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.

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.

Sudan’s wartime gold boom is driving rapid expansion of artisanal mining in River Nile and Northern states, with 2–5 million people now dependent on largely unregulated operations using mercury mixers and cyanide basins near palm groves, farms and shallow groundwater. Field investigations around El-Obeidiya and Abu Hamad report millions of tonnes of karta tailings, mercury readings in Village 3 soils up to 2,825.24 (units unspecified) and earlier surveys finding mercury and cyanide in 20% of sampled drinking water north of Atbara. Artisanal mining now provides about 80% of Sudan’s gold output and 58% of export revenues, severely constraining enforcement of bans on mercury and cyanide use outside certified facilities.
