Explain the process for establishing the line and grade for a sanitary sewer line connection to an existing municipal sanitary manhole. Include the type of sewer flow, the importance of the pipe invert and reach of the sewer in determining the slope of the pipe, factors that determine the use of manholes, the use of batter boards and offset stakes, minimum ground cover required. In addition, discuss the use of visual aid such as field notes and a simple plan and profile drawing in establishing the line and grade.

A new development is being planned, which will connect to the city ’s sanitary sewer system. This development will have 80 acres of medium-density residential assume 10 DU / acre and 2.8 persons per DU). Assume a per capita sewage rate of 90 gal/d/person. Additionally, a new community hospital will be constructed with 300 beds (assume 300 gal/d/bed). Assume I/I contribution of 10%. a. Calculate the mean sewer discharge (accounting for residential, commercial, and I/I flows). b. Calculate the maximum...
