Environmental Health and Sanitation - CE571

Credits : 2

Prerequisites : CE302

Compulsory/Optional : Optional

Familiarizing students with water related health issues and appropriate engineering control measures by introducing basic water microbiology, microbial risk assessments and sanitary waste treatment techniques.
Intended Learning Outcomes
On successful completion of the course, the students should be able to;

  1. Explain the sanitation related public health and assess the associated risk of environmental health issues for any related microbiological or chemical hazards in water.
  2. Devise control measures against microbiological hazards to minimize impacts on public health, using tools like Quantitative microbial risk assessment (QMRA)
  3. Plan appropriate water management systems by identifying relevant engineering control measures to combat against a given level of health risk
Course content/Course description
  1. Introduction to water supply and sanitation: Global Health, Global burden of disease
  2. Disease outbreaks: Public health and hygiene, history of waterborne diseases, microbiology of drinking water, transmission routes of waterborne pathogens
  3. Identify hazards and hazardous events and assess the risks: Microbiological risk, quantitative microbiological risk assessment, predictive microbiology
  4. Onsite and offsite sanitary treatment methods: Special emphasis on low cost and appropriate technologies suited to developing world, risk tradeoffs
  5. Microbial source tracking: Coliform bacteria detection techniques in water
  6. Water safety plans (WSP) and sanitation safety planning (SSP)
