OTHER USES OF CEMENT PIPE 



In addition to irrigation systems, there are many other forms of 

 construction for which cement pipe is admirably adapted. Among 

 them are sewers, culverts, drain tile, gates, underflow collecting 

 flumes, and water pipe lines. 



SEWERS 



At the present time over eighty American cities are giving the 

 preference to cement pipe for sewers. Bulletin 55, issued by this 

 Station in 1907, advocated its use very strongly. Quoting from that 

 bulletin, page 181, 



"For many years it has been an active competitor of clay tile in 

 sewer construction despite the usuallv much lower cost of the latter. 

 The city of Brooklyn, N. Y., has used cement sewer pipe almost ex- 

 clusively for forty years, and now has over 400 miles of cement 

 sewers in active use. No less an authority than Rudolph Hering 

 advocates it in preference to clay tile*. Its advantages are many. 

 It can be molded to any sectional form and will retain it, while 

 vitrified pipe shrinks and warps while burning. It is tougher than 

 vitrified pipe and withstands rough handling with less breakage. 

 When washed inside with pure cement it is equally as smooth and 

 frictionless as clean glazed tile, while both pipes soon become so 

 coated with sewage that the character of the original surface is lost. 

 In Arizona, conditions are especially suited to the use of cement 

 sewer pipe. The long freight haul makes vitrified tile very costly. 

 For the 8-inch size the cement pipe will cost 30 per cent less than 

 the tile, and in the larger sizes the economy will be still greater. 

 Throughout Arizona these conditions are practically the same, and 

 it is to be recommended that each city use the cement pipe. It can 

 be made by the city or contracted to an experienced cement worker, 

 in either case under the supervision of the city engineer." 



Despite this publicity, Arizona cities have continued to use clay 

 pipe for sewers. A large sewer contract was let in Tucson in 1916. 

 The lowest bid for the inside city work (excluding the outfall sewer) 

 was $66,305 for McCracken machine-made cement pipe. But, owing 

 to a malicious campaigner against the use of cement pipe for 

 sewers, the city accepted a bid of $73,612 for vitrified clay pipe. 

 Inconsistently, however, at the same time the city accepted a bid of 

 $41,750 for a 30-inch cement pipe outfall sewer. 



When the contract was about half completed controversy arose 

 over the quality of the clay pipe that was being furnished for the
