We are developing and delivering the Reservoir Safety Reform Programme, in response to the recommendations set out in the Independent Reservoir Safety Review Report, led by Professor David Balmforth.
In a Written Ministerial Statement in July 2022 the Government set out its intention to reform reservoir safety management practices and modernise the Reservoirs Act 1975.
The Reservoir Safety Reform Programme will be delivered in a phased way over several years, by the Department for Environment, Food and Rural Affairs (Defra) and the Environment Agency (EA). We will use this information page to keep you updated on our plans and progress.
Reservoir safety is about ensuring the physical structure of a reservoir, its dams and embankments are safe. In England, around 2.2 million people are potentially at risk from reservoir dams failing and causing flooding which could endanger life.
We have an excellent reservoir safety record. However, the Toddbrook incident in 2019, increasing demands on water supply, and the impacts of climate change, are all reasons to re-evaluate how we regulate reservoir safety.
Our vision is to create a safety regime for reservoir dams in England which protects our communities, by making us ready for and resilient to climate change – today, tomorrow and the future. We will do this by:
Strengthening the roles and responsibilities for reservoir owners, operators, engineers, and the regulator (EA).
Improving the safety practice and culture, through a programme of continuous development of skills, capacity and training across the reservoir community.
Modernising legislation and safety management practice to ensure a robust and proportionate safety regime that is fit for the future.
Engaging with stakeholders to help shape our approach and deliver reforms.
The Toddbrook incident and Professor Balmforth’s independent reservoir safety review.
Climate change - which is increasing the pressures on reservoir infrastructure and demand for reservoirs and water resources.
The need to update the 1975 Reservoirs Act to bring it in line with modern safety management practice in other sectors.
The declining numbers of reservoir engineers and the increasing demand for specialist engineers in future.
We have worked with reservoir owners on emergency flood plans for all large, raised reservoirs. It is now a legal requirement for reservoir owners to produce and maintain on-site emergency flood plans. As of December 2022 all large, raised reservoirs are compliant. The requirement is notified to new owners when their reservoirs are registered.
We have been revising, updating and publishing reservoir flood maps for almost 2,000 large, raised reservoirs. Through this work we have ensured accurate information is available for emergency planning.
We have created a dedicated page on gov.uk for reservoir safety guidance documents. We hope this will make finding the guidance you need easier. We have already developed and published new guidance to support engineers and owners. This will ensure all inspections by supervising and inspecting engineers are systematic, detailed, and impartial. We also published new research into spillway design, examination and failure mechanisms.
We commissioned the Institution of Civil Engineers to review how we safeguard the future supply of reservoir engineers. The report was published in February 2023. The recommendations made in the report will be taken forward alongside the reform programme.
Reservoir safety policy is devolved. The reform programme is focussed on England. The devolved administrations will decide whether and how to implement changes in their countries. We are working closely with the devolved administrations to share knowledge and help ensure a coherent approach to reservoir regulation across the UK.
Overall roles and responsibilities
Responsibilities for reservoir safety regulation are divided between the following three communities, which together ensure almost 2.2 million people in England, who live near reservoirs, are not put at any unnecessary risk of flooding, which could endanger life:
Reservoir owners and operators, who are responsible for the safety of their reservoirs. They must appoint engineers from the reservoir panels of engineers to inspect their reservoirs and they must act on the engineer’s recommendations.
Reservoir panel engineers, who are appointed to supervise and inspect reservoir construction and operation.
The Environment Agency manages and enforces reservoir safety regulation in England.
The reform programme aims to strengthen and modernise safety procedures. It will not change this overall three way approach, but will mean some changes for all of these communities.
Our programme of reforms to strengthen and modernise the regime will be implemented through a combination of guidance, secondary legislation and new primary legislation, when parliamentary time allows.
We are currently reviewing the definition of large, raised reservoirs to ensure that the regulatory requirements apply to the right set of structures and features.
We have commissioned work to develop a new hazard classification which better reflects the level of risk from reservoir failure, and the arrangements for how it would operate. This includes looking at good safety management practice in other countries and sectors. The project will involve stakeholders in shaping the details of the classification and what that could mean in practice for reservoir owners and engineers. In the current system reservoirs are classified as either high risk or not high risk. The aim is to have an approach with more hazard classes and so greater scope for differentiation in how reservoirs are regulated. Reservoirs which are in the higher hazard classes would be subject to more regulatory requirements and those which are in lower hazard classes would have fewer requirements.
We are currently surveying reservoir owners and engineers to identify the locations of small, raised reservoirs across England (i.e. reservoirs which are capable of holding 10,000 -25,000 m3 water above ground level). We have created a briefing note, which explains our work in more detail and may be able to answer some of your enquiries. Gathering information about existing structures is a key step in determining whether such reservoirs should be regulated. The information will help us assist with developing proposals for the new hazard classification. If you believe you have a small raised reservoir on your land, please complete the form or email the details to reservoirs@environment-agency.gov.uk.
We are working closely with the Institution of Civil Engineers (ICE), and their new Panel Engineers Committee, on actions to increase the capacity and capability of supervising and inspecting engineers across England. These actions stem from recommendations in Professor Balmforth’ s independent reservoir safety review and the Future Supply of Engineers Report.
The changes will offer a range of benefits to the engineering community, for example:
Bringing more engineers into the industry, through a recruitment programme to encourage graduates into reservoir engineering careers. This will reduce the burden of work currently experienced by both supervising and inspecting engineers, and ensure we have enough resource for future demand.
Supporting the career progression of panel engineers. We will align their career path to the new hazard risk classifications and provide them with the additional learning and development opportunities they need to succeed.
Securing the quality and standards of all inspection reporting and monitoring, carried out by panel engineers, through the creation of a capability process. Working with Defra and the Welsh Government ICE have published the Reservoir Pannel Engineer Capability Process. This process monitors the capabilities of engineers, identify gaps in knowledge and provides training where needed, to continually improve the technical knowledge and expertise provided by engineering panels. A letter has been sent informing all engineers about this new process.
We have published guidance on Reservoirs: owner and operator requirements, to explain what you have to do if you own or operate a reservoir, or intend to build one. In addition, we have also produced a ‘Quick guide to the Reservoirs Act for Owners and Operators’ as an introduction of "how" to operate a reservoir. This guide highlights key activities you should be doing at your reservoirs, information about different types of reservoirs and what to look out for on your dam. This is a new document, and we would welcome any feedback from you. Please contact us at reservoirs@environment-agency.gov.uk.
The reservoir safety review identified the need to improve how we as an industry manage, plan for and learn from incidents. The Environment Agency is updating the incident reporting system as a first step to improving incident response.
The new reporting system will allow the recording of “near miss” incidents which will create a more comprehensive classification system and develop understanding of what constitutes a ‘near miss’. We will be able to collect, analyse and share data which will help identify common themes and recurring issues, where improvements can be made.
Professor Balmforth recommended we introduce anonymous reporting of incidents. We will investigate how we might achieve this and will contact reservoir owners and engineers to gather their thoughts on this topic in the future.
The Reservoir Safety Review recommended that the Environment Agency should have the powers to question and challenge supervising engineers’ annual statements, inspecting engineers’ reports, risk assessments and reservoir management plans. These new duties will improve the quality and consistency of engineer reports and provide an ongoing national assessment, to help develop guidance and training.
As part of the Reservoir Act Compliance Enforcement project, we are currently reviewing how annual statements (Section 12s) are created and submitted. We are currently trialling a new process to gather feedback from engineers and undertakers. The proposed service would allow supervising engineers to access an online system and download an annual statement template which will be prepopulated. This change is part of the Environment Agency’s shift to digital-by-default. We hope the new system will improve consistency in statements and make the administration process for statements more streamlined.
We have reviewed two sets of existing reservoir safety regulations under the Reservoirs Act. There is a requirement to review them every 5 years to check how these are operating and whether they remain fit for purpose. The Post Implementation Reviews can be found here:
The reviews recommend retaining the regulations and have identified some areas where the regulations can be improved. These are being included within the reservoir reform programme and proposals for changes to the regulations will be consulted on.
We are trialling a new process to gather feedback from engineers and undertakers on how annual statements (Section 12s) are created and submitted. If you are interested in being involved, or have any questions on this project please contact reservoirs@environment-agency.gov.uk quoting “RACE2 Digital Project”.
If you believe you have a small raised reservoir, please complete this survey to help us identify small, raised reservoirs across England.
We will be engaging regularly with the industry and professional bodies such as Institution of Civil Engineers (ICE), National Farmers Union (NFU), Association of Drainage Authorities (ADA) etc. We encourage you to share your views with your representative body so that they can represent your interests in shaping the reforms.
The programme will be delivered over several years through new secondary legislation, guidance, and primary legislation (when parliamentary time allows). Timings are provisional and may change as the programme progresses. The details of what will be included in each legislative stage may change.
