Drought planning and management
Information about how we manage and monitor water resources in Wales
A drought is a natural event that cannot be prevented. Every drought is different and each can have a different effect on people, businesses and the environment. Some droughts affect a large area while others are concentrated in a few catchments.
Proper use of water resources
Natural Resources Wales is responsible for ensuring proper use of water resources in Wales and for making sure there is enough water for all needs, including environmental needs. We achieve this by regulating the abstraction of water, monitoring the environment and by working closely with the water industry and other abstractors to manage resources.
Monitoring and drought permits
During droughts, we monitor and report on environmental impacts and monitor water companies' actions to confirm that they are respecting their drought plans. We also assess and adjudicate on drought permit applications. During a drought we work with water companies and others to manage effects on people, businesses and the environment.
Our drought plan
Natural Resources Wales produces a drought plan which describes the indicators we currently use to classify the different stages of drought. Droughts are complex and can be measured in a range of ways. They also affect different elements of the environment and water users in different ways.
Our drought plan provides a flexible framework for dealing with different drought events and is an operational manual for drought teams operating within Natural Resources Wales. It covers the key decisions and actions that our teams make and carry out to detect the onset and end of droughts and to manage impacts during a drought period.
Preparing for drought
We update our drought plans annually. We also undertake drought exercises to make sure we are ready for drought. These exercises are based on information from historic droughts and also serve to put the actions in our plans to the test. We work to ensure that our external communications during a drought period provide clear and detailed descriptions of how and where the drought is developing, what its effects are and what the future risks might be.
Drought in European designated sites
Where actions in our drought plan could have an impact on European designated sites (Special Areas of Conservation or Special Protection Areas), we will undertake a Habitats Regulations Assessment to determine if our actions are likely to affect the site. If we consider likely effects to be significant, or if they cannot be determined, we will complete an appropriate assessment.
NRW drought orders
We can apply for a Natural Resources Wales drought order if the environment is suffering serious damage as the result of abstraction during a drought. We will only apply for environmental drought orders if they prove necessary. For example, a drought order was granted in Wales during the drought of 1995/96 to reduce discharges from Llyn Celyn from summer compensation levels to winter compensation levels. This measure was introduced to build up an increased bank of water for use in protecting the environment.
Water companies' drought plans
Water companies have a statutory duty to prepare, consult, publish and maintain a drought plan. These plans show how the water undertaker will supply water to customers during periods of low rainfall, when water supplies become depleted and how adverse effects during droughts will be minimised.
Water companies are required to conduct consultations about their plans and we are a statutory consultee on draft plans. We respond to these by producing a formal representation.
Natural Resources Wales has produced a water company drought plan technical guideline (for a water company wholly or mainly in Wales) to follow when preparing a drought plan. The document is available here: water company drought plan technical guideline.
The Welsh Government’s guiding principles for developing drought plans for water companies wholly or mainly in Wales have been published separately to this guideline. The guiding principles set out the drought plan statutory process and policy expectations. The Water companies should refer to the guiding principles in-conjunction with our guideline when preparing their drought plan.
If a water company is wholly or mainly in England, with sites that affect Wales, they will need to follow Defra and the Environment Agency’s water company drought plan guidance when developing their plan. When developing the content of their environmental assessments, environmental monitoring plans, Strategic Environmental Assessment (SEA) and Habitats Regulations Assessment (HRA) for drought management actions located in Wales, they should refer to our guideline. In particular, they will have to consider their obligations in relation to the Environment (Wales) Act 2016 and Well-being of Future Generations (Wales) Act 2015 for these sites.
Working with partners
We have consulted with the Welsh Government, the Environment Agency, Ofwat, Natural England and water undertakers in Wales when producing this guideline.
After receiving responses to the consultation, water companies must then produce a statement of response, setting out how they have dealt with the representations received. Natural Resources Wales provides advice to the Welsh Government about responses from water companies that are wholly or mainly in Wales. The Welsh Government may request a hearing or inquiry, or direct the company to publish its final plan.

Private Water Supplies
Groundwater levels are fed by rainfall. Usually groundwater levels increase during winter and reduce through the summer. It can take some time for groundwater levels to increase in response to rain as water has to wet up the soil and then travel through the ground and into the spaces between rocks further underground. When there is a lack of rainfall over a long period groundwater levels can become exceptionally low and there may be impacts on private water supplies such as spring sources drying up or pumps running dry.
- If water levels are very low take action to seek an alternative supply of water. Speak to neighbours to find out if they can supply you should your source of water dry up. If you use this option you should ensure that containers used to transfer water are cleaned and disinfected to prevent contamination. Guidance can be found on the prevention of contamination on the DWI website or the WRAS website
- Find out if there is a mains supply nearby that you could connect to for a backup water supply. Contact your water company or local council for more information
- The Drinking Water Inspectorate (DWI) has further information about regulations surrounding alternative water supplies in emergencies. This information also covers the roles and responsibilities of the local authority and local water company with respect to private water supplies in more detail
Applications for permits and drought orders by water companies
Water companies can apply for drought permits or orders to help maintain public water supplies or protect the environment where there has been an exceptional shortage of rain. Information can be found on the how to apply for drought permits and orders page.
Applying for drought permits (to Natural Resources Wales)
Drought permits are granted in Wales by Natural Resources Wales and in England by the Environment Agency.
Applying for droughtorders (to Welsh Ministers / Secretary of State)
Drought orders are granted in Wales by Welsh Ministers and in England by the Secretary of State.
If granted, drought permits or orders allow water companies to:
- Abstract more water
- Reduce other abstractions
- Restrict certain types of water use
Drought orders also permit Natural Resources Wales / Environment Agency to modify, restrict or stop abstractions in order to protect the environment.
Wales Permitting Centre
The Wales Permitting Centre (WPC) within Natural Resources Wales deals with water company drought permit applications and responds to ministers about drought order applications in Wales.
When dealing with drought permit and order applications, we follow the guidance available in the joint Welsh Government, Natural Resources Wales, Defra, Environment Agency guidelines.
