England’s water companies reported more than 50,000 sewage discharges outside the required timeframe during the first half of 2026, according to new analysis by Surfers Against Sewage.
The charity’s 2026 Water Quality Report says all nine water and sewerage companies in England missed the reporting deadline during the period.
Industry coverage published on 8 October says more than 4,000 delayed reports affected designated bathing waters monitored by the Environment Agency.
The findings are campaigners’ analysis, rather than the outcome of a completed regulatory investigation. Yorkshire Water has challenged the methodology.
What companies must publish
Government guidance confirms that, since 1 January 2025, water and sewerage companies have been required to publish near-real-time information about storm overflow discharges.
They must publish when a discharge begins and the overflow’s location within one hour of its beginning. Information about the end of a discharge must also be published within one hour.
The information must be readily accessible and understandable to the public. Ofwat oversees compliance with this duty.
The reporting obligation is distinct from the question of whether an individual discharge itself breaches environmental rules.
Yorkshire Water disputes findings
The charity’s analysis attributes more than 13,000 delayed reports to Yorkshire Water, the highest company total.
In a response reported by Sky News through Black Country Radio, Yorkshire Water disputed the research methods and said its own figure was 4,490 discharges published later than one hour up to 7 October.
The company said regulatory compliance concerned reporting to the National Storm Overflow Hub and Ofwat, rather than when Surfers Against Sewage received notifications.
The figures cover different periods and should not be treated as directly equivalent measurements. The disagreement highlights the importance of how reporting delays are defined and tracked.
Dry-weather discharges also highlighted
Surfers Against Sewage says at least 70,400 hours of sewage discharges occurred on dry days in the first six months of 2026.
Water Magazine reports that the charity’s 2026 discharge data includes raw water-company information that has not been verified. It also notes that this dataset is not directly comparable with the annual returns used for 2025.
The charity’s delayed-reporting analysis draws on live company data tracked through its Safer Seas and Rivers Service.
Campaigners call for stronger enforcement
Surfers Against Sewage is calling for greater transparency, stronger enforcement and changes to how the industry is owned and governed.
The report raises questions about the effectiveness of public warnings and regulatory oversight. It does not, by itself, establish that every alleged late report represents a proven legal breach.
