Chief executive of Northumbrian Water John Cuthbert and chief executive of Yorkshire Water Kevin Whiteman will deliver key note presentations.
Delegates will also hear from expert speakers on the theme 'Climate Change – Our Role in a Global Crisis'.
Incoming IWO president and managing director of South Staffordshire Water Jack Carnell will chair this year's conference:
"The water industry is responsible for around 2% of UK carbon dioxide emissions – largely the result of our energy consumption.
"As practitioners we have a huge responsibility and a real opportunity; from water efficiency and renewables through to capital investment, innovation and procurement practice. This Conference will present and debate what we have done, what we are doing and what we have yet to do," he said.
The IWO Conference will take place from Thursday 23 April – Saturday 25 April 2009 at the Sage Gateshead.
