What we are doing
We are upgrading the stormwater network in the Blockhouse Bay area. The upgrade is part of the Western Isthmus Water Quality Improvement programme funded by the Water Quality Targeted Rate.
Watercare and our Healthy Waters department will work together to deliver the project.
What the upgrade includes
There will be a new stormwater pipeline from Blockhouse Bay Recreation Reserve on Rathlin Street to the intersection of Exminster Street and Blockhouse Bay Road. We will connect private properties to this new network.
The new pipeline will connect to an:
- existing drainage outlet at the end of Gill Crescent in Gittos Domain
- existing stormwater outlet within the Blockhouse Bay Recreation Reserve.
What the new pipeline will do
Currently, there is a combined pipeline for stormwater and wastewater. The new pipeline will direct the stormwater and wastewater into separate pipelines. This will:
- prevent wastewater overflowing to Blockhouse Bay Recreation Reserve and nearby areas
- improve the quality of water flowing into Whau River and Waitemata Harbour
- increase network capacity to reduce flood risks on Rathlin Street.
How the upgrade will affect you
Reduced parking spaces
We will use part of the Blockhouse Bay Reserve car park (entrance off Rathlin Street) to store construction material during the upgrade.
Traffic management
We will work with Auckland Transport on a traffic management plan (TMP) to minimise disruptions. The TMP will keep road users and pedestrians safe during the upgrade.
Traffic in the area may be affected at times.
Access to properties and businesses
You can still access your property and use footpaths during the upgrade. Check signposts for closures or diversions.
Businesses can remain open.
Disruption during construction
There may be some construction noise, vibration and dust. We will monitor these to make sure they stay within the permitted limits.
Timeline
Works start in early February and we expect them to be complete by November 2025.
The work will take place from 7am to 6.30pm, Monday to Saturday.
