Corban Reserve stormwater upgrade project

​What we are doing

We have installed a new stormwater pipeline from Imperial Place to Border Road, Esplanade Reserve in Henderson.

Timeline

Stage 1 of the project is now complete.

Stage 2 works are in the planning stage. We expect them to be finished in mid-to-late 2025.

What the pipeline will do

The pipeline will:

• help prevent flooding
• improve water quality in Opanuku Stream
• improve the environment for people, birds and stream life
• the project will improve health and safety for pipeline maintenance workers.

It will also enhance green recreation areas and public walkways.

How we will do this

We are completing the upgrade project in two stages.

Stage 1

A new tunnelled pipeline has been installed from Imperial Place, along Border Road to the Opanuku Stream within Border Road Esplanade.

The completed works include:

• a new pedestrian bridge between Spode and Imperial Place
• a new boardwalk, concrete path and stairs connecting Taranui Place with Border Road Esplanade Reserve
• a new bridge and connecting footpaths constructed as part of uncovering and restoring Waitaro Stream
• a low-flow pipe installed from the new pipeline to the open-air section at Murillo Reserve to make sure water keeps flowing into the lower section of Waitaro Stream
• the new North Harbour No.2 watermain across the Opanuku Stream which was constructed at the same time.

Stage 2

We will decommission the old pipeline under Corban Reserve and the existing brick culvert under Henderson Valley Road.
