Water Tanks

We have over two decades of experience in manufacturing water tanks, and offer capacities from 1,350 litres to 20,000 litres that can be used for domestic, agricultural, and industrial markets, amongst others. A wide range of plastic water storage tanks up to 20,000 litres are available.

Water Tanks Information

Specialising in purely above-the-ground solutions, our plastic water storage tanks are rotationally moulded as a one-piece tank which reduces the risk of leakage through fastenings. Capacities range from 1350 to 20,000 litres. All tanks come complete with ventilation, with an access point sited on top of the water storage tank itself.

Tuffa is committed to providing the best options for every situation, whether domestic, commercial or agricultural. Our sales team is available to discuss your specific requirements with you to ensure you get the right tank for your needs.


How many types of water tanks are there?

There are 4 different types of water tanks that we provide which can be used in a variety of sectors including domestic, agricultural and industrial.


1. Standard Water Tanks
These tanks are suitable for a variety of applications and, like all of Tuffa’s tanks, range in capacity from 1,350 to 20,000 litres with the potential to increase to 200,000 litres.

2. Rainwater Harvesting Tanks
Rainwater harvesting tanks allow you to store and filter rainwater, which can be used for many purposes including irrigation and washing.

3. Waste Water Tanks
Our waste water tanks are designed for both industrial and domestic purposes meaning they can be used for storing water, household usage and for storing harmful chemicals.

4. Molasses Tanks
Tuffa’s molasses storage tanks are specifically designed to store high density liquid molasses, with ventilation to prevent the growth of bacteria and are easy to install.


What size water tank do I need?

We recommend buying the maximum capacity tank you can to reduce the chance of running out of water and to minimise the frequency of tank refills (or waste collection).

The best material for a water tank is one that is durable, corrosion resistant, and weather-proof in order to provide a long-lasting storage solution.


For this reason, all of our plastic water tanks are made from recyclable polyethylene and are manufactured to ensure a maximum wall thickness at the base – where it’s needed most. Furthermore, they are UV stabilised and require little or no maintenance.
