The combined population of Wellington, Lower Hutt, Upper Hutt and Porirua produce about 145 million litres of wastewater every day . This water is treated at one of four plants - two in Wellington, one in Porirua and one in Lower Hutt - before being returned to the environment.
There is an extensive upgrade of the plant under way - you can read more details here.
The current consent for the Porirua Wastewater Treatment Plant (WWTP) expired in 2020. Prior to the expiry of this consent, Porirua City Council applied to Greater Wellington Regional Council for a new consent (a coastal permit) to discharge treated wastewater from the plant to coastal waters off Rukutane Point. While this process is underway, we continue to operate under the existing consents.
You can read more about the treatment process, the plant, the resource consents and the current application on Wellington Water’s website here:
For a healthier harbour and coastal waters, we need to reduce the amount of untreated wastewater overflowing from the network. Overflows happen when wet weather increases the amount of water flowing through the network beyond the amount the pipes can carry.
To reduce overflows, we’re planning to build a new storage tank in central Porirua, located north of the railway station.

Titahi Bay’s pipe network is being inspected as part of a project, called Knowing your Pipes, to improve water quality in the region.
The project in Porirua, led by Wellington Water, will involve crews checking pipes in the public and private network.
Some homeowners in Titahi Bay were contacted and had their pipes checked, using low-risk smoke testing and dye tracing. Thank you to those how have been involved and who have taken steps to make repairs.
Homeowners are responsible for the pipes from their home to the property boundary. If there is any cost to fix faults on private property, Porirua ratepayers will be able to apply for assistance to spread the cost via Porirua City Council rates.
The project has also identified work to be done on the public network and some of this is underway.

Any water that goes down the toilet, sink or any other drains in your home is wastewater. To find out where it goes, watch this video:
Key issues facing our city with regard to the three waters: drinking water, wastewater (all the water that goes down our sinks and toilets) and stormwater (rain water that runs off our roofs and streets).
Wellington Water are regularly monitoring and measuring water quality at Titahi Bay (and other points around the coast and in the harbour).

Boat sheds are normally used to store boats and their associated paraphernalia. But in the Wellington region, many people have set up home in their sheds to better enjoy coastal life. In the past this practice was low key and councils tended to turn a blind eye to it. But there are not a lot of coastal areas around Wellington and Porirua that are suitable to launch boats from so, by the 1990s, residential use of boat sheds had started to squeeze out the number of boat sheds available for storing boats.
Any sort of building on the foreshore restricts public access to and along that piece of coast. This is contrary to the principles of the Resource Management Act. On top of that, most boat sheds don't have toilets connected to a sewer. The Council now requires resource consents from people wanting to stay in their boat sheds, and is taking enforcement action against those people who break the rules.
