Best Caravan Grey Water Tanks in Australia

Are you looking for a new grey water tank?

This isn’t the most glamorous caravan accessory, but it’s a very useful one. If you plan on travelling to Australian National Parks, then a grey water tank may actually be a legal necessity.

It’s not mandatory to have a caravan grey water tank at regular campsites, but it’s advisable. Environmentally responsible campers dispose of their grey water in a considerate manner - rather than just dumping it on the ground.

But where do you start? There are so many products on the market it can be confusing.

Let’s look at a variety of greywater tanks for caravans from different manufacturers and break them down to figure out the best option for you.

Best Caravan Grey Water Tanks

50L Universal Water / Grey Water Tank

50L Universal Water Grey Water Tank

Best Value

Pros
  • Cheap
  • Lightweight
  • High-density polyethylene
  • One-year warranty
Cons
  • Small size
  • Manual modifications required
  • May swell when full

One of the most affordable portable grey water tanks for caravans, the Universal costs between $50 and $90, with a one-year warranty.

This caravan water tank comes in at 50L which makes it suitable for most camping vehicles. If you’re planning on spending a lot of time on a pitch, this may be the right size for you.

The tank’s smaller size also means lighter weight. It weighs just 2.5kg which is great news for your caravan’s payload.

It’s also a very durable tank and designed not to fail. The manufacturers blow mould it from food-grade high-density polyethylene.

However, this caravan grey water tank presents several potential issues.

Firstly, the size won’t suit everybody. If you’re planning on spending a lot of time off the grid and away from suitable dump points, a bigger tank may be required. The same applies if you have several people in the vehicle.

You will need to drill a 3-4mm hole in the top of the tank to allow for air venting. This may be irritating for those who prefer to avoid DIY and want a more plug-and-play type solution.

Another problem is that this greywater tank may swell when full. It will fill relatively quickly so this is important to keep an eye on.

70L Fiamma Water Tank

70L Fiamma Water Tank

Honourable Mention

Pros
  • Ideal capacity for most purposes
  • Lightweight
  • Can be used horizontally or vertically
  • Non-toxic plastic
  • One-year warranty
Cons
  • More expensive than competitors

Fiamma is a brand leader in the world of caravan appliances.

Most caravan enthusiasts will be familiar with this Italian manufacturer. Their caravan grey water tanks aren’t cheap but they are well made and come with a one-year warranty.

Like the smaller Universal tank, Fianma makes it from non-toxic plastic. However, it holds an extra 20L so you won’t have to empty it as often.

It comes with all of the fittings for installation. This includes clamps, so it can be easily mounted on walls or floors. Meanwhile, you can place it horizontally or vertically for greater flexibility.

This caravan grey water tank weighs less than 5kg so it’s not heavy at all.

However, the $179 price point may put off a lot of potential customers because it’s possible to buy bigger tanks at a cheaper cost.

95L Camec Grey Water Tank with Fittings

95L Camec Grey Water Tank with Fittings

Honourable Mention

Pros
  • Large capacity
  • Excellent value
  • Offset flush point for easy flushing
  • Allows for multiple tanks to run inline
  • One-year warranty
Cons
  • Size and weight won’t suit all users

If you’re looking for a larger grey water tank, this 95L Camec could be the right size. With its large capacity, it’s excellent for motorhomes and campervans. However, it may not be suitable for some caravans.

Firstly, it is excellent value considering the dimensions. It costs around $120 which makes it a lot cheaper than the larger Camec below. If you don’t have weight and space restrictions then this is a more sensible option.

It’s easy to connect sinks and showers directly to this caravan grey water tank.

However, it is slightly on the chunky side. With a width of 220mm, it’s wider than some tanks with a larger capacity.

If you find yourself in a tough situation, this Camec can even double as a large storage tank for toilet waste.

Like the other tanks on this list, it comes with a one-year warranty.

110L Camec Grey Water Tank with Fittings and Bracket

110L Camec Grey Water Tank with Fittings and Bracket

Our Pick

Pros
  • Large 110L capacity
  • Comes with fittings and bracket
  • Can be used as a fresh or grey water tank
  • Easy installation
  • One-year warranty
Cons
  • Won’t suit smaller camping vehicles

At 110L, this Camec is one of the largest portable grey water tanks for caravans.

Once again, this won’t suit smaller vehicles because of its size. It’s 7kg when empty, so this is also something to keep in mind.

One of the main selling points of this tank is that it’s universal. It’s made from food-grade plastic so you can also store freshwater inside.

It comes with all necessary fittings and a bracket so it can easily be installed. This tank also has a one-year warranty.

Camec is also an Australian brand based in Melbourne with a rich history in the industry. In short, they’re very reliable.

Size Matters

Typically, the size of your grey water tank should be equivalent to your freshwater tank. However, this can cause weight issues if you don’t manage it correctly. Avoid driving with both tanks full at the same time.

Water weighs 1kg per litre. Bear in mind that most single-axle vans can carry a limited payload of 300kg. Double-axle vans usually have an allowance of 400kg.

If you have a single-axle van with a 110L Camec, you’re probably going to have just 80kg left over. It’s just not going to work. Use common sense and get a grey water tank that fits your van’s specifications.

However, you should also think about your requirements. If you’re going off the grid, you’re less likely to have regular access to grey water disposal points. A larger tank may be better in this scenario.

Final Thoughts

Greywater tanks are useful for storing your kitchen, shower and washing machine wastewater until you reach a point where it can be safely dumped (ie. everything bar the waste from your caravan toilet).

They are an integral part of the water system in your caravan and are quickly becoming a necessity - especially for those who like to free camp.

Bear in mind that weight is the main point of consideration when you buy one.

If you’re not worried about your payload, then the Camec 110L caravan grey water tank makes a lot of sense. It’s the biggest and it represents excellent value compared to some of its competitors.

The 50L Universal tank will suit most people’s needs. This portable greywater tank for caravans is also of great value.
