OKAY for me a QP I understand that this is a 18C Tread area. But I do know there are a ton of knowledge on the site from many different people.
Just as in the Be perpared Tread, so many people have the know in making things work. IF your a farmer, cattle rancher, electrician, ETC you likely have something to add. I would like to see here what ODAs are doing or plan to and didn't work for them. Not just from 18Cs, but all 18 series. I know so many here don't like posting and just luking. POST!!

Large filters of this design can be made out of those 500 to 1500 Liter Blue water reservoir; tamdem water reservoir is the best way I feel.
One reservoir elevated above lower reservoir with Coarse sand and Gravel done in layers emptying into a Second reservoir with Coarse and Fine Sand with some type of Charcoal (Activated charcoal is best but hard to get and expensive). But you can take "cooking" charcoal (not Kingsford charcoal - chemicals!!) and hand crush it to small coarse charcoal. You make layer of Coarse sand then Fine Sand then Charcoal the repeat this process till the water reservoir is half full. As show in the BIOSAND Filter link.
You can also bring or order from UK or germany (220~240V) and
Pool Filter systems. One reservior with sand and gravel this emptys into second small reservior then the pool pump pulls from this tank to supply water to the troops. This one will eat up chlorine.
Safe water is a must anywhere. Having half or more of a element down for Dysentery realy sucks.
