Just some of the places using our concrete tanks


Above Ground Tanks

We design, manufacture and install a wide range of above ground concrete tanks. Ideal for a range of purposes and built to last. Existing sizes or we can make something bespoke for you, just let us know what you need it for.


Underground Water Tanks

Underground tanks are manufactured with a strengthened flat roof and a central column to support the roof. They are designed to be covered with dirt to maximum depth of 300mm. An underground concrete tank costs more than an above ground concrete tank.

Stormwater Tanks

Our range of larger built on site tanks are regularly specified by engineers and civil contractors for stormwater retention/detention. We also manufacture a range of precast transportable stormwater tanks that are also suitable for stormwater re-use or rain harvesting tanks.

Ross Tanks can also manufacture one off design and builds to meet customer requirements (maximum capacity 100m3) i.e open top tanks.

All tanks are circular. Heights (height to the top of the wall) can be changed if necessary, although diameters are fixed.
