Ardingly Reservoir Secures Drought Permit to Combat Water Shortage Crisis

Ardingly Reservoir, located near Haywards Heath in West Sussex, plays a crucial role in supplying water to approximately 280,000 customers. Currently, the reservoir is experiencing alarmingly low water levels for this time of year, with its total storage capacity recorded at just 23% as of 28 September. This marks the lowest level ever observed at this time in the reservoir’s history.

Impact on River Ouse and Local Ecosystem

The issuance of a drought permit will have significant repercussions for the River Ouse, specifically resulting in reduced water flow at Barcombe Mills. Furthermore, this permit limits the amount of water that can be released from Ardingly Reservoir to support the Shell Brook tributary of the River Ouse. Such restrictions have raised concerns regarding the overall health of the local ecosystem.

Despite the permit being granted, the Environment Agency has cautioned that it may not sufficiently bolster the security of the water supply. The agency has urged South East Water to consider additional measures within its drought management strategy. This could involve lifting certain exemptions from the existing temporary use ban or seeking to implement a non-essential use ban to further conserve water resources.

Richard O’Callaghan, the Environment Planning Manager at the Environment Agency, emphasised the careful consideration involved in granting any drought permit, stating, “We take great care weighing up the needs of the environment and will continue keeping a close eye on river conditions.” He assured that the agency remains vigilant regarding environmental impacts and will ensure that South East Water adheres to the stringent conditions outlined in its temporary permit.

Winter Conditions and Water Recovery

The upcoming winter season will be pivotal for the replenishment of water resources in the region. To facilitate the recovery of Ardingly Reservoir and alleviate the drought conditions in Sussex, at least average winter rainfall is necessary. Should rainfall fall below average, the pressure on water resources is likely to persist.

The Met Office’s forecast for October predicts average rainfall and temperatures, raising hopes for a more favourable winter ahead.

Community Involvement in Water Conservation

In light of the ongoing water scarcity, everyone has a role to play in promoting water conservation. South East Water is actively supporting the “Let’s Save Water” campaign, which aims to raise awareness about efficient water use across England and Wales. The campaign encourages simple yet effective practices, such as reducing shower time, repairing leaks at home, using a bucket or watering can instead of a hosepipe, and utilising eco modes on household appliances.

Background of the Drought Permit

The drought permit application was submitted by South East Water on 28 August. An independent Planning Inspector conducted a public hearing on 18 September, during which South East Water presented its case. This session allowed stakeholders and objectors to voice their opinions and concerns regarding the application.

The drought permit will be in effect for six months, set to expire on 29 March 2027, unless South East Water decides to withdraw it prior to that date. Typically, South East Water is expected to release four million litres (or megalitres) of water daily from Ardingly Reservoir to compensate the Shell Brook tributary, but under the new permit, this flow will be drastically reduced to just one megalitre per day.
