South West Water Dumps Untreated Sewage, Breaches Scilly Standards

7/29/2026

Summary

SWW Dumping

SWW is dumping untreated sewage into the sea around the Isles of Scilly.
The islands must meet water standards by 2027 after their exemption ended.
The Environment Agency warned that SWW’s longer-pipe plan, which only screens solids, violates regulations.
After protests, SWW said it will treat wastewater locally but lacks a sludge disposal method.
Local groups warn the discharge harms tourism and wildlife, including seals, dolphins and about 100 puffins.

Summary

SWW Plans Upgrades

South West Water (SWW) took control of the Isles of Scilly wastewater network in 2020 and found it fell short of regulatory requirements.
SWW is planning a multi-year investment programme to upgrade the infrastructure, boost resilience and protect water quality for island residents.
The utility says the upgrades will require significant capital spending, costs undisclosed, while it listens to island customers and acknowledges the technical challenges lack straightforward solutions.
