Bin Enquiry FormWe buy treated water from Greater Wellington Regional Council (GWRC) and distribute it to you via our network of 685 km of underground pipes, 24 storage reservoirs and 13 pumping stations. We also make sure it meets the Ministry of Health’s drinking water standards.
We all have a part to play in conserving water, especially in the garden and during the hot summer months.
Every summer, during daylight saving months (September-April) there are garden watering restrictions.
The restrictions allow you to use a single watering system (sprinkler, irrigation system, soaker hose, or unattended hose) between 6-8am and 7-9pm on allocated watering days:
Summer’s temperatures and dry winds increase evaporation. There's also less rain which increases water usage and can mean shortages.
As well as following garden watering restrictions during daylight saving, you can take further steps to save water in your garden:

Here's how you can help protect the water supply system and our environment:
By taking these steps you can help maintain the safety of our water supply system and minimise future costs to ratepayers.
You are responsible for all water supply plumbing fittings on your property after our ‘point of service’.
This is the shut-off valve (known as a toby) which is situated on or close to the street boundary of your property. We’re responsible for maintaining the water supply system up to and including the point of service.
We aim to provide you a first-rate and uninterrupted water supply service, and to meet the following goals:
Water will:
To maintain our commitment to water safety and to maintain a safe water supply that meets New Zealand Drinking Water Standards, the water supply needs to receive Receive at least a Bb (satisfactory, very low level of risk) grading from the Ministry of Health.
Chlorine
In August 2017, in response to concerning levels of bacterial indicators in the aquifer, the GWRC approved the ongoing chlorination of Lower Hutt drinking water.
Wellington Water sought advice from independent experts on the results of investigations into the aquifer. They advised that relying on the aquifer’s natural filtration processes is unlikely to be sufficient to manage potential public health risk.
Ultra Violet (UV) treatment
As well as continuous chlorination, Ultra Violet (UV) units are used at Waterloo Water Treatment Plant. UV treatment provides another layer of protection against potentially harmful organisms in our water supply.
Fluoride
Most of Lower Hutt's drinking water supply has added fluoride, except for Petone and Korokoro which have a long history of unfluoridated water.
For more information on fluoride in our drinking water see Wellington Water.
To find out more about the health effects of fluoride or information on the use of fluoridated water with baby formula, see Ministry of Health.
