South West Water appeared before Penzance magistrates on 27 September to plead guilty to breaching its consent to discharge sewage effluent into a tributary of the Newlyn Coombe, contrary to section 85(6) of the 1991 Act. Magistrates heard that Agency staff found the company's sewage works at Trevadoe covered in sewage fungus and blocked with sewage debris. Crude sewage was also overflowing from a manhole.
The receiving water contained luxuriant growths of fungus and dissolved oxygen levels were depleted, the Agency said. It blamed the incident on lack of maintenance. South West Water was fined £3,000 and ordered to pay costs of £255.
