Cullercoats Bay: Defective Pipes Behind Eight Years of Bacterial Water Pollution

What we know

Cullercoats Bay, a swimming beach in North Tyneside, north-east England, has been rated "poor" — the lowest possible grade — since 2018. The Environment Agency, the UK public body responsible for these assessments, measures the concentration of bacteria linked to human and animal faeces in bathing water.

For several years, Northumbrian Water, the Environment Agency, and North Tyneside Council failed to identify the source of contamination. Northumbrian Water attributed the poor rating to groundwater contamination without pinpointing the cause.

A breakthrough came through recent inspection and excavation work on Beverley Terrace: the water company discovered damaged private and public pipes, as well as poorly connected domestic pipes.

The likely cause identified

Northumbrian Water suspects these defective pipes leaked wastewater into the soil. The contaminated groundwater then infiltrated the bay, explaining the persistent water quality degradation since 2018.

Repairs underway

Northumbrian Water has repaired its own damaged pipes. Work is continuing in collaboration with property owners to fix the defective private pipes.

Richard Warneford, Northumbrian Water's sewerage operations director, said the company hopes these actions will have a positive effect on bathing water quality at Cullercoats.

The Environment Agency will conduct new water quality tests to verify whether the repairs have permanently resolved the problem.

Timeline

1. 2018
   Cullercoats Bay receives "poor" rating for bathing water quality — a classification maintained every year since.
2. 2022
   Northumbrian Water installs a drain at the bay, claiming investigations showed its own infrastructure was not the primary cause of pollution.
3. 2026 (recent)
   Excavation work on Beverley Terrace reveals damaged pipes and poorly connected pipes. Northumbrian Water repairs its public pipes and begins work with property owners on private pipes.
4. The Environment Agency will conduct new tests to confirm whether repairs have resolved the pollution problem.
