Introduction
The fourth Water Pipelines Conference focussed on the issues which 'Change the Game'.

The water industry worldwide is changing rapidly and leading companies in many countries are embracing emerging technologies to remain ahead of the competition. The Technical Committee has sought to bring together contributions from what are called learning organisations - those whose innovative skills, systems and investments are leading the way.
