Environment Agency publishes 2024 storm overflow spill data for England

The Environment Agency has published annual water company Event Duration Monitoring (EDM) return data for 2024. This data show the frequency and duration of spills from sewage treatment plants as a result of storm overflows in England. 

The data for 2024 show a 2.9% decrease in the number of sewage spills compared to 2023. However, spill durations increased by 0.2%. The 2024 data show that storm overflow spill counts and durations remain unacceptably high.

The data also shows that in 2024:  

• The average number of spills per overflow was 31.8, compared to 33.1 in 2023 and 32.6 in 2020;
• 39% of storm overflows spilled less than 10 times in 2024, compared to 40.5% in 2023 and 40% in 2020; and
• 12.5% of storm overflows did not spill at all in 2024, compared to 13.9% in 2023 and 13% in 2020.

In January 2025, the Environment Agency secured a major commitment of actions and investment from water companies to clean up waterways. The Water Industry National Environment Programme (WINEP) sets out over 24,000 actions water companies must take over the next five years to meet their legal requirements for the environment. It is understood this represents a £22.1bn investment, including around £10.2bn to improve storm overflows in England, including nature-based solutions which reduce the amount of rainfall reaching overflows.

Water companies have committed to upgrading over 2,500 storm overflows, which the Environment Agency expects to reduce annual sewage spills by 85,000. Water companies are also due to install 3,500 monitors at emergency overflows sites, protecting and enhancing 13,500 km of river.

Lincolnshire waste offender required to pay a large additional penalty due to undeclared assets

A convicted waste offender must now significantly increased proceeds of crime after the Environment Agency re-opened an inquiry into his finances and discovered he had undeclared assets.

The man’s case was re-opened after the Environment Agency learned of changes in his financial position. It was discovered that he owned a property that he had not declared at the time of his sentencing, when only £8,317 was recovered from him because it was believed he had limited means.

The man was originally prosecuted in the summer of 2021 for waste crime offences. He was given a suspended prison sentence for storing and burning waste illegally at a site in Holbeach, Lincolnshire, despite repeated warnings from the Environment Agency.

At court on 27 February 2025, it was re-calculated that the man benefited from his illegal waste activities by £286,809.94.

During the initial investigation, Environment Agency officers visited the Holbeach site on six occasions and told the man verbally and in writing to stop bringing waste to the site and burning it. However, on returning to the site, Environment Agency officers found more waste had been brought to the site and burned.

Waste observed at the site during the multiple visits included household waste, furniture, mattresses, clothing, paint cans, toilets, televisions and numerous fridges. Some of the rubbish had been burned, prompting neighbours to complain about the smoke generated. Fridges are classed as hazardous waste and require specialist disposal.

Additional penalty

The man was ordered to pay an additional £278,492.92. He was given three months to pay the remainder or to serve five years imprisonment, and was ordered to make a £1,500 contribution towards the Environment Agency’s costs.

This is on top of the £8,317.02 he paid after being sentenced in 2021.

Waste company prosecuted for failing to comply with a demand for information about accepted materials

A business and a designated member of the partnership have been fined after failing to comply with a formal information notice served on by the Environment Agency.

Tetron Welbeck Limited Liability Partnership has had an environmental permit since 2013 to operate a site at Welbeck Colliery near Mansfield, Nottinghamshire. It was stated that the business changed hands around 2020.

The Partnership failed to comply with a formal information notice served on it after it failed to provide information requested by the Environment Agency. The information was required to allow the Environment Agency to audit the site in order to ensure waste within the correct category was being accepted. The deadline in the notice for the receipt of the information was 15 June 2023. No information was received.

A work plan was provided on 15 June 2023, but this did not include the required information. Despite engaging with the Environment Agency, the man, who was a designated member of the partnership, did not provide the information required.

Further attempts by the Environment Agency to obtain the relevant information failed.

Breach
