Environment Agency: Wimbleball Drought Permit Granted to South West Water

• The Environment Agency has issued a drought permit to South West Water for Wimbleball Reservoir due to critically low water levels.
• Wimbleball Reservoir's capacity was at a critical 18% on October 4th, significantly below the 30% recorded last year.
• The permit allows a temporary pause in compensation flow to the River Haddeo, provided equivalent water is released to the River Exe for public supply.
• South West Water has applied for a non-essential water use ban affecting businesses in Mid Devon, East Devon, and Dorset.
• The government's strengthened Water Bill is set to introduce significant reforms for the water industry.

The ongoing scrutiny of water companies and planned Water Bill reforms signal a tightening regulatory environment for the water sector, requiring proactive compliance reviews.

The Environment Agency has formally granted a drought permit to South West Water, a critical measure intended to safeguard public water supplies originating from Wimbleball Reservoir. This decision comes as Wimbleball Reservoir water levels have plummeted to an exceptionally low 18% of its total storage capacity as of October 4th. This figure represents a significant decline from the 30% recorded at the same time last year, with the visible emergence of Bessom Bridge serving as a stark indicator of the reduced water volume in the Exmoor, Somerset reservoir, which supplies approximately 390,000 individuals.

The Environment Agency Wimbleball drought permit temporarily modifies South West Water's operational requirements. It allows the utility to suspend the standard River Haddeo compensation flow, a measure typically mandated to maintain ecological balance. However, this suspension is conditional upon South West Water releasing an equivalent or greater volume of water downstream. This released water is crucial for supporting UK water abstraction license activities from the River Exe, which are vital for public supply. The primary objective of these conditions is to preserve Wimbleball’s diminishing water reserves while simultaneously protecting the environmental integrity and wildlife of both the River Haddeo and the River Exe.

South West Water's application for this permit was initially submitted on September 16th, subsequently amended thirteen days later. Facing a deteriorating water situation, the company filed an urgent request on October 1st, seeking to bypass the public examination process for objections. This request was approved, leading to the Environment Agency's swift issuance of the permit on October 2nd, which remains active. The permit will remain in effect until February 28, 2027, unless South West Water withdraws it before then. Despite this intervention, the Environment Agency has explicitly stated that the permit alone will not be sufficient to secure water supplies, emphasizing the ongoing necessity for South West Water to diligently execute its comprehensive South West Water drought plan.

In response to the persistent drought conditions, the regulatory landscape for water companies is intensifying. The Environment Agency is maintaining rigorous oversight of water utilities, ensuring their adherence to statutory drought plans. This heightened scrutiny includes more frequent checks on abstractors, enhanced monitoring protocols, and an expedited process for evaluating drought permit applications, all aimed at protecting public water resources while balancing environmental needs.

Further signaling a tightening regulatory environment, South West Water has submitted an application to Defra for a non-essential water use ban Devon. If approved, this measure would impose restrictions on certain business operations in Mid Devon, parts of East Devon, and Dorset. This potential ban highlights the immediate operational risks for commercial entities in these regions, necessitating proactive planning and compliance reviews.

The broader governmental response to the water crisis is also taking shape through the planned strengthened Water Bill UK. This forthcoming legislation is poised to introduce wholesale reforms within the water industry, with additional details expected in the coming months. These legislative changes, alongside the weekly coordination efforts of the National Drought Group, which includes Environment Agency representatives, underscore a concerted effort to address the systemic challenges facing the water sector.

The current water scarcity, particularly evident in the critically low Wimbleball Reservoir water levels, presents significant challenges for both public supply and environmental health. Joanne Laeger, the Environment Agency's area drought manager, has underscored that the arrival of autumn has not alleviated the drought, stressing the imperative to secure public water supplies while vigilantly monitoring environmental impacts. This situation demands a collective effort to optimize water usage, a responsibility that extends to every individual and organization.

For businesses, particularly those operating in Mid Devon, East Devon, and Dorset, the prospect of a non-essential water use ban Devon carries tangible operational and financial implications. Lawyers advising clients in these areas should therefore alert them to the potential for imminent restrictions, which could directly impact their daily operations and necessitate adjustments to water-intensive processes. The ongoing scrutiny of water companies and planned Water Bill reforms signal a tightening regulatory environment for the water sector, requiring proactive compliance reviews.

Looking ahead, the recovery of water resources hinges significantly on the upcoming winter's rainfall. While a changeable October weather forecast offers some hope, above-average precipitation in Devon, Cornwall, and the Isles of Scilly could potentially transition the region into a "fragile state of recovery" by April 2027. However, there remains a distinct possibility that the area could enter the traditionally dry months with a continued water deficit, emphasizing the long-term nature of this challenge and the enduring need for prudent water management practices.

Lawyers advising businesses in Mid Devon, East Devon, and Dorset should alert clients to the potential for imminent non-essential water use bans, which could impact operations. Furthermore, the ongoing scrutiny of water companies and planned Water Bill reforms signal a tightening regulatory environment for the water sector, requiring proactive compliance reviews.
