The safety of reservoirs is of paramount importance to the
British Dam Society and is a key driving force behind many
of the meetings, events and research undertaken by the society.
This part of the website contains links and information relating
to:
The Reservoirs Act 1975 provides the legal framework to ensure
the safety of UK reservoirs that hold at least 25,000 cu m of
water above natural ground level. Approximately 2,500 reservoirs
are covered by the Act: some 80% of these are formed by embankment
dams with the remainder being concrete or masonry dams or service
reservoirs. The Act is applicable in England, Wales and Scotland:
it does not apply to Northern Ireland, although some reservoir
owners and operators there comply with the spirit of the Act. The Act identifies four key persons
or organisations with distinct functions and responsibilities
as follows:
- Undertakers
The Undertakers are generally the owners or operators of
the reservoir, and have ultimate responsibility for the
safety of the reservoir.
- Enforcement Authorities
The Enforcement Authority is responsible for ensuring
that the Undertakers observe and comply with the requirements
of the Act.
Since 1 October 2004 the Environment Agency has been the Enforcement
Authority for England and Wales. Further information on the
Act and the Environment Agency’s responsibilities can
be found on www.environment-agency.gov.uk/reservoirsafety/
The Enforcement Authorities in Scotland are the Regional Councils.
- Qualified Civil Engineers (also referred to as
Panel Engineers)
Qualified civil engineers are experienced reservoir engineers
appointed to one of the panels under the Act by the Secretary
of State in consultation with the Institution of Civil Engineers.
They are responsible for the design and supervision of construction,
the supervision of measures in the interests of safety,
inspection of reservoirs and the ongoing supervision of
reservoirs. There are currently four panels of engineers:
- All Reservoirs Panel
- Non-impounding Reservoirs Panel
- Service Reservoirs Panel
- Supervising Engineers Panel
Further details of these panels and a list of currently appointed
panel engineers can be found on www2.defra.gov.uk/db/panel/default.asp
- Secretary of State
The Secretary of State is responsible for overseeing the
activities of the Enforcement Authorities, appointment of
qualified civil engineers and making statutory instruments
to prescribe regulations.
Current responsibility for the Act in England lies with
the Secretary of State for Environment, Food and Rural Affairs.
Since 1 July 1999, the Scottish Parliament and the National
Assembly for Wales have had the powers to make specific
regulations for Scotland and Wales respectively, but these
have not yet been used.

R&D relating to a wide range of aspects of dam safety and performance is undertaken by many different organisations within the UK each year. The purpose of this R&D is to ensure and maintain high standards of performance and dam and reservoir safety. Funding for this research comes from a variety of sources including UK Government Agencies, the European Commission, Water Utility Companies and other associated companies and organisations with an interest in dams and reservoirs.
Responsibility for reservoir safety R&D for England and Wales has recently transferred to the Environment Agency from DEFRA. The Environment Agency has established a Reservoir Safety Theme Group to manage this work; this approach being consistent with existing Theme Groups set up under the Flood and Coastal Erosion Risk Management R&D Programme. The Reservoir Safety Theme is managed by Ian Hope, of the Environment Agency, with a theme advisory group (The Reservoir Safety Advisory Group [RSAG]), drawing on expertise from government, industry and academia to assist in this process.
Whilst existing R&D projects are to continue under Agency management, the Agency has also commissioned a fresh review of reservoir safety R&D and perceived R&D needs. During 2008, this project will deliver a summary of the current position regarding reservoir safety R&D, both in the UK and Internationally, along with a recommended prioritised list for R&D work to be undertaken and opportunities / ideas for research funding.
Survey of R&D Initiatives: If you would like to contribute towards this review by offering comments on existing R&D initiatives, suggesting new R&D needs or offering innovative ideas for funding such research, please complete the attached survey form and return by email, fax or post (details are on the form). Whilst the deadline for receipt of original contributions was 31st October 2007, the team is happy to receive feedback at any time during the project.
Workshop – Review and Prioritisation of Future Research Projects and Initiatives
A 2 day workshop was held at the end of January 2008 to review and help prioritise proposed research initiatives. Participants included a number of panel engineers, owners, academics and other prominent members of the profession. The attendees were asked to ‘mark’ the projects on a scale of 1 to 10 (10 important) and level of difficulty from 1-3.

If you did not take part in the workshop, but would like to review and mark the proposed projects, we would welcome your contribution. Instructions are included with the voting forms, which may be accessed here. Completed sheets should be returned to Dr. Margaretta Ayoung by 20th March 2008.
Research Strategy: In order to prioritise R&D initiatives to provide maximum value to UK Reservoir Safety, it is necessary to have a clear framework or strategy within which the initiatives sit. A draft copy of the research strategy has now been produced. This presents the drivers affecting reservoir safety in the short and longer term and hence provides the basis for the subsequent identification and prioritisation of various initiatives. A draft copy of the research strategy may be viewed here. |
