Urban Waste Water Treatment Regulations
Natural Resources Wales
'Urban waste water' is defined in the Urban Waster Water Treatment Regulations (UWWTR) as the mixture of domestic waste water from kitchens, bathrooms and toilets, the waste water from industries discharging to sewers, and rainwater run-off from roads and other impermeable surfaces such as roofs, pavements and roads draining to sewers. Urban waste water is often referred to as ‘sewage’. The UWWTR is intended to protect the water environment for the animals and plants that live in and around water, as well as for recreational purposes and use as a resource for drinking water, sanitation, industry and commerce. This entry refers to a series of spatial datasets that can used in Urban Waste Water management.
Under the UWWTR further sensitive areas have been identified because further treatment than secondary or equivalent treatment is necessary to meet other EC Directives such as the Water Framework Directive. Areas that come under as sensitive areas include Bathing Waters, Shellfish Waters and waters that are or soon to be Eutrophic.
UWWTR Shellfish Waters shows only areas that are designated by Welsh Government under the Water Framework Directive Regulations.
UWWTR Bathing Waters shows sites shows where treatment more stringent than secondary is necessary to fulfil the requirements of the Bathing Waters Directive and should be designated as sensitive areas by Defra
UWWTR Eutrophic Waters are water bodies that are (or may soon become) eutrophic should be designated as sensitive areas by Defra. This applies to still fresh waters, rivers, estuaries and coastal waters.
