The Gold Coast City Council may need some extra toilet training, after raw sewerage was accidentally spilled twice in less than a week.

The first occurrence was near the popular Currumbin Creek last week, when a damaged mains-pipe spilled around 10,000 litres of effluent in the car park of the Currumbin RSL.

Swimming and fishing was banned in the nearby streams until the clean-up could be completed, it is understood a majority of the waste matter was kept out of storm drains.

Following that, up to a million litres of sewerage leaked into a canal at Hope Island earlier this week. The cause of the big dump has not been made public.

Council spokesperson Paul Gear said tests have been conducted, and the Council is waiting on the results to see if any damage has been done to overall water quality.

“Obviously the people that front the canal in Riverliegh Drive need to avoid the water but any further out from that it should be fine,” Mr Gear said.
