i learned this camping foe years. get any size water bottle, depending on if its a jug, a couple drops, or jus a regular water bottle, jus a drop. but get a drop of bleach, put it in the water an let it sit for 15 or 20 min. when its done, you put the water bottle or jug upside down an barely open the top/lid , to let all the dirty water drain it self from the lid. so by doing this all the dirty water will, sink an havin the lid barely open like when you barely close a water bottle or sum, it will jus drip out all the dirty water. 🤞🏽

I have a guy i work with who was doing that in the army ill pick his brain monday when i go to work
