Rainwater tanks

Greater Wellington encourages the installation of rainwater tanks, including for use in an emergency, such as an earthquake.  We've compiled some information for you to consider if you are considering installing a rainwater tank at your home.

Why do we need to conserve water?

The water supply for Lower Hutt, Porirua, Upper Hutt and Wellington comes from several rivers and an aquifer (an underground water source).  These sources are dependent on regular rainfall.

During spring and summer, long periods of low rainfall can restrict the amount of water available to treat and cause water use to increase – by as much as 50%. At these times our ability to supply enough water to meet demand can be tested.

We're working to identify extra water sources, including new storage. However, if the lower level of water use seen over the last two years can be maintained, we'll get more value from our existing infrastructure for longer - saving ratepayer's money.
