How does the Welsh Government measure sewage levels in rivers?

River water quality monitoring, which includes monitoring sewage discharges, is undertaken by Natural Resources Wales. NRW publishes annual environmental performance reports for both companies operating in Wales. Further information on NRW’s role in monitoring and enforcement can be found at the following link Natural Resources Wales / Storm Overflows.
