What is a caravan grey water tank used for?

A caravan grey water tank collects waste water from sinks, showers, and washing machines. This water is then disposed of via a hose into a designated drain. Grey water doesn’t include toilet waste; that’s called black water and needs a separate tank. If you're wondering, urine from the occasional shower wee should be avoided. Not all caravans come with grey water tanks, so you might need to install one yourself. Do you need a grey water tank in your caravan?

Many national parks and state governments require your vehicle to be fully self-contained. This means no grey water from your van can go onto the grass or bush. You'll need a grey water tank fitted to your caravan or a portable water tank on board. Besides meeting these requirements, a grey water tank is convenient. It collects water so you don't have to worry about where it drains. You can easily empty it at a drop-off point. A caravan waste water tank is perfect for those ready to hit the road anytime. Check out our range online to find the right solution for your caravan, RV, or camper.

How long can you keep grey water before you need to empty it?

You should empty your grey water tank every few days. If you leave grey water too long, it can start to smell and attract bacteria. Some people empty their tanks daily to avoid any issues. It also depends on the tank's capacity and how much water you use.

Do you need to clean grey water tanks?

Yes, it's important to clean your grey water tank regularly. Cleaning helps prevent bad smells and keeps your tank in good working order. Clean your water tank using Tank Cleanse from Coast to Coast or the Tank Cleaner from Thetford.

Can I use a grey water tank as a fresh water tank?

No, a grey water tank shouldn’t be used as a fresh water tank. Grey water tanks are designed for waste water and can have bacteria or leftover residue. Fresh water tanks are made for clean water only. Mixing the two can lead to health risks. It's important to keep your water sources separate to ensure safe and clean water for your caravan or RV.
