Black water tanks and flush toilets for caravans.

G'day duck

It would appear that 240 fresh/110 Black would be adequate for us.

Based on my calculations we could free camp for about 7 days without filling the black water tank.

Five litres for morning use. Another 5 during the day. Let it mellow if we can't urinate in a public toilet etc during the day.

So if we allow 200 for shower etc and 80 for the toilet then we could free camp comfortably for 5/6 days.

I have checked the cost of a sytem similar to yours and was told $1200 plus black tank plus a pump to pump it out and the fittings and hose.

A vacuum system was about $4000, but used half a litre per flush.

After I finish with this thread I will have a look at jabsco.

Just as an add on to Motherhens post, I pulled up overnight on the heavy bypass road at Winton a few years ago and in the morning went for a walk past the dump point. There were around 8 RV's wanting to use the facility and there were a few nasty words being exchanged between some of the RV owners as a couple jumped the queue, while they were arguing a van owner walked up with his cassette and emptied it in around 30 seconds, he left them accessing who was going to throw the first punch, or should that have been the first bit of shite.

G'day Motherhen

Call me a sook, but I had trouble changing our childrens nappies let alone a cassette with 4 days worth of trouble. I carry the cassette to the dump point and the better half dumps it.

So, we are looking at a different system.

we would be happy to dump during the day rather than line up in the morning.

My husband never changed nappies :O. But the cassette is his job. If emptied frequently it is not a smelly job at all. If you are relying on emptying a tank with a hose, the odour will be the same, but my you will not be able access all dump point to do this. I have never used a fixed tank, but envisage that you would also need to clean the outlet hose.

1) if on the coast a lot of boat ramps & wharfs have public waste/dump points with cam/locks no smell or spills & normally a tap so you can flush the tank & hose without getting any mess on you
2) with the hose you can lift the lid on a septic as long as the chemicals your using ok with a septic & pump straight in
3) due to the extra capacity I have in the holding tank I have never had an issue dumping safely & legaly

Note: I do have a sealed hatch & area for the pump hose & the BIG/long Gloves

Cassette toilets, I have no problem with, other than they need to be emptied regularly, EG: at Birdsville last years big bash most could not cope for the duration & a lot of uses could not get them to a dump point (not strong or fit enough & could not drag the trolley) & even the rule was no pit toilets there were a lots of campers digging holes & dumping into them

Gidday John,
I have a Q4 being built. Pickup late August. Looking forward to not having to empty a cassette every couple of days and being to stay in national parks a bit longer.

Might have to train the missus on how to do the black tank though :D

Thanks John I will have a look at the site.

I have had a ball pk figure of $1200 plus the black water tank plus the pump out pump and and fittings. I will look at jabsco when I fininsh this reply.

Jares, we have the same thougfhts as you.

Thanks Jellybean

I will have a look.
