Have you thought about what you’d do for water after a major earthquake if the water network isn’t working? And do you have a plan for what to do with your ones and twos?

The single best thing that people can do to help Wellington survive and thrive after a major earthquake is be prepared.

Wellington Water and our Councils are working to make our infrastructure stronger every day. A number of initiatives are underway, including looking for temporary emergency water sources in Wellington and Porirua, testing water bladders to see if they can be used to distribute water and looking for drinking water under the Wellington Harbour.

Water tanks 

WREMO has partnered with a New Zealand water tank manufacturer, The Tank Guy, to make a 200 litre water tank and kit available for $105.

Drinking water

Our water supply network crosses fault lines in multiple places. We expect it to take up to 100 days to restore services in some suburbs in the Wellington region.

Following a major earthquake, the first thing people rely on is themselves and their families - so storing water is a must for every household.

The wastewater network is even more vulnerable than the drinking water network - its broken pipes would take even longer to find and fix, and there'd be more of them.

Have you got a plan for what to do with your ones and twos

Wastewater isn't just about toilets - you'll also need to think about how you would dispose of water used for cooking and hygiene. Water from cooking can be tipped into gardens, but keep water used in washing clothes or yourself away from food producing gardens.
