As in the case of circular tanks, to attain the greatest security aga nst leaking, the Construe- 

 concrete should be poured in one operation. The ingredients should be selected carefully, " n 

 proportioned well and tamped thoroughly. 



Where the tank is elevated above the ground, the base must be designed as a floor Special 

 slab. .The services of an engineer should be obtained for this. Cases. 



As in the case of circular tanks, square tanks depressed in the ground may be designed 

 by the use of the tables. The same amount of reinforcement should be used continuously 

 near the inside face of the side walls that is required near the outside face. There will 

 thus be two layers of reinforcement instead of one. 



When it is desired to design a rectangular tank, proceed as in the case of a square tank, Rectangular 

 using the longest dimension of the rectangular tank as the side of the square. For Tanks. 

 example, to design a tank 10' x 14' and 6' in depth, select from tables 3 and 4 the pro- 

 portions of a tank 14 feet square and construct your tank accordingly. The 10 foot side of 

 tank should be reinforced with the same mesh as the 14 foot side and the walls to be of 

 the same thickness.
