How could the severe drought declaration affect South West Water's operations?

Likely What happens if… A possibility worth considering, not a forecast.

South West Water faces operational strain as drought lowers reservoir capacity. The Environment Agency declared severe drought in parts of Cornwall, Devon, Dorset, Somerset, East Sussex, and West Sussex following an exceptionally hot and dry summer. This has significantly impacted water supplies across the region. For South West Water, this means reservoirs are operating under extreme stress, as evidenced by Wimbleball on Exmoor dropping to 14.9% capacity. This situation necessitates managing reduced water availability and maintaining supply for the 400,000 people it serves.

Why it matters

South West Water faces the immediate challenge of maintaining water supply for 400,000 people while managing severely depleted resources. The drought highlights the strain on existing infrastructure and the need for behavioral change and investment in new reservoirs, which the Chartered Institution of Water and Environmental Management has called for.

This situation is part of a broader climate emergency, as water reuse and efficiency are deemed necessary because the UK is using double the amount of water it used 50 years ago.

What we don't know yet

  • Will the Environment Agency mandate specific water restrictions for South West Water?
  • How will the reduced reservoir capacity affect the long-term supply security for the 400,000 people served?
