Collection Systems

The collection systems form a part of sanitary engineering, which is a sub-branch of civil engineering. It is also known as public health engineering and wastewater engineering. It is a methodology followed to remove and properly dispose of human waste, along with creating systems to provide safe and clean usable water. These measures ensure a hygienic and disease-free community. Sanitary engineering, apart from building sewer disposal units, is also involved in plumbing, fire protection, hydraulics, life safety, environmental protection, information technology, microbiology, pathology, and so on.

An averaged vitrified sewer pipe (n = 0.015) is laid on a slope of 0.0002 and is to carry 2.36 m3/s when the pipe flows 0.9 full. What size pipe should be used? only HANDWRITTEN answer needed ( NOT TYPED)
b.) Estimate the peak runoff flow rate observed in the combined sewer system in cfs generated only from storm water.
Design a concrete sewer required to carry a maximum design discharge of 10 cfs on a slope of 0.003. The minimum expected discharge is 2.5 cfs. Check the velocity for self-cleansing. Assume that commercial pipes are available in steps increasing by 0.5 ft (i.e. davail = 1 ft, 1.5 ft, 2ft, 2.5 ft...etc.)
2. A sewer line is to be designed to accommodate minimum and maximum flows of 30 m³/d and 1730 m³/d, respectively, with a self-cleansing shear stress of 1 Pa. The minimum allowable sewer diameter is 200 mm, and the ASCE design aids give Manning's n values of 0.0093, 0.0107, and 0.0121 for Extra Care, Typical, and Substandard conditions, respectively; and a minimum-self-cleansing slope formula of 0.00711Q5 -0.5724 where Qmin is in liters per second. (a) Verify the adequacy of the minimum-self-cleansing slope formula and assess the adequacy of using the minimum allowable pipe diameter and the minimum-self-cleansing slope to meet the minimum and maximum-flow conditions. (b) What is the maximum flow that the sewer segment can safely accommodate. " min
