Roedd Deddf Rheoli Llifogydd a Dŵr 2010 yn cynnwys darpariaethau i ddelio gyda dyledion drwg ac i annog tariffau cymdeithasol yn y diwydiant dŵr.  Dyma’r ddau argymhelliad a ddeilliodd o Adolygiad Walker, a ddaeth i ben ym mis Rhagfyr 2009.  Mae’r darpariaethau ar dariffau cymdeithasol yn galluogi ymgymeryddion dŵr a charthffosiaeth i gynnwys tariffau yn eu cynlluniau codi tâl, sydd wedi’u cynllunio i leihau’r taliadau ar gyfer grwpiau cwsmeriaid a fyddai fel arall wedi’i chael yn anodd i dalu biliau dŵr a charthffosiaeth yn llawn.  Rydym am weld opsiynau tariff sydd o fewn cyrraedd cwsmeriaid ac sy’n hawdd eu gweinyddu.  I helpu cwmnïau dŵr a charthffosiaeth i ddatblygu tariffiau priodol ar gyfer cwsmeriaid yng Nghymru, rydym wedi datblygu canllaw tariff cymdeithasol yr ydym yn ymgynghori arno ar hyn o bryd.  Daw’r ymgynghoriad i ben ar 6 Chwefror 2012 ac rwy’n croesawu unrhyw sylwadau.  Rydym yn bwriadu cwblhau’r canllawiau hyn ar ddechrau 2012.
The Flood and Water Management Act 2010 included provisions to deal with bad debt and encourage social tariffs in the water industry.  These were two recommendations that emerged from the Walker Review, which concluded in December 2009.  The provisions on social tariffs enable water and sewerage undertakers to include tariffs in their charging schemes that are designed to reduce the charges for groups of customers who would otherwise have difficulty in paying water and sewerage bills in full. We want to see tariff options that are accessible to customers and that are simple to administer. To help water and sewerage companies develop appropriate tariffs for customers in Wales we have developed social tariff guidance upon which we are currently consulting. The consultation ends on 6 February 2012 and I would welcome views.  We aim to finalise this guidance in early 2012.
