One of the biggest needs people have during natural disasters is drinkable water. Hurricanes often cause flooding that can isolate people and make them unable to obtain supplies. They are stuck in areas with a lot of water where none of it is drinkable when lakes or other freshwater sources overflow and get mixed with dirt. If you live in a high-risk area for flooding and want to be prepared or help others be prepared, you now have a number of interesting solutions.
Portable Squeezing Filters
When a disaster happens, one thing that's often up in the air is how long you're going to stay in one particular spot. You may be trapped in your house, for example, but you have to suddenly move to higher ground when more flooding happens. In these cases, it helps to have a light and portable device that works in a very simple way, such as by simply squeezing it.
There are options like this currently available. Some of them can filter up to 99.9 percent of diseases that live in water, which is something you have to worry about in disasters. These systems are also often reusable and can filter as much as 100,000 gallons before you need a new one, depending on the model. Many also weigh only ounces, making them effective for a changing situation.
While the actual day of a flood is traumatic all by itself, it's often the days, weeks, or even months after that can be the real problem if you're trapped and the water isn't receding. An effective way to detoxify water over the long term is with sunlight. Ideally you would have a commercial system to do this since this would be the most efficient, but this isn't necessary.
In a pinch, you can also use sunlight to kill germs from water using a few items around the house. This works best if you're more worried about germs than you are with other contaminants. Perhaps you have a non-germ filtration system, for example. You can clean a "PET" bottle with "recycle code 1" on the side of the bottle to start.
Then, you put the water out in the sun. Ideally you should lay the bottle on its side so that it can get as much UV as possible. If you have something shiny and reflective like tinfoil this can also increase the effect. It should only take 6 hours if it's mostly a sunny day; otherwise it will take as long as an entire day or more.
Overall, it's important to combine chemical filtration with germ filtration to get completely pure water during disasters. Your other filtration methods should specify whether they get rid of metals and other contaminants. For more information about filtration options, visit Holmes Ecowater.
