2. Due to enormous need by the public ,water has to be
stored and supplied according to their needs . Water
demand is not constant throughout the day. It
fluctuates hour to hour. In order to supply constant
amount of water, we need to store water. So to meet
the public water demand , water tank need to be
constructed.
3. A water tank is used to store water to tide over the
daily requirement. In the construction of concrete
structure for the storage of water and other liquids the
imperviousness of concrete is most essential.
Design of liquid retaining structure has to be based on
the avoidance of cracking in the concrete having regard
to its tensile strength.
Cracks can be prevented by avoiding the use of thick
timber shuttering which prevent the easy escape of heat
of hydration from the concrete mass the risk of
cracking can also be minimized by reducing the
restraints on free expansion or contraction of the
structure.
4. To make a study about the existing supply of
water and need for water storage in
To calculate the forces and stresses acting on
INTZE&RECTANGULAR water storage tank.
To make a study about the guidelines for the
design of liquids retaining structure according to
its code.
To design and analyze water tank structure
using manual method and STAAD pro software.
5. CLASSIFICATION BASED ON POSITION:
Tanks resting on ground
Underground water tanks
Elevated water tanks
CLASSIFICATION BASED ON SHAPE:
Circular tanks
Rectangular tanks
Intze tanks
Spherical tanks
Conical bottom tanks
PSC tanks

For smaller
capacities we
go for
rectangular
tanks
For bigger
capacities we
go for circular
tanks
Intze tank is
constructed to
reduce the
project cost
because lower
dome in this
construction
resists
horizontal
thrust
For bigger
tanks,
prestressing is
the superior
choice
resulting in a
saving of up to
20%
10. M20 grade concrete is used for
construction.
High quality
Leak proof
Should not crack
11. Permissible stresses should not
exceed the limit
Permissible stress in direct
tension=1000kg/cm2
Tensile stress in bending =1000
to 1200 kg/cm2
12. 0.3 % of gross cross sectional area must
be provided up to 100mm thickness.
0.2% of gross cross sectional area for 100-
450mm thickness.
0.2% of gross cross sectional area should
be provided for >450mm thickness in each
direction.
0.12% should be provided in foundation.
13. The objective of using them is to fill
the process of concrete and to obtain
a dense and less permeable
concrete.
Commonly used water proofing
material is HYDRAULIC LIME.
Other agents like chalks, sodium
silicate zinc sulphate, calcium
chloride etc…,are used.

39. Storage of water in tanks has become a necessity for drinking
and washing purposes day life.
For small capacities we go for rectangular water tanks & for
large capacities we go for circular tanks.
The designed RCC rectangular & Intze water tanks can store
water up to 10,00,000 liters.
In this design project we have design and analyzed the
overhead rectangular & Intze RCC water tank through
theoretical design and STADD Pro program.
Although the stresses and bending moment are nearly equal
but all the parameters used in the theoretical design cannot be
fully adopted in the program.
