A consultation has opened as South West Water seeks permission to process more sewage waste in St Mabyn,Cornwall.

South West Water has applied for an environmental permit. This will allow the water company to upgrade the capacity of its Wadebridge Road wastewater treatment works. Extra volume of 12m3 per day – the same capacity as a large van - is requested so that the site can process sewage from the Chapelfields housing development. This waste is currently being taken away by tanker for treatment elsewhere.

The Environment Agency is ‘minded to’ accept this permit request as the initial application was consulted on between 20 August and 17 September 2025. A second consultation period is now open and, to reflect high public interest, will be run for an extended period and close at 11.59p
