During heavy rain over the weekend stormwater infiltrated the sewer system and caused overflows from the Hatea pumping station on Whareora Rd and Waverly Street pump station in Onerahi, as well as a number of manholes.

The city’s main wastewater treatment plant went into bypass mode.

The Northland Medical Officer of Health has advised that swimmers should stay out of the water in the upper harbour upstream of Onerahi for 5 days or until water tests show that it is safe to swim.  People involved in activities that are likely to involve head immersion such as kayaking and dingy sailing should follow the same advice as for swimmers. Shellfish should not be collected the upper harbour for 28 days. It is best not to eat fish caught in the upper harbour for 5 days.

People who have contact with sewage-contaminated water should thoroughly wash and dry their hands with soap and water afterwards.   Open cuts or sores should be kept clean and covered with waterproof sticking plasters.
