What we're doing to reduce taste and smell issues

The taste and smell of water will vary across Christchurch.

We’ve had lots of feedback from people saying the taste and smell of chlorine is strong and want to update you on what we’re doing about it.

From today, Council contractors are flushing pipes in areas most affected by the smell and taste of chlorine. As well as this, staff are working with the appropriate health authorities to explore how we can reduce the amount of chlorine being added into the water supply.

We'll be publishing some information in local media outlets over coming days so look out for that, and remember to keep an eye on our website which we'll be updating with new information. 

Why is the smell and taste stronger in some areas?
The amount people notice the smell and taste can, among other things, depend on how close they are to the pump station. Different pump stations are used depending on demand so you may not be getting water from the one closest to you. There is a map of the pump station locations on our website.

Another factor is the condition of the pipes. Chlorine reacts with a variety of naturally occurring materials in the pipe. It’s this reaction that can cause the variation in smell and taste in some areas and that’s why we’re flushing pipes in the worst-affected areas.

What you can do to reduce the taste
If you fill an open jug with water and keep it in the fridge over time the taste will reduce.

You need to keep lids off containers so the chlorine can evaporate over time.

What if it’s causing skin issues?
If you have any health-related concerns, you should contact your general practice team or family doctor first.

If you call your usual GP’s number after-hours your call will be put through to a nurse who can provide free health advice.  You can also contact Healthline any time on 0800 611 116 for free health advice.
