Between approximately 8 am on 25 June and 7 am on 26 June, the short outfall pipe discharged untreated wastewater into Tarakena Bay.

Signs are in place along the coastline to alert water users of areas which may be impacted by this event. Water quality samples will be collected from coastal locations once improved weather conditions allow. 

Check LAWA.org.nz before visiting beaches along the south coast.

Wellington Water crews responding to wastewater overflow on State Highway 2
Wellington Water crews responding to wastewater overflow on State Highway 2

Our team is responding to a wastewater overflow on State Highway 2 which has stopped this afternoon. The overflow was from a manhole on the southbound lanes close to the Ngauranga exit, discharging into the habour through the stormwater drains.

While the overflow has stopped, our teams are working to clear a blockage which still remains. They are working at pace to identify the blockage and get this cleared. 

One southbound lane clasure remains in place approaching Ngauranga while work is underway.

Water sensitive design

Water sensitive design (WSD) is an inter-disciplinary design approach, which considers stormwater management in parallel with the ecology of a site, best practice urban design, and community values.

WSD aspires to ensure multiple public benefits from stormwater management and to develop a unique ‘sense of place’ for our communities. It also seeks to deliver low risk and better return on investment for land developers.

We have released a new guideline to support the implementation of WSD in the Wellington region. The guideline is focused on delivering water quality outcomes through localising national and international WSD best practice to the Wellington region. The first version of our guideline covers four types of WSD stormwater treatment devices (also known as green infrastructure):

  • Constructed wetlands,
  • Bioretention (raingardens),
  • Vegetated swales, and
  • Pervious paving.

 

Wellington Water intends to continue to release practice notes in this area as our local WSD practice develops.
