Water and Travel

[Wulf202]

Not a ton of space. It must fit in one section of a backpack. I can spend a good amount of money on this. Thanks!

Personally I would bring a solar or crank steripen ~$100
A sawyer squeeze ~$40
fill the remaining space with some coffee filters for the prefiltering of the steripen and katadyn tabs to use with the sawyer.
If you have the inkling that you may be there longer than these would last I would ad a w.a.p.i. to your ditch kit. It's explained in the thread I linked.

In those area's you really need to double treat your water.

The primary setup. Your dirty water would go into the sawyer bags, drop your katadyn tabs into the bag. Wait the time for the tabs then use the filter to drink or transfer to a clean container. This should taste decent but acquire some flavor powders with electrolyte to keep you hydrated. Pre filtration will make the filter last longer.

The backup is a steripen, fill your cup or bottle with dirty water thru a pre filter to get the turbidity out. You're using light so you don't want particles casting shadows inside the water. If you're getting cow runoff, it will still taste like cow run off it's just safe to drink cow run off. If you run out of tabs you can use the steripen with the filter. Read and comprehend the directions to use this tool you can accidentally recontaminate your supply if you don't do it right.

Tertiary is WAPI, it's about the size of a cheap string level. It requires alot of energy and time to heat water unless you have a stove and ample fuel. Boiling is not necessary and adds to the time and energy you need to spend elsewhere.

Last resort is SODIS outlined in the sheet using scrounged containers.
