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.

Diffinnir 'dŵr gwastraff trefol' yn y Rheoliadau Trin Dŵr Gwastraff Trefol (RhTDGT) fel y cymysgedd o ddŵr gwastraff domestig o geginau, ystafelloedd ymolchi a thoiledau, y dŵr gwastraff o ddiwydiannau sy'n gollwng i garthffosydd, a dŵr glaw ffo o ffyrdd ac arwynebau anhydraidd eraill fel toeau, palmentydd a ffyrdd sy'n draenio i garthffosydd. Cyfeirir at ddŵr gwastraff trefol yn aml fel 'carthion'. Bwriad y RhTGDT yw diogelu'r amgylchedd dŵr ar gyfer yr anifeiliaid a'r planhigion sy'n byw mewn dŵr ac o'i gwmpas, yn ogystal ag at ddibenion hamdden a'r defnydd ohono fel adnodd ar gyfer dŵr yfed, glanweithdra, diwydiant a masnach. Mae'r cofnod hwn yn cyfeirio at gyfres o setiau data gofodol y gellir eu defnyddio ym maes rheoli Dŵr Gwastraff Trefol. O dan y RhTGDT, mae ardaloedd sensitif pellach wedi'u nodi oherwydd bod angen triniaeth bellach na thriniaeth eilaidd neu gyfatebol i fodloni Cyfarwyddebau EC eraill megis y Gyfarwyddeb Fframwaith Dŵr. Mae'r ardaloedd sy'n dod o dan ardaloedd sensitif yn cynnwys Dyfroedd Ymdrochi, Dyfroedd Pysgod Cregyn a dyfroedd sydd eisoes yn Ewtroffig neu a fydd yn Ewtroffig cyn bo hir. Dim ond ardaloedd sydd wedi'u dynodi gan Lywodraeth Cymru o dan Reoliadau'r Gyfarwyddeb Fframwaith Dŵr y mae Dyfroedd Pysgod Cregyn RhTGDT yn eu dangos. Mae Dyfroedd Ymdrochi RhTGDT yn dangos safleoedd lle mae triniaeth fwy caeth na thriniaeth eilaidd yn angenrheidiol i fodloni gofynion y Gyfarwyddeb Dyfroedd Ymdrochi a dylai Defra eu dynodi'n ardaloedd sensitif Mae Dyfroedd Ewtroffig RhTGDT yn gyrff dŵr sydd (neu a allai’n fuan droi) yn ewtroffig a dylent gael eu dynodi'n ardaloedd sensitif gan Defra. Mae hyn yn berthnasol i ddyfroedd croyw llonydd, afonydd, aberoedd a dyfroedd arfordirol.
