Aplast CARAVAN waste water tank 70 l - 70 x 40 x 30 cm, polyethylene, for campervans and caravans
- Aplast CARAVAN grey water tank with a capacity of 70 l and dimensions of 700 x 400 x 300 mm. It collects water from the kitchen, washbasin and shower in a campervan or caravan. It is made of polyethylene by seamless rotational moulding.
The Aplast CARAVAN 70 l is a grey water tank for campervans, caravans and other recreational vehicles. It collects water from the kitchen, washbasin and shower and holds it until you empty it at a disposal point. The tank is a rectangular block measuring 700 x 400 x 300 mm with a central inspection lid on the top. The Slovenian manufacturer Aplast makes it from polyethylene by rotational moulding, so the body is a single piece with no welds or bonded joints. The CARAVAN range also includes smaller and larger tanks of the same design, which makes it easy to match the capacity to the space you have in your vehicle.

What it is for
A grey water tank collects used water from the vehicle installation and stores it until it is emptied. The manufacturer describes the CARAVAN range as tanks for the collection and temporary storage of grey water and wastewater from the kitchen, washbasin and shower of recreational vehicles. It is not a drinking water tank and not a toilet waste tank. If you need a fresh water tank of the same size, choose the drinking water model from the CARAVAN range.
Dimensions and installation space
- length (A): 700 mm
- width (B): 400 mm
- height (C): 300 mm
- central lid (D): 200 mm
- Before you buy, measure the space in the vehicle and allow room for fittings, hoses and mounting.
- Plan the installation so that the inspection lid stays accessible, as this is how you look inside and clean the tank.
Connections and installation
The tank has a one-piece body with an inspection lid. The manufacturer catalogue does not list inlet, outlet or vent fittings as included, so plan the connections for your own installation: inlet from the traps, drain valve and vent. Use fittings designed for polyethylene tanks. Secure the tank so that it cannot move while driving and the full weight of the water rests on supports or straps.
Material and construction
In rotational moulding, molten plastic is spread evenly over the walls of a rotating mould. The result is a one-piece tank with no welds that could start to leak. Polyethylene does not corrode and copes well with vibration on the road, which is why the manufacturer uses it for vehicle tanks. Aplast works to ISO 9001 and ISO 14001 management systems.
Use and cleaning
- Empty the tank regularly at designated disposal points.
- After emptying, rinse it with clean water to reduce deposits and odours.
- During servicing, check the condition of the lid and its gasket.
- Before winter storage, drain the water so that it cannot freeze in the tank and hoses.
