Connecting your home

Properties with an existing water supply point

Check if your property has an existing water supply point (see picture). Your supply point should be located at the front of the property on the boundary and has a blue lid and tail pipe.

If your building consent has been granted you or your plumbing contractor can connect to your supply point if available. No application form is required.

Submitting As-Built to the Council

Restricted supply

We have two types of water supply connections in our district - on demand (unrestricted) and restricted.  Restricted connections have a restrictor at the point of supply. If you are on a restricted supply you will:

  • Receive a fixed daily allowance delivered to a holding tank on your property over a 24-hour period via a restrictor.
  • Have water provided to you as “units”. The units that you get depend on the water supply scheme that you are in.
  • Have a tank and a pump installed to ensure you have the minimum water storage required in your area. We recommend installing a tank that is large enough to hold at least three day’s water storage. The more on-site storage you have the better off you will be when the scheme is down for periods of time and the quicker your system will recover. (This information is available in LIMs and PIMs.

At or outside boundary

Fig. 2 Sections in blue are owned by the Council and will need to be installed by a council approved installer - Sections in pink are the components owned by the property owner and it is their responsibility to install and maintain.

Need more water?

If you use more water than your allocated amount and your tank isn’t large enough, your tank could run out of water. If this happens, you need to wait until the tank slowly refills.

In more urgent cases you can contact Council and request your tank be refilled and be charged for the Council’s costs. Alternatively you may pay for a private company to fill your tank.

Your responsibility

The point of supply is the point after which responsibility for ownership, maintenance and repair passes from the council to you.

  • Do not allow any other party to use your point of supply unless this is approved by the council and keep the area around your equipment free from obstruction.
  • Do not tamper with the restrictor as it is an offence under the Council’s bylaw and you may be charged for repairs or replacement, and could be prosecuted.

Please check with before undertaking any excavation work, including planting trees, to find out whether any underground pipes may be in the area. You can also phone beforeUdig on 0800 248-344 or email: If your excavation work causes damage to a council pipe, then you will be liable for the cost of repairs.

Our responsibility

  • Restrictors will be supplied, installed and maintained by the council and will remain council property at all times.
  • A restrictor can be tested if you have concerns about its accuracy by applying to the council for the testing to be done.
