A big thanks to all our customers who came to our stand at Fieldays 2019 - we had a very successful show, selling many tanks and accessories.

Big Water Tanks offers a full range of Hansen Products including Easy Fit pipe fittings, True Fit threaded fittings, tanks level indicators, tank plugs and a variety of high-flow valves.

There are a number of factors that influence the amount of water that animals drink, such as lactation, temperature and the age of the animal.

A plastic water tank is the most cost-effective, easy-to-move and reliable water storage solution for potable water. We specialise in manufacturing 30,000-litre water tanks, which are made using high-grade Polyethylene plastic.


Our plastic water tanks are strong, heavy-duty and reliable. We manufacture our tanks with the heaviest shot weights and the most plastic to give the strongest wall thickness. Our big 30k water tanks can be buried up to 700mm in the ground and retain its full 20 year warranty.
