Tank sizes
The tanks have volumes between 30 and 5,000 m³ (7.935 and 1,323 gal) and can be constructed as high and narrow or low and wide as required.
The Börger stainless steel tanks can be extended so that additional segment rings can be installed at a later date to increase the volume of the tank.
