The SuDS approach aims to manage surface water as close to source as possible using a wide range of techniques, including rainwater harvesting and infiltration where appropriate.
Nod y dull SuDS yw rheoli dŵr wyneb mor agos â phosibl at y ffynhonnell gan ddefnyddio amrywiaeth eang o dechnegau, gan gynnwys casglu dŵr glaw ac ymdreiddio lle bo hynny’n briodol.
