Severn Trent has announced plans to cut 600 jobs at its main water business.
Based in Birmingham, Severn Trent supplies water and treats sewage for about eight million people in the Midlands and parts of Wales.
The company warned last year that it needed to cut jobs in order to lower costs, stating that they had suffered with increasing energy prices and had spent profit fixing pipe leaks.
The jobs to go will include both full time positions and agency jobs and will happen across the next five years. Further details of the cuts are due to be released in June.
