Water

In March and April 2021, Carterton was under a series of boil water notices due to intermittent low level E. coli readings taken from sampling points connected to its urban drinking supply.

The Council has written a full and comprehensive public report of the investigation and remedial work taken during the boil water notice, and our ongoing plans for our water infrastructure. This is now available to view here

What are the current water restrictions?

As of 28 January 2021, urban residents are asked to restrict water use to handheld hoses only on alternate days (odd numbered houses on odd days, even houses on even days).

Where does our water come from?

Water supply for the Carterton district comes from the Kaipatangata Stream and two underground bores. These sources are dependent on rainfall.

Carterton’s main water supply at the Kaipatangata has relatively little storage capacity so daily collection and treatment of the stream water is closely linked to the volume of water being consumed.

In 1990 the Council undertook the construction of its supplementary bore system. The main purpose of this system is to ensure that during times when the quality and quantity of the Kaipatangata supply is not adequate, the supplementary system can be brought on stream to ensure that residents have water f

or domestic use and township has sufficient water available for fire fighting purposes.

What increases our water consumption so drastically over the summer months?

During the summer Carterton’s water consumption almost doubles that consumed over the winter period. This can be attributed to high levels of garden watering, and other usage such as swimming pool filling and topping up.

A garden hose can easily deliver 20 litres of water every minute; that is equivalent to a bath full of water every five minutes, so it’s easy to see how careless watering or leaving the tap on by accident can waste a lot of water.

Conservation Tips

More than 70% of indoor water use occurs in the bathroom and more than 20% occurs in the kitchen and laundry.

When filling swimming pools avoid filling to the top to minimise wastage by water slopping over the top.

How will you know that water restrictions have been imposed?

The water restriction wheel located on the Carters building on High Street will display the level of water restriction imposed.
