Ross Water Notice & Chlorination Concerns

Update from 12 Oct 2017

Notice regarding chlorination of Ross water supply

Westland District Council would like to respond to concerns which were printed in the Hokitika Guardian on Wednesday 11 October 2017 regarding chlorination of the Ross water supply.

Chlorine has typically been added to the Ross water supply. This was standard practice prior to the incident and no additional chlorine has been added since.

The Ross Water Treatment Plant continues to meet the bacterial compliance standards in both the network and the water treatment plant itself. Furthermore, the levels of chlorine in the town reticulation are well within the taste and odour thresholds of the Drinking Water Standards and are significantly below the maximum acceptable values.

Westland District Council has not received any service requests to investigate chlorine issues for the Ross township in recent months. If any Ross residents have genuine concerns regarding the chlorine levels, you are more than welcome to log your concerns via our service request system. When service requests are logged in our system this allows us to send a contractor out to follow your concerns up and take a sample. There are many ways that you can log a service request. You can call our Customer Service Centre on 03 756 9010, you can visit our Customer Service Centre in person, or you can now log service requests online via our website:

The ability to log a service request online is a new service that Council has introduced in the last week with the launch of our new website.

Regarding the smell of Chlorine, typically if Chlorine can be smelt (and the chlorine is within the acceptable levels which our data shows that it is) this is a good sign. The process of the chlorine eating up bacteria releases a chlorine smell which indicates that the chlorine is working and is doing the job that it is meant to.

We trust this information allays concerns, however, as noted above, residents are more than welcome to log a service request if they would like us to dispatch a contractor to investigate concerns further.

Update from 16 Aug 2017

Ross residents are to be commended on their measures taken to decrease water consumption. Over the last week it looks like you halved your average water consumption so this is a great effort! 

We apologise for the ongoing inconvenience, please continue to conserve water until further notice.

Water Conservation Tips

That an average person uses 250 litres of water per day.
• A typical dishwasher consumes about 16 litres of water per load of dishes
• Washing your car with a hose can use up to 400 litres of water
• Having a short shower instead of a bath can save up to 120 litres of water
When an official conserve water notice is in place, this means you need to reduce your discretional (i.e. non-essential) water use.
This may include:
Having shorter showers
Running your dishwasher less or washing dishes by hand (with plug in sink)
Avoiding washing your car 
Rinsing vegetables or brushing your teeth with the plug in the sink not the tap continuously running
Washing clothes by using a lower water setting on your washing machine
Every household uses water differently though so you will need to exercise your own common sense also.
Water savings are about preventing waste. Another good way to prevent water waste is to fix any leaky taps. The more water you save, the less you will pay (in hot water charges via gas or electricity). You will also ensure that there is sufficient water available for emergency purposes.
