Geraldine Water Supply

Water Supplies

History of Geraldine Water Supply

Geraldine’s public water supply was initially installed during 1930 with the oldest pipes recorded as being installed in 1938.  Historically the source was a bore adjacent to the Waihi River within Geraldine.  In 1978 the source was altered to shallow bores located north east of Geraldine, adjacent to Orari Back Road, and the Orari River.  

Where does Geraldine's water come from and is it safe?

Geraldine's water comes from four 12-metre deep wells near the Orari River and goes through an ultraviolet (UV) light chamber before being pumped into a reservoir located above ground within the Talbot Forest Reserve. Chlorine is used to prevent the water getting re-contaminated on its way to your taps.

From the reservoir it is supplied to Geraldine using gravity only. This means that the water pressure is mostly dependent on the height difference between the reservoir and your property.

The UV treatment plant kills giardia and cryptosporidium and has been designed to meet the Drinking Water Standards for New Zealand.

The Geraldine Water Supply serves a population of approximately 2,120 people.

Who looks after the Geraldine water supply?

The Council owns and maintains the water supply network from the source including the connections from the street mains to all serviced property boundaries plus tobies and valves.

Council uses contractors to carry out maintenance works.

Occasionally we may have to shut down a water main to carry out some maintenance, which means you will have no water. When this happens, we try to keep any disruption to a minimum and let people know in advance that their water is going to be turned off. It might be by letter, an advert in the paper or on the radio or a combination of these. However if you need a continuous supply of water then please you make your own storage arrangements.

What are your responsibilities?


You are responsible for all water assets from your toby to your taps.

If you have a shared right of way it is common that the water supply within that right of way is a combined water service for all users. Users who use this pipework are responsible for its operation and maintenance. As this supply line is beyond the road boundary it is not the Council's responsibility.

Conserve water

  • Water is a limited and precious resource. The Council is only allowed to take so much water from the rivers and groundwater, so we all need to use water wisely. We constantly check our pipelines to ensure that we do not have any leaks and we ask you to fix any leaks you may find on your property.
  • The Council will get in touch with you if we become aware of water wastage on your property and will ask you to fix it. If it continues to be at unacceptable levels then enforcement action may be taken.
  • If you are a consumer who uses a lot of water you may have a meter installed on your water supply connection.


Dry weather conditions may result in short supply because of low river levels and excessive use by consumers. When this happens hosing restrictions are put in place to help keep the demand for water down.

Restrictions are advertised in the newspaper and on our website

Backflow Prevention

What is backflow?

Backflow means that water is flowing in reverse to the normal direction ie: it is coming from your property back into the water mains.

How does it happen?

It can come from a private well on your property, or from hoses left in ponds or pools, a home irrigation system or an incorrect air gap on a header tank. It's really important that you know of the risks as contamination of water supply due to backflow can be a potential health hazard. As a Council we can ask to have an assessment of the risk of backflow from any property and to require an appropriate backflow prevention device or system be installed at the property owner's expense.

Report or Repair Faults

Please let us know if you see a fault in our water system such as burst pipes, leaky water mains etc. If the fault occurs inside a property's boundarythen it is up to the owner to fix it but you can contact the Council for technical advice.
