Applying a Risk-based Approach and Improving the Evidence Base Related to Small Raised Reservoirs - FD2701

The report present a review of reservoir regulations that Defra introduced in 2013 and the provision for implementing new regulation for Small Raised Reservoirs, i.e., Water storage lakes/ponds that fall below the minimum size to be included within regulation standards.

The research had three main objectives:
1. To evaluate the impact of the changes implemented in the first phase of The Flood and Water Management Act 2010 reservoir provisions in relation to large raised reservoirs.
2. To provide evidence on the number of small raised reservoirs between 10,000m3 and 25,000m3 and crucially the level of risk SRRs pose in order to consider a decision on implementing Phase 2 of Reservoir Safety Regulations.
3. To review the existing risk methodology, including consideration of any refinements such as the consideration of probability and exemptions of certain reservoir types to provide information to make decisions on potential changes to regulation.
