Yorkshire Water fined £12,000 for River Calder sewage

Yorkshire Water has been fined £12,000 after a mechanical failure at its pumping station discharged sewage into the River Calder. The water utility company was also ordered to pay full costs of £913.42 to the Environment Agency, which brought the case.

The pumping station was designed to have three pumps - a duty, assist and standby pump. In June 2011, only two pumps were present and neither worked. The standby pump had been sent away for repair, the duty pump failed because of an electrical fault, and the assist pump failed mechanically.

In mitigation, Yorkshire Water said it had no intention to cause the discharge, and there was no or little environmental damage caused.
