If there are stormwater, water and/or wastewater pipes near where you intend to do building work, you need to talk to us.
Use the Council maps app to find out where the pipe and drains are on your property. You will need to double check pipe location by getting a copy of the as-built plumbing and drainage card. In some cases our records may not suffice and on-site investigations will need to be made.
A Project Information Memorandum (PIM) will also identify if there is any water, stormwater or wastewater system under your proposed building site. There are benefits to applying for a PIM early during the design stage as a PIM provides:
The PIM either confirms that you may carry out the building work (subject to the requirements of the building consent and to all other necessary authorisations being obtained), or gives you notification that building work may not be undertaken.
We maintain a network of pipes for sewer, stormwater and water to safeguard the community from disease and protect our environment and properties. When these pipes fail or require upgrading we require access to carry out the necessary work. Approval to build over pipes will not normally be given if the integrity of the system is compromised in any way.
Have a suitably qualified person prepare site and foundation plans of the building and accurately plot the pipes in relation to your building work. Our records should be treated as a guide only. If doubt exists, contact us as there are various methods available to locate the pipes. It is the property owner's responsibility is to ensure that these service pipes are not built over.
We generally require the structure to be located a minimum of the greater of the following two distances:
In exceptional circumstances we may allow buildings or additions to be built over or near pipes, In cases where approval is granted, costs to meet conditions must be met by the applicant and these can be significant.
If stormwater, water and/or wastewater pipes are under the ground where you want to build, you have three options:
Ideally all pipe work should be within the road reserve, but this is not always possible. Under the Local Government Act, we have the right to have pipes on private property, and to maintain and protect them. Many pipes were installed within private property by the subdividers of the land and we inherited these pipes.
In New Plymouth District there are many kilometres of water, stormwater and wastewater pipes. Some of these pipes are within private property and although some are within registered easements, many older pipes are not but they are legally allowed to remain. We occasionally require access to these pipes for repair or replacement.
