Summary

'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.

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.

This entry refers to a series of spatial datasets that can used in Urban Waste Water management. In 2023 the dataset was updated and renamed from the Urban Waste Water Treatment Directive (UWWTD). Please see the child metadata entries for more information on these updates.
