Info

• A VIP Latrine is designed to reduce the number of flies within the latrine and to disperse the odor. − − Both of these tasks are done via the use of a vent which connected to the pit itself. The vent being the only source of light within the latrine, attracts the flies, effectively trapping them within the pipe until they die. http://www.cartercenter.org/resources/pdfs/health/ephti/library/lecture_notes/env_health_science_students/ln_human_waste_final.pdf
• Advantages − Cheap − Controls vector populations − The pit is lined with bricks to better control ground water pollution − Reduces odor • Disadvantages − Still has a chance of polluting ground water http://www.cartercenter.org/resources/pdfs/health/ephti/library/lecture_notes/env_health_science_students/ln_human_waste_final.pdf
