How much to carry, what to carry it in, and how to keep a supply at camp or the cabin clean.
What you need
- Two hard bottles, one litre each, wide mouth
- A soft bladder or collapsible jug for camp
- A marker or tape to tell raw water from treated
- Clean food grade jugs with caps for the cabin
- An insulated sleeve or a spare wool sock for winter
How
- Plan on about three to four litres a day moving on a mild day, more in heat or hard work. Cold weather dries you out just as fast; you only notice it less.
- Know where the next water is before you leave the last. On the map, a brook you can see is water; a dashed blue line may be dry.
- Keep raw and treated water apart. Mark one bottle or one jug RAW and never drink from it.
- Fill the raw container, treat into the clean one, and keep dirty hands and the raw mouth away from the clean threads.
- At camp, hang or shade the jug. Sun warms water and warm water grows things.
- At the cabin, store in clean food grade jugs, dated, in a cool dark place. Change it every six months.
- In winter, carry bottles upside down in an insulated sleeve. Ice forms at the top first, so the cap end stays clear.
- At night in winter, put a bottle of warm water in the sleeping bag. It keeps you warm and it will not freeze.
Do and don't
Do
- Drink before you are thirsty. Pale urine is the check.
- Keep enough at the cabin for emergencies: at least two litres a person a day for drinking, more for cooking and washing.
- Wash storage jugs with a little household bleach and rinse well before refilling.
Don't
- Do not reuse jugs that held milk, juice or chemicals for storage. Milk jugs break down and never come fully clean.
- Do not let the raw bottle drip onto the clean one while you pour.
- Do not ration water you already have when you are thirsty. Drink it and find more.
Watch for
Danger
- A bladder hose freezes solid in minutes below zero. Blow the water back into the bag after every sip or carry bottles.
- Dark urine, headache and cramps mean you are already behind. Stop, drink and rest.
- Stored water that smells or has anything growing in it gets dumped, not treated.
Notes
Water is heavy: a litre is a kilo. The trick is not to carry all of it, but to know where the next fill is and to arrive with a little left.
On a winter trip, the stove is the water source. Budget fuel for melting snow before anything else.
