The units stand side by side with parallel shafts, thesuctions being on opposite sides of the barge. Each suc-tion pipe is 10 in. in diameter and is equipped at thepoint where the pipe passes through the wall of thebarge, with a 10-in. Barco ball and socket joint, and thelower end of each pipe is equipped with a 45° elbow fac- piece of standard steel flanged pipe, and on the slope islocated another ball and socket joint, and from this pointto the normal ground surface, the pipe line consists offlanged asphalted spiral pipe. At the upper end of thepipe line, the water is discharged into a ditch. The pipe line is very light in construction and can bewithout very much effort lengthened or shortened by put-ting in or taking out a length of pipe. This was themethod used when the plant was first put in, as the waterhad to be pumped out and the plant lowered, as the canaldeepened. Due to the two ball and socket joints in the dischargeline, it is poss
