English: Yes, thank you, Mike Hedges. As Mike Hedges will know, we've got a very good overflow scheme, which is a natural solution in his constituency, I think it is, at the top, which benefits my constituency. And that's a very good example of catchment area approaches, because obviously the river flows through a large number of different areas of Wales. It's very important therefore to make sure that we have sustainable nature-based solutions to divert, as he says, as much surface water as possible away from the sewerage systems in the first place to avoid the overflow that he speaks of. We've taken a number of steps to tackle discharges from overflows. This includes making sustainable drainage systems, or SuDS, mandatory on almost all new building developments. The purpose of this is to relieve pressure on the network by redirecting and slowing down the speed at which such surface water enters the sewage system and it will help ensure that our storm overflows are used only as a very last resort. As we speak, the water companies are preparing drainage and waste water management plans, which will be published for public consultation at the beginning of next year. The plans will provide a mechanism for water companies, local authorities and landowners to work together to develop a resilient and affordable waste water network to identify evidence-based priorities for investment. I have had a number of meetings with Dŵr Cymru Welsh Water. I understand that they have investigated high-spilling combined overflows in the River Tawe as part of their storm overflow assessment framework investigations. Natural Resources Wales is working with the water companies to ensure investment is targeted appropriately. They also ensure that using nature-based solutions, which will reduce discharges from overflows and deliver wider environmental and social benefits, are taken into account when planning the network.
Welsh: Ie, diolch, Mike Hedges. Fel y gŵyr Mike Hedges, mae gennym gynllun gorlifiant da iawn, sy'n ateb naturiol yn ei etholaeth ef, rwy'n credu, ar y pen uchaf, sydd o fudd i fy etholaeth innau. Ac mae honno'n enghraifft dda iawn o ddulliau dalgylch, gan fod yr afon, yn amlwg, yn llifo drwy nifer fawr o wahanol ardaloedd yng Nghymru. Mae'n bwysig iawn sicrhau felly fod gennym atebion cynaliadwy ar sail natur i ddargyfeirio, fel y dywed, cymaint o ddŵr wyneb â phosibl o'r systemau carthffosiaeth yn y lle cyntaf er mwyn osgoi'r gorlifo y mae'n sôn amdano. Rydym wedi rhoi nifer o gamau i fynd i'r afael â gollyngiadau o ganlyniad i orlifiant. Mae hyn yn cynnwys gwneud systemau draenio cynaliadwy, neu SuDS, yn orfodol ar bron i bob datblygiad adeiladu newydd. Diben hyn yw lleddfu pwysau ar y rhwydwaith drwy ddargyfeirio ac arafu pa mor gyflym y mae dŵr wyneb o'r fath yn mynd i mewn i'r system garthffosiaeth a bydd yn helpu i sicrhau bod ein systemau gorlifiant stormydd yn cael eu defnyddio fel dewis olaf yn unig. Wrth inni siarad, mae'r cwmnïau dŵr yn paratoi cynlluniau draenio a rheoli dŵr gwastraff, a fydd yn cael eu cyhoeddi ar gyfer ymgynghoriad cyhoeddus yn gynnar y flwyddyn nesaf. Bydd y cynlluniau'n darparu mecanwaith i gwmnïau dŵr, awdurdodau lleol a pherchnogion tir weithio gyda'i gilydd i ddatblygu rhwydwaith dŵr gwastraff gwydn a fforddiadwy i nodi blaenoriaethau ar sail tystiolaeth gyfer buddsoddi. Rwyf wedi cael nifer o gyfarfodydd gyda Dŵr Cymru. Deallaf eu bod wedi ymchwilio i orlifiant cyfunol sy'n gollwng yn sylweddol i Afon Tawe fel rhan o'u hymchwiliadau i'r fframwaith asesu gorlifiant stormydd. Mae Cyfoeth Naturiol Cymru yn gweithio gyda'r cwmnïau dŵr i sicrhau bod buddsoddiad yn cael ei dargedu'n briodol. Maent hefyd yn sicrhau bod atebion ar sail natur, a fydd yn lleihau gollyngiadau o ganlyniad i orlifiant ac yn sicrhau buddion amgylcheddol a chymdeithasol ehangach, yn cael eu hystyried wrth gynllunio'r rhwydwaith.
