  B.Eng. 1st Honours in Civil Engineering, a Travelling Scholarship as top student in 1961, an M.Eng in open channel hydraulics (University of Liverpool); and a postgraduate Diploma in Hydrology with Distinction in 1964 (University of Newcastle upon Tyne). He is a Fellow of CIWEM and a Past-President of the British Hydrological Society.

From 1962 to 1984 Allan worked in hydrology and water resources with UK River Boards (Mersey & Weaver), River Authorities (Usk, Dee & Clwyd) and Water Authorities (Northumbrian, Welsh). He conceived and developed the real-time flood forecasting ISO-function model and supported the World Meteorological Office on flood warning projects in China, Pakistan, Thailand, MAllan at Llanrhos, North Wales UKexico and Dominican Republic. Allan chaired the statutory Consultative Committee which set Directions for management of the multi-purpose Dee River Regulation; conceived and implemented the Clwyd Augmentation and Abstraction scheme with the Water Resources Board; and developed practical reservoir control rule and Operational Yield concepts which were applied in the UK after the 1995/96 drought.

In 1984, following the formation of multi-purpose Divisions in Welsh Water, he moved to Water Supply Operations and became strongly interested in improving the understanding of distribution leakage management. As Welsh Water representative, he was Technical Secretary of the National Leakage Control Initiative (1992-4), designed the England/Wales Water Balance, developed the concept of Real Losses Component Analysis (Bursts and Background Estimates), and was principal author of several of the ‘Managing Leakage’ reports (UK, 1994) . He was Specialist Adviser on Water Resources and Leakage to the House of Commons Environment Committee during the 1995-6 drought.

In 1995 Allan become an independent consultant, and chaired the 1st IWA Water Losses Task Force (1995-1999) which developed the IWA international best practice Water Balance and KPIs, including the Infrastructure Leakage Index (ILI) which is increasingly used internationally for performance comparisons. He has written numerous technical papers, and was principal author of the Financial Times report on Managing Water Losses – Economic and Technical Issues (1998), the IWA International Report on Water Losses (2001), and a principal advisor to the EU Reference document ‘Good Practices on Leakage Management WFD CIS WD PoM’ (2015). He was a member of the IWA Water Loss Specialist Group Senior Management Committee until late 2014 when he stood down due to limitations on travelling internationally.

Allan continues to contribute to the work of the IWA Water Loss Specialist Group on a wide range of topics, with particular interests in performance indicators, economic intervention for active leakage control, and the many beneficial effects of pressure management. He has acted as mentor to many people who are now international specialists in leakage management, and continues to try to assist anyone with a genuine interest in following in their footsteps – either through personal communication, or (for example) by ILMSS Ltd and WLRandA Ltd sponsoring the Early Career Water Loss Symposium at IWA Water Loss Europe 2012, in Ferrara, Italy.
