The incident happened after 12.4mm of rain fell within one hour, causing the area’s sewage pumping station to become overwhelmed and overflow onto the beach.
States lifeguards, stationed at the facility, are now advising the public not to use the pool for the next two days.
In a statement, the Government of Jersey said: ‘Environmental Health is advising the public not to use Havre des Pas swimming pool following an issue with the area’s pumping station after it reached capacity following a deluge of rainfall, resulting in sewerage entering the beach near to the pool.
‘The pumping station is now up and running but bathers are being advised to wait a couple of days until the pool has been refilled a number of times by the incoming tide.
‘The lifeguard service stationed at the pool is advising the public not to swim at this time and officers from Environmental Health have put up signage to notify the public about the incident.’
