DIY portable water purification system

I've got a few weeks and nothing to do, so I'd like to start on a project. The thing I've decided on is a water purification system made out of things found around the house, at Lowe's, goodwill, etc.
- I want it to be completely non-electric
- I'd like it to be either compact or easy to assemble, to make carrying it camping more feasible
- I'd like to incorporate filtration and distillation processes
- It would be great if it could desalinate as well
- The cheaper the better, I'm willing to work with anything I can get my hands on
I thought of even trying to build a manual pump to use with it, so you could place a hose in the source and simply pump in the water.
Do you guys have any ideas about this?

Hey /diy/, I'm having an issue and request your existance.
I got babbys first CMoy together a few days ago, and I stuck a logarithmic pot in there so I could control the source's voltage.
Got it all together, plugged it into a source, and can get clear, good sound coming from a pair of my cheap test earbuds. However, when i turn the pot to try to reduce the volume, nothing happens when I turn it "up" or "down".
I checked there wasn't any solder bridges on my PCB, and cleaned the flux off the back with a toothbrush and some 99% isopropanol. I still get what seems to be full volume when I turn the amp on, and plug in a source.
Please help. If you need any more information I will provide gladly.
TL;DR: My volume control on my CMoy amp is fucked and there aren't any possible shorts and the voltages/voltage drops are all as they should be. Current draw is not excessive.
