The Henderson-Massey area is undergoing significant growth as the population of Auckland spreads and intensifies. We have been investing to ensure water and wastewater services keep up with new development.
In the past decade, a new wastewater storage tank was constructed at The Concourse to reduce wet weather wastewater overflows into the harbour. Several years ago, a similar below ground storage tank was installed further up the catchment in Harold Moody Reserve helping to reduce wet weather overflows into a tributary of Henderson Creek. A new gravity pipeline has also been installed to service new development in the Redhills area. This connects to a new interim pump station and a rising main to the Massey pump station. Further work has been done on the Te Atatū Peninsula to reduce overflows onto the local boat ramp. The most recent wastewater upgrade was the duplication of the wastewater main around Lawsons Creek.
Wastewater from private residences and non-domestic sites goes into the wastewater network and is pumped to treatment plants for treatment and disposal. The network is focused on the Henderson Creek catchment area (see below map). In the north, pump stations in Te Atatu North and Central, Colwill Road and Darcy Place transport wastewater to the storage tanks at The Concourse. From Massey West, Ranui, Lincoln and Henderson, wastewater is gravity-fed along the large Swanson and Glen Eden lines to The Concourse. From there it joins the western interceptor line to Te Atatu South and travels to the Māngere wastewater treatment plant.
There are plans to expand the capacity of the wastewater network. The
Northern Interceptor project will divert wastewater from Massey North to the Rosedale wastewater treatment plant in Albany. This will reduce pressure on the wider network and the local area.
Drinking water comes from the Waitākere and Hūia water treatment plants. It is distributed to the southern area via the main trunk water line which travels along Henderson Valley Road to the Waikumete reservoir and along Lincoln Road to the booster pump station on Triangle Road. In the west, it comes to the Massey High School reservoir then travels north along Don Buck Road. Water reservoirs are placed along the network to guarantee supply during times of peak demand and to smooth flows during the day. We plan to build a
new water treatment plant and storage reservoirs at Hūia. This infrastructure will have significant benefits for the area.
