Independent Reservoir Safety Review Report

An independent review of reservoir safety legislation and its application was commissioned by the Secretary of State for Environment, Food and Rural Affairs in 2020 and was led by Professor David Balmforth.

The review report, published on 13 May 2021, provides a comprehensive assessment of the current safety regime in England. It makes recommendations for improving the safety regime and to strengthen the roles and responsibilities for the regulator, reservoir owners and engineers.

Update on the Toddbrook Part A review recommendations from the EA

We have a message from Tony Deakin, Head of Reservoir Safety, Environment Agency which provides an update on the work arising from Part A of the Toddbrook review. Tony’s message is reproduced below.

“You may recall the actions as a result of Part A of the independent review into the 2019 Toddbrook Reservoir spillway failure by Prof David Balmforth.

At that time I set out a plan to respond to the Part A recommendations as follows:

  • Deliverable 1 – Spillway Design Guide
  • Deliverable 2 – Spillway Inspection Guide
  • Deliverable 3 – Spillway Failure Mechanisms Research
  • Deliverable 4 – Guidance on the contents of a well-structured package of information on the reservoir
  • Deliverable 5 – Guidance to Inspecting Engineers
  • Deliverable 6 - Guidance to Supervising Engineers
  • Deliverable 7 – Guidance to Owners

The team which supporting me to deliver this plan:

Kieron Kenny – kieron.kenny@turntown.co.uk

Viktor Pavlov – pavlovvv@binnies.com

Eddie Robinson – robinsoned@binnies.com

Tim Daly – tim.daly@mottmac.com

Many of you have already responded to my initial request and have generously offered your support to develop this guidance, for which I am grateful.  If you did respond and haven’t already been contacted by my team, then you should expect to be contacted in the next few weeks.  If you haven’t responded and would like to be involved, please get in touch with me or one of my team.  It’s important that this guidance is developed collaboratively by a representative cross section of the reservoir community and your support is necessary to achieve this.

Part B of the independent review will consider the legislative and regulatory framework which governs the management of reservoirs in England.  In anticipation of potential changes to legislation as a result of this review, we have adapted our plan and now intend to publish deliverables 4, 5, 6 and 7 as interim guidance, which will respond specifically to the recommendations of the Part A review, pending the future introduction of new or updated legislation.

My team has been busy developing the necessary plans to prepare and publish this guidance in the late summer/early autumn of this year and look forward to engaging with those of you who so generously offer your time.“

EA and NRW reservoir safety guidance relating to the pandemic

NRW has updated its guidance regarding compliance during Covid-19 restrictions and can be found here. The EA’s advice, published in April, remains valid and can be found here.

 

NRW also advise that with the increased use of social media to showcase work there is an increased risk that photos, diagrams and other information may reveal sensitive detail and expose vulnerabilities. Even small pieces of information, when pieced together over time can be harmful if accessed by anyone with a malicious intent. Before posting material about reservoir construction or maintenance, you are advised to seek the approval of the reservoir undertaker.

BDS Seminar

In lieu of the 2020 conference we are planning a virtual seminar this September using some of the material which would have been used at our conference. We are aware that many of our members will find it difficult to secure funding this year to (virtually) attend a one-day event and we wish to make access to the content as easy as possible. We therefore plan to present the seminar through four one-hour sessions. The sessions will be available on each Monday lunchtime through September, i.e. the 7, 14, 21 and 28 September. These will be free live events using pre-recorded presentations followed by live Q&A.
