This will have the aim of eliminating ecological harm from storm overflows in as soon as possible and making those improvements resilient to pressures such as climate change.
Nod hyn fydd dileu niwed ecolegol o ganlyniad i orlifoedd storm cyn gynted â phosibl a sicrhau bod y gwelliannau hynny’n gallu gwrthsefyll pwysau megis newid yn yr hinsawdd.
