We have reviewed and refreshed our emergency response and resilience arrangements and tested them with our key partners as part of the national event, Exercise Watermark.
Rydym wedi adolygu a diweddaru ein trefniadau ar gyfer ymateb mewn argyfwng a chydnerthu ac wedi rhoi prawf arnynt gyda’n partneriaid allweddol fel rhan o’r digwyddiad cenedlaethol, Ymarfer Watermark.
