The designation aims to protect the water and prevent any deterioration in quality that could increase the required treatment of water to meet Drinking Water Standards. Drinking Water Protected Areas need to be identified under the Water Environment (Water Framework Directive) (England and Wales) Regulations 2017. This data shows the designated Drinking Water Protected Areas in Wales and is split into two separate layers for Surface Water Drinking Water Protected Areas and one for Groundwater Drinking Water Protected Areas. This aims to protect from over-abstraction and prevent deterioration in water quality that could increase the treatment of drinking water. Within these Drinking Water Protected Areas, we work with water companies to identify raw water sources that are 'at risk' of deterioration, which would result in the need for additional treatment.

Ardaloedd Gwarchodedig Dŵr Yfed. Nod y dynodiad yw gwarchod y dŵr ac atal unrhyw ddirywiad yn yr ansawdd, a allai gynyddu'r driniaeth sydd ei hangen ar y dŵr i fodloni’r Safonau Dŵr Yfed. Mae angen nodi Ardaloedd Gwarchodedig Dŵr Yfed o dan Reoliadau’r Amgylchedd Dŵr (Cyfarwyddeb Fframwaith Dŵr) (Cymru a Lloegr) 2017. Mae'r data hwn yn dangos yr Ardaloedd Gwarchodedig Dŵr Yfed dynodedig yng Nghymru ac mae wedi'i rannu'n ddwy haen ar wahân ar gyfer Ardaloedd Gwarchodedig Dŵr Yfed - Dŵr Wyneb ac un ar gyfer Ardaloedd Gwarchodedig Dŵr Yfed - Dŵr Daear. Nod hyn yw amddiffyn rhag gordynnu dŵr ac atal dirywiad mewn ansawdd dŵr a allai gynyddu triniaeth dŵr yfed. O fewn yr Ardaloedd Gwarchodedig Dŵr Yfed hyn, rydym yn gweithio gyda chwmnïau dŵr i nodi ffynonellau dŵr crai sydd 'mewn perygl' o ddirywio, a fyddai'n arwain at yr angen am driniaeth ychwanegol.
