What Does a Dewatering Contractor Do? (And When You Need One)

May 20, 2025

When you're preparing a construction site—whether for a foundation, pipeline, or excavation—groundwater can quickly become your biggest obstacle. That’s where a dewatering contractor steps in. But what exactly do they do? And how do you know when to hire one?

In this post, we’ll break down the role of a dewatering contractor, the services they provide, and the situations where bringing one onto your jobsite can save you time, money, and regulatory headaches.

What Is a Dewatering Contractor?

A dewatering contractor is a specialized professional or company that removes excess groundwater or surface water from construction sites using engineered systems. Their goal is to ensure dry, stable ground conditions so that construction can proceed safely and efficiently.

They handle everything from wellpoint system installation, sump pumping, and deep well dewatering, to filtration, compliance documentation, and site restoration.

Services Typically Provided by Dewatering Contractors

Here are the core services offered:

  • Site Assessment & Water Table Analysis

Evaluate soil composition, groundwater levels, and hydrostatic pressures.

  • Custom Dewatering System Design

Develop solutions tailored to site conditions (e.g., wellpoints, deep wells, bypass pumping).

  • Installation of Equipment

Set up pumps, piping, filtration units, and discharge systems.

  • Monitoring & Maintenance

Regular site checks, water testing, and performance adjustments.

  • Regulatory Compliance

Ensure adherence to local, state, and federal water discharge and environmental standards.

  • System Removal & Site Cleanup

Once dewatering is complete, equipment is removed and the site is left construction-ready.

When Do You Need a Dewatering Contractor?

Not every project requires one, but here are common scenarios where hiring a dewatering contractor is critical:

  1. High Water Table

If groundwater is close to the surface, excavation is risky without proper removal systems.

  1. Foundation or Basement Work

Wet soil and water intrusion during foundation pouring can lead to delays and structural issues.

  1. Heavy Rainfall Areas or Flood Zones

Sites prone to flooding or heavy rain require ongoing dewatering to keep construction on track.

  1. Municipal, Industrial, or Coastal Projects

These jobs often involve strict environmental and safety regulations—professional oversight is a must.

  1. Emergency Situations

Sudden site flooding, utility breaks, or stormwater surges demand immediate dewatering response.

Benefits of Hiring a Professional Dewatering Contractor

  • Keeps Projects on Schedule

Prevent downtime from water delays.

  • Protects Workers & Equipment

Dry ground improves safety and accessibility.

  • Avoids Regulatory Fines

Ensures permits, discharge limits, and environmental controls are in place.

  • Reduces Long-Term Costs

Prevents damage, delays, and costly site remediation.
