Residents in Sandymount are calling for action after raw sewage was discharged onto the beach yesterday.
Locals say a "torrent" was released from the drain yesterday afternoon, including used condoms and sanitary products.
Concerns have been raised about public health, because the area is a popular spot for walkers and those with dogs.
Chairman of the local Resident's Association, David Turner, says this has to stop:
"We've reported this before to the Environmental Protection Agency and we've had the matter supposedly closed out by Irish Water."
"This is something the requires some re-engineer to introduce additional capacity," he said, to avoid the storm drain overflowing.
David has called for public health signage to be erected to warn walkers and dog walkers of the sewaage.
Response
Uisce Éireann and Dublin City Council are investigating reports of a stormwater overflow in the vicinity of St Albans Park.
A spokesperson says:
"This stormwater overflow is designed to protect Ailesbury Gardens and St Albans Park from flooding during periods of intense rainfall."
