The water warning was yesterday, and there is an increasingly credible risk that Lund’s water will be unfit for use during a longer period. Therefore, we give you several tips for securing your water supply in the high-risk zone of Lund.

- BOIL YOUR WATER
This is a no-brainer – the very recommendation from VA-Syd. However, this does not make it less true. Boiling a large batch of water is key to your tolerable life within the zone.
- SOLAR WATER DISINFECTION [SODIS]
The sun is here, and if you are not satisfied with boiling your water, you can take a bottle of water of a canister to use its cleansing power on any bacteria or microbes in the water. It is enough to fill your bottle and let it stay in the sun for two hours (if the water is clear) or two days (if the water is murky).
- IMPROVISED COAL FILTERS
The sun is a fickle companion, so you can use some charcoal, sand, and cloth to create a filter which will purify your water. Put the cloth in the bottom of a suitable container with open top and bottom. Then add coal and top it with sand. This will make your water clean but murky, and you should boil it before drinking.
- BONE FILTERS
Crushed and grounded bones are excellent filters for whomever can get their hands on them. One of few methods to get rid of heavy metals and arsenic from the water. NOTE: take no lives to get your hands on the bones, you can get it from a butcher instead.
- BIKE FILTERS
Why not clean your water while riding a bike? There are many bicycle-based water filters on the market for whomever is willing to pay. Through pedalling, you drive a pump which will guide the water through a more sophisticated filter. Might possibly, with the right pump, be created at home in combination with a bone or coal filter.
- DISTILLATION
If you want to be extra thorough, boiling is not enough. Through distillation, you effectively remove anything but H and O from your water. Boil water in a container with a thin opening, put a bent pipe in the opening to collect the steam. At the top of the pipe, you can put something cooling to condense the water. Then angle the pipe so that condensed steam will drip into another container, which will now have purified water.
- EXTREME SOLUTION: HOME FILTER
Stop worrying about water and build a completely, super safe, water filter at home. A good type has the steps with the water containers. First, a collecting tank to even out uneven pressure into the system by picking up and keeping water that enters when capacity is already at max. Then, a slag container, where the water can leave behind any slag – the slag, in turn, will work as a filter for subsequent water. Finally, you should have a tank with a biofilter to clean out dangerous bacteria and other micro-organisms.
With this system, you can collect rain water, sea and river water, and even sewage, making yourself self-sufficient and prepared for a long stay in the high-risk zone. (More info at Bob’s site: http://biorealis.com/biofilter/drumbiofilter/)
