A new environmental permit for Wadebridge Wastewater Treatment Works

We have issued the environmental permit for St Mabyn wastewater treatment works.

South West Water (SWW) applied for an environmental permit to expand its wastewater treatment works on Wadebridge Road, St Mabyn. Between 10 December 2025 and 27 January 2026, we asked for your views on our draft permit and draft decision document. Thank you to everyone who took the time to respond.

We received 23 responses during the consultation. We carefully considered all comments and questions before making our final decision. We have now issued the environmental permit to South West Water.

Our final decision document explains the issues raised during the consultation and how we took them into account when reaching our decision.

Once available, you can view the final decision document and environmental permit on Public Registers Online by searching for the permit number, EPR/NP3924LT.

Environmental permits help protect people and the environment by setting clear conditions that operators must meet. When we assess permit applications, we review the available evidence, consider consultation responses and make sure the proposal meets legal and technical requirements.

If a permit application meets these requirements and there are no grounds to refuse it, we must issue the permit. This follows the Regulators' Code, which requires regulators to carry out their work in a way that supports both environmental protection and sustainable economic growth.
