Following correspondence from a number of constituents regarding spill reports around West Shore, Llandudno, further information has been provided to clarify the situation.
It has been explained that the vast majority of the recorded discharges are not linked to sewage entering the local coastline. Instead, they relate to surface water flows from the culverted River Creuddyn via Afon Creuddyn Surface Water Pumping Station. This water is discharged through the same offshore outfall used by the storm overflow system, located approximately 5 kilometres out to sea rather than on the coastline itself. This water is from a culvert that was installed around 100 years ago to prevent Llandudno from flooding and is not connected to the sewer network.
Furthermore, Dŵr Cymru Welsh Water has confirmed work has been done to find a way of recording legitimate storm overflow spills without including the surface water from Afon Creuddyn. Individual monitors on each section of pipe leading to the storm overflow means they now only record genuine storm overflow spills and not surface water from the Culvert.
Janet Finch-Saunders, Senedd Member for Bangor Conwy Môn said:
“A number of constituents have contacted me with understandable concerns about possible sewage spills at West Shore Beach, Llandudno.
Having sought further clarification, I understand that the vast majority of these recorded discharges relate to surface water flows from the culverted River Creuddyn via Afon Creuddyn Surface Water Pumping Station rather than sewage being released onto our coastline. The system was originally constructed to help protect Llandudno from flooding and operates separately from the sewer network.
While residents will rightly continue to expect transparency and high environmental standards, I felt it was important to share this information so that people have a clear understanding of what is being recorded and why.
Yn dilyn gohebiaeth gan nifer o etholwyr ynglŷn ag adroddiadau o ollyngiadau o amgylch Traeth Pen Morfa, Llandudno, darparwyd rhagor o wybodaeth i egluro'r sefyllfa.
Esboniwyd nad yw'r mwyafrif helaeth o'r gollyngiadau a gofnodwyd yn gysylltiedig â charthffosiaeth sy'n mynd i mewn i'r arfordir lleol. Yn hytrach, maen nhw’n ymwneud â llif dŵr wyneb o Afon Creuddyn trwy Orsaf Bwmpio Dŵr Wyneb Afon Creuddyn. Mae'r dŵr hwn yn cael ei ollwng trwy'r un ollyngfa ar y môr a ddefnyddir gan y system gorlif storm, sydd wedi'i leoli tua 5 cilometr allan i'r môr yn hytrach nag ar yr arfordir ei hun. Daw'r dŵr hwn o gwlfert a osodwyd tua 100 mlynedd yn ôl i warchod Llandudno rhag llifogydd ac nid yw wedi'i gysylltu â'r rhwydwaith carthffosiaeth.
Ar ben hynny, mae Dŵr Cymru wedi cadarnhau bod gwaith wedi'i wneud i ddod o hyd i ffordd o gofnodi gorlifoedd storm dilys heb gynnwys y dŵr wyneb o Afon Creuddyn. Mae monitorau unigol ar bob rhan o'r bibell sy'n arwain at y gorlif storm yn golygu eu bod bellach ond yn cofnodi gollyngiadau gorlif storm gwirioneddol, ac nid dŵr wyneb o'r cwlfert.
Meddai Janet Finch-Saunders, AS Bangor Conwy Môn:
"Mae nifer o etholwyr wedi cysylltu â mi gyda phryderon dealladwy am ollyngiadau carthffosiaeth posibl ar Draeth Pen Morfa, Llandudno.
Ar ôl ceisio cael eglurhad pellach, deallaf fod y mwyafrif helaeth o'r gollyngiadau hyn a gofnodwyd yn ymwneud â llif dŵr wyneb o Afon Creuddyn trwy Orsaf Bwmpio Dŵr Wyneb Afon Creuddyn yn hytrach na charthffosiaeth yn cael ei ryddhau i'n harfordir. Adeiladwyd y system yn wreiddiol i helpu i amddiffyn Llandudno rhag llifogydd ac mae'n gweithredu ar wahân i'r rhwydwaith carthffosiaeth.
Er y bydd trigolion yn disgwyl tryloywder a safonau amgylcheddol uchel o hyd, roeddwn i'n teimlo ei bod yn bwysig rhannu'r wybodaeth hon fel bod pobl yn cael dealltwriaeth glir o'r hyn sy'n cael ei gofnodi a pham.
