The court heard that the company received a call from a member of the public about sewage overflowing in Rainworth on 1 April 2003. Although it was clear that the discharge was polluting a watercourse, the company failed to attend until 3 April when the problem had become much more severe.
Samples taken by the Environment Agency showed that the dissolved oxygen content of the water had been almost halved.
Fining the company, the magistrates highlighted the company's delay in responding to the incident as an aggravating factor. The company promised to respond immediately in future.
It was the company's third pollution offence this year. In February, it was fined £15,000 after breaching a discharge consent at a water treatment works (ENDS Report 362, p 61 ). In January it was fined £6,500 after a leaking sewer killed 500 fish (ENDS Report 361, p 61 ).
