  21. Informatives The planning permission hereby granted does not extend any rights to carry out any works to the public sewerage or water supply systems without first having obtained the necessary permissions required by the Water Industries Act 1991. The applicant will either need to complete a Declaration of Works or submit an application for Build Over Sewer (BOS) Agreement to Dwr Cymru Welsh Water. Further information can be obtained via the Developer Services webpage at https://developers.dwrcymru.com/en/applications/planning/build-overor-near-to-sewers The applicant is also advised that some public sewers and lateral drains may not be recorded on our maps of public sewers because they were originally privately owned and were transferred into public ownership by nature of the Water Industry (Schemes for Adoption of Private Sewers) Regulations 2011. The presence of such assets may affect the proposal. In order to assist us in dealing with the proposal, the applicant may contact Dwr Cymru Welsh Water to establish the location and status of the apparatus. Under the Water Industry Act 1991 Dwr Cymru Welsh Water has rights of access to its apparatus at all times. As of 7th January 2019, this proposed development may be subject to Schedule 3 of the Flood and Water Management Act 2010. The development may therefore require approval of Sustainable Drainage Systems (SuDS) features, from the determining SuDS Approval Body (SAB), in accordance with the 'Statutory standards for sustainable drainage systems – designing, constructing, operating and maintaining surface water drainage systems'.
  22. Gwybodaeth Nid yw'r caniatâd cynllunio a roddir drwy hyn yn ymestyn unrhyw hawliau i wneud unrhyw waith i'r systemau carthffosiaeth gyhoeddus neu gyflenwi d"{r heb gael y caniatâd angenrheidiol yn gyntaf sy'n ofynnol gan Ddeddf Diwydiannau D"{r 1991. Bydd angen i'r ymgeisydd naill ai gwblhau Datganiad o Waith neu gyflwyno cais am Gytundeb Adeiladu Dros Garthffos (CATG) i D"{r Cymru. Mae rhagor o wybodaeth ar gael drwy dudalen we Gwasanaethau Datblygwyr yn https://developers.dwrcymru.com/en/applications/planning/build-over-near-to-sewers Cynghorir yr ymgeisydd hefyd nad yw rhai carthffosydd cyhoeddus a draeniau ochrol o bosibl wedi'u cofnodi ar ein mapiau o garthffosydd cyhoeddus oherwydd eu bod yn wreiddiol yn eiddo preifat ac wedi'u trosglwyddo i berchnogaeth gyhoeddus oherwydd natur Rheoliadau'r Diwydiant D"{r (Cynlluniau ar gyfer Mabwysiadu Carthffosydd Preifat) 2011. Gall presenoldeb asedau o'r fath effeithio ar y cynnig. Er mwyn ein cynorthwyo i ddelio â'r cynnig, gall yr ymgeisydd gysylltu â D"{r Cymru i sefydlu lleoliad a statws y cyfarpar. O dan Ddeddf y Diwydiant D"{r 1991 mae gan D"{r Cymru hawliau mynediad i'w gyfarpar bob amser. O 7 Ionawr 2019 ymlaen, gall y datblygiad arfaethedig hwn fod yn ddarostyngedig i Atodlen 3 o Ddeddf Rheoli Llifogydd a D"{r 2010. Felly, efallai y bydd angen cymeradwyaeth ar gyfer nodweddion Systemau Draenio Cynaliadwy (a adwaenir fel SuDS) ar gyfer y datblygiad, gan y Corff Cymeradwyo SuDS (a adwaenir fel SAB) sy'n penderfynu, yn unol â'r 'Safonau statudol ar gyfer systemau draenio cynaliadwy – dylunio, adeiladu, gweithredu a chynnal a chadw systemau draenio d"{r wyneb'.
