A reservoir supplying water to nearly 280,000 residents in Haywards Heath, West Sussex, and nearby areas in East Sussex is at risk of running dry within weeks, raising concerns about the possible return of standpipes on British streets for the first time in half a century. Ardingly Reservoir’s water levels fell from 22.8 percent full to 20.2 percent in just one week, exacerbated by rainfall that has been significantly below average in recent weeks.
The situation has become increasingly severe amid a broader national drought emergency, with drought conditions officially declared last week in Yorkshire, joining ten other English regions facing similar challenges. Water management officials have convened regularly to assess the growing threat to supply.
John Halsall, chief executive of South East Water, the utility responsible for the area, highlighted the gravity of the situation. He warned that if rainfall continues to remain about 60 percent below normal, Ardingly Reservoir could reach "day zero," or complete depletion, by mid-November. Should the drought persist, South East Water plans to seek government approval from Environment Secretary Dame Angela Eagle to escalate drought response measures, which could include reinstating standpipes and imposing scheduled water supply interruptions known as “rota cuts.” These measures were last used in the 1970s.
Halsall emphasized the reservoir’s “flashy” nature, meaning its levels can fluctuate rapidly, and said that timely rainfall could delay the worst-case scenario. However, his firm has already cancelled certain exemptions to Sussex’s ongoing hosepipe ban, which is expected to remain in place into next year. South East Water is among three companies seeking government authorization to enforce bans on non-essential water use, potentially restricting activities like filling swimming pools and washing vehicles—restrictions not seen in the UK for 20 years.
Despite campaigns to encourage water conservation, customer demand has only decreased by about 5 percent, below the target reduction of around 10 percent. Halsall acknowledged that recent water outages, notably in Tunbridge Wells where the firm’s former chief executive resigned amid public backlash, have eroded consumer trust. The company is now stepping up efforts to regain confidence, including dispatching plumbers to assist customers in reducing water consumption.
Compounding the challenge are an increased number of burst pipes, attributed to ground movement caused by an unusually dry spring and summer. These leaks have become visible reminders to customers of the crisis, complicating the company’s message about conserving water.
Looking ahead, Halsall could not guarantee that similar water outages would be avoided this winter but assured that South East Water is doing all it can to improve system resilience. The company has dismissed a proposed pipeline from another reservoir due to environmental concerns, including the impact on protected wildlife habitats. Instead, it is considering upgrades to local water treatment facilities and plans to release more water upstream into the River Ouse, which feeds Ardingly Reservoir.
Water storage levels across England remain low, averaging 54 percent full—around a fifth below the typical volume for this time of year. Environment Agency research indicates that rainfall would need to exceed average levels by about 20 percent through April to end drought conditions nationwide. Forecasts predict some light rain in the Haywards Heath area this week, but the overall outlook remains uncertain.
