No Floor Space? No Problem.
Dewey Waters totally internally flanged tanks, (TIF) have no base to side joints or external corner joints – make this tank option 100% buildable and maintainable from the inside, unlike other internally flanged or externally flanged tanks on the market.
TIF Tank Solutions for Maximum Capacity
The below examples show the difference in tank construction of a totally internally flanged tank and a internally flanged tank.
A totally internally flanged tank is built from the inside, allowing for maximum volume.
Internally flanged tank with base & side joints does not allow for full inside construction, this increases the clearance requirements around the tank reducing the water tank volume in restricted areas.
