Reservoir Snapshot
Southern Water’s primary reservoirs feeding the service area:
- Bewl Water (shared)
- Darwell
- Powdermill
Spring 2025 was the driest in 132 years and summer 2025 the hottest on record since 1884. Winter 2025-26 recharge in southern England was below normal. Bewl Water and Southern Water reservoirs entered summer 2026 below their summer-readiness target. Ardingly reservoir (operated by South East Water but in the same regional climate) has been highlighted as unlikely to fully recover even with full winter rainfall.
For current reservoir percentages, see the Environment Agency monthly water situation reports at gov.ukand the company’s own drought management plan.

UK Lawn Care During Southern Water Restrictions
UK lawns are cool-season grasses (Perennial Ryegrass, Fescue blends, Bent). Under a TUB you can keep your lawn alive with selective watering-can use in the early morning. Raise mower to 50 to 60 millimetres. Stop fertilising entirely. Allow some browning. The lawn will recover when autumn rain returns.
