Urban Waste Water Treatment Regulations (UWWTR) Sensitive Area - Shellfish Waters
Rheoliadau Trin Dŵr Gwastraff Trefol

  • English

  • All

The Water Environment (Water Framework Directive) (England and Wales) Regulations 2017 (WFD Regulations 2017) requires specification of protected areas for those areas designated as nutrient sensitive areas.


UWWTR Sensitive Areas Shellfish Waters layer has been renamed from the UWWTD Sensitive Areas Shellfish Waters and updated to only show areas which are designated as Shellfish Waters under the WFD Regulations following Welsh Government review.


This is a spatial dataset showing the extent of the Urban Wastewater Treatment Directive (UWWTD) sensitive areas (Shellfish Water) in Wales.


The Urban Waste Water Treatment Directive (UWWTD) (91/271/EEC) is designed to reduce the pollution of freshwater, estuarine and coastal waters by domestic sewage and industrial wastewater collectively known as urban waste water. These water have been identified as a sensitive because further treatment than secondary or equivalent treatment is necessary to meet other EC Directives such as the Water Framework Directive.

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.
