DIRTY WATER COLLECTION BLADDER VS. CLEAN BOTTLE ROUTING
[ ] 3L Dirty Canteen
[ ] Wide-Mouth Clean Jug
[ ] Inline Quick-Disconnects

3L Dirty Canteen: the owner's number. Choose a size you can carry full from the source.
Wide-Mouth Clean Jug: easy to fill and easy to clean. Check it is food-safe.
Inline Quick-Disconnects: fittings that connect hoses and bottles. Check compatibility with your filter and test for leaks.

Name the sides. Say "dirty" and "clean" out loud when you handle them. Why it matters: cross-contamination can undo all your filtering.
Keep the clean end clean. Cap the clean jug and the filter outlet when not in use. Clean your hands before touching either.
Camp away from water. Follow Leave No Trace guidance for distance from water and for washing. See lnt.org and your park website for current rules.

Gear types only.

Water access, camping distance from water and washing rules vary by park, forest or area. Check current local rules before you go. Start with nps.gov, fs.usda.gov, blm.gov or your state park site, and for water treatment guidance, cdc.gov and epa.gov.

Two paths, never crossed. Dirty in, clean out. Built by explorers, for the trail.

Two sides, two colors

3L Dirty Canteen, marked as the dirty side
Wide-Mouth Clean Jug, marked as the clean side
Use different colors or labels so you never mix them up in the dark
Pack them in different parts of your bag

The route

Inline Quick-Disconnects fitted between the canteen, the filter and the jug
Check that fittings click and seal before the first use
Spare O-rings or gaskets packed
Keep the filter outlet end clean and covered

At camp

Fill the dirty canteen at the source, well away from camp
Filter or treat as your plan says, into the clean jug
Keep the clean jug capped, and set it on a clean surface
Wash hands away from the water source

Cleaning

Rinse the dirty canteen with clean water after each trip
Dry everything with the lids open
Never store the clean jug with the dirty one

Mistakes to catch

Do not drink from the dirty side
Do not dip the clean jug into the source
Do not set the filter outlet on the ground
