Extreme weather  |  27 Jul 2022

Check here for the latest information on how the wet weather is affecting our district.

Last update

With the sun now shining and the water starting to drain away in most places, we are going to stop updating this blog.  

There are still a few roads around the district that are still closed either due to slips or flooding. We are working to get these open as soon as possible.

We will update the status of key roads on our Facebook page.

People warned to stay away from beaches, rivers and floodwaters

Te Mana Ora (Community and Public Health) is warning people to avoid contact with beaches, rivers and floodwaters for two days. 

Dr Matthew Reid, Canterbury Medical Officer of Health, says the recent heavy rain has resulted in added pressure on sewerage systems, and overflows into many waterways.

“Flood waters may have been contaminated with sewage and the most important thing to remember when cleaning up is to practise basic hand hygiene,” Dr Reid says.

“Always wash your hands using soap after being in contact with contaminated water, and after cleaning up areas affected by flooding. It’s also important not to allow children to play in flood-affected areas until the clean-up is complete.

“In general people should avoid rivers and beaches for at least two days after any significant rainfall event. It’s not safe to drink water from rivers or use the rivers or estuary for recreational activities.”

For more detailed information on flooding and health please visit the Manatū Hauora/Ministry of Health website.

New Brighton road closure

New Brighton Road, from Kingsford Street to Lake Terrace, is closed due to flooding.

Wastewater issues

We are aware that some parts of the city are experiencing some wastewater issues. 

 This is because stormwater is getting into the wastewater network.

All our wastewater pump stations are working but they are struggling to keep up with the volume of water being flushed through the network.

This issue should resolve itself once the rain stops and the surface flooding on the roads starts to drain away.

If you are experiencing issues with your wastewater pipes, please hold-off calling the Contact Centre for help. That is because at this stage there is nothing we can do. We just have to wait for the rain to stop.

The wastewater network should start to recover once the rain has stopped, but it could take a few hours.

People who are having issues with stormwater backing up their pipes will know they are having issues and won’t be able to flush their toilet.

People who aren’t affected can flush as normal.

Wigram road closures

A number of streets in the south Wigram area are being closed due to flooding. The closed roads lead into the area bounded by Springs Road, Corsair Drive, The Runway, and Awatea Road.

Weather update

Computer models show the rain hitting Christchurch and Banks Peninsula is likely to continue until about midnight tonight.

“The rain has been heavier than was forecast and there are pockets of flooding across the district. The flooding has been exacerbated because the ground was already so saturated,’’ says Civil Defence and Emergency Management Manager Brenden Winder.

“The rain isn’t expected to let up until tomorrow and with high tide due around 3pm this afternoon, it is likely that we will see more flooding yet around tidal areas and the rivers.

“On the whole the stormwater network is holding up well given the volume of rain we have had this month.

“There is a lot of water on the roads and we have closed a number of streets around the city for safety reasons. Our roads are designed as a secondary flow for stormwater and in big rain events like this we expect to see them flooding. The water will drain away once the rain stops.

“Given the volume of water around the city it is very important that people drive slowly and take extra care travelling around the city. If you can avoid trying through ponded water, please do so. If you can’t avoid it, drive slowly so that you don’t push stormwater onto people’s properties.’’

Road closures for central city streets

The following roads are now closed across the city:

  • Avonside Drive from Woodham Road to Retreat Road
  • Oxford Terrace from Worcester Street to Gloucester Street
  • Cambridge Terrace from Cashel Street to Montreal Street
  • Edgeware Road from Hills Road to Geraldine Street.

  • Francis Avenue, from Warrington Street to 40 Francis Avenue
  • Emmett Street, from Briggs Road to Shirley Road
  • Carrick Street, from Flockton Street to Aylesford Street
  • Harrison Street, from Thornton Street to Aylesford Street

Update on state highways

Waka Kotahi NZ Transport Agency  is advising travellers in the South Island to check their route before they set off today.  

Snow has closed inland passes (Burkes and Lindis, and the road into Aoraki/Mt Cook) in South Canterbury/Otago and flooding has closed SH1 to Blenheim and Picton at Seddon in Marlborough. SH1 is likely to be closed all day at Seddon due to flooding.

It is possible that more highways may be closed due to flooding as the day progresses, says Waka Kotahi Journey Manager Tresca Forrester. 

“Please slow down and drive to the conditions if there is surface flooding to avoid making waves. People should expect roads that are open to be slower than usual with damage from last week’s storm creating some slower patches in many places across our network.”

Check what State Highways are open.

Busy time for Contact Centre

Our Contact Centre is receiving a high volume of calls. Please do not call the Contact Centre to report flooding on the roads unless there is a genuine safety issue. The roads will cope with stormwater ponding on them and the water will drain away once the rain stops.

It is important that we keep the phone lines free for residents who need help. We will prioritise responding to calls where safety is an issue or where people’s homes and businesses are threat.

If people feel their safety is at risk, they should call 111 immediately.
