1.Underground tanks starting from the small, compact 1,100 litres which is ideal for a small Storm Water Retention Tank etc, up to 4,500 litres, 5,500 litres, 7,500 litres and the 10,000 litres tanks. Our unique design shows them as being a tough tank that will stand the test of time and what ever nature dishes out. Our underground water tanks have large ribs that add to the overall strength that many other tank companies lack.

2.Underground water tanks manufactured by Shanghai chunxu are one of the very few underground tanks that have actually tested and comply with the Australian Standards. One of the extreme tests require that an empty tank be fully submerged in water and not fracture making sure that the tank can meet worst case scenarios. Our tanks are made of  high quality virgin polyethylene which also meets the Australian Standards for contact with food and water.
