Sand Traps are used in which locations?

• A. Garages, Car washes, Workshops
• B. Residential bedrooms
• C. Public parks
• D. Schools

Answer: (A)

Sand traps are placed where wastewater is likely to carry sand, grit, and other heavy solids. In garages, car washes, and workshops, activities create a lot of abrasive debris—from vehicle grit and metal shavings to dust from sanding and grinding. The sand trap slows the water and lets these heavier particles settle out, protecting pipes, pumps, and the rest of the drainage system from clogging and wear. It’s a practical, common feature in these environments. Residential bedrooms don’t generate such solids, and parks or schools typically deal with rainwater or general wastewater that doesn’t require a sand-trapping device, so a sand trap isn’t normally used there.
