Question to the Ministry of Defence:

To ask the Secretary of State for Defence, how many sewage leaks have been recorded within their Department's estate in the last twelve months.

Water and wastewater services across the majority of the Defence Estate sites in Great Britain are provided by five service providers. Those service providers have confirmed to the Ministry of Defence (MOD) that a total of 102 sewage leaks have been recorded from sewage treatment facilities on the Defence Estate within the last 12 months.

The sewage leaks occurred at four sites: Culdrose, RAF Henlow, Lyneham, and Faslane, all of which have a Storm Overflow Consent issued by the regulator (The Environment Agency for England and Wales, and the Scottish Environment Protection Agency (SEPA) for Scotland). The MOD complies with appropriate legislation and Environment Agency requirements.
