Reservoir Snapshot
South West Water’s primary reservoirs feeding the service area:
- Roadford Lake
- Wimbleball Lake
- Stithians
South West Water's service area in Devon and Cornwall benefits from coastal Atlantic-driven rainfall. Roadford Lake is the largest reservoir in the South West. Summer tourist demand can stretch peak-day capacity but does not normally trigger TUBs.

Frequently Asked Questions
Is there a hosepipe ban in Devon or Cornwall right now?
No. South West Water is operating normally with no Temporary Use Ban declared for summer 2026. Reservoir storage is within seasonal norms.
Could South West Water declare a TUB this summer?
Unlikely. The South West Peninsula has favourable rainfall and Roadford Lake (the largest reservoir in the region) is well-stocked. Tourist-driven peak demand in July and August can stretch capacity but does not normally trigger TUBs.
Which reservoirs supply South West Water?
South West Water draws from Roadford Lake (largest), Wimbleball Lake, and Stithians among others. Roadford serves Devon; Stithians serves Cornwall.
Does the tourist peak loading change the picture?
Yes, slightly. Cornwall's summer tourist population can double county demand. South West Water plans for this with seasonal capacity but it tightens the margin in extended dry spells. Voluntary restraint by both residents and visitors helps.
Should I still conserve water voluntarily?
Yes. Even in a water-secure region, voluntary restraint during heatwave conditions is sensible.
