We are responsible for the maintenance of 120km of trunk mains and 560km of service mains piping water throughout the district. This includes the mains and pipes leading up to your boundary and your toby or manifold.
If you notice a water leak on a road, in a park or reserve, or on someone else’s property please let us know – giving as much information as possible about the leak (e.g. location, size). If the leak is on private property, we'll get in touch with the land owner to get it fixed.
Some leaks require urgent attention, while others can be fixed under normal response times. Please call us on 06 759 6060.
Should I call NPDC or a plumber?
If your toby/manifold is leaking try to establish where the leak is coming from. If the leak comes from the pipes or fittings inside the toby/manifold box or from the street side of the toby/manifold box, you should contact NPDC to report it. If the leak is on the pipe on your property side of the toby/manifold you will need to contact a plumber for assistance/advice.
If your property has a water meter you can determine if the leak is on your private line or on NPDC's line by checking your water meter. Take a reading of the meter in the evening and another in the morning, ensuring that no water is used overnight. An increase in the reading overnight indicates that water has passed through the meter, and that there is a water leak on your side of the meter, in which case you should contact a plumber for assistance/advice.
Water mains refreshing, or flushing, happens when we open up hydrants for up to 20 minutes to run fresh water though pipe networks that are not frequently used (e.g. in cul-de-sacs and dead end roads).
This sometimes causes water pressure to drop, however it seldom drops below the minimum level we've set.
