Dunn & Watson currently provide a range of grey water tanks ranging from 65L, 80L and 100L. They are actually coloured grey to distinguish them from our black water 4WD water tanks and our yellow diesel tanks. Our Australian made grey water tanks are perfect for caravans, camper trailers and RV motorhomes. They are designed with tough 8mm thick walls, so you don’t need any straps or basher plates to prevent punctures on the road.
The outlet and inlet pipes come with a wider bore than the potable water tanks to better suit your needs on the road (1 ¼ inch fittings). Installation is easy because all you need to do is bolt the tank to the underside of your vehicle using the pre-drilled holes.
Installing a grey water tank in your caravan, camper trailer or RV is good for the environment as the tank collects all the domestic wastewater (except from the toilet). This includes wastewater from the kitchen and bathroom sinks, showers and washing machine. Many Australian campsites require RVs and caravans to store their grey water and dispose of it in specially built dump sites, whilst others are happy for it to drain into the ground. It’s best to ask about these rules regarding disposal of grey water at the site office.
