The Under Deck Poly Tanks from Waterplex have an advantage over other types of water tanks as these can easily hide away under your deck and out of sight while also providing you with a reliable method of rainwater storage. Engineered from food-grade plastic to meet the Australian water tank standard AS4766, the tanks are also made from durable UV stabilised plastic so that you do not have to worry about plastic breakdown. The Under Deck Poly Tanks are available in three different heights in order to allow you to fully maximise your water storage in the space available under your deck. These tanks can hold from 1,800 litres to 2,000 litres of water. Multiple tanks can be linked together to increase capacity, and they do not even have to be side by side.
