The waters have previously been identified under the EC Bathing Water Directive (76/160/EEC). Their identification as Sensitive Areas under the EC Urban Waste Water Treatment Directive confirms that advanced treatment, such as ultraviolet disinfection, has been provided to discharges from local waste water treatment works in order to help the bathing waters achieve compliance with the Bathing Water Directive. Ultraviolet disinfection helps to reduce pathogens in waste water discharges.
The designations are being made under the Urban Waste Water Treatment (England and Wales) Regulations 1994 which brought into domestic legislation the requirements of the European Council Directive 91/271/EEC concerning urban waste water treatment. The Regulations set standards and deadlines for the treatment of sewage according to the population served by sewage treatment works, and the sensitivity of receiving waters.
The Regulations require that all significant discharges be treated to at least secondary standards, and require more stringent treatment for discharges affecting identified Sensitive Areas. Under the Regulations, Sensitive Areas are identified (amongst other reasons) where further treatment than secondary is necessary to fulfil other Council Directives. Discharges into the waters listed in the Annex have all benefited from more than secondary treatment in order to help the water achieve standards contained within the Bathing Water Directive.
