The blocked drains were reported early in the week. The Locality Steward has investigated but Welsh Water cannot help as there is no mains drainage. Balfour Beatty cannot clear the drains as it is contaminated water.
It appears foul water is discharging into a storm drain, contaminating the drainage system.
The Locality Steward is likely to call in the Environment Agency to investigate.
More information will be given when available.
