The ProTank module system is very versatile and can be utilised for leech drains (from a septic tank), soak wells (for stormwater management) or as an underground tank.

Features and Benefits

Strong structural design – can be installed under driveways, carparks and other trafficable areas, therefore, increasing the use of valuable land.
Infiltration – a large permeable area including sides and ends.
Detention – Alleviates onsite/downstream flooding.
Retention – Can be used as a retention tank so that it is easy to collect, store and reuse precious rainwater.
Larger volumes with fewer modules – projects require fewer modules resulting in less assembly time.
Chemically inert – the units will not be affected by harmful chemicals, therefore increasing the product life.
90mm and 150mm Cut Out Guides for DWV – Allows for simple pipe connection therefore less time is taken for installation.
UV Stabilised – for increased product life.
100% Recycled Polypropolene – Environmentally friendly.
Modular – The units interlock vertically and position horizontally to create any size and shape required.
Lightweight – easy to handle. No crane is required.
Flat Pack Form – Easy to transport and save on bulky transport expenses.
Manufactured in Australia.
