5. Advantages and Economy of Reinforced Concrete Pipe. 



The great advantage of reinforced pipe is its durability. The first co 

 as compared to wooden pipe is usually a little greater, but its longer li 

 will make its ultimate cost much lower, especially when the pipe can m 

 be kept constantly full. 



It has been shown that for a wooden pipe whose life is 10 to 15 yea 

 the total annual cost to pay interest on first cost, renewal and depreciatio 

 is 15 per cent, of the first cost, and for a wooden pipe whose life is 20 1 

 30 years, about 11 per cent. For a concrete pipe, depreciation and r 

 newal are practically eliminated; therefore interest only, at about 6 pi 

 cent., need be considered. Based on these figures a concrete pipe would 1 

 as economical in cost as a wooden pipe even when the concrete pipe co 

 about twice as much as the wooden one. The prices of wire wound woe 

 pipe good for 50 to 100 feet head are about as follows for the Okanaga 

 district: 



6 inch pipe $ .28 per lineal foot
