The book examines existing urban water supply system limitations, wastewater treatment technologies, and the integration of environmental engineering principles. Beginning with fundamental concepts like urban hydrology and water demand forecasting, it delves into water supply infrastructure specifics. Subsequent chapters explore advanced wastewater treatment technologies, including membrane bioreactors. Case studies demonstrate practical applications, culminating in integrated water resource management, emphasizing stakeholder collaboration. This comprehensive approach distinguishes the book, offering practical, evidence-based solutions for environmental engineers, urban planners, and policymakers.
