Our water supply network crosses fault-lines in multiple places. We expect it to take more than 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.

You need to ensure you’re prepared for the challenges to come. You’ll be relying on the food and water you have stored at home.

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 wastewater?

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

What do I need to do following an earthquake?

Store drinking water

You need to have stored water for you and your family for at least seven days. This water will be used in a range of ways. The more you store the more you can do with it.

We recommend that you store 20 litres per person per day - if you have a family of four, that's 560 litres. You may need to store more if you have unwell people or small children in your family.

Things to consider

You may have extra sources of water in your house - your hot water cylinder is a good source. Water from swimming pools or spa pools aren't suitable for drinking but can be used for cleaning and sanitation.

You may have extra people in your house after a natural disaster as they could be evacuated from their homes. You'll need extra water to support them. Or you yourself may have to move to a friends place (particularly if you live in tsunami zone or in an apartment with limited water storage) - do they have enough water for you as well?
