Big Water Tanks Limited manufactures and sells high quality, potable water, Plastic Water Tanks in Auckland New Zealand. We are proud of the fact that we produce the heaviest tank with the simplest and strongest design - our 30000 litre water tank has a simple, strong dome that is self-supporting. We also use the largest "standard" shot weight of plastic, which makes our wall thickness the greatest.

Our tanks are manufactured on a custom-built, rotational moulding machine with internal temperature logging and a set point for cooking a perfect plastic water tank every time.
