Custom water tanks for camping and caravanning

CV Plastics can supply water tanks to fit your caravan or camper trailer. Most caravan parks now require grey water tanks be installed in caravans before they can park. Camping trailers may be packed to the hilt but you've found some wasted space just in front of the axle, perfect for a drinking water tank.

CV Plastics can tailor a high density polyethylene water tank to fit in to the smallest of places out of sight and out of mind - until you need it.

Custom water tanks at home

CV Plastics custom fabricated water tanks are suitable for hiding in the garden, the back of the shed or even under the decking to store your rain water or waste water from the shower, washing machine and the like.

Custom water tanks at work

CV Plastics can supply your water tanks for custom fitting to your work vehicle, ute, trailer or b. Where ever you need to store water or chemicals, we can build a tank to fit.


We can supply installation guidelines, or we can fit your water tank for you.
