Study Notes
Excreta Disposal
- Containment and safe disposal of human excreta is crucial to prevent the spread of excreta-related diseases
- Simple pit latrines are the most common technology choice in emergencies, quick to build
- Ventilated-improved pit (VIP) latrines are more expensive and typically used in institutions
- Ecological sanitation (Eco-San) recycles nutrients from human excreta for agriculture
- Double-vault urine-diverting latrines separate urine and feces, sometimes known as dehydrating latrines
- Double-vault non-urine-diverting latrines mix urine and feces, also known as the Fossa Alterna
- Biogas latrines capture gas from decomposing excreta for fuel
- Borehole latrines are constructed quickly, ideal where drilling equipment is available
- Pour-flush latrines rely on water to seal and remove excreta to a wet or dry disposal system
- Septic tanks collect and treat toilet wastewater and gray water
- Aqua-privies are built directly above a septic-tank, suitable when pit latrines are unacceptable
- Wastewater treatment systems include septic tanks, surface water disposal, subsurface discharge, and water reuse
Food Safety
- Food safety practices aim to reduce the risk of foodborne illnesses
- Foodborne illnesses are contracted from contaminated food or beverages
- Sanitation focuses on clean drinking water and safe excreta and sewage management
- Primary wastewater treatment removes solids
- Secondary wastewater treatment uses biological processes to purify water
- Vermin are wild animals harmful to crops
- A vector is an insect or animal that transmits disease
- Integrated Vector Management (IVM) is a strategic approach to vector control with five key elements: advocacy, collaboration, capacity-building, integrated approach to disease control, and evidence-based decision-making
- Methods of vector control include environmental management, chemical control, safe insecticide use, monitoring insecticide susceptibility, individual/household protection, and biological control
- The built environment is a significant source of energy consumption and greenhouse gas emissions
WHO 5 Keys to Safer Food (KSUCK)
- Keep clean
- Separate raw and cooked
- Use safe water and raw materials
- Cook thoroughly
- Keep food at safe temperatures
3 Types of Sanitation (WEW)
- Wastewater disposal (dirty/used water)
- Excreta removal (feces and urine)
- Water sanitation (drinking water treatment)
IVM Five Key Elements (ACCIE)
- Advocacy, social mobilization, and legislation
- Collaboration within the health sector and with other sectors
- Capacity-building
- Integrated approach to disease control
- Evidence-based decision-making
