A water or wastewater design is only as sound as the numbers behind it and the rule each number rests on.
On a real project, questions arrive together. How much oxygen will the aeration basins need? Will the contact basin earn its disinfection credit? What happens in the wet well when the power fails? Many references answer them as isolated textbook problems, yet the population projection sets the flows, the flows size the pipes, and the solids retention time you choose sets the oxygen demand, sludge production and nitrogen removal. Designers must also separate enforceable regulatory limits from consensus criteria, typical ranges and working assumptions. When those categories blur, a design becomes hard to check and harder to defend.
This book follows one town of 73,000 people through every chapter, from the first population projection to the last troubleshooting decision. It shows how hydraulics, chemistry, microbiology and process engineering become values on a design drawing, criteria in a permit application and decisions in a control room.
What this book helps you do
- See the system as a connected whole. Flows sized in the opening chapter become the pipes, clarifiers and plant hydraulic profile of later chapters, so each design choice can be traced across processes.
- Know what kind of number you are using. Every value is identified as a regulatory requirement, a consensus design criterion, a typical range or an illustrative assumption, with dated citations so current status can be confirmed.
- Follow and verify every calculation. Nearly 300 worked examples show intermediate values and can serve as templates once site-specific data replace the illustrative values.
- Design hydraulic and treatment systems. Work through pumps and surge, distribution networks, sewers and lift stations, coagulation and filtration, disinfection, activated sludge, aeration and nutrient removal.
- Handle solids, reuse and energy. Size thickeners and digesters, evaluate biosolids, assemble reuse treatment trains with pathogen log reduction credits, and estimate biogas recovery.
- Connect design to operation. Troubleshooting examples for drinking water and wastewater plants point back to the design chapters that explain why a process behaves as it does.
Inside the book
Sixteen chapters move from demand, flow and regulation through process fundamentals, water sources, pipe flow, distribution, collection, drinking water treatment, wastewater treatment, sludge and biosolids, advanced treatment and plant operations, including membranes, softening, ion exchange, corrosion control and trace organic contaminants such as PFAS. Each chapter offers learning objectives, panels on regulatory basis, design practice, calculation checks and operator observations, and a closing design synthesis. SI units are primary, with United States customary equivalents where practice uses them. Appendices, a glossary, references and an index complete the reference.
Who it is for
Civil and environmental engineers who design, review or operate water supply and wastewater systems, advanced undergraduate and graduate students preparing for that work, and plant operators and managers who want the design reasoning behind their processes. The methods support, and do not replace, the judgment of a licensed professional engineer.
Get your copy and start building water and wastewater designs you can trace from the first flow estimate to the final hydraulic profile, with every number and every requirement accounted for.
