English: Managed realignment may also be the favoured option in areas of low public exposure to risk or where land values make it difficult to justify public expenditure on engineering works, such as the case in low lying undeveloped coastal areas.
Welsh: Mae'n bosibl mai ail-alinio rheoledig fydd yr opsiwn a ffefrir mewn ardaloedd lle mae cysylltiad y cyhoedd â'r risg yn isel neu le mae gwerth y tir yn ei gwneud hi'n anodd cyfiawnhau gwariant cyhoeddus ar waith peirianyddol, fel sy'n wir mewn ardaloedd arfordirol heb eu datblygu sydd ar dir isel.
English: Bearing these considerations in mind, proposed development in areas of coastal change should only take place where risks and consequences are understood and can be acceptably managed over the lifetime of the development.
Welsh: O gofio'r ystyriaethau hynny, ni ddylid caniatâu datblygiad mewn ardaloedd lle mae'r arfordir yn newid oni deellir y risgiau a'r canlyniadau ac y gellir eu rheoli'n dderbyniol dros oes y datblygiad.

Welsh: Strategaeth Genedlaethol ar gyfer rheoli perygl llifogydd ac erydu arfordirol, Llywodraeth Cymru 2011
English: The nature of new uses which may be suitable in areas subject to change should be carefully considered, including the impacts of, or opportunities afforded, by making incremental changes in an area.
Welsh: Dylid rhoi ystyriaeth ofalus i natur defnyddiau newydd a allai fod yn addas mewn ardaloedd sy'n destun newid, gan gynnwys effeithiau gwneud newidiadau graddol mewn ardal neu'r cyfleoedd y gallai hynny esgor arnynt.
English: Connections should also be made to strategies for the provision of green infrastructure and sustainable drainage schemes and to wider wellbeing plans to ensure social and economic resilience of settlements and their ability to adapt to change over the long term.
Welsh: Dylid creu cysylltiadau hefyd â strategaethau ar gyfer darparu seilwaith gwyrdd a chynlluniau draenio cynaliadwy yn ogystal â chynlluniau llesiant ehangach i sicrhau cydnerthedd cymdeithasol ac economaidd aneddiadau a'u gallu i ymaddasu i newid dros yr hirdymor.
English: Where active interventions are needed in areas which already contain development, a full understanding of the implications will need to be drawn up by the local authority in conjunction with all relevant stakeholders and roles and responsibilities in the process clearly identified.
Welsh: Lle bo angen ymyriadau gweithredol mewn ardaloedd sydd â datblygiad ynddynt eisoes, bydd angen i'r awdurdod lleol, ar y cyd â'r holl randdeiliaid perthnasol, ddangos bod yna ddealltwriaeth lawn o'r goblygiadau a rhaid nodi rolau a chyfrifoldebau pawb yn y broses.
English: Recognising the Environmental
Welsh: Adnabod Ansawdd
English: Qualities of Places
Welsh: Amgylcheddol Lleoedd
English: The water industry itself is a source of green jobs and water services support energy and food production, recreation and tourism and connect homes and businesses to the infrastructure networks upon which they depend.
Welsh: Mae'r diwydiant dŵr ei hun yn ffynhonnell swyddi gwyrdd ac mae gwasanaethau dŵr yn cefnogi prosesau cynhyrchu ynni a bwyd, hamdden a thwristiaeth, ac yn cysylltu cartrefi a busnesau â'r rhwydweithiau seilwaith maent yn dibynnu arnynt.
English: As well as this existing natural ecosystems play an important role in providing water quality and flood management.
Welsh: Yn ogystal, mae ecosystemau naturiol yn chwarae rhan bwysig i wella ansawdd dŵr a rheoli llifogydd.
English: Whilst legislation prohibits surface water discharge to foul sewers, additionally, surface water from new developments should not be discharged to combined systems because of the risk of pollution when combined systems overflow, and because they increase the volume of contaminated water requiring transporting and treating.
Welsh: Er bod deddfwriaeth yn gwahardd rhyddhau dŵr wyneb i garthffosydd budr, ni ddylai dŵr wyneb o ddatblygiadau newydd gael ei ryddhau i systemau cyfunol chwaith oherwydd y risg o lygredd pan fydd systemau cyfunol yn gorlifo, ac am eu bod yn cynyddu cyfaint y dŵr halogedig sydd angen ei gludo a'i drin.
English: This is a costly and energy intensive process and contrary to aims for the Welsh public sector to become carbon neutral by 2030.
Welsh: Mae hon yn broses ddrud sy'n gofyn am lawer o ynni ac felly'n groes i amcanion i sector cyhoeddus Cymru o fod yn garbon niwtral erbyn 2030.
English: Separate surface water sewers may be provided by a sewerage undertaker or local authority, for example highways drainage and Sustainable Drainage Systems (SuDS), and these discharge directly without treatment.
Welsh: Gall carthffosydd dŵr wyneb ar wahân gael eu darparu gan ymgymerwr carthion neu awdurdod lleol, er enghraifft, draeniad prif ffyrdd a Systemau Draenio Cynaliadwy, ac mae'r rhain yn arllwys yn uniongyrchol heb driniaeth.
English: Whatever drainage options are proposed for a development, provisions should be in place for future maintenance in the short and long term.
Welsh: Pa opsiynau draeniad bynnag a gyflwynir ar gyfer datblygiad, dylai darpariaethau fod ar waith ar gyfer cynnal a chadw yn y dyfodol, yn y tymor byr a'r hirdymor.
English: Development which is poorly designed or badly located can exacerbate problems associated with resource depletion, exposure to surface water flooding and diffuse pollution.
Welsh: Gall datblygiad sydd wedi'i ddylunio'n wael neu sydd mewn lleoliad gwael waethygu'r problemau sy'n gysylltiedig â gorddefnyddio adnoddau, cysylltiad â llifogydd dŵr wyneb a llygredd gwasgaredig.
English: protect and improve water resources by promoting and encouraging increased efficiency and demand management of water as part of new developments, particularly in those areas where water resources may be under pressure or may not be available;
Welsh: warchod a gwella adnoddau dŵr drwy hyrwyddo ac annog mwy o effeithlonrwydd a rheoli'r galw mewn perthynas â dŵr fel rhan o ddatblygiadau newydd, yn enwedig yn yr ardaloedd hynny lle gallai adnoddau dŵr fod o dan bwysau neu heb fod ar gael o bosibl;
English: ensure that the infrastructure on which communities and businesses depend is adequate to accommodate proposed development so as to minimise risk to human health and the environment and prevent pollution at source;
Welsh: sicrhau bod y seilwaith y mae cymunedau a busnesau'n dibynnu arno yn ddigonol i ymdopi â'r datblygiad arfaethedig er mwyn lleihau cymaint â phosibl y risg i iechyd pobl a'r amgylchedd ac atal llygredd yn ei darddiad;
English: ensure sustainable drainage systems are an integral part of design approaches for new development;
Welsh: sicrhau bod systemau draenio cynaliadwy yn rhan annatod o'r gwaith dylunio ar gyfer datblygiad newydd;
English: ensure the protection of the quantity and quality of surface and ground water supplies is taken into account as part of development proposals.
Welsh: sicrhau y rhoddir ystyriaeth i ddiogelu swm ac ansawdd y cyflenwadau dŵr wyneb a'r dŵr daear fel rhan o'r cynigion datblygu.
English: Embracing integrated approaches should make a contribution toward achieving the requirements imposed by EU Water Framework Directive

Welsh: Dylai gwarchod adnoddau dŵr fod yn seiliedig ar sicrhau defnydd cynaliadwy yn y dyfodol.
English: Meeting short term needs should be balanced against ability to protect water resources over the long term.
Welsh: Dylid cydbwyso anghenion tymor byr yn erbyn y gallu i warchod adnoddau dŵr yn yr hirdymor.
English: This may mean that the location of new development, and its type, requires careful consideration.
Welsh: Mae hyn yn olygu bod angen ystyried lleoliad datblygiad newydd a'r math o ddatblygiad yn ofalus.
English: Water intensive uses may not be appropriate in areas of water shortage and constraint.
Welsh: Mae'n bosibl nad yw defnyddiau sy'n defnyddio llawer o ddŵr yn briodol mewn ardaloedd lle mae prinder a chyfyngiadau dŵr.

Welsh: Nodyn Cyngor Technegol 12: Dylunio, Llywodraeth Cymru 2016
English: Capacity of Water Supply and Sewerage/
Welsh: Gallu'r Cyflenwad Dŵr a Seilwaith
English: The adequacy of water supply and sewerage infrastructure should be fully considered when proposing development, both as a water service and because of the consequential environmental and amenity impacts associated with a lack of capacity.
Welsh: Dylai digonolrwydd y cyflenwad dŵr a'r seilwaith carthffosiaeth gael ei ystyried y llawn wrth gynnig datblygiad, a hynny fel gwasanaeth dŵr ac oherwydd yr effeithiau y mae diffyg capasiti yn eu cael ar yr amgylchedd ac ar amwynderau.
English: Even where there is theoretical capacity, timely investment in infrastructure is required to ensure that new development does not adversely affect water supplies or sewerage drainage systems and have consequential impacts on water quality and surface water flooding.
Welsh: Hyd yn oed lle mae capasiti damcaniaethol, mae angen buddsoddiad amserol mewn seilwaith i sicrhau nad yw datblygiad newydd yn cael effaith andwyol ar gyflenwadau dŵr neu systemau draenio carthffosiaeth a chael effaith ganlyniadol ar ansawdd dŵr a llifogydd dŵr wyneb.
English: Planning authorities should, as far as possible, develop a strategic and long-term approach to infrastructure provision when preparing development plans.
Welsh: Dylai awdurdodau cynllunio, gymaint ag y medrant, ddatblygu ymagwedd strategol a hirdymor at ddarparu seilwaith wrth baratoi cynlluniau datblygu.
English: This means maximising the use of existing infrastructure and considering how the provision of different types of infrastructure can be co-ordinated.
Welsh: Mae hyn yn golygu gwneud y defnydd gorau posibl o seilwaith sy'n bodoli'n barod ac ystyried sut mae modd cydlynu'r modd y darperir y gwahanol fathau o seilwaith.
English: Planning authorities and infrastructure providers must work together closely to achieve the most sustainable outcome.
Welsh: Rhaid i awdurdodau cynllunio a darparwyr seilwaith weithio'n glos â'i gilydd i sicrhau'r canlyniadau mwyaf cynaliadwy.
English: Planning authorities should encourage the use of sites where existing water supply and/or sewerage and drainage provision problems can be solved and seek to avoid the use of sites where adequate provision is unlikely to be achieved.
Welsh: Dylai awdurdodau cynllunio annog y defnydd o safleoedd lle mae modd datrys problemau gyda'r cyflenwad dŵr a neu'r ddarpariaeth carthffosiaeth a draeniau cyfredol a cheisio osgoi defnyddio safleoedd lle mae darpariaeth ddigonol yn annhebygol o gael ei chyflawni.
English: A strategic approach with neighbouring authorities may be needed, particularly where strategic sites or new settlements are proposed.
Welsh: Efallai y bydd angen gweithio mewn ffordd strategol gydag awdurdod cyffiniol, yn enwedig lle cynigir safleoedd strategol neu aneddiadau newydd.
English: Development may need to be phased, in consultation with the relevant utilities providers, to allow time to ensure that the provision of utilities can be managed in a way consistent with sustainable development policies.
Welsh: Mae'n bosibl y bydd angen i'r datblygiad ddigwydd fesul cam, mewn ymgynghoriad â'r darparwyr cyfleustodau perthnasol, i ganiatáu amser i sicrhau bod modd rheoli'r gwaith o ddarparu cyfleustodau mewn ffordd sy'n gyson â pholisïau datblygu cynaliadwy.

Welsh: Ansawdd Dŵr a Llifogydd Dŵr Wyneb
English: Schedule 3 Flood and Water Management Act 2010
Welsh: Atodlen 3, Deddf Rheoli Dŵr a Llifogydd 2010
English: The relationship between the various types of drainage infrastructure is complex, for example, some highway drains carry surface water from public sewers and some highway infrastructure discharges into public sewers.
Welsh: Mae'r berthynas rhwng y gwahanol fathau o seilwaith draeniad yn gymhleth, er enghraifft, mae rhai draeniau priffordd yn cario dŵr wyneb o garthffosydd cyhoeddus ac mae peth seilwaith priffordd yn gollwng i garthffosydd cyhoeddus.
English: Understanding the role which the various types of infrastructure play is important in securing the best approach to avoid both flooding and diffuse pollution.
Welsh: Mae'n bwysig deall rôl gwahanol fathau o seilwaith wrth sicrhau'r dull gorau er mwyn osgoi llifogydd a llygredd gwasgaredig.
English: Effective collaboration between drainage, highway and planning authorities will be required.
Welsh: Bydd gofyn am gydweithio effeithiol rhwng awdurdodau draenio, priffyrdd a chynllunio.
English: Planning authorities should secure better management of drainage and surface water so as to tackle these issues by:
Welsh: Dylai awdurdodau cynllunio sicrhau rheolaeth well o ddraenio a dŵr wyneb er mwyn mynd i'r afael â'r materion hyn drwy:
English: ensuring sustainable drainage systems are incorporated into development enabling surface water to be managed close to or at source;
Welsh: sicrhau bod systemau draenio cynaliadwy yn cael eu hymgorffori mewn datblygiad fel bod modd rheoli dŵr wyneb yn ei darddiad neu gerllaw;
English: ensuring connection to the sewer in sewered areas and by minimising the proliferation of private sewage systems.
Welsh: galluogi cysylltiad â'r garthffos mewn ardaloedd â charthffosydd a thrwy leihau cynnydd yn nifer y systemau carthion preifat.
English: Sustainable Drainage Systems (SuDS) and Development
Welsh: Systemau Draenio Cynaliadwy (SuDS) a Datblygiad
English: Adoption and management arrangements, including a funding mechanism for maintenance of SuDS infrastructure and all drainage elements are to be agreed by the SAB as part of this approval.
Welsh: Bydd angen i'r SAB gytuno ar y trefniadau mabwysiadu a rheoli, gan gynnwys y fecanwaith ariannu ar gyfer cynnal a chadw seilwaith SuDS a holl elfennau'r draeniad, hynny fel rhan o'r gymeradwyaeth.
English: This will ensure that SuDS infrastructure is properly maintained and functions effectively for its design life.
Welsh: Bydd hynny'n sicrhau bod seilwaith SuDS yn cael ei gynnal a'i gadw'n briodol a'i fod yn gweithio'n effeithiol am ei oes.
English: In guiding new development the planning system should at the very least ensure the incorporation of measures at an individual site scale, particularly in urban areas, in order to secure cumulative benefits over a wider area.
Welsh: Wrth lywio datblygiad newydd, dylai'r system gynllunio sicrhau bod y mesurau'n cael eu hymgorffori o leiaf Safonau anstatudol a argymhellir ar gyfer draeniau cynliadwy ar raddfa safle unigol, yn enwedig mewn ardaloedd trefol, er mwyn sicrhau manteision cronnus dros ardal eang.
English: A concerted effort of this nature will bring benefits over a whole catchment.
Welsh: Daw ymdrech bendant fel hon â manteision dros y dalgylch cyfan.
English: At a development plan level, however, there will be considerable advantages associated with developing collaborative approaches which, drawing on evidence obtained through green infrastructure assessments, integrate SuDS as part of growth strategies for particular areas.
Welsh: Ond ar lefel cynllun datblygu, daw manteision sylweddol o ddatblygu dulliau cydweithio sydd, gan ddefnyddio tystiolaeth asesiadau o'r seilwaith gwyrdd, yn integreiddio SuDS fel rhan o strategaethau twf ar gyfer ardaloedd penodol.
English: Design for multiple benefits and green infrastructure should be secured wherever possible and as part of Green Infrastructure Assessments suitable approaches towards the provision of SuDS should be identified.
Welsh: Dylid creu dyluniad sy'n esgor ar fanteision lluosog a seilwaith gwyrdd bob tro os medrir ac fel rhan o'r Asesiad o'r Seilwaith Gwyrdd, dylid nodi ffyrdd addas ar gyfer darparu SuDS.
English: It may, in some circumstances, be necessary for 'hard' infrastructure solutions to be preferred because of practical or archaeological considerations, but taking into account the role of water services in contributing to the quality of place, nature based solutions should be the preference.
Welsh: Efallai y bydd angen o dan rai amgylchiadau ffafrio adeiladu seilwaith 'caled' oherwydd ystyriaethau ymarferol neu archeolegol ond o gofio rôl gwasanaethau dŵr o ran cyfrannu at ansawdd lle, dylid dewis atebion sy'n seiliedig ar natur os medrir.
English: Development in Sewered Areas
Welsh: Datblygu mewn Ardaloedd â Charthffosydd
English: To ensure consistency of design and facilitate long-term maintenance, sewers should be built to Welsh Government standards and adopted.
Welsh: Er mwyn bod yn gyson o ran dylunio ac i hwyluso'r gwaith cynnal a chadw yn y tymor hir, dylid adeiladu'r carthffosydd i safonau Llywodraeth Cymru a'u mabwysiadu.
English: Lack of capacity or plans to improve capacity in the sewer is not a valid reason for a sewerage undertaker to refuse connection under Section 106 of the Water Industry Act 1991 and Natural Resources Wales may refuse to issue an environmental permit for private treatment in such circumstances.
Welsh: Nid yw diffyg capasiti neu ddiffyg gynllun i wella capasiti'r garthffos yn rheswm dilys i ymgymerwr carthffosydd wrthod cysylltu o dan Adran 106 Deddf Diwydiant Dŵr 1991 a gall Cyfoeth Naturiol Cymru wrthod rhoi trwydded amgylcheddol ar gyfer triniaeth breifat o dan yr amgylchiadau hynny.
English: Developers need an adoption agreement in place before construction commences and should consult sewerage undertakers in the early stages of design and planning.
Welsh: Mae angen i ddatblygwyr fod â chytundeb mabwysiadu yn barod cyn i'r gwaith adeiladu ddechrau a dylent ymgynghori ag ymgymerwyr carthffosiaeth yng nghamau cynnar y gwaith dylunio a chynllunio.
English: Development proposing the use of non-mains drainage schemes will only be considered acceptable where connection to the main sewer is not feasible
Welsh: Dim ond pan nad yw'n ymarferol cysylltu â'r brif garthffos y caiff datblygiad sy'n cynnig defnyddio cynlluniau draenio nad ydynt yn cysylltu â'r brif system ei ystyried
English: The installation of private sewage treatment facilities within publicly sewered areas is not considered acceptable because of the greater risk of failures leading to pollution when compared to public sewers.
Welsh: Nid yw gosod cyfleusterau trin carthion preifat mewn ardaloedd â charthffosydd cyhoeddus yn dderbyniol gan fod mwy o berygl i ddiffygion sy'n arwain at lygredd ddigwydd yn y rheini o'u cymharu â charthffosydd cyhoeddus.
English: Where non-mains sewage proposals, such as septic tanks and or independent sewage treatment systems, are included in development applications they should be subject to an assessment of their effects on the environment, amenity and public health in the locality, in accordance with the criteria set out in Circular 10/99, prior to the determination of the planning application.
Welsh: Pan geir cynigion carthion nad ydynt yn cysylltu â'r brif garthffos, fel tanciau septig a/ neu systemau trin carthion annibynnol, yn cael eu cynnwys mewn ceisiadau datblygu, dylent fod yn destun asesiad o'u heffeithiau ar yr amgylchedd, ar amwynderau ac ar iechyd y cyhoedd yn yr ardal leol, yn unol â'r meini prawf a nodir yng Nghylchlythyr 10/99, cyn penderfynu ar y cais cynllunio.

Welsh: Gofynion cynllunio mewn perthynas â defnyddio systemau carthffosiaeth preifat mewn datblygiadau newydd, gan gynnwys tanciau carthion a gweithfeydd bach trin carthion
English: Flooding as a hazard involves the consideration of the potential consequences of flooding, as well as the likelihood of an event occurring.
Welsh: Mae llifogydd fel perygl yn golygu ystyried canlyniadau posibl llifogydd, yn ogystal â'r tebygolrwydd y bydd llifogydd yn digwydd.
English: Planning authorities should adopt a precautionary approach of positive avoidance of development in areas of flooding from the sea or from rivers.
Welsh: Dylai awdurdodau cynllunio fabwysiadu dull rhagofalus o fynd ati'n gadarnhaol i osgoi datblygu mewn ardaloedd o lifogydd o'r môr neu o afonydd.
English: Surface water flooding will affect choice of location and the layout and design of schemes and these factors should be considered at an early stage in formulating development proposals.
Welsh: Bydd llifogydd o ddŵr wyneb yn effeithio ar ddewis lleoliad, diwyg a dyluniad cynllun, a dylid ystyried y ffactorau yn fuan yn y broses o lunio cynigion datblygu.
English: Government resources for flood and coastal defences are directed at protecting existing developments and are not available to provide defences in anticipation of future development.
Welsh: Caiff adnoddau'r llywodraeth ar gyfer amddiffynfeydd llifogydd ac arfordirol eu neilltuo ar gyfer amddiffyn datblygiadau sy'n bodoli'n barod ac nid ydynt ar gael i ddarparu amddiffynfeydd ar gyfer datblygiadau posibl y dyfodol.
English: Account should be taken of shoreline management plans and measures such as managed realignment, the creation of washlands and flood plain restoration as alternatives to engineered flood defences.
Welsh: Dylid ystyried cynlluniau rheoli traethlin a mesurau fel encilio rheoledig, creu golchdiroedd ac adfer gorlifdiroedd fel dulliau i'w defnyddio yn lle amddiffynfeydd llifogydd peirianyddol.
English: Together with flood consequences assessments they should assist understanding of how natural and man-made defences work as integral components of places and provide a means by which the cumulative effects of development can begin to be understood.
Welsh: Gyda'r asesiadau o ganlyniadau llifogydd, dylent ein helpu i ddeall sut mae amddiffynfeydd naturiol ac o waith dyn yn gweithio fel cydrannau annatod lleoedd a darparu modd o ddechrau deall effeithiau cynyddol datblygu.

Welsh: Nodyn Cyngor Technegol 15, Datblygu a Pherygl o Lifogydd, Llywodraeth Cynulliad Cymru 2004
English: The priority should be to protect the undeveloped or unobstructed floodplain from development and to prevent the cumulative effects of incremental development.
Welsh: Y flaenoriaeth yw diogelu'r gorlifdir sydd heb ei ddatblygu ac sy'n ddirwystr rhag ei ddatblygu a rhwystro effeithiau cynyddol datblygu cam wrth gam.
English: Such infrastructure should be designed and constructed so as to remain operational even at times of flood, to result in no net loss of floodplain storage, to not impede water flows and to not increase flood risk elsewhere.
Welsh: Dylid dylunio ac adeiladu seilwaith o'r fath fel ei fod yn parhau i weithredu hyd yn oed adeg llifogydd ac nad oes unrhyw golled net o le storio ar orlifdiroedd, nad yw'n rhwystro llif dŵr ac nad yw'n cynyddu'r perygl o lifogydd yn rhywle arall.
English: TAN 15: Development and Flood Risk should be referred to for further policy advice on development and flood risk.
Welsh: TAN 15 Datblygu a Pherygl o Lifogydd am gyngor polisi pellach ar ddatblygiad a pherygl llifogydd.
English: It will be important to note that developments located within flood risk areas remain at risk from flooding even if mitigation measures are applied.
Welsh: Bydd yn bwysig nodi bod datblygiadau mewn ardaloedd perygl llifogydd yn dal i fod mewn perygl o lifogydd hyd yn oed os defnyddir mesurau lleddfu.
