Centre for Water Systems

The Centre for Water Systems was established in August 1998 by Prof Godfrey Walters and Prof Dragan Savic, who have together, developed a productive research group of 20 people working on projects ranging from sewer design to reservoir operation.

The Centre aims to fulfil a real need for both fundamental and applied research into water systems engineering.  As the expansion and development of the world population continues, it brings with it increased industrialisation, intensive agriculture, increased pollution and possible climate changes, thereby putting severe pressure on water resources.  The provision of an adequate and reliable supply of safe, clean water and the safe treatment and disposal of waste-water are set to become high political priorities world-wide.

CWS has numerous links academia and industry, both nationally and internationally.  On the academic side, CWS currently holds joint research projects with the University of Sheffield and Imperial College, whilst active collaboration proceeds with universities in Adelaide, Manitoba, Sao Paulo and Rabat.  On the industrial side, the Centre is working with most of the UK water Companies, the Environment Agency, the Post Office, leading international consultants Halcrow and Binnie Black and Veatch and specialist UK water consultants, Ewan Associates Ltd.

The Centre currently holds five EPSRC research grants totalling £1,021,059 and industry sponsored research contracts worth £138,000.
