Moulds that have radius floor wall

Our moulds have a radius floor wall that’s similar to most in-ground pools. It produces more than twice the structural strength as opposed to most if not all tanks of this size

Inbuilt riser for underground applications

Inbuilt riser for underground applications

Next Gen underground concrete water tanks have an inbuilt riser for underground applications. It can be made to suit any depth, and fittings can be moulded instead of using a drill or jackhammer. This can also eliminate the chance of dirty ground water seeping in and contaminating your fresh storage water.

Benefits of a Next Gen’s Concrete Water Tank

Concrete tanks can have a very long life of 100 years plus.

Highly fire-resistant and even fire-proof if installed underground. Also, concrete is a better insulator than steel or plastic. It will help keep the water cool ensuring that your water supply is algae-free.

Almost zero maintenance. A shovel and pressure washer can be used to clean a concrete tank without worrying about piercing a liner.

A concrete underground water tank can be fully emptied and left empty, unlike other water storage systems that aren’t designed for this condition as it can void the warranty and leave it susceptible to wind damage.

Concrete rainwater tanks are extremely unlikely to be damaged by root intrusion, vegetation growth (falling tree branches), livestock, vermin, or extreme weather conditions.

Our tanks with the gutters stop water runoff down the side of the tank, preventing damage to the base underneath or the surrounding earth.

Next Gen did great especially with a muddy site and the weather it was interesting to see how a tank is build and the gutter in particular. Would highly recommend!
