Water supply

We're responsible for supplying safe water to approximately 20,000 connections for household and commercial water use in our District. In Kāpiti all of our public drinking water is tested and treated with chlorine and high-intensity UV light and pH corrected to make sure it’s safe to drink.

Restrictions/Boil water notices

Everything you need to know about water restrictions and boil water notices in Kāpiti.

Ratonga | Services

Most properties in the Kāpiti District have water meters, and are charged for the water they use. Water rates help pay for water collection and treatment facilities, our water supply network (eg, fixing, upgrading and replacing pipes) and water conservation measures.

Where it comes from

Our water is sourced from various locations around the district and we're responsible for the management and maintenance of its assets like treatment plants, reservoirs, pump stations and the reticulation network.

What we do to it

At times the water you drink from the tap can taste different but that does not mean that it's unsafe. Water taste can be affected by temperature, the time the water has been in the pipes, river levels and flood water, and people’s plumbing systems.

Sources and consumption rates

Current sources of potable water and daily water consumption information. This page is updated daily.

Water meters encourage people to conserve water. They have led to a 25 percent reduction in water use throughout the district since installation, much like other areas of the country which have introduced them.

Ratonga | Services

We monitor water moving through each network, and receive weekly reports on the minimum night flows (MNF) for each water supply. We use these reports to identify any urgent repairs needed, and prioritise areas for targeted leak detection.

Water conservation

Water use in our homes increases in summer. For example, if you leave the sprinkler on for an hour, you’ll use 1000 litres of water.

Water education

On the Kāpiti Coast, everybody recognises that water is a resource we need to use wisely. We need to make sure that we, and future generations, have a reliable, quality water supply and have healthy streams, rivers and lakes.

Ratonga | Services

We work with our communities to ensure people in the district have reliable access to clean water, now and in the future. You’ll find information on current water projects at Projects.
