Welsh Water has been fined £1.35m for failing to properly monitor water quality at 300 different sites.

The company pleaded guilty to 15 charges relating to more than 800 offences in 2020 and 2021.

It blamed the failures on a reorganisation and the implementation of a new system at the same time as the Covid pandemic.

District judge Gwyn Jones concluded the company had been negligent and had “no doubt caused significant embarrassment to all those dedicated personnel in Dwr Cymru”.
