2. Self containment done for you


We have to replace and re-route most of the waste water pipes under the van, fitting waste traps etc.

Price does NOT include a rollaway container, we modify yours.


The NZMCA work tirelessly for the benefit of caravan and motor home owners, there are many member benefits available which even without trying often amount to more than the annual subscription, plus a fantastic travel directory listing amongst all the regular DOC and campgrounds  many  ‘secret’ spots kindly shared by other members and a bi monthly magazine.

Self containment goes a long way to keeping NZ clean and green the association fights strongly to ensure councils allow certified self contained caravans to park in freedom camping spots that are not available to none certified vehicles.

We are qualified self containment officers so can do the conversion on your caravan and get it certified self contained for you.

What it involves on your caravan.
We have to replace and re-route most of the waste water pipes under the van, fitting waste traps and observing the diameters and max run a pipe can be.
We take these pipes to a point on the off side of the caravan and route them into a closable ball valve. Next we modify your roll away wast tank with breathers and close off ball valves (see pic) the tank then connects to the caravan via a flexible hose.


Doing it this way means we can usually SC the van for 4 people, any more than that and you need to take additional water capacity.

We generally don’t install permanent gray water tanks for a number of reasons.
1. When you pitch up you will often have an awning up and it then doesn’t make it very easy to take your caravan to the dump station to empty the tank.
2. It is not easy to empty the tank on your pitch as the tank outlet is close to the ground so getting the water to run into a suitable container is not easy – i know this from experience…..
3. Caravans have a carrying capacity of around 250kg which is usually taken up with all the things you load into the caravan so having a full say 100L water tank (Fresh or waste) is more than likely going to overload your max load rating


the cost is $500
This doesn’t include membership of the association you can join here.

The price DOES NOT include us supplying a rollaway waste container, we modify YOUR rollaway waste container.


HOWEVER having said all the above, I have a smaller 50-70L fitted under my van, it is great for traveling as you don’t need to worry about connecting waste water if you stop for lunch or a quick over nighter.

We can quote you for fitting an on board waste tank
