Ardingly Reservoir in West Sussex is currently only 19% full, a stark symbol of England's worsening drought crisis. The reservoir, managed by South East Water, serves about 95,000 properties in and around Haywards Heath and Uckfield, and its depleted state has residents worried about the future of their water supply.
Caroline Allan, a lifetime resident of Haywards Heath, told the Guardian: “You can see the water level at Ardingly going down and down. I don’t remember ever seeing it this low.” Her concern is echoed by many in the community as the reservoir bed, which should be submerged under six metres of water, lies exposed and muddy.
Severe Drought Declared Across Southern England
Earlier this month, a severe drought was declared in parts of Devon, Cornwall, Dorset, Somerset, East Sussex and West Sussex. This is the highest level of drought and is declared when evidence shows drought is causing or will soon cause serious harm, and when emergency action is needed to protect people, water supplies, the environment, farming, infrastructure or other critical services.
The declaration follows the UK's hottest summer on record, which has left reservoirs across the country at exceptionally low levels. The Environment Agency and water companies are taking urgent measures to secure public water supplies.
Why Ardingly Reservoir Matters
Ardingly Reservoir is a critical source of water for tens of thousands of homes and businesses. Its current level of 19% is far below normal and raises questions about the resilience of local water infrastructure.

The reservoir is also a popular spot for walking and nature, and its dramatic shrinkage has become a visible reminder of the drought's impact. The muddy banks and exposed reservoir bed stand in stark contrast to the grey, rainy weather on the day the Guardian visited, highlighting that short-term rain is not enough to replenish long-term deficits.
Residents Fear Permanent Hosepipe Ban
Caroline Allan expressed frustration not only at the low water levels but also at the prospect of indefinite restrictions. “They will probably never lift the hosepipe ban and it just seems so unfair that they’re making the area more and more crowded but they’re not increasing the capacity to store water,” she said.
Her comments reflect a growing tension between housing development and water resource management. Haywards Heath has seen a steady stream of new housing developments, sparking local opposition and concerns that the infrastructure is not keeping pace with population growth.

The Broader Drought Picture
The situation at Ardingly is not isolated. Across England, reservoirs are exceptionally low, and the drought is affecting everything from agriculture to household water use. The severe drought declaration in multiple counties signals that emergency action is required.
As climate change brings more frequent and intense heatwaves, the pressure on water resources is expected to increase. The government and water companies are facing calls to invest in new reservoirs and better water management systems.
- Ardingly Reservoir is only 19% full, serving 95,000 properties.
- Severe drought has been declared in parts of Devon, Cornwall, Dorset, Somerset, East Sussex and West Sussex.
- Residents fear hosepipe bans will become permanent.
- New housing developments are adding pressure on already strained water supplies.
- The UK experienced its hottest summer on record, exacerbating the drought.
What This Means for Residents and the Environment
For residents, the immediate concern is the security of their water supply and the longevity of restrictions. For the environment, low reservoir levels can harm wildlife and water quality. The severe drought declaration allows authorities to take emergency measures, but long-term solutions are needed.

The situation at Ardingly highlights the need for a more resilient water infrastructure. As one of England's worst-hit reservoirs, it serves as a warning of what could happen elsewhere if action is not taken.
Comparison of Reservoir Levels
While Ardingly is at 19%, other reservoirs across the UK are also suffering. The table below shows how different regions are faring based on available data.
| Reservoir/Region | Current Level | Status |
|---|---|---|
| Ardingly Reservoir, West Sussex | 19% | Severely depleted |
| Devon and Cornwall | Low | Severe drought declared |
| Dorset and Somerset | Low | Severe drought declared |
| East Sussex | Low | Severe drought declared |
What to Watch Next
Water companies are under pressure to reduce leakage and invest in new storage. The government may need to intervene to ensure water security. Residents will be watching closely to see if restrictions are lifted or if new measures are introduced.
The drought is a wake-up call for the UK's water infrastructure. As the climate changes, the country must adapt to ensure a reliable water supply for all.

FAQ
What is the current water level at Ardingly Reservoir?
Ardingly Reservoir is currently 19% full, according to South East Water. This is significantly below normal levels and has raised concerns among residents and authorities.
Why has a severe drought been declared?
Severe drought is declared when evidence shows drought is causing or will soon cause serious harm to public water supplies, the environment, farming, or infrastructure. The UK's hottest summer on record has left reservoirs exceptionally low, prompting the declaration in several counties.
How many properties does Ardingly Reservoir serve?

Will the hosepipe ban be lifted?
It is uncertain when the hosepipe ban will be lifted. Residents like Caroline Allan fear it may become permanent, especially as housing developments increase demand without corresponding investment in water storage capacity.
As England grapples with this crisis, it's worth looking at how other regions are coping. The UK drought 2024: five reservoirs exceptionally low shows the scale of the problem across the country. Similarly, England reservoirs exceptionally low amid persistent drought provides a wider context.
Some have suggested that the Environment Agency and Natural England should be scrapped, but critics argue this would weaken environmental protections. The debate over Tories to scrap Environment Agency and Natural England is ongoing. Meanwhile, other countries are facing similar challenges, such as the Ebro reservoir water crisis: why Spain's biggest basin dried.

Experts argue that new reservoirs are needed, and that the state should lead water infrastructure projects. The case for new reservoirs: why state should lead water infrastructure is gaining traction. In the Middle East, Israel threatens seizure of ancient water reservoirs near Bethleh (sic) and Israel threatens to seize ancient water reservoirs near Bethlehem show how water can be a source of conflict. Closer to home, Europe's drought crisis: why northern countries now want more reservoirs highlights a shift in attitudes.
