The Environment Agency has ordered Wessex Water to carry out more than 280 improvements after a wide‑ranging series of inspections across the company’s wastewater network.
Officers completed over 790 inspections of Wessex Water sites during 2025–26 as part of a national programme that has seen the Agency reach a record 10,000 checks of water industry assets in the past year.
The inspections uncovered a number of issues across the region, including faulty monitoring equipment, inadequate stormwater storage, leaking pipes, groundwater infiltration, and inconsistent maintenance that had led to blocked channels and overgrown vegetation.
Despite the concerns, 72% of sites were found to be compliant with their environmental permits.
Ed Lockington, water industry regulation manager for the Environment Agency, said the stepped‑up inspection regime was already driving improvements.
“Each inspection pushes Wessex Water to improve the key parts of its network we all depend upon, including the environment,” he said. “A strong loop of inspecting, fixing, inspecting and maintaining is at work and will help Wessex Water eliminate issues before they can harm the environment.”
Helen Wakeham, the Agency’s Director for Water, said the regulator was changing how it operates, with more staff, better data and stronger enforcement powers.
“Inspections are a vital preventative measure,” she said. “Nationally, our teams have issued over 3,000 actions to water companies, including repairing sewage works and upgrading infrastructure. Together, this will drive meaningful improvements in performance and create a cleaner water environment.”
While many of the breaches identified at Wessex Water sites were classed as minor, the Agency says they still reflect how well a company manages its assets to protect the environment. More serious breaches may be referred for further investigation, which could lead to prosecution or other enforcement action.
The Agency says the intelligence gathered from the increased inspections is helping it build a clearer picture of operational trends and areas of non‑compliance across the water industry.
Wessex Water is set to invest £3.5 billion over the next five years as part of a wider £22.1 billion national programme agreed with regulators to upgrade infrastructure and meet tighter environmental standards.
Compliance Assessment Reports for each inspection are available online as part of the Environment Agency’s transparency measures.
