Water and world development

Welcome to this bumper edition of Water & Sewerage Journal, complete with its annual buyers guide directory.

The expert articles in this issue range from pipelines to customer billing and from leakage control to carbon management.

We also feature sections on flooding, microbiology, sludge processing and managing sewer maintenance. We hope you find the articles both stimulating and informative, and welcome your feedback. Looking at the agenda of World Water Week being held in Stockholm as I write, on the theme ‘Water and Development’, we might think that the problems being discussed do not concern this country. However, with a growing urban population, water supplies to some areas are competing with demands from industry and agriculture, if not to the same extent as in warmer developing countries.

In her foreword to this edition on behalf of the Business in the Community Water Taskforce, Gudrun Cartwright tells us how, with water high on the World Economic Forum’s list of priorities, UK businesses are already looking for solutions to ensure a sustainable future. And with energy use also high on the business agenda, Keith Colquhoun of Thames Water explains some of the measures the water company is exploring to reduce consumption and maximise the potential of renewable energy (page 77).

The water industry has been very much in the public eye in the last 12 months, with widespread flooding in the south of England following three years of record- breaking rainfall and, more recently, a major cryptosporidium control exercise in the North West. From a global perspective, these issues only serve to highlight our privileged position: We have water and we have an organised supply system which is able to react to such emergencies and provide solutions.

Southern Water found one solution to the groundwater flooding in their region by using mobile treatment tanks (see page 21) and United Utilities’ rapid response (in real terms if not some customers’) has meant installing ultraviolet water disinfection centres across the affected region. However, confirming and containing the source of the outbreak is not always straightforward, as Helen Clay-Chapman tells us in her account of a recent CIWEM workshop into cryptosporidium management (page 65).
