Our teams are out across Tāmaki Makaurau delivering Watercare’s $13.8 billion, 10-year infrastructure programme — building resilience, boosting capacity and supporting our growing city. With 110 projects underway across the region, there’s a lot happening. To give you an idea, here’s a snapshot of five projects.

North

Waiwera and Hatfields Beach

We’re delivering a $45 million programme to replace and upgrade critical water and wastewater infrastructure in Waiwera. This work includes constructing a new wastewater pump station, a wastewater pipeline and a new watermain.

Crews are currently installing sections of the 4.5 km wastewater pipeline along Hibiscus Coast Highway and Weranui Road. Early works for the new Waiwera Pump Station, located at the Waiwera Wastewater Treatment Plant, begin in February 2026. The programme is on track for completion in December 2026.

Together, the Akarana Booster Pump Station, the Waikōwhai Pipeline, and the Owairaka and Wesley watermain upgrades will cater for growth and strengthen network resilience.

Crews are currently completing watermain upgrades on Denney Avenue and May Road, and commissioning fo the Akarana Booster Pump Station is now underway.

Commissioning of the new pipelines and watermains is scheduled to begin in March 2026.

West

Titirangi, Glen Eden and Laingholm

We’re upgrading sections of the Nihotupu 1 pipeline, which supplies water to around 18,000 homes in west Auckland. The original cast iron line, laid in the early 1900s, is being renewed to improve reliability. From February, crews are replacing sections along Withers Road, Kashmir Road and Nandana Drive. We are also replacing watermains in the area to avoid future disruptions.

The Nihotupu watermain upgrade is expected to be completed by July 2026.

South

Clarks Beach and Waiuku

We’re bringing an upgraded wastewater treatment plant and a new outfall into service at Clarks Beach – the first major milestone in our $500 million–plus Southwest Wastewater Programme. Once online, the plant will treat up to five million litres of wastewater per day to a high standard, with the outfall dispersing treated water around 100 metres into the Waiuku Channel.

We’re also installing a new tidal storage system at the outfall and putting the final touches on the next projects in the programme.

The upgraded plant and outfall are scheduled to come into service in June 2026.

Beachlands and Maraetai

We’ve completed the renewal of 6.2 kilometres of wastewater pipes in Beachlands and Maraetai as part of a $12 million citywide programme to strengthen Auckland’s wastewater network. Over the past nine months, our crews have assessed the condition of the network, relined 6.2 kilometres of wastewater pipes, rehabilitated 85 manholes and 198 household connections.

As part of this wider programme, we’re also carrying out investigations and renewals in Newmarket, along with pipeline CCTV investigations across west Auckland, which are expected to wrap up by the end of February 2026.
