Drinking water on treks

If you can , the bladder style are pretty damn good. Fit in the footwell of the rear seat . . . some fit into the rear quarter panels . . .

Not real cheap . . . ARB have them.

2. You cans always boil the water . . .

Depends on how much you want to carry (time away, number of people), how much room you have, how much you want to pay etc. Bladders can carry heaps. Do a search on internet and you'll find heaps of suppliers. All (most) 4WD stores like ARB & TJM etc should have them. Not exactly cheap (when compared to plastic containers). Another possibility is a caravan type water tank.
Due to legal issues I imagine every "campsite" these days would be telling you if the water isn't suitable for drinking. If you're picking up water from an unknown source Puritabs work (but don't taste particularly nice). Go to a camping store - they'll have them. Must be used at the specified rate to be any good. There are others but I've never used them.

Sandie, we have used a bladder from OPP Lock for several years ,holds about 55 ltrs & lays on the floor behind front seats. If you top up in the bush would recommend the pills camping shops sell. Wash out the bladder with a bleach mix & then rinse with a bi carb mix from memory instructions were included. We also carry a couple of those 10ltr casks of filtered water. When we take the camper all up we have 250 ltrs of water ( Lex likes her shower ) & if she's happy makes my life easier.Regards Bob
Where to next

I prefer water in multiple containers - you can separate good water from dodgy water, and were you to get a leak, you don't lose the lot.

ny collapsibble /flexible bladders from these guys , cant remeber the prices but were better than ARB listed prices and more variety.
gaurenteed taste free.

hope it helps

dont ask me how i found him.
oops sprung!!

Might I suggest contacting Whitworths Marine - : www.whitworthsmarine.com.au
They have a mail order catalogue which you can request and mine is sent to me regularly with updates. They have a massive array of gear mostly used for boats but a huge amount of the gear is also suitable for around the 4x4, trailers, caravans etc. and I find their prices heaps cheaper than most of the 4x4 accessory stores. The flexible water tanks they supply are double skinned and suitable for laying on the deck of a boat in the salt and sun, the 100 lt tank price is $119.oo. Thats a lot of water so you don't have to fill them full and could lay them in the back, remember to order some hose and caps for the filler and outlet. They also supply water purifiers, in line pump filters, the list is endless.
No I don't work for them, just giving you blokes the good oil. Worth a look.Carpe Diem
