Drinking Water, Wastewater, and Stormwater Services

From 1 July 2026, a new water organisation called Tiaki Wai Limited will look after the drinking water, wastewater, and reticulated stormwater services on behalf of the five councils within the Wellington metropolitan area.

These services includes managing any maintenance, repairs, and improvements required across the three water networks.

Water Restriction Levels

Did you know that Wellington faces limitations in its daily water supply? During winter, when rainfall is abundant and river levels are healthy, we can provide approximately 220 million liters of water per day. However, in the hot and dry summer months, river levels decrease, causing our daily supply to diminish to around 170 million liters.

Water conservation

We all have a part to play in conserving water, especially in the garden and during the hot summer months.

Our city is currently facing water restrictions. This means that we need to manage water usage, here’s a brochure on quick water saving tips and how to store emergency water.
