You’ve discovered that you require a new house sewerage treatment solution. You have done a bit of research and you have quotes for sewerage treatment options with both plastic (poly) and concrete tanks - but you don’t know which is better and whether their use cases are different… 

So what exactly are the differences between plastic and concrete tanks?

Plastic Tank benefits: 

1. Plastic tanks are lightweight and easily manoeuvred. They can easily be moved around with a digger, which makes them perfect for installation on sloping blocks and blocks where there is limited access for trucks, cranes and machinery. Furthermore, as less machinery is involved, their installation, in this situation, is generally cheaper.

2. Plastic tanks don’t break down or get eaten away in acidic environments like concrete tanks do.

3. In highly reactive clay soil, prone to significant expansion and contraction, plastic tanks give and take, where concrete tanks will often crack.

4. When installing a concrete tank the join at the top of the tank needs to sit above the ground, plastic tanks don’t have this same requirement which means they are able to be more discretely integrated into your yard.

5. It might seem a little silly to note this, when our last point was that plastic tanks could be virtually hidden completely underground, however, for the small component that is left above ground, a plastic tank has the flexibility to be made in any colour (we like the green the most). By allowing colour flexibility it means that your tank is able to easily camouflage into its surroundings ensuring you can maintain the aesthetic of your yard. 

6. Plastic tanks don’t require as much maintenance as concrete tanks. You can pretty much install them, and just undertake the regular maintenance that you would require on your sewerage treatment plant (whether it were plastic or concrete).

7. Plastic tanks come with moulded feet at the bottom which assist to anchor the tank into the ground.

Concrete Tank benefits: 

1. Concrete tanks can be backfilled around with any material, large rocks etc are not going to dent the side of the tank.

2. Concrete tanks can have risers added if the top of the tank needs to be lifted or depth needs to be increased

3. Concrete tanks can often be marginally cheaper

So now we have summed up the benefits of each, which tank would the HC Plumbing team recommend? 

As with all of our recommendations, we would prefer to undertake an obligation free assessment to provide you with specific advice for your needs (call 0439 648 390 to book your free assessment now), but if we had to provide general advice we would say…

In most instances within the Toowoomba and Darling Downs regions, plastic tanks offer a better alternative because they: 

• Cope better with the highly reactive soil in the region
• Are logistically much easier to install
• Repairs can be made to tank if ever required
• Are aesthetically the best choice as they can more easily be camouflaged into your yard
