A flood protection company, Supply Force, has been fielding calls from homeowners and businesses concerned about flood damage. With repeated warnings to be prepared for further flooding, many people are left scrambling, unsure of what to do.
Managing Director Duncan McNeil says “When nature is at our mercy, we can feel powerless. Yet there is a practical solution to help protect your property - floodgates. In the past, people have used sandbags to contain floodwaters. The problem with sandbags is that they are heavy, expensive, time-consuming to build, and not very effective. You can only use them once, and you have to pay to dispose of them”.
In contrast, he says “flood gates can be installed in minutes by one person, meaning you’re almost guaranteed to be able to get it set up before flooding starts. Pretty much any adult can set up a flood barrier – it’s great for people who don’t have the ability to lift heavy sandbags”.They are made from non-permeable material and pressure fitted. You simply place the gate in the doorway and inflate the seal to create a watertight barrier. Seals can be easily replaced, so you can use your gate over and over again. They are quick to set-up and pack away and they store easily in a small place.
Central Auckland experienced its wettest
month on record in January - breaking a 1869 record. With
539 mm of rain, the torrent shattered Auckland's previous
record for the wettest day which recorded 420mm. The
destruction was severe too, with over 200 homes
red-stickered, close to 700 yellow-stickered and almost 1500
white-stickered. Roads have been closed, homes destroyed,
and, most devastating of all, four lives have been lost due
to the atmospheric river. But is this really a once in 200
year event? Do we have to prepare for it to happen again?
Check out this article written by Marc Daalder, he
summarises the Auckland
flooding in five charts. He explains how temperature
affects extreme weather events: “the atmosphere holds 7
percent more water for every degree it warms. We're at 1.1C
of warming already” says Daalder. In a chart provided by
NIWA, you can see how Auckland’s annual average air
temperature has risen from 14.9C in 1963 to 16.9C in 2022.
Floodgates may well become an essential part of our lives in
the near future, as they provide fast and easy
protection.
