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.

Question

A yard waste composting windrow has a triangular cross section and is 10 feet wide at the base
and 10 feet high at the peak and 100 feet long. You may assume the waste has a specific
weight of 400 lb/yd^3 as placed in the windrow. The waste material is 40-percent biodegradable
and has the ultimate composition of C60H95O40N. Determine the amount of oxygen required to
stabilize the waste. Assume the aerobic degradation can be expressed as:
(4a + b — 2с + 3dу
b - 3d
