Permanent chlorination provides safe drinking water for Hurunui
In July 2017, the decision was made by the council to begin chlorination of water supplies currently without chlorine. Chlorine provides a continual protectant that ensures any contaminants entering the district’s pipelines are removed and do not put our communities at risk.
Water supplies that are sourced from the Leithfield bore and Racecourse Road bore will commence chlorination from the beginning of December 2017. This includes the Amberley and Leithfield areas, as well as the southern part of the Ashley Rural Water Supply.
Chlorination of the Hawarden and Culverden supplied is expected to commence later this year.

Are we on Miox? Is our water currently treated? Will we be going on continuous chlorine?
And the answer to these questions isn’t straight forward… It depends on where you live on the scheme and which water source supplies your property.
Please refer to the attached map:
If you live in the ‘pink’ area, then your water comes from the Racecourse Bore. This water is currently untreated but will be chlorinated from mid October.
If you live in Leithfield Beach or the ‘green’ or ‘yellow’ areas then your water is currently chlorinated and will remain so.
If you are in the ‘blue’ area your water is supplied from the Leithfield Bore. This water is currently untreated but will be chlorinated from mid October.
If you live in the area below the blue shading, then your water is supplied from the Ashley River intake and this is treated with MIOX and Ultra Violet Light. There are no changes planned for this treatment regime.
If you are in a blue or pink area you should not be smelling or tasting chlorine currently. We have had a handful of customers report that they are getting a chlorine taste/smell – if you are experiencing this phenomenon too then we would like to hear from you so that we can get to the bottom of this. Please call us on 314-8816 and we will send out a utility officer to take some samples.
- There are currently 13 Council owned water schemes in the District
- Extracting water from 24 different sources.
- Water Testing Reports
The schemes are overseen by Water Committees with delegated responsibilities for the planning and development of their schemes.

A reminder that it is an offence to tamper with the restricting device that controls the flow of scheme water to your tank.
In accordance with our Fees and Charges, replacement part costs and a fee for resetting the restrictor can be charged.
Your tampering negatively impacts on the supply to others.
"I'm on a restricted water supply" - what does this even mean?"

Waiau Rural, Blythe, Hurunui 1, Kaiwara, Parnassus, The Peaks and Lower Waitohi Rural Water Supplies
1 September 2017
Residents on the Waiau, Blythe, Hurunui 1, Kaiwara, Parnassus, The Peaks and Lower Waitohi Rural Water Supplies were notified in 2013 about the installation of their MIOX water treatment systems. All MIOX water treatment plants have been installed and are operational but these Boil Water Notices will remain in place. This is so that we can continue to monitor the water quality as well as the performance of the new treatment system.
Residents on these water schemes are reminded to boil their water, as the permanent boil water notice will only be lifted once we have fully commissioned these water treatment plants.
If you have any further queries or concerns or have not received your postcard and would like to have one sent out to you, please feel free to contact us on 03 314 8816
Hurunui District Council Water Supplies
Nitrate Test Results of all Treatment Plant Water - 2 March 2016
All of Hurunui District Council's Water Treatment Plants were tested for Nitrate levels during October 2013. We have the 2014 test results for nitrate levels at all our water treatment plants and all levels fall comfortably below the values as set by Drinking Water Standard Guidelines. You can see all the Nitrate test results here. These tests will be repeated next October (October 2015) to ensure that all levels remain within the Drinking Water Standard Guidelines.
Rural Water Supply
We have tried to reach as many customers on our Rural Water Supplies as possible with our Restricted Water Supply Information Pamphlet. To see a copy of the pamphlet, just click here. This not only covers some background information and maintenance advice, but also instructs on how to do a flow check to ensure you are receiving the correct amount of water as well as gives some good water management suggestions (including the use of "tell-tales").
Since all rural supply customers are required to ensure they have three days storage capacity, below we have some average water usage figures so you can work out how many water units you need for yourself and your stock. Capacity is linked to consumption demand, for instance dairy cattle require 70 litres per day each so consumers need to ensure they have purchased sufficient units of water to cover their needs.
Daily stock Requirements from the Canterbury Natural Resources Regional Plan:
- Sheep (in milk - dry pasture) 15 litres per day each Sheep (not in milk - dry pasture) 6 litres per day each Lambs (dry pasture) 2 litres per day each
- Dairy Cattle (in lactation) - 70 litres per day each Dairy Cattle (dry) - 45 litres per day each Beef Cattle - 45 litres per day each Calves - 25 litres per day each
- Horses (working) - 55 litres per day each Horses (grazing) - 35 litres per day each
- Sows - 25 litres per day each Pigs - 11 litres per day each
- Poultry - (per 100 birds) - 30 litres per day Turkey - (per 100 birds) - 55 litres per day
- Households 230 litres per day per person
Please calculate your daily requirements against your current purchased supply. If you have any queries please contact 03 3148816
Swimming Pool Fill
Please note due to the high water demands over the months of November - February swimming pool fill requests are subject to water availability.
On-demand water is supplied to 8 of the Urban Communities in the District from 7 high pressure schemes consisting of 9 water intakes and 60 km of pipe.
Other small Urban Communities:
- Gore Bay
- Greta Valley
- Amberley Beach
- Motunau Beach
These Communities are supplied via tanks from restricted rural supplies. All Rural Communities in the District are serviced by Council operated restricted-flow water supplies providing water to consumers as “units” of water supplied into individual tanks. One unit is 1800 litres supplied over 24 hours, except for Balmoral and Amuri Plains, where a unit is 1000 litres per day. The Hurunui and Cheviot Rural Water Schemes cover four separate supplies within each of their areas. The Ashley Scheme also has four distinct sources and includes part of the Waimakariri District within its boundaries.
All townships with on-demand supplies, except Leithfield Beach have metered connections and charges are made on actual water consumption. The metres are read in April and May each year and ratepayers are advised of their annual consumption and costs in their first quarterly rate demand each year.
Having consumers represented at the local level in Water Committees is considered to be one of the main strengths of the current organisation and there is no intention to diminish the impact and contribution of these Committees. However, with rural water rates ranging from $130 a unit to $850.37, there is the need to consider if there is a benefit in funding all schemes by a District-wide rate to improve economies of scale.
The Council intends to retain the ownership of all public water supply assets on behalf of the Communities that these facilities serve. Asset management, basic design work, contract documentation, tendering, record keeping, operation and routine repair and maintenance is carried out by the Council's staff.
Most of the network reticulation is in good repair and operating under a policy of renewal when necessary, reticulation should remain serviceable indefinitely. Pumps, controls, telemetry (data sent back to the Council office by radio) and water treatment devices are repaired as the need arises and are replaced as the benefits of repair are outweighed by replacement – usually every 12 – 20 years. Reservoirs, weirs, bores, and ponds are maintained on an ongoing basis. Ages of on-demand water networks is quite recent, with the earliest networks dating to 1955 (Amberley).
This activity provides for the collection, treatment and disposal of sewage from urban areas of the District in seven separate schemes comprising 14 sewer pump stations and 65 km of pipe works. (Amberley and Districts, Cheviot, Greta Valley, Motunau Beach, Hanmer Springs, Hawarden and Waikari).
Each scheme is self funding with revenue obtained by uniform annual charge on each rateable assessment having access to the respective scheme.
