A minor leak has been discovered by contractors working on the construction of the new sewer pumping station at Corder Park.
At around 4:45 pm yesterday (21 April) the workers noticed the leak from the vicinity of the rising main which delivers wastewater to the Nelson North Treatment Plant.
The amount of the leak is very small with an estimated total of 30-40m3 being discharged in a 24hr period.
The District Health Board Public Health Service has been advised and the risk to public health has been assessed as low but signage warning against recreational activity has been erected along the Haven foreshore north of the city centre as a precautionary measure.
A permanent ban on shellfish gathering exists for the area. Signage will remain in place for at least two tidal cycles after the leak has been repaired.
Work began immediately to identify the location of the leak, and repairs will begin as soon as the that has been confirmed and tidal conditions allow.
