Potable water Plastic 20Lt jerry Cans?

We got some from Bunnings - no problems at all with them.

Same as Motherhen. We opted for 10L with a bung/tap. Been around the block twice, still tastes like Perth water.

The light blue ones allow light to penetrate through & grow algae after a period of time. The khaki ones from places such as Aussie Disposals are much better.

At least you can see the algae Shaker. Soak in a bleach solution, shake and rinse well. Best keep all plastic out of the light anyway because it degrades and can split when you have it in the car full of water :O

No thanks, I would rather have one that didn't grow algae in the first place.

Never had a problem with algae in mine.

Are you certain there is none in yours Shaker?

Been using light blue Willow brand for over 25 years. No taste and never had Algae.

We purchased a collapsible 20 litre water canister for $5 for extra water to take camping a few years ago. We don't need it when caravanning but take it along in case we have to remove grey water from a campsite. It takes up next to no room when collapsed down. The only drawback was the tap could get bumped on a little in transit and spill. Sitting it in the large bowl we carry when camping contained any spillage.

Dion, I am at a little loss here. What was the value of achieving more space as you proceeded? What did you use the space for? And what did you do with the collapsed bladders?

Allan, I use empty wine bladders as "space fillers" as stuff is used in the fridge or storage boxes etc. Maybe that is how the empty bladders got used, but maybe not when the OP says folded flat.........

Hi Allan,
the creating of space whilst the trip is progressing, I understand your question. Perhaps it's psychological for me, gives a physical indication of a trip progressing. A bit like watching the fuel level decreasing as the trip has progressed.
What I didn't explain in my initial post, is the configuration of my utes.
Fair to say as a generalisation, most utes used to do a 4WD trip of our wonderful country are twin cabs, so lets say 80%. Of those twin cabs, then again 80% of them have a canopy, then perhaps 80% of those with canopies have a drawer system. Some people like that organisation and structure in what and how they carry their equipment and victuals for their trip. A generalisation remember.
My utes have been Rodeo's, R9, RA's and now a D-Max. All of these have been space cabs with tubs. I'm not a fan of canopies (had one on a Commodore ute once) I've always used hard lids on my 4WD utes. To have a dedicated drawer system would eat into height, as my loading within the tub can only go up to water level. Most fridges (mine are Engels) just come in for height, allowing the lid to shut. I think my loading is different to the generalised norm.
Usually when I go away, I find that both utes are absolutely full. I just find that by being able to dispose of boxed containers of water that have served their useful purpose, every morning thereafter when breaking camp, we don't have to be so anal in placing things exactly, if we have that little extra space.
As for the emptied flattened bladders, they are binned where bins are provided. Although the first couple are always retained, for 'just in case'
Another thing I like about the boxed water, just buy them and go. No need to examine every water container, flush it out, give it a sniff, give the water a taste, then filling it. Boxed water, from large department stores is always fresh.

Thanks Dion, I understand. Roz seemed to from the start. She said "It just gives you room to move"!

Hi Allan, Now our kids are grown and gone, we just take the Patrol and leave the off-road trailer home. When we head off, we are loaded to the hilt and getting to some things means removing neatly packed gear to get to them. We find it a relief when our supplies starts to thin out a little, makes packing and unpacking a little easier. We take a few square 25 liter water containers but I'm liking the cask and or bladder type idea, it would really make a difference to the space as we use it! Regards, Michael

I have 3x 40 litre poly tanks built-in to the Troopy and like Disco we experienced a taint at first. Used "Tank Cleen" product from the camping shop but didn't help much. Some may recommend "NappiSan" or the like. However, with time and water use, the taint is gone.
Between trips, I keep the tanks filled but drain and refill before each trip.

Disco's advice on filling and draining is good but I would extend the stand time to 2-4 weeks. Not to improve the treatment but to save on water and work.
