Yorkshire Water has been fined £733,333 for three sewage pollution incidents that occurred between 2018 and 2019 in Pools Brook country park near Chesterfield. The company admitted to the pollution events, which resulted in the death of fish and insects and affected water quality over a distance of more than 600 metres in some cases.

Impact on the Environment and Wildlife

The first incident, which occurred on 1 October 2018, was caused by a burst pipe at the Pools Brook sewage pumping station. The pipe, which was severely corroded, allowed untreated sewage to spill into the stream. This led to the death of fish such as tench, pike, and roach, as well as river insects in the park’s pond. The contamination stretched over 600 metres, affecting the ecosystem and water quality.

The second incident took place on 27 February 2019 and was caused by a blockage in the plastic foul sewer pipe, mainly from wet wipes. This caused a pressure build-up in one of the pipe’s joints, leading to a leak of sewage into the surface water pipe and into the stream. Although no fish were killed in this incident, the water quality was affected for 700 metres.

A third incident occurred on 7 August 2019, when a joint coupling in the same plastic foul sewer pipe failed, causing sewage to spill into the surface water pipe and into the Pools Brook stream. Similar to the second incident, there was no evidence of fish death, but water quality was affected for over 600 metres.

Environmental Agency’s Response

The Environment Agency, which investigated the incidents, stated that Yorkshire Water would not attend an interview for any of the three events. Alan Lovell, the agency’s chair, said that polluting the same stream three times in less than a year is unacceptable. He added that the company has now been dealt with by the courts following the investigation and that the agency expects full compliance and is committed to taking strong enforcement action in cases of serious breaches.

Yorkshire Water’s spokesperson acknowledged the incidents and stated that the company has invested over £2.5 million in the seven years since the last incident to relocate the two sewers involved. The company also emphasized that it has identified key learnings from the incidents and implemented changes across its business to prevent similar occurrences.

The spokesperson said that the company has also reviewed its internal processes to enhance them where necessary. Protecting the environment is a key priority, and when incidents fall below normal standards, the company ensures they are thoroughly investigated and corrective actions are taken to prevent recurrence.

The spokesperson added that no pollution incident is ever acceptable. The company expressed regret for the impact of the 2018 and 2019 incidents at Pools Brook, which were attributed to an inadequate external protective coating on one of the sewers and wet wipes causing blockages in the other.

Future Environmental Commitments

Yorkshire Water also noted that it is working on its largest environmental investment programme to date, which is expected to reach £8.3 billion before 2030. This investment aims to improve infrastructure and reduce the risk of future pollution incidents.

The Environment Agency has not provided a timeline for further enforcement actions or potential additional penalties. However, the agency has emphasized the need for continued compliance with environmental regulations and has called for transparency in the company’s operations moving forward.

Local residents and environmental groups have called for stricter oversight and more frequent monitoring of water companies to prevent similar incidents. They argue that such pollution not only harms wildlife but also poses risks to public health and recreational activities in the area.

The incidents at Pools Brook serve as a reminder of the ongoing challenges faced by water companies in maintaining infrastructure and preventing pollution. The Environment Agency and other regulatory bodies are expected to continue monitoring the situation closely and may take further action if necessary.
