Matthew Wright, the former chief executive of Southern Water, appeared in court Friday facing a charge of fraud conspiracy related to alleged plans to manipulate water quality tests. Wright, 60, appeared at Bromley Magistrates' Court alongside three other former employees: Philip Barker, 57; Clive Massey, 64; and Mark Gregory, 63.
The group is accused of conspiring to defraud the Environment Agency and water regulator Ofwat between January 2012 and December 2017. Prosecutors allege that the individuals manipulated the company's self-monitoring regime by creating artificial "no-flow events" at wastewater treatment works. These events allegedly occurred when sampling was planned, ensuring that insufficient water flow would prevent tests from being conducted, thereby avoiding potential failures and fines estimated to be £45 million or higher.
According to a previous High Court ruling, Barker, Massey, and Gregory held officer or senior operations manager positions at Southern Water during the period of the alleged offenses. The charge summary states the individuals are accused of "defrauding persons performing public duties in respect of environmental and financial regulation of Southern Water Services Limited."
Southern Water itself faces numerous separate charges for allegedly failing to comply with or contravening environmental permit conditions. Also appearing in court were Mark Butler, 45; David James, 58; and Terry Stephens, 67, who are accused of the same offense.
District Judge Stephen Leake deemed the charges related and transferred the case to Maidstone Crown Court, with a future appearance scheduled for October 9. Wright, Gregory, and Butler were present in court for Friday's hearing, while the others appeared via video link. All defendants were granted unconditional bail.
Wastewater treatment facilities operate under environmental permits issued by the Environment Agency. Since 2009, these facilities have been subject to an "operator self-monitoring" scheme, where water companies conduct tests on treated effluent. These tests are meant to ensure compliance with permit regulations, with penalties for non-compliance. A "no-flow event," where discharge flow is insufficient for sampling, is not recorded as a failure under this scheme. Wright, who joined Southern Water in 2011 and left in December 2016, denies any wrongdoing and has reportedly cooperated with the Environment Agency's investigation.
