Local Authority Services and the Water Environment Advice Note on the Water Framework Directive for Local Authorities across the Midlands June 2012 How can this Advice Note help Local Authorities? The European Water Framework Directive, major surface water flooding events (such as the summer of 2007), recent droughts, the impacts of climate change, and future development needs are all driving the growing importance of managing the water environment. This Advice Note provides information to local authorities on the important contribution they can make to local improvements in the water environment and to meeting the objectives of the Water Framework Directive. It has been prepared by the Environment Agency and Sustainability West Midlands, working in partnership with local authorities from across the Midlands. We are particularly grateful for the assistance provided by Nottingham City Council, Worcestershire County Council and Wyre Forest District Council during the preparation of the document. The Advice Note addresses the following: • What is the European Water Framework Directive (WFD)? • Why is the water environment and the WFD important to local economies and communities? • What are the roles for local authorities under the Water Framework Directive? • How can local authorities contribute to WFD objectives? • What further advice, information and support is available to local authorities from the Environment Agency and others?

The Water Framework Directive (WFD) came into The Directive sets a target for all surface and effect in December 2000 and was enacted into groundwater water bodies to reach ‘good status’ by UK law in December 20031. It established a legal 2015. However, it recognises that some water bodies framework for the protection, improvement and are ‘artificial’ or ‘heavily modified’ because they have sustainable use of water bodies across Europe been created or modified to support uses such as and applies to all surface water bodies, including water supply, flood protection, navigation or urban rivers, streams, brooks, lakes, estuaries and canals, infrastructure, and sets lower targets accordingly. coastal waters out to one mile from low water, and ‘Artificial’ or ‘heavily modified’ water bodies need to groundwater bodies. It brings together and updates reach ‘good ecological potential’ by 2027. a raft of existing EU water legislation and sets challenging targets for the ecological quality for all water bodies2. Objectives of the WFD include: • to achieve ‘good’ status for all water bodies by 2015 (or later dates of 2021 or 2027 subject to criteria set out in the Directive); • preventing deterioration in the status of water bodies; • reducing pollution from priority polluting substances; • preventing and/or limiting pollution input into groundwater; • conserving aquatic ecosystems, habitats and species; • mitigating the effects of floods and droughts on water bodies; and • promoting sustainable use of water as a natural resource, and balancing abstraction and recharge. 1 Water Environment (Water Framework Directive) (England and Wales) Regulations 2003. 2 A Water Body means a discrete and significant element of surface water such as a lake, reservoir, stream, river or canal, part of a stream, river or canal, or a stretch of coastal water; or a distinct volume of groundwater within an aquifer.

The WFD sets the requirement that nothing Ecological status is measured on the scale of high, should be done to a water body which would cause good, moderate, poor and bad.

Local Authority Services and the Water Environment 3 Quality of water bodies in the Midlands Across the East and West Midlands over the past 20 years we have seen major improvements in water quality in our rivers, brooks and lakes. However, in 2009, only 22% of water bodies in the EA Midlands region met the WFD standards of having ‘good ecological status or potential’ (compared with 27% nationally) and 24% of watercourses were rated as ‘poor’ or ‘bad’ ecological status or potential – see map.
