David is a chartered engineer with a BSc in Civil Engineering from Imperial College, London and a Diploma in Water Engineering. At the beginning of his career, he worked mainly on water resource studies before moving into distribution operations as Regional Technical Manager for North West Water, one of the largest UK water companies. In 1994, he became Program Manager for leakage. His efforts were critical in maintaining supplies to a population of over 3 million customers (8 million people) through the major drought of 1995/96 and driving a leakage strategy that saw losses halved in 4 years—a reduction of over 450Ml/d. He was a member of the UK national leakage group and has been the client manager on a number of national research projects. After a total of 33 years of experience in the industry, David now works as an independent consultant and has worked for a number of clients both in the UK and internationally. He became a key member of the IWA Water Loss Steering Group and was awarded membership of the IWA fellow’s program for his achievements and contributions to the group.
