UK Reservoir Nears Empty: Drought Fears Grip Sussex

Ardingly reservoir, a key water source for approximately 95,000 properties in Sussex, is critically low at just 19% of its capacity following the UK's hottest summer on record. Residents express alarm at the visibly receding water levels, a stark contrast to the expected volume at this time of year. The situation is further complicated by the Weir Wood reservoir, located less than six miles away, which has been out of service since 2018 due to a non-operational water treatment works.

Despite recent rainfall, drought conditions persist across large parts of England and Wales, with a severe drought declared in several southern counties. This severe drought status signifies potential harm to public water supplies and critical services. Concerns are mounting over increasing water demand from population growth and new industrial needs, alongside reduced water availability due to climate change and historical underinvestment in infrastructure and reservoir capacity.

Southern Water is currently undertaking a significant rebuild of the Weir Wood treatment works, expected to be completed by 2030, to ensure long-term water resilience. South East Water is also exploring options for connecting the two reservoirs. However, residents are frustrated by the inability to utilize the nearby full reservoir, especially when urged to conserve water and even stockpile essentials, highlighting a pressing need for improved water infrastructure and management in the face of escalating climate challenges.
