Effective dewatering is critical for safe construction. Learn how to select and deploy pumps for construction site water management.

Construction site dewatering keeps excavations dry and safe. Here's a comprehensive guide:

Foundation pit dewatering

Trench dewatering

Tunnel dewatering

Open-cut excavation

Solids content: Construction water typically contains sand and silt — use dirty water pumps with 35mm+ solids passage

Flow rate: Calculate inflow from groundwater, rainfall, and surface runoff

Head: Total vertical lift plus pipe friction losses

Portability: Construction sites require pumps that can be moved easily

Primary pump: High-capacity dirty water pump (1100W–1500W)

Backup pump: Same capacity on standby

Discharge: Route water away from excavation to prevent re-infiltration

Check strainer every 4 hours in heavy silt conditions

Monitor motor temperature

Inspect power cable for damage daily
