South-West Wastewater servicing project



According to Brent Evans, Manager of Local Board and Stakeholder Liaison for Watercare, Auckland Council has forecast significant population growth in Auckland over the next three decades and beyond.

As Watercare provides most water and wastewater infrastructure services in Auckland, they are tasked with developing and implementing infrastructure solutions that can support this growth.
One of the areas where urban growth is expected to occur is in South-West Auckland, around Clarks Beach, Kingseat and Waiuku.
These communities have recently been connected to a new water supply system and have their own wastewater treatment plants.
However, the existing wastewater treatment plants will not be able to provide ongoing services for a growing population, and for this reason Watercare has established the South-West Wastewater Servicing Project.

project overview
The South-West Wastewater Servicing Project will look at the different ways that Watercare might be able to handle and treat the extra wastewater generated from growing communities as previously mentioned. They will also be taking into consideration how the growth in the other areas of Franklin (for example Pukekohe) may need to be accounted for. This project will be looking to identify the ‘best practicable option’ to manage the wastewater generated in these areas, whilst taking into consideration environmental, cultural, operational and economic factors.

current management
At present there are three wastewater treatment plants servicing communities in this area located in Waiuku, Clarks Beach and Kingseat.
There is also a small private treatment plant at the former Kingseat Hospital that services the residents and activities on the premises.
These treatment plants are all operating effectively at the moment, but as the population grows , more thought would need to go into how Watercare will manage the additional wastewater.

The aim of the project is to work in partnership with the community and mana whenua to identify the best practicable option to provide wastewater services for these communities.
Watercare says they are committed to working closely with the community to identify the best practicable solutions.
Throughout the project there will be opportunities to provide your feedback on the feasible options. If you would like to receive updates on the project please email us at with the subject line ‘sign me up’ to register or give us a call on 09 442 2222.

Since you’re here… we have a small favour to ask. More and more people want the Post than ever but advertising revenues across the media are falling fast. And unlike many news organisations, we haven’t put up a paywall – we want to keep our journalism as open as we can. So you can see why we need to ask for your help. The Post’s independent, investigative journalism takes a lot of time, money and hard work to produce. With investigative reporting, we often don't know at the beginning how a story will unfold and how long it might take to uncover. This can mean it is costly – particularly as we often face legal threats that attempt to stop our reporting. But we remain committed to raising important questions and exposing wrongdoing. And we do it because we believe our perspective matters – because it might well be your perspective, too. If everyone who reads our reporting, who likes it, helps to support it, our future would be much more secure. For as little as NZ$5, you can support the Post – and it only takes a minute. Thank you.
