Wastewater Characteristics and Sewer Design Fundamentals

Designing safe, efficient municipal infrastructure is one of the most critical responsibilities of modern civil and environmental engineers. Understanding what flows through our sewers and how to transport it safely is foundational to public health and urban planning. This comprehensive text-based course guides you through the essential principles of wastewater characterization and the mathematical and physical design of sewer networks. You will transition from understanding basic fluid properties to confidently sizing and layout-planning sewer lines using industry-standard formulas. What you'll learn: - Understand the physical, chemical, and biological characteristics of domestic and industrial wastewater. - Calculate sewage flow rates, peak factors, and dry weather flow for municipal areas. - Apply hydraulic formulas, including Manning's and Chezy's equations, to design sewer pipes. - Determine minimum and maximum self-cleansing velocities to prevent deposition and erosion. - Analyze sewer appurtenances and modern, sustainable stormwater management integration. - Practice fundamental design calculations through step-by-step written engineering scenarios. We begin with the absolute basics of environmental engineering terminology, defining key water quality parameters like BOD and COD. From there, we progress to hydraulic design principles, flow estimation, and structural layouts of sewer networks. Designed specifically for civil engineering students, entry-level environmental professionals, and candidates preparing for foundational engineering exams, this course requires no prior sewer design experience, though a basic comfort with algebra and fluid mechanics is helpful.
