What’s proposed?
The Council is seeking community feedback on whether to introduce chlorination to some community water supplies.

Selwyn District Council is committed to providing our communities with safe drinking water. Across our 30 water supplies we currently use a variety of water treatment methods including secure ground water (to meet current New Zealand Drinking Water Standards), Ultraviolet (UV) disinfection, selective abstraction and filtration, and chlorination.

Following the Government’s inquiry into the Havelock North drinking water contamination incident, councils have been urged to ensure the protection of drinking-water sources and effective treatment of supplies for the protection of public health. In response, the Council has accelerated the programme to install UV treatment on secure bores.

Consideration is also being given to chlorination, to provide additional protection. Chlorine provides residual treatment in the water reticulation system which UV does not provide, minimising the impact of any contamination which may enter the distribution system. It is widely used in New Zealand drinking water supplies and is currently used on five supplies in Selwyn, and we are adding chlorination to two further schemes.

The Government’s position on the chlorination of water supplies is not yet known – and chlorination may become mandatory. If it is not made mandatory, a range of options are available to the Council.

The Council is now seeking comment from the community on options for introducing chlorination to community water supplies.

What are the options?

  1. Introduce chlorination for water supplies which would receive the greatest benefit, based on a risk assessment

  2. Introduce chlorination for all Council water supplies

  3. No additional chlorination

How will this be funded?

The cost of water treatment is funded by the district-wide rate paid by all properties on a Council supply. The proposal to introduce limited chlorination, as in option 1, will increase the rate by $10.

What's your view on the proposal to introduce chlorination treatment to Council's community water supplies?
