What Is Silt?What do you call it?
• Silt • Slime• Mud• Sludge • Mire • Sediment• Muck
2
Sediment/Silt From Construction

Poor Water Quality
6
Site Accessibility for Heavy Equipment
Area Needs to be Dewatered
Bottom Damage Can Occur if Not
Dewatered When Working in the Blind
Rainy Weather Stops Work
Material Removal Messy
Not Friendly to Aquatic Life
Typical Problems with using ordinary excavation equipment to
do maintenance sediment removal from ponds and basins:
