Main Uses
🔹 Septic Systems
- Placed around pipes in the drain field (leach field).
- Enhances the natural filtration of wastewater into the soil.
- Prevents clogging since it is free of clay, silt, and organic matter.
🔹 Drainage and Filtration
- Used in sand filters to improve treated water quality.
- Applied in infiltration systems, ensuring water flows easily.
🔹 Construction & Landscaping (secondary uses)
- Base for drainage trenches.
- Backfill material where proper drainage is required.
👉 Key point: controlled grain size (not too fine, not too coarse) allows constant water flow without saturating the system.
