Plastic water tanks
Plastic or polyethylene rain water tanks are widely available and represent good value in terms of cost per litre. Polyethylene rain water tanks will expand and contract over time as they fill and release, which means they need to have a sturdy base and flexible hosing. Polyethylene water tanks are light and easy to manoeuvre into position, and have a long life if kept out of direct sunlight.
Steel water tanks
Modern steel rain water tanks are available in a range of shapes, sizes and colours and are coated with food-grade polyethylene to prevent corrosion. Steel rain water tanks are stronger than polyethylene rain water tanks and will not degrade in the sun, or bulge. In addition, they are fully recyclable at the end of their life. Neco recommends Tankworks rain water tanks.
Bladder water tanks
PVC is used as a liner for bladder rain water tanks, and underground rain water tanks. Neco recommends EcoSac bladder water tanks, as they come in a range of shapes and sizes ideal for under homes or decks.
