Following the UK’s hottest summer on record, the Ardingly reservoir in West Sussex has dropped to just 19% capacity, sparking deep concern among local residents. The depleted water levels come as severe drought declarations remain in place across parts of England and Wales.
Residents Raise Concerns Over Water Levels and Infrastructure
Lifetime Haywards Heath resident Caroline Allan told The Guardian that she has never witnessed the water level at Ardingly fall this low. Despite a grey and rainy day during the outlet’s visit, the weather failed to mask the muddy reservoir bed, which should normally be submerged under six meters of water.
Managed by South East Water, the reservoir supplies approximately 95,000 properties around Haywards Heath and Uckfield. Local frustrations have mounted over ongoing housing developments that residents argue are straining regional resources while water storage capacity remains static.
As the climate crisis causes hotter, drier summers and unpredictable rainfall, water demand continues to rise due to population growth and industrial needs. Meanwhile, decades of underinvestment have left infrastructure vulnerable to leaks and shortages.
Neighboring Reservoir Untapped Due to Broken Works
Less than six miles away from Ardingly, Southern Water’s Weir Wood reservoir sits at 80% capacity. However, the site’s water treatment works have been out of action since 2018, rendering the water unusable for the local population.
Allan described the situation as madness, questioning why the full neighboring reservoir cannot be utilized. Graham Ward, another lifelong resident, echoed these sentiments, calling the inability to use the Weir Wood facility “crazy.”
During a 2018 drought, South East Water proposed connecting Ardingly and Weir Wood via an overground pipeline, but the plans were shelved once rainfall returned. Southern Water is now working to rebuild the Weir Wood treatment plant by 2030, while South East Water is conducting a feasibility study for a buried connecting pipeline.
Southern Water explained that the Weir Wood facility, built in the 1950s, reached the end of its operational life and faced significant reliability and water-quality challenges before being taken out of supply. A spokesperson added that even if the facility were operational, it would not resolve the current situation at Ardingly.
With government guidance advising citizens to stockpile essential goods, local residents like Ward have already begun storing water at home. Ward criticized the crumbling infrastructure, warning that dry summers will make shortages a recurring annual crisis.
Delphine Hazeldon, a Haywards Heath resident of over 20 years, shared similar anxieties, noting that relatives in Australia follow the situation with horror.
Water minister Emma Hardy, who chaired a national drought group meeting, stated that the situation remains serious despite recent rainfall. She emphasized that water companies must take every measure to secure current supplies and prepare for the spring.
South East Water declined to comment on the matter, as reported by The Guardian.
