Our range of Non-Potable Water Storage Tanks are mainly used for commercial applications such as agricultural irrigation, toilet flushing in industrial or commercial premises, horticultural and gardening applications, and civil engineering situations where mains water is not available. The Tank Shops range of Non-Potable Water Storage Tanks are suitable for any application where the water or liquid stored will not be consumed by humans or animals. Most plastic water tanks manufactured are non-potable or unsafe for collecting water for drinking purposes because they have a porous surface that can collect bacteria that will defect the water in the tank. Our Range of Non-Potable Water Storage Tanks start at 100 litres and go up to 25,000 litres in one tank.
