Porirua Wastewater Treatment Plant Bypass
When there's heavy rainfall, like after cyclone Gita yesterday, lots of water can end up in the wastewater network (instead of travelling through the stormwater network). This means our wastewater pump stations and treatment plants are not able to cope with the extra volume of wastewater.
On 20 February 2018, some water bypassed the Porirua treatment plant, only receiving partial treatment with UV light, before being discharged from a pipe at Rukutane Point in Titahi Bay. There were also overflows into the Porirua harbour and near Plimmerton.
We always recommend you do not swim in harbours and rivers following heavy rainfalls, for at least 48 hours.
Please note the following:
- Regional Public Health recommends no swimming in the affected area.
- Health Warning signs will be posted around Titahi Bay.
