Learn how cities collect domestic wastewater through sewage networks and storm runoff, transport it to treatment plants, and apply sanitation-focused processes like waste stabilization ponds and activated sludge.
Understand sanitation as facilities, collection, transport, treatment, and hygiene that prevent contact with waste, emphasizing safely managed sanitation, reduced open defecation, and progress toward SDG 6 by 2030.
Address unsafe sanitation to reduce 756,000 deaths in 2019 and curb infectious diseases like cholera, diarrhea, and polio, while limiting child malnutrition and stunting.
Characterize domestic wastewater by origin and composition. Assess key parameters such as tds, tss, nutrients, microorganisms, dissolved oxygen, bod, and cod to guide treatment.
Treat wastewater before discharge to protect health and ecosystems. Remove pathogens, heavy metals, and nutrients to curb eutrophication and support clean water for fisheries, wildlife, and recreation.
Explore how urban wastewater travels from residents through sewers to treatment plants, undergoing preliminary, primary, secondary, and tertiary treatments—physical, biological, and chemical processes—to protect ecosystems.
Explore decentralized on-site wastewater treatment with septic tanks and centralized systems, comparing waste stabilization ponds and activated sludge for various tech levels.
Explore the major challenges facing wastewater treatment, including universal access, rising populations, and high costs. Examine greenhouse gas emissions, sludge management, disinfection, odor and noise, and emerging pollutants.
Transform raw wastewater into safe effluent through complex engineering and substantial investments. Highlight that resource gaps in poorer countries threaten public health and ecosystems while we pursue universal safe sanitation.
Every day, we use water for our basic needs, such as drinking, bathing, cleaning, cooking, and laundry. However, by doing so, we generate every day millions of liters of wastewater which end up in the sewage network.
These sewage networks transport all wastewater to large facilities called wastewater treatment plants. where it undergoes complex transformations to make it less harmful to the receiving ecosystem.
Managing daily flows of millions of liters of wastewater can be challenging, as it threatens public health and ecosystems.
For a better understanding of how cities manage daily generated wastewater fluxes, we will discuss in this course the topics of sanitation, wastewater, and wastewater treatment from many angles.
To do so, we will use the following plan :
Introduction
Chapter 1: Sanitation & hygiene
Chapter 2: Consequences and challenges of unsafe sanitation
Chapter 3: Wastewater characterization
Chapter 4: Importance of wastewater treatment
Chapter 5: Basic concepts of wastewater treatment
Chapter 6: Wastewater treatment processes
Chapter 7: Challenges of wastewater treatment
Conclusion
By the end of this course:
- You will have a better understanding of domestic wastewater management works and the importance of safe sanitation.
- You will understand the importance of safe sanitation and wastewater facilities
- You will learn about wastewater composition and the processes used to treat wastewater
- You will gain insight into different environmental and economic challenges for wastewater and water management and conservation.
I hope you enroll & enjoy the course!

Important Notice:
This course has been prepared with a specific audience in mind: learners looking for general knowledge about urban wastewater, the dangers of unsafe sanitation, wastewater treatment … and does not delve into engineering design and calculations of wastewater treatment.
That’s why:
- The course is suited for general public and provides high quality and concentrated knowledge about the importance of safe sanitation and how wastewater treatment works.
- The course is not suited for professionals, engineers and researchers looking for calculations and designs of wastewater treatment processes.
(No artificial intelligence tools (chatgpt, generative ai, prompts ..) were used in the development of this course, I believe this is important for providing an original learning experience for students).
