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.

Buy a 200-litre water tank

These rainwater tanks are a good way to store water in case of an emergency.
