Raw sewage can discharge from the Combined Sewer Overflow (CSO) at Cromer Beach. If you want to know when your surf spot is polluted in real time, sign up to SAS's Sewage Alert Service at www.sas.org.uk/sewage-alert-service/ and receive a free text when the CSO discharges raw sewage.
The Sewage Alert Service covers over 200 beaches around England and Wales. The CSO at Cromer is below the putting green. SAS are working with Anglian Water to ensure you know when there's a raw sewage spill at Cromer. Diffuse pollution can also impact the water quality at Cromer.
