Resilience - drinking water and wastewater

Jump to the related documents

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

Wellington is more vulnerable to earthquakes than other major metropolitan areas. 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.

You need to have to stored water for you and your family for at least seven days.

We recommend that you store 20 litres a day per person for seven days. A 200 litre tank would be about right for two people – or two of those for a family of four.

There are ways to store water for people that live in flats or apartment buildings - large bottles or smaller tanks, for example - that can be stored inside.

There are a number of community water storage tanks dotted around the Wellington Region. Check out the pdf at the bottom of the page.

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.

Households should also be prepared for what to do with wastewater as well. Digging a latrine, using plastic bags for human waste, or chemical toilets are some options.

The Wellington region is one economy. After a shock, we’ll need to get back to work quickly to keep our place going, and our Councils are working to make our infrastructure stronger every day.
