Open Top Circular Cold Water Tanks


Ferham open top circular tanks are available in two capacities: 25 and 50 gallons (114 and 227 litres).

Our circular header tanks can often provide a solution when you can’t compromise on volume and the footprint of the tank is restricted, preventing the use of a rectangular tank.

The cisterns are manufactured in accordance with BS4213:2004 using highly durable moulded plastic that is WRAS approved and can be purchased with or without the accessories kit
