Water maintenance projects
We're carrying out maintenance of our water-related infrastructure throughout the year. This page outlines the work currently being done.
Starting in April 2023, Council’s contractors are carrying out work to renew water supply mains and aging pipelines in Paekākāriki, improving network resilience in the village. We’ll be carrying out this work:
- along the full length of Aperahama Street
- on Tilley Road, between the intersection with Ocean Road and approx 67 Tilley Road.
Pipes will be laid in roads and berms. We’ll be using open excavation method of construction, so there will be some unavoidable disruption to the community.

We expect work to take about 12 weeks, weather permitting, completing around the end of July.
We’ll being using temporary traffic management to ensure the safety of our workers and community, so delays, detours and road closures may be needed at times. We’ll be doing our best to keep these to a minimum.
Water shut down
When we’ve finished installing the pipes, we’ll need to shut down the water supply in some areas to connect the new pipes to the network. We’ll let affected people know in advance of any water shut down.

Since January 2023, Council’s contractors have been renewing 800 metres of water supply mains and aging pipelines along Te Moana Road in Waikanae. Our contractors are carrying out this work between Walton Avenue and Marae Lane.
Pipes will be mostly laid in the roadside berm where possible, but we will need to lay some under footpaths and across some roads. We’ll be using open excavation method of construction, so there will be some disruptions. Our contractor will contact residents if their water supply will be affected.
Weather permitting, we expect this work to finish in May 2023.
We’re upgrading the stormwater network in Old Beach, Waikanae, in the green space from Rauparaha Street to Huiawa Street.
The project is going well, and our contractor has laid most of the new stormwater pipes. These new pipes have larger capacity than old ones, and will help reduce flooding after heavy rain. Over the next six weeks the contractor will be working on building the outlet connecting to the stream.
We expect this work to be complete around the end of May 2023, weather permitting.

We’ll being using temporary traffic management to ensure the safety of our workers and community, so please follow workers’ directions on site. We’ll be doing our best to keep any delays to a minimum.

We recently completed a 10-month, $1.6 million refurbishment of a clarifier at our Paraparaumu Wastewater Treatment Plant.
A clarifier is the secondary stage of the wastewater treatment process. Its settles and removes biological solids from liquids, which both then undergo further treatment before being discharged. We carried out a routine inspection of the clarifier last year and identified although the foundation structure was in good condition, the lining of the tank was damaged.
Without action, this would lead to more damage of the foundation structure. We emptied the tank and cleaned it, before laying several coats of new epoxy lining. We also renewed the bridge assembly (which circles the tank and removes solids).
The 43-year-old, 1.1-mega-litre clarifier is now as good as new, and set up to serve our community for another 50 years.
