Drought planning stepped up amid potential hottest June on record

Plans to maintain water supply resilience have been discussed by a team of national experts, following a decline in reservoir and groundwater levels as well as river flows in parts of England as the UK faces the hottest June on record.
Chaired by the Environment Agency, the National Drought Group, which includes senior decision makers from the Environment Agency, the Government, water companies and key farming and environmental groups, met recently to discuss the current situation and action being taken to ensure there is a plentiful water supply over the coming months.
With climate change bringing more prolonged hot and dry weather conditions, as seen last month and so far this month, with lower-than-average rainfall across the South West, reservoir levels across the region have been unable to fully recharge ahead of the peak summer demand.
Colliford Reservoir, which dropped to around 15% last year, is currently around 2% higher than this time last year, while Roadford Reservoir currently has nearly 16% less water than the same time in 2022.
The natural environment is still recuperating from the impacts of last summer and the Environment Agency is also focusing ongoing efforts on monitoring how fish and invertebrates are recovering from drought. The group discussed how water companies must increase resilience to dry weather and encourage customers to reduce demand. This builds on the Government’s Plan for Water, which sets out measures to increase our resilience to drought and ease pressures on our water supply.
National Drought Group members heard that:
England has experienced potentially the hottest June on record, according to the Met Office, with temperatures soaring to 32.2°C on the hottest day;
the Environment Agency is clear that planning for increasingly extreme weather is essential in order for everyone to be prepared for the impacts these events cause: both drought and flooding;
water companies, retailers, regulators, as well as the agricultural and environment sectors, must prepare now as bouts of hot, dry weather become more consistent, and take forward improvements for managing and responding to future droughts;
all sectors are undertaking precautionary planning in the event that hot, dry weather continues into the summer, and continue to work closely together to support water supplies across the country;
the farming sector is working to improve drought resilience, to ensure water availability for the short and long term, helping overall food security.
Simon Hawkins, Chair of the National Drought Group and Director Operations South East and East at the Environment Agency, said: “The recent heatwave has served as a reminder that we need to prepare for weather extremes and act now to ensure resilient water supplies.
“The Environment Agency, water companies and partners are working collaboratively to handle drought risk across the country, with our staff managing abstraction licences to balance need, ensuring water companies implement their drought plans, working with farmers to manage resources and rescuing fish in areas where river levels are extremely low.
“We all have a role in easing pressures on our precious water supply to protect the environment, our wildlife and ensure clean and plentiful water for future generations.”
The Government’s Plan for Water brings together the significant action already taken, along with new measures, that will secure water supplies. This includes £2.2 billion of new, accelerated investment by water companies to spend on infrastructure to tackle pollution and increase our water resilience; a second £10m round of Water Management Grants to fund more on-farm reservoirs and better irrigation equipment; a new National Policy Statement on water resources so that key water supply infrastructure, such as reservoirs and water transfer schemes, can be built more quickly; and work to reduce water demand by encouraging water companies to consider how to rapidly increase smart meter installations for household and non-household customers.
Water Minister Rebecca Pow said: “I recently visited some of the key reservoirs in Devon and Cornwall to see how they, and local residents, have been impacted by the continuing drought conditions in the region.
“Through our Plan for Water, we are ensuring key water supply infrastructure such as reservoirs can be built more quickly, helping increase our resilience in the long-term.
“Whilst we all have a responsibility to protect this precious resource, water companies must step up their efforts to ensure water resilience. This includes not only increasing supplies but also reducing leakage and encouraging water efficiency to better deliver for both customers and the environment.”
As of Tuesday, 20th June, total reservoir stocks for England are at 83% of their total capacity. This year has seen a mix of exceptionally wet or very dry months, highlighting that we cannot rely on rainfall alone as climate change continues to make our weather patterns more erratic.
Devon and Cornwall are still suffering from drought despite average rainfall earlier this year. In August last year, South West Water implemented a Temporary Use Ban for the Colliford and Roadford regions (covering most of Devon and Cornwall), which remains in place.
South West Water’s Drought and Resilience Director, David Harris, said: “The impact of climate change has been intensified by population growth and tourism, and as a result our reservoirs are still not where we need them to be.
“That’s why we need customers, businesses and visitors in our beautiful region to continue to do their part and reduce their water use whenever possible. We are not asking customers to stop using water, we are asking that they use it responsibly.
“We have a plan in place, and this is working. So far, our interventions have already delivered results, boosting resources by around 25% in Cornwall, and around 12% in Devon.”
By 2050, we may need around four billion additional litres of water per day to meet future demand for public water supply, with experts warning that action on water resilience must be taken now to determine how these significant needs will be met.
South West Water is investing £125 million in its water resources to secure resilience through desalination solutions, installing new pipelines and repurposing quarries. By 2025, it aims to significantly increase its water resources by 45% in Cornwall and 30% in Devon.
