CHAPTER 7 WATER TANK
7.1
INTRODUCTION
As per Greek philosopher Thales, “Water is the source of every creation.” In day to day life one cannot live without water. Therefore water needs to be stored for daily use. Over head water tank and underground water reservoir is the most effective storing facilities used for domestic or even industrial purpose. Depending upon the location of the tank the tanks can be named as overhead, on ground or underground. The tanks can be made in different shapes usually circular and rectangular shapes are mostly used. The tanks can be made of RCC or even of steel. The overhead tanks are usually elevated from the roof top through column. In the other hand the underground tanks are rested on the foundation. Different types of tanks and their design procedure is discussed in subsequent portion if this chapter. The water tanks in this chapter are designed on the basis of no crack theory. The concrete used are made impervious.

TYPES OF WATER TANK
Basing on the location of the tank in a building s tanks can be classified into three categories. Those are: • • • Underground tanks Tank resting on grounds Overhead tanks
In most cases the underground and on ground tanks are circular or rectangular is shape but the shape of the overhead tanks are influenced by the aesthetical view of the surroundings and as well as the design of the construction. Steel tanks are also used specially in railway yards. Basing on the shape the tanks can be circular, rectangular, square, polygonal, spherical and conical. A special type of tank named Intze tank is used for storing large amount of water for an area. The overhead tanks are supported by the column which acts as stages. This column can be braced for increasing strength and as well as to improve the aesthetic views.
