I'm guessing you'll need to support it with a lot of cross members or a floor.

Slab-on-grade design for supported tank - Foundation

May 09,2003 ground supported flat bottom tanks with a berm foundation#0183;When it comes to support an all flat-bottom tanks American Water Works Association (AWWA) D100-84 recommends that the foundation mau be designa as a:-tanks supported on ring walls (that is a concrete ring with stabilized sand inside the ring),- tanks supported in concrete slabs,- tanks within ringwalls,- tanks supported on granual berms Plastic Polyethylene Tank Installation GuidelinesAlways completely firmly support the bottom of your tank.Whenever you do not have to consider environmental factors such as wind or seismic activity,we recommend an even and compact bed of sand,fine soil or pea gravel for tanks with a base load bearing capacity of 800 lbs.or less.Missouri University of Science and Technology Scholars'tank .foundation is the major of cause of fQundation failures.D'Orazio .and .Duncan (1987) have studied data pertaining to 26 oil tanks and suggest that a differential settlement of 0.5% to 2.5% of tank diameter can be tolerated depending upon the settlement pattern of the bottom plate.Chen et.al ( I 987)

c) flat bottom without slope It can be applied in the small tanks where the removing of the water dropped inside into the tank is not required.d) flat bottom with single slope.Can be applied where the diameter D 30 m.This type of bottom requires sloped foundation and the construction of the shell must assure its vertical position.2.Experts in tank foundations and bottoms analyze designs Water pooling around the ringwall foundation They lifted tank up three to four inches.We've seen this on a brand-new foundation.The ground outside the foundation is cracked.They didn't put a compactor on the ground,so a brand-new tank is going to fail because moisture or water is underneath.You have to slope water away from foundation.Design of Steel Tanks - The ConstructorThe steel tanks are either placed on ground or placed on towers.When the steel tanks are placed on ground,then,these are supported on cement concrete foundation or on steel grillage foundation.These steel tanks with vertical cylindrical surface and flat bottom and supported on ground are known as surface tanks.
