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 the ability to supply enough water to meet demand can be tested.
There are loads of easy ways to use a bit less – and help make a big difference!
