• REVIEW
• TYPES OF TANKS
• DESIGN OF CIRCULAR WATER TANK
RESTING ON GROUND WITH
FLEXIBLE BASE
• DESIGN OF CIRCULAR WATER TANK
RESTING ON GROUND WITH RIGID
BASE

• INTRODUCTION
12
• Storage tanks are built for storing water, liquid
petroleum, petroleum products and similar liquids
• Designed as crack free structures to eliminate
any leakage
• Permeability of concrete is directly proportional
to water cement ratio.
• Cement content ranging from 330 Kg/m3 to 530
Kg/m3 is recommended in order to keep shrinkage
low.

• The tank has tendency to increase in
diameter due to hydrostatic pressure
• This increase in diameter all along the height
of the tank depends on the nature of joint at
the junction of slab and wall
23
24
Tank with flexible base
Tank with rigid base
• When the joints at base are flexible,
hydrostatic pressure induces maximum
increase in diameter at base and no increase
in diameter at top
• When the joint at base is rigid, the base does
not move
