You have been asked to determine the optimum number of manholes for use in your subdivision. The sewer run is 2000 feet long. The pipe has a 3 foot/100 ft drop from end to end. Pumps cost $1,200 each. Manholes cost $600 per foot^1.2. Thus a 17 foot deep manhole would cost you $600*17^1.2 = $17,975.87.The pipe costs $20/foot.hus if the pipe segment were 400 foot long it would be embedded to an average depth of 11 feet and cost $6889.08, for a total job embedment cost of $34445.38.
