All on-site wastewater systems within Porirua, such as a septic tank or aerated wastewater treatment system - must be licensed by Porirua City Council.
If you’re installing a new system on a property, you must apply to us for a building consent and onsite wastewater system licence before the building is occupied. You may also need to apply for a resource consent.
Your onsite wastewater system must also meet the Wellington Regional Council’s Regional Plan for Discharges to Land (updated July 2014) - Rule 7 On-site sewage treatment and disposal).
To apply you’ll need to have an authorised person inspect your onsite wastewater system and sign the application form below. Each individual system needs a separate form.Send us the completed application form, along with the application fee of $113.00.
An authorised person is anyone recognised as being suitably trained or qualified to undertake maintenance on, or prepare appropriate reports, designs and assessments for onsite wastewater systems.
The manufacturers of systems and suppliers of services are the most knowledgeable about how their systems function and any remedial work that is required, so this makes them an authorised person. Other examples include drain layers and engineers who have training and knowledge of specific onsite wastewater systems.
Before engaging an authorised person, please ensure that they have knowledge and experience with your particular type of system.
