Judges Bay wastewater repair

Project overview

The unprecedented weather events of early 2023 caused an underground collapse under the Parnell Rose Gardens which in turn broke a wastewater transmission sewer line approximately 25 metres below the ground. Since this event occurred, we have had a temporary bypass in place.

Permanent repair

As the break occurred deep underground, we are unable to replace like for like without substantial disruption to the Rose Gardens. Therefore, we are installing a permanent solution that will include:

• A small pre-packaged submersible wastewater pump station on the North-Western corner of the Judges Bay Road Intersection with Bridgewater Road

• A rising main along Judges Bay Road to be installed by Horizontal Directional Drilling

• A gravity sewer along Cleveland Road to be installed by Horizontal Directional Drilling

Project update

We are pleased to advise that works are nearly complete on our Judges Bay wastewater repair project. The pump station has been successfully commissioned and is now operational.

We are removing the temporary pump station which was set up in the reserve since the original break to the pipe under the rose gardens in 2023. Once this is removed, we will reinstate the park area. While works are effectively complete, later this month we will return to install additional safety fencing around the new pump station.

Water quality testing will be taking place and once complete the black flag on SafeSwim will be removed.

Last month, members of our team along with the Pipeline and Civil team were joined by Deputy Mayor, Desley Simpson, members of the Waitematā local board and neighbours to celebrate the completion of the pump station.
