1. Executive summary
This report is a review of reservoir compliance and enforcement of the 2,117 large raised reservoirs (LRRs) in England. It covers the period from 1 January 2021 to 31 December 2022.
It includes:
- work done by the Environment Agency’s National Reservoir Safety Team to protect the public
- actions taken to ensure compliance with the Reservoir Act 1975
- data on reservoir registration, compliance and enforcement actions taken
The COVID-19 pandemic of 2020 and 2021 changed working practices across England. We worked hard to keep the public safe from reservoirs at all times. We kept non-compliance figures low.
The reservoir safety industry learnt many lessons from the incident at Toddbrook Reservoir in 2019. Government commissioned 2 independent reports by Professor David Balmforth and accepted his recommendations for improving the reservoir safety regime. You can read more about this in appendix 2.
All registered LRRs must now have an onsite flood plan. These explain what to do at the site in the event of an incident.
In April 2021, a ministerial direction gave reservoir undertakers one year to have an onsite flood plan certified by a panel engineer. On 31 December 2022 all operational reservoirs in England met this requirement.
Over the last 2 years, reservoirs have been well managed by their undertakers. There have been no significant incidents resulting in loss of life or the total failure of a dam or reservoir.
Weather extremes are increasing due to climate change. Our infrastructure is also aging. It is increasingly important that we manage the safety of England’s reservoirs to the highest possible standard.
We are:
- working to improve and share knowledge to help with this
- carrying out research
- regularly working with national and international partners
2. Background
Reservoirs in England have a good safety record. The last reservoir failure that led to loss of life in England was more than 100 years ago. Twenty-one people died after the failure of 2 dams in North Wales in 1925. This tragedy led to the passing of the Reservoir (Safety Provisions) Act 1930.
Parliament updated and superseded this act with the Reservoirs Act 1975 (the Act). Parliament amended this later act by means of the Flood and Water Management Act 2010.
The Water Act 2003 transferred the responsibility for enforcing the Reservoirs Act 1975 in England and Wales from local authorities to the Environment Agency. On 1 April 2013, Natural Resources Wales (NRW) became the enforcement authority for LRRs in Wales. We (the Environment Agency) remain responsible for LRRs in England.
Although the safety record in England is good, we cannot become complacent. The risk from reservoirs is significant. Reservoir operators and owners (undertakers) are responsible for making sure their reservoirs are safe.
Our role, as the regulator, is to make sure that undertakers follow the legal safety requirements of the Act. We follow the Regulators Code, which means we regulate in a consistent, fair and risk-based way.
3. Our role
We, the Environment Agency, track compliance at all LRRs in England. Natural Resources Wales does this in Wales. The Scottish Environmental Protection Agency (SEPA) regulates according to the Reservoirs (Scotland) Act 2011.
As the regulator, we must:
- maintain a register of all reservoirs
- make sure that undertakers follow the Act by monitoring compliance and engaging with them
- make sure that undertakers appoint a construction engineer - their role is to supervise the construction, alteration, discontinuance or abandonment of LRRs
- make sure that undertakers have emergency onsite flood plans in place for their reservoirs – these must set out the actions they would take to control flooding in the unlikely event of a reservoir emergency
- designate reservoirs as ‘high risk’ if an uncontrolled release of water from the reservoir could endanger human life
- make sure that undertakers appoint a supervising engineer for their high risk reservoirs
- make sure that undertakers have their high risk reservoirs inspected by inspecting engineers
- make sure undertakers carry out any safety measures recommended by inspecting engineers
- appoint engineers and commission safety work when an undertaker does not comply with the Act - we charge undertakers for this
- appoint engineers and take any other action necessary in an emergency - we charge undertakers for this
- make sure that undertakers report reservoir incidents and share lessons learnt from them
- make sure that we observe and follow the requirements of the Act for our own reservoirs
Our role extends beyond monitoring the compliance of LRRs.
We also:
- take enforcement actions on undertakers who fail to comply with the Act, when it is appropriate to do so
- work with undertakers to provide advice and guidance so they can operate their reservoirs safely
- engage with the British Dam Society (BDS) and Institution of Civil Engineers (ICE) to improve knowledge and capability in the industry
- work with Department for Environment, Food and Rural Affairs (Defra) on the review and reappointment of engineers
- advise Defra on operational implications of policy
- lead and inform research and development projects
- work with international partners to share knowledge and lessons learned to improve our own practises
- commission and maintain reservoir flood maps for all operational reservoirs, for emergency planning and risk assessment purposes
- contribute to legislative reviews and improvements
We operate 219 of the 2,117 reservoirs in England for flood risk and water management purposes. This is done by our area teams and overseen by 25 different supervising engineers. We do this to keep our operational and regulatory roles separate.
Sixteen of these 219 reservoirs are under the supervision of an independent construction engineer. These reservoirs are either being built or altered.
4. Our activities
We have achieved many of the objectives set out in the 2019 to 2020 biennial report.
4.1 Communication
We have introduced account managers to improve communication with the industry. They act as a single point of contact to major undertakers.
Account managers have helped to:
- make communication easier when discussing non-compliance
- ensure roles and responsibilities are well understood
- improve the relationships we have with the reservoir community
We are also investigating how we can reach stakeholders who may not have previously needed to know the details of the Act. We are doing this through our reservoir safety reform programme.
We want to continue to find ways of improving communication and outreach with:
- undertakers
- engineers
- the industry
We have listened to feedback that it can be difficult to communicate with us.
We will introduce a digital service in 2023 which will make updating details and communicating with us easier. This is a phased project which will allow supervising engineers to submit their annual statements online. Other submissions will be included in future updates.
We continue to work with BDS and ICE.
This includes:
- attending events and working closely with the new reservoirs committee
- using their input to shape change
- considering ideas from all stakeholders in any changes made
- increasing our outreach to share knowledge and provide advice across the country
We are also working to increase awareness of the Act, our role and how this improves public safety. We hope this will continue to improve the standards of reservoir safety management. It will also help us reach people and groups who may not have previously been aware.
We have developed our relationships with international partners and shared experiences and lessons learned. We continue to work closely with the devolved administrations in the United Kingdom.
4.2 Guidance
The 2019 Toddbrook incident review report made several recommendations to improve guidance. We published 7 new documents in 2022.
There are 3 technical guides for engineers and specialists on:
There are also 4 new guidance documents for engineers and undertakers:
- Reservoir owners and operators guidance: inspection information pack
- Reservoir inspecting engineers: inspecting high-risk reservoirs
- Reservoir owner and operator guidance: spillways
- Reservoir supervising engineers: written statements and site visit reports
4.3 Flood maps
We published updated reservoir flood maps on 9 November 2021. These help emergency responders make better informed decisions when managing reservoir incidents.
The new maps now have 2 flood extents.
These are wet and dry day scenarios:
- a wet day map shows what may flood if the reservoir failed at the same time as the rivers were already extremely flooded
- a dry day map shows what will flood when the rivers are not in flood.
You can see the updated maps on the publicly available check the long term flood risk for an area in England service. You can download them from data.gov.uk.
We also published a reservoir flood maps when and how to use them guidance page.
This is for:
- spatial planners
- developers
- reservoir owners
- engineers
We will publish maps for reservoirs which have been completed after 2016 in the next 2 years. As part of our continual improvement, we are aiming to introduce a rolling programme of reservoir flood mapping. This would mean that future reservoirs are mapped when they are built, after we receive the construction report.
4.4 Onsite flood plans
The Toddbrook incident highlighted the importance of having an onsite emergency flood plan. Defra issued a ministerial direction on 12 April 2021 that all LRRs must have a certified onsite flood plan. This must be tested regularly.
On 31 December 2022, all operational LRRs in England met this requirement. You can read more about onsite flood plans in Appendix 1.
Government commissioned Professor David Balmforth to independently review the Toddbrook incident and England’s reservoir safety regime. His 2 reports were published in March 2020 and May 2021 respectively.
Professor Balmforth made 15 recommendations in his May 2021 independent reservoir safety review report. Government accepted these recommendations in a ministerial statement on 20 July 2022.
We are working with Defra to carry out these recommendations in a reservoir safety reform project. You can read more about these recommendations in Appendix 2.
5. A risk-based approach to enforcement
The main causes of non-compliance are where an undertaker has not:
- appointed a supervising engineer to oversee ongoing safety
- appointed an inspecting engineer to carry out the statutory inspection
- completed safety measures identified by the inspecting engineer by the date specified in the inspection report
We continue to focus on reservoirs which pose the greatest risk to public safety. Our main priority is to make sure reservoirs have the correct supervision and that safety works are carried out when required. We make sure that reservoirs always have a construction or supervising engineer appointed. Not having an engineer appointed at the right time poses a significant risk to the safety of that reservoir.
A construction engineer supervises a reservoir when it is being built or altered. They will issue a final certificate when the work is completed. The undertaker must then appoint a supervising engineer.
A supervising engineer supervises a high-risk reservoir once it has been built and is in operation. This is a continuous appointment. They visit the reservoir and write an annual statement for the undertaker.
This statement includes the actions:
- they have taken to monitor the reservoir
- the undertaker has taken to maintain the reservoir
The supervising engineer is the most important contact if an issue arises at a reservoir.
The undertaker must employ an inspecting engineer to carry out a statutory inspection of a high-risk reservoir at least once every 10 years. This is not a continuous appointment.
The inspecting engineer produces a report and directs the undertaker to carry out any required safety measures. These will have deadlines which the undertaker must meet. The inspecting engineer must certify when any measures are completed.
We provide:
- advice and support about complying with the Act when asked
- advice and guidance on how to comply with the Act if a non-compliance offence is committed
We do this in writing or by meeting the undertakers. If the offence persists or is serious, we will escalate and take formal enforcement action. When we do this, we follow the Regulators Code. We apply the following principles:
- act proportionately
- be consistent
- be transparent
- target enforcement action
- be accountable
5.1 Risk designation
We assign a risk designation to each LRR in England. The designation level is based on risk to life in the event of an uncontrolled release of water from the reservoir.
There are 2 designation levels:
- high-risk
- not high-risk
High-risk reservoirs must fulfil all the requirements of the Act. There are also some specific elements which ‘not high-risk’ reservoirs must fulfil.
LRRs which are classed as ‘not high-risk’ do not need a:
- supervising engineer appointed
- statutory inspection
Undertakers must still register the reservoir and report any incidents. They should inform us if anything changes on site or downstream which might alter the risk designation. These changes could include property developments downstream or alterations to the reservoir.
We provide a risk designation once we receive a final certificate from a construction engineer.
There may be reservoirs which do not yet have a risk designation. This can happen where they have been newly constructed or recently altered. If an undertaker has requested a review or appealed a risk designation, a provisional designation will be in place.
Table 1 shows the risk designation status of large raised reservoirs in England.
Table 1: reservoir risk designation status
| Status on 31 December 2022 | Number of reservoirs |
|---|---|
| Reservoirs under construction or alteration | 130 |
| Reservoirs under construction (before designation) | 116 |
| Provisional high-risk | 13 |
| High-risk (including provisional) | 1699 |
| Not high-risk | 293 |
| Not yet determined | 125 |
| Reviews of designation | 4 |
| Appeals of designation | 0 |
Of the 130 reservoirs under construction:
- 20 have a preliminary section 7(1) certificate – this confirms that the reservoir has reached a stage of construction where it can be wholly or partially filled with water
- 110 are not yet ready to be filled with water
5.2 Reservoir information
Table 2 shows the number of engineering activities at LRRs.
Table 2: reservoir information recorded between 1 January 2021 and 31 December 2022
| Reservoir information recorded | Number of reservoirs |
|---|---|
| Number of supervising engineers appointed by or on behalf of the undertaker | 477 |
| Number of certificates issued after the satisfactory completion of an inspection under Section 10 of the Act | 298 |
| Number of these certificates which contained measures to be taken in the interests of safety | 168 |
| Number of Section 10(6) certificates showing that measures to be taken in the interests of safety had been satisfactorily completed | 176 |
56% of Section 10 inspection certificates contained safety measures. This is an increase from 39% in 2019-2020. The number of section 10(6) certificates is higher than the number of certificates after an inspection. This is because deadlines to complete measures can be more than 1 to 2 years.
Table 3 shows the number of reservoirs owned by each type of undertaker
Table 3: total number of reservoirs by undertaker type
| Undertaker type | Number of reservoirs | % of total number of reservoirs |
|---|---|---|
| Water companies | 664 | 31.4 |
| Private landowners and trusts | 346 | 16.3 |
| Farms | 327 | 15.4 |
| Environment Agency | 219 | 10.3 |
| Local authority | 173 | 8.2 |
| Industrial and commercial | 114 | 5.4 |
| Canal and Rivers Trust | 70 | 3.3 |
| National Trust | 44 | 2.1 |
| Registered charities | 42 | 2.0 |
| Recreational clubs and associations | 42 | 2.0 |
| Other government agencies and departments | 40 | 1.9 |
| Other/unknown | 19 | 0.9 |
| Fish farms | 9 | 0.4 |
| Universities, colleges and schools | 7 | 0.3 |
There were 21 newly constructed reservoirs recorded between 1 January 2021 and 31 December 2022. Of these, 20 had a preliminary section 7(1) certificate.
Table 4 shows which undertaker types have constructed new reservoirs.
Table 4: information on newly constructed reservoirs by undertaker type
| Undertaker type | Number of reservoirs |
|---|---|
| Registered charities | 2 |
| Environment Agency | 5 |
| Farms | 3 |
| Local authority | 3 |
| Private landowners and trusts | 2 |
| Water companies | 2 |
Table 5 shows the risk designation of newly constructed reservoirs.
Table 5: breakdown of risk designations of newly constructed reservoirs
| Undertaker type | Not yet determined | High risk | Provisional high risk | Not high risk |
|---|---|---|---|---|
| Registered charities | 1 | 0 | 0 | 2 |
| Environment Agency | 1 | 4 | 0 | 0 |
| Farms | 0 | 2 | 1 | 0 |
| Local authority | 3 | 0 | 0 | 0 |
| Private landowners and trusts | 1 | 0 | 3 | 0 |
| Water companies | 0 | 3 | 1 | 0 |
5.3 Compliance figures
High-risk reservoirs must have a supervising engineer appointed at all times. The number of reservoirs without a supervising engineer has decreased over the last 6 years.
In 2017, there were 8 reservoirs with no supervising engineer. This decreased to 2 by 31 December 2022. There was a slight increase in 2020, probably due to restrictions in place during the COVID-19 pandemic.
As of 31 December 2022, there were 5 reservoirs with an inspection due, but no inspection engineer appointed. Of those 5, all have a supervising engineer appointed. There were also 10 reservoirs with an inspection overdue by more than a year, but with an inspecting engineer appointed.
We have included reservoirs where the inspection has taken place, but we have not yet received the report. The Act allows 6 months for an engineer to finalise their report. This contributes to the higher non-compliance figures because we do not know the date of the inspection until we receive the report. The overdue dates will then be updated. Non-compliance with inspections has decreased in the last 6 years.
On 31 December 2017, 13 reservoirs had an inspection due with no engineer appointed (3 on 31 December 2020). Eleven had an inspection overdue by more than a year but had an engineer appointed (5 on 31 December 2020).
We issue a formal notice when an undertaker fails to appoint an inspecting engineer by the inspection due date. Undertakers must then appoint an engineer within 28 days.
There were 56 reservoirs with outstanding safety measures. This is a decrease from 65 on 1 Jan 2021. This is shown in table 6.
Table 6: non compliances from 1 January 2021 to 31 December 2022
| Non-compliance status | Situation on 1 January 2021 | Situation on 31 December 2022 |
|---|---|---|
| Number with no supervising engineer appointed | 5 | 2 |
| Inspection due, and no inspecting engineer appointed | 3 | 5 |
| Section 10 inspection overdue by more than a year, but an inspecting engineer has been appointed | 5 | 11 |
| Measures in the interests of safety that have not been completed by the deadline set by the inspecting engineer | 65 | 56 |
| Reservoirs in operation with no onsite flood plan | Not applicable | 0 |
Until we give notice of a final high-risk designation, the provisional risk designation may change. In these figures, the risk designation is not final for:
- 2 reservoirs with no supervising engineer appointed
- 3 reservoirs with outstanding safety measures
- 11 reservoirs with an inspection overdue by more than a year but with an inspecting engineer appointed
5.4 Serving enforcement notices
We may serve an enforcement notice if an undertaker does not comply after advice and guidance is given.
We will serve formal notice if an undertaker does not appoint an engineer when required and after reminding. The undertaker must then make the appointment within 28 days.
If an undertaker does not complete safety measures by a given deadline we will take several steps.
We will:
- ask the undertaker why they have not completed the measures
- issue a formal notice for completion of the measures if there is no response
- Issue a final warning letter if they miss the notice date
If the breach is significant and there are no reasonable mitigating circumstances, we may prosecute. We served a total of 51 notices in this reporting period. Of these, 32 cases are now compliant. Table 7 shows the number of notices served between January 2021 and December 2022.
Table 7: number of notices served 1 January 2021 to 31 December 2022
| Section of the Act | Non-compliance | Number of notices served |
|---|---|---|
| Section 10(7)(a) | Failure to appoint an inspecting engineer | 2 |
| Section 12(4) | Failure to appoint a supervising engineer | 5 |
| Section 10(7)(b) | Failure to complete safety measures by stipulated deadline(s) section 10(3) | 19 |
| Section 17(1)(e) | Powers of entry | 11 |
| Section 8(1) | Failure to appoint a construction engineer | 1 |
| Section 21A | Power to require information | 12 |
| Section 16(1) | Emergency powers | 1 |
The number of outstanding safety measures in Table 6 is higher than the number of notices served in Table 7. This is because overdue measures do not always need a notice to encourage an undertaker to comply. Often, the non-compliance can be fixed with advice and guidance.
Table 8 shows the number of notices served by undertaker type.
Table 8: number of notices served by undertaker type
| Served Notices per Undertaker Type | Total to record |
|---|---|
| Industrial and commercial | 10 |
| Local Authority | 7 |
| Farms | 5 |
| Private landowners and trusts | 17 |
| Recreational clubs and associations | 8 |
| Other | 4 |
5.5 Other enforcement action
We may issue a written warning if an undertaker is still non-compliant after the notice deadline. We issued one of these warnings for overdue safety measures between January 2021 and December 2022.
We also issued 48 written warnings for reservoirs which did not hold certified flood plans by the deadline. They are now all compliant.
We are currently investigating 51 reservoirs and may take enforcement action depending on the results.
We apply a risk-based approach to achieve the right outcome for safety. This means we have used our professional judgement to take appropriate action. That action could be to issue advice and guidance or could go as far as carrying out emergency works. We carried out emergency works at one reservoir between January 2021 and December 2022.
We take this approach so that we can achieve safe outcomes in line with the Regulators Code. It is not always appropriate for us to take punitive enforcement action if a reservoir becomes non-compliant.
5.6 Local enforcement position
During the COVID-19 pandemic, we developed a temporary Local Enforcement Position (LEP) to account for any potential difficulties in carrying out safety works. Our priority remained protecting people downstream of reservoirs. To keep the public safe, we expected undertakers and engineers to comply with the Act despite COVID-19 restrictions.
We carefully considered each case which applied for a LEP. We did not grant LEPs to all cases. In some cases, we advised the undertaker to make alternative arrangements to comply with the Act. We granted 19 LEPs, giving specific conditions in each case. These granted extensions for up to 3 months. Undertakers had to ensure suitable mitigating action was taken to ensure the dam remained safe throughout the works. We are no longer accepting LEPs for COVID-19.
5.7 Environment Agency reservoirs
We are the undertaker for 219 LRRs in England.
There was one case of non-compliance at one of the reservoirs we operate. We sent a letter of warning to the relevant director of operations. The non-compliance related to overdue measures in the interest of safety. It is now compliant.
5.8 Incident reporting
Undertakers must report any reportable incidents which happen at their reservoir. A reportable incident is “an incident which results, or could result, in the uncontrolled release of water from a large raised reservoir.”
This also includes where “measures have been taken to prevent any or any further uncontrolled release of water and to minimise the danger to human life”.
We use this information to improve safety by:
- investigating incidents where appropriate
- informing the industry of any trends and important lessons identified
- contributing to research into reservoir safety and incident analysis
We publish detailed information in our annual post incident report. This means those involved in reservoir safety can learn from past incidents.
Reporting is only mandatory for incidents at large raised reservoirs. We encourage undertakers to report incidents at small raised reservoirs on a voluntary basis.
Table 9: reported incidents
| Reported incidents | 2013 to 2020 | 2021 to 2022 |
|---|---|---|
| Incidents at large raised reservoirs | 69 | 19 |
| Incidents at small raised reservoirs | 5 | 3 |
| Total number of reported incidents | 74 | 22 |
Incident reporting became mandatory in 2013. Since then, an average of 8 incidents have been reported each year.
We expect that the number of incident reports may increase in the future. This is not necessarily because more incidents are happening. Instead, we expect to receive more reports as the reporting culture improves.
We are working to raise awareness of the benefits that incident reporting brings. We continue to encourage undertakers to report all incidents, and near misses. We have not taken enforcement action to get incident reports, although we have issued reminders to undertakers where a report is due. Compliance with the regulations on incident reporting is generally seen to be good and improving.
6. The future
Carrying out the reservoir safety reform programme will lead to a lot of change over the next few years. Protecting the public and keeping reservoirs safe remains our utmost priority. We will continue to monitor compliance and enforcement as these changes take place.
You can read more about the reform programme in appendix 2.
We have increased the number of people working in our reservoir safety team. This means we can increase the scope of the priority activities which we regulate.
From 2023, we will be reporting on, and enforcing where appropriate:
- offences under section 11(2) – keeping and updating the prescribed form of record
- offences under section 10(5A) – maintenance measures
- offences under section 4(1) – registration of large raised reservoirs
Section 11(2) requires undertakers to maintain a prescribed form of record for high-risk reservoirs. Undertakers must fill them in as directed by the Act and an inspecting engineer in a section 10 report. We will start enforcement action if the records are not maintained as directed.
An inspecting engineer can recommend measures “as to the maintenance of a reservoir” which an undertaker must carry out. The inspecting engineer writes these in the section 10 inspection report. They are not the same as measures in the interests of safety.
After construction, the construction engineer provides a final certificate for a reservoir. The undertaker has 28 days to formally register the reservoir. Schedule 1 (paragraphs 1 to 7) states the information required. We will now ask that this information is provided. We will record failure to supply this information within 28 days of the final certificate as a non-compliance.
We have introduced a new sub-team to support the recommendation to increase the regulatory role and powers of the Environment Agency. This team will be dedicated to assessing the standards of submissions. We will employ panel engineers to review engineer’s submissions.
This team will also provide expert advice and guidance to undertakers and engineers.
We will:
- use the ongoing quality assessment to update guidance and provide training
- work with the industry to make expectations clear and encourage good management practices
6.1 Reporting
We will be changing the way we manage incident reporting.
This includes:
- updating the incident reporting forms
- changing the way we share lessons learned
- changing the incident categories to capture more accurate data
- encouraging near miss reporting
We hope this will increase outreach and improve how we can use this data to analyse trends. It will make it easier for the public and other interested parties to learn from incidents and allow more targeted research. Together, these actions will continue to improve reservoir safety.
In 2023, we will offer a programme where owners of small raised reservoirs can voluntarily provide information about their reservoirs to us. This is to ask owners to help us look into what reservoirs exist.
We hope that by 2024 we will have enough information for Defra and government to determine whether changes to legislation are required. This would be for reservoirs under 25,000 cubic metres capacity.
7. Appendix 1: onsite flood plans
On 12 April 2021, ministers issued a direction to undertakers regarding LRRs in England. This states that all operational LRRs must have and maintain an emergency onsite flood plan.
This applies if the reservoir is:
- designated high-risk
- designated not high-risk
- under construction
If the reservoir is under construction, an engineer must certify the flood plan before they issue the preliminary certificate.
Undertakers needed to prepare the plans, and have a qualified civil engineer certify them within 12 months of being notified about the ministerial direction. For newly registered reservoirs, the 12 month period starts when the undertaker is notified by the Environment Agency. For reservoirs under construction, an onsite flood plan is required before the preliminary certificate can be provided.
Onsite flood plans describe the type of reservoir and details about the actions the undertaker should take to control the situation. This enables a rapid response to manage any onsite incidents and related flood risks.
The plans contain:
- details of essential personnel
- clear actions the undertaker will take to prevent or control and mitigate an uncontrolled release of water
- reference to areas that are at risk from flooding off-site
The final point is important as the public living downstream of reservoirs may be unaware of the risk posed by reservoirs upstream. Having this information to hand enables the emergency services and local resilience forums to be quickly informed.
There are 2 elements of the onsite flood plan requirements. The first requires a qualified civil engineer to certify that the reservoir has an onsite flood plan prepared. The second is the testing direction. This directs the undertaker how frequently they need to test their plan. We monitored compliance with the Flood Plan (Reservoirs Emergency Planning) Direction 2021 against both submissions.
7.1 Action taken by the regulator ahead of the deadline
We took steps to ensure compliance with the ministerial direction and the act.
On 22 April 2021, we issued the direction to all large raised reservoir undertakers. The direction said that flood plans must be prepared and certified within 12 months from being notified of the requirement.
Enforcing this was a large piece of work for us. The risk of non-compliance was high.
We sent reminder emails to undertakers who had not submitted their certificates in July 2021, October 2021 and January 2022.
We issued a final warning letter to undertakers who had not sent certificates on 22 March 2022, one month before the deadline.
7.2 Action taken by the regulator after the deadline
On 23 April 2022 - the day after the deadline - 215 registered large raised reservoirs (approximately 10%) were still non-compliant. Engineers had 28 days after the deadline to submit certificates. We took no enforcement action until after the 28 days had passed.
We took a risk-based approach to enforcement. Our enforcement team began to issue Notices of Intent to Prosecute to non-compliant high-risk reservoirs at the start of June 2022. We sent the same letter to undertakers of non-compliant not high-risk reservoirs and reservoirs under construction at the end of July. These letters gave notice that enforcement proceedings would start within 28 days of the date on the letter. We asked undertakers to tell us about any mitigating circumstances for consideration. We issued 66 letters of intent to prosecute.
We allocated ongoing cases of non-compliance to Enforcement Officers who began individual investigations from June 2022.
We issued formal warning letters to undertakers who submitted certificates after the deadline. This letter made it clear that it was our opinion that they had committed an offence. However, we proposed no further action at this point. We reserved the option to take this matter back into consideration should they commit future offences under the Reservoirs Act. It was not considered appropriate or in the public interest in most cases to prosecute undertakers who complied after the deadline.
For any remaining non-compliant reservoirs after these steps had been taken, we issued an interview letter and questionnaire. The questionnaire contained a formal caution and questions that would:
- clarify ownership
- ask whether the plans were in draft
- explore why the certificates were not submitted by the deadline
By 31 December, all reservoirs were compliant.

7.4 Next steps
There is one case which we are taking forward to prosecution. This is because of an unacceptably late submission of their flood plans with poor mitigating circumstances
We will use lessons learned from this work to help with the Reservoir Safety Reform Programme.
The engineering community have raised concerns about a potential future bottleneck in workload. Onsite flood plans need testing and reviewing every 5 years. We will continue to provide advice and guidance to undertakers and engineers. We encourage early reviews where suitable.
8. Appendix 2: reservoir safety reform
Following the incident at Toddbrook reservoir in 2019, the Government commissioned Professor David Balmforth to review Reservoir Safety in England. The Part A and B reports were published in March 2020 and May 2021 respectively. In his (Part B) Independent Reservoir Safety Review Report, Professor Balmforth made 15 recommendations to improve the reservoir safety regime in England. On 20 July 2022, the then Secretary of State made a ministerial statement accepting all recommendations. We have appointed a programme manager and project team to lead the reform. Each recommendation contains sub-recommendations. This makes more than 40 recommendations. We are working with Defra to complete all of these.
Some recommendations can be achieved within the current legislation. We have already started working on these. Some recommendations will need changes to secondary legislation, or new secondary legislation. Others will need new primary legislation. The programme is working towards public consultation in 2023/24. After the consultation, the Government will work to develop legislative proposals, with a view to laying these before Parliament when Parliamentary time allows.
For recommendation 7, Defra commissioned the Institution of Civil Engineers (ICE) to write a report on the future supply of engineers. ICE published this in February 2023. The report contains 6 recommendations for actions to increase the capacity and number of engineers.
The reservoir reform programme will take several years. More information can be found in a policy paper published in April 2023. We are looking to engage with all stakeholders throughout the process. We welcome suggestions or comments. If you would like to be involved email reservoirs@environment-agency.gov.uk.
Table 11: recommendations we are taking forward
| Recommendation | Short description of recommendation | Leading body |
|---|---|---|
| 1 | Divide high-risk reservoirs into 3 hazard classes a) More frequent inspection to be required for high hazard b) Thresholds between classes to be determined by the regulator in consultation c) Government should review threshold for high-risk designation | Joint Defra/ Environment Agency |
| 2 | Strengthen regulation a) The regulator to raise awareness of duties and responsibilities b) The regulator to support owners in developing their capacity c) The regulator to charge for regulation (and incentivise good behaviours) d) The regulator to adjudicate disputes between engineers and owners | Environment Agency |
| 3 | Introduce Reservoir Safety Management Plans (RSMPs) reflecting hazard class a) Owners should prepare RSMPs reflecting hazard class b) RSMPs should be kept as prescribed form of record c) Supervising engineer to review and certify annually; d) Owners to ensure competent staff (certified for higher hazard class) e) The regulator to produce guidance | Joint Defra/ Environment Agency |

9. Appendix 3: reservoir data and statistics
9.1 Dam category
Although not legally required, a reservoir construction or inspecting engineer should assign a dam category to a large raised reservoir as best practice. The category the engineer assigns depends on potential consequences of a dam breach. The dam category assigned is based on ICE guidance for reservoir flood spillway design and takes a risk-based approach to reservoir design and inspections.
Table 12: distribution of dam category as of 31 December 2022
| Dam category | Number of LRRs | % of total number of LRRs |
|---|---|---|
| A | 868 | 41.0% |
| B | 369 | 17.4% |
| C | 476 | 22.5% |
| D | 206 | 9.7% |
| Not assigned | 67 | 3.2% |
| Not known | 131 | 6.2% |
| Total | 2117 | 100% |
In table 12 a:
- category A dam is where a breach could endanger lives in a community
- category B dam is where a breach could endanger lives not in a community or could result in extensive damage
- category C dam is where a breach would pose negligible risk to life and cause limited damage
- category D dam - special cases where no loss of life can be foreseen as a result of a breach and very limited additional flood damage would be caused
- ‘not assigned’ case is where in some cases, engineers have not assigned a dam category yet. The majority of these are non-impounding and service reservoirs.
Before July 2013 engineers did not need to submit to us copies of section 10 reports that did not contain safety measures. The ‘not known’ category refers to where dam categories may not be available for some reservoirs. This category also includes reservoirs under construction where the dam category is yet to be determined. This number is reducing as we receive new reports.

In Table 13:
- LRRs are reservoirs that are in operation, abandoned, and under construction
- under construction reservoirs - includes both new reservoirs and those being altered
- abandoned reservoirs – although empty, an abandoned reservoir is still capable of holding at least 25,000 cubic metres of water above natural ground level
- discontinued reservoirs – the discontinuance of a dam, requires an undertaker to reduce a reservoir’s capacity to a volume that is less than 25,000 cubic metres
- proposed reservoirs - are locations at which a large raised reservoir may be constructed in the future
- Environment Agency reservoirs - comprises those reservoirs that are in operation, abandoned, and under construction

| Number of LRRs with MIOS for which there is no target date, but which have been outstanding for at least 5 years | Not applicable | 5 | 5 | 1 | 3 | 0 | 2 | 0 | 0 | 0 |
Measures in the interests of safety (MIOS) are essential works identified by an inspecting engineer during part of a section 10 inspection. The undertaker is legally required to implement MIOS.
The figures above for MIOS do not necessarily represent non-compliance. They represent the total number of reservoirs that have safety measures identified. Not all these safety measures are outstanding beyond their target date. The figures will vary according to how often engineers are identifying works that need doing at reservoirs - we have no control over this. It is not necessarily a figure to be concerned about unless the work is not done in time.
10. Appendix 4: steps taken by the enforcement authority to ensure that undertakers observe and comply with the requirements of the act
The Environment Agency refers to sections of the act in appendix 2.
The notices listed refer to:
- section 8(1) ‘Powers of enforcement authority in event of non-compliance with requirements as to construction or enlargement of reservoirs’ – the offence is failure to appoint a construction engineer
- section 10(7)(a) ‘Periodical inspection of large raised reservoirs’ – the offence is failure to appoint an inspecting engineer
- section 10(7)(b) ‘Periodical inspection of large raised reservoirs’ – the offence is that the latest Section 10 report contains safety recommendations and a date by which these must be done and the work has not been done as required or by the date required
- section 12A ‘flood plans: large raised reservoirs’ – this offence is that an undertaker has not provided a 12AA(3) certificate and 12AA(4) direction which is a legal requirement
- section 12(4) ‘Supervision of large raised reservoirs’ – the offence is failure to appoint a supervising engineer
- section 16(4) ‘Emergency powers’ – this notice tells the undertaker what measures we are taking in exercising our emergency powers
