Concrete Washout
A designated area for washing out concrete trucks, pumps, and tools to prevent highly alkaline runoff from contaminating groundwater.
Inspection Checklist
- Plastic lining must be free of tears and holes.
- Signage should clearly identify the area.
- It should be located away from storm drains (typically 50ft+).
- Perimeter berms should be intact.
Common Failures
- Overflowing: Washout liquids spilling over the berm.
- Leaking: Tears in the liner allowing liquids to seep into the ground.
- Improper use: Trash or other debris thrown into the washout.
Maintenance & Corrections
- 1. Vacuum out liquids or allow to evaporate and harden.
- 2. Dispose of hardened concrete properly off-site.
- 3. Replace liner immediately if damaged.
Inspection Freq: Before each pour and weekly.
