Water, Sewer and Stormwater Connections
This page provides information about water, sewer and stormwater connections, and links to application forms. It also lists the criteria for Building over Public Mains, Encroachment upon Underground Service Easements or Corridors or any Proposed Relocation.
Answer three questions first
There are three questions you need to answer first. Do you require:
- A supply connection/disconnection into or from Council’s underground service network of sewer, water or stormwater to your property or habitable dwelling
- A water meter installed on a new or existing water connection
- The raising or lowering of a manhole
If the answer is yes to any of these questions, then you will need to apply to us for this to be done.
Do you want to see where our pipes are? Then use our Porirua Pipeviewer maps.
The service models have been combined with Google map, Google Earth, and Street View for an easy visual understanding. Once into the model simply click on the Map Layers on the left hand side. They can turn on or off a range of interesting attributes related to the infrastructure servicing the city.
By clicking on any pipe within the network a range of options are presented in a pop up window. This includes information relating to the asset and incorporates a video showing the insides of the sewer line. Engineers use this information to assess the pipe's deterioration and structural integrity.
- All works carried outside of the property boundaries such as in road reserve or within legal service easements or within underground public utilities corridors (such as public mains crossing a private property) shall be carried out by Council's Works Operations and will need to be applied for.
- All other private works required for domestic service connections which do not directly access or interfere with the mains or network contained within the property boundaries shall be carried out by a suitably qualified and registered professional.
All works associated with the connection/s requested will be at a cost to the applicant.
Applications for individual connections or the raising or lowing of a manhole shall be made using the forms applications for Raising or Lowering of Manholes or Water, Sewer or Stormwater Supply Connection.
Quote for service
You will be provided with a written quote of the installation costs of the proposed work, together with a Development Contribution fees notice and schedule if applicable.
Once you have received the quote, you will need to acknowledge acceptance of the quote in writing. Return the signed quote to us and we will then issue you with an invoice in accordance with the quote cost. Alternatively you may personally deliver the completed quote along with your payment.
Development Contribution Fees
We will check our records to determine if any development contributions are outstanding or payable in relation to your application. You may have already been notified of such through an associated Building or Resource Consent application process.
If the development contribution payable is not paid, the Council may under section 208 of the Local Government Act 2002;
- Withhold a service connection to the development.
For further information, go to our Development Contribution Policy page.
The connection work will normally be completed within 10 working days of payment of installation and Development Contribution charges.
Application to take water from a Hydrant
Any water usage from public utilities apart from authorised connections is prohibited.
Any request for the taking of water from the network for external use , such as water from a hydrant or water extraction for the purpose of water cartage or tanker use, apply to us for approval.
Building over Public Mains, Encroachment upon Underground Service Easements or Corridors or any Proposed Relocation
If you are proposing to build on or develop land, you need to be aware of the following restrictions on what can be done where there are existing Council service systems on or adjacent to that land.
Building over public underground service mains and/or encroachment upon Council service easements or corridors or load surcharged onto those assets by any structure or part of a structure is prohibited. (Note: The surcharge line extends upward at 45 degrees from the bottom of any public water, sewer and stormwater service). Public mains means Council water, sewer and stormwater services.
There is a limit on how close to a public main you can carry out building or earth developmnent work. A minimum 3m width easement, 1.5m either side of the main and no closer than 1.5m to any structure or part of a structure is secured over all public services crossing private property at development stage whether the services are existing or new.
Where the pipe is deeply laid, or is a large diameter pipe the easement will be larger than 3m, as approved in writing.
Proposed Relocation of Mains
If you are proposing the relocation of existing public mains, your proposal must meet the following criteria:
- It must maintain the integrity of the existing networks capacity and flow rate.
- It must be proven to be an over all advantage to the existing network.
- It must not be deemed to cause of be the cause of higher initial or on going maintenance or replacement cost.
- It must not restrict, hinder or impede 24 hour access to the mains or maintenance structures.
In your application for relocation of public mains you must provide Council with a detailed report addressing and satisfying all the above criteria and including:
- Analysis and specific tests carried out on the network by a suitability qualified engineer experienced in underground services.
- The tests and analysis is to include the known and possible up and down stream effects the relocation will or could on the network; and
- Detailed designs prepared by a suitably qualified engineer showing the proposed relocation.
- The appropriate "Statement of Professional Opinion” form, prior to any acceptance by Council, and prior to the start of any construction works.
All costs associated with the proposed relocation including works and Council officer time is the applicant's responsibility.
