Emergency services are responding to a fire at the Christchurch Wastewater Treatment Plant.
The fire is believed to have started on the roof on the No2 Trickling Filter before jumping across to the roof of the No1 Trickling Filter.
There were contractors working on the roof when the fire broke out. No one was injured and the site is being evacuated.
The roofs on both the trickling filters have collapsed.
Fire and Emergency New Zealand are on the scene with seven appliances, working to put out the blaze.
If you live or work in the area, please close your windows and doors.
Please stay away from the area and allow Fire and Emergency New Zealand's crews to work quick and safely to extinguish the fire.
The Christchurch Wastewater Treatment Plant is continuing to operate in a limited capacity.
Canterbury DHB’s Community and Public Health unit has issued a public health warning for smoke from the fire at the wastewater treatment plant in Bromley, Christchurch.
Air around this location is smoky and there is potential that people who are sensitive to smoke – such as those with heart or lung conditions, pregnant women, young children and the elderly – may experience symptoms including coughing, shortness of breath or eye, nose and throat irritation.
Canterbury Medical Officer of Health Dr Cheryl Brunton says exposure to smoke can worsen pre-existing health conditions such as asthma and heart disease.
“People affected by the smoke should close windows and doors and stay indoors.''
The easterly wind is sending smoke in the direction of some of Christchurch’s eastern suburbs and central city areas.
“Anyone experiencing health issues from the fire should contact their general practice team for advice, in the first instance,” Dr Brunton says.
What to do when it’s smoky outside
If you see or smell smoke outside, you should stay inside if it’s safe to do so.
