Which design practice helps minimize flood risk in camps?

• A. Elevated latrines, proper grading and drainage, permeable surfaces, defined access routes, avoiding flood-prone areas
• B. Locate latrines in floodways
• C. Use non-porous impermeable surfaces only
• D. Ignore drainage planning

Answer: (A)

Minimizing flood risk in camps comes from designing sanitation and movement systems that stay functional when water rises and people need to move safely. Elevating latrines keeps waste above flood levels, preventing backflow and contamination of clean water sources. Good grading and drainage direct rainwater away from facilities and living areas, reducing ponding, erosion, and structural damage. Permeable surfaces let rainwater infiltrate rather than run off, lowering surface flooding and helping the overall drainage system keep pace with storms. Defining clear access routes ensures safer movement and avoids people wading through floodwaters or contaminated zones, which is crucial during emergencies. Avoiding locations in flood-prone areas minimizes exposure to active floods and protects both infrastructure and people. Locating latrines in floodways would place sanitation directly in the path of rising water, creating severe contamination and health risks. Relying on non-porous impermeable surfaces alone increases runoff, can worsen flooding, and hinders natural drainage and groundwater recharge. Ignoring drainage planning leads to water pooling, damage to structures, and greater disease risk. The best practice combines elevation, proper drainage, permeable surfaces, defined access, and avoidance of flood-prone zones to reduce flood risk effectively.
