Use the finished drawing from Problem P8–6 to complete this problem. Add a sewer line to the house 30? from the west edge of the house. The sewer connects with a main sewer 30? south of the southern property line. Keep the sewer 10? east of the driveway. Show a cleanout (CO) 10? from the house. Show an additional CO between the house and the main connection, no farther than 100? from
the nearest CO. Create a plan and profile for the sewer installation. Do not show the entire property. Show contours on the plan. In the profile along the sewer, note the type of pipe, distance between cleanouts, and slope in ft./ft. Choose appropriate scales and an appropriate sheet size. Use the following information for this problem:
• House sewer pipe is 4?? ABS
• Sewer main is 8?? CSP
• Grade at house is 608?
• Sewer line IE at house is 603?
• IE at house CO is 602.5?
• Grade above sewer main is 584?
• Sewer IE at connection point is 574.80?
