England and Wales’ four main water regulators have issued a first joint performance report, finding treated drinking water quality remains high while pollution incidents from wastewater networks and storm overflows are still unacceptably frequent. The consolidated assessment compares all water and sewerage companies on metrics such as serious pollution events, leakage per kilometre of main, and compliance with discharge permits. For civil and environmental engineers, the report signals continued regulatory pressure on CSO capacity upgrades, sewer rehabilitation, and treatment works resilience rather than on potable water process redesign.

Enersea in the UK and Dutch firm Carbon Haven are jointly developing an offshore CO₂ injection system to convert depleted North Sea gas platforms into permanent storage sites. The concept focuses on reusing existing jackets, topsides and subsea pipelines to transport and inject captured CO₂ into exhausted gas reservoirs, avoiding new large-diameter trunklines and minimising new offshore construction. For civil and geotechnical engineers, the work centres on verifying long-term well integrity, platform structural capacity under altered loading, and caprock sealing performance for geological containment.

Anglian Water has been fined £1.6M after local mismanagement led to untreated sewage discharges into the River Brain in Essex over a six-week period in 2022, breaching its environmental permit. The Environment Agency investigation found operational failures at wastewater assets rather than storm-related exceedance, pointing to inadequate on-site oversight and response procedures. For civil and water engineers, the case signals closer regulatory scrutiny of network operations, incident logging and real-time monitoring on combined sewer overflows and treatment works.
