Engineered Dewatering Solutions
Our Dewatering Capabilities
-
Deep Wells
High-capacity groundwater control systems designed for large excavations and deep cuts. Deep wells use submersible pumps to lower the water table efficiently in permeable soils.
-
Wellpoints
A flexible and economical dewatering method ideal for shallow excavations. Wellpoints are installed in a series and connected to a header pipe to draw down groundwater in sands and silts.
-
Vacuum Assited Systems
Enhanced wellpoint systems that apply vacuum pressure to improve performance in low-permeability soils, providing reliable groundwater control where conventional methods may struggle.
-
Eductor Systems
Also known as jet eductors, these systems use high-pressure water to create suction and remove groundwater in tight or low-permeability soils where traditional pumping is less effective.
-
Horizontal Wells
Localized water collection points within excavations that allow accumulated groundwater or surface water to be pumped out efficiently during active construction.

Sumps
It all begins with an idea. Maybe you want to launch a business. Maybe you want to turn a hobby into something more. Or maybe you have a creative project to share with the world. Whatever it is, the way you tell your story online can make all the difference.
Why Dewatering Matters in Houston
Supports Soil Stability
Houston’s clay-dominant soils lose strength rapidly when saturated, increasing the risk of cave-ins, settlement, and structural movement. Properly engineered dewatering lowers the water table, reduces pore pressure, and creates stable excavation conditions that protect foundations, utilities, and adjacent structures.
Ensures Regulatory Compliance
Groundwater discharge and stormwater management must meet state and local requirements, including standards set by the Texas Commission on Environmental Quality (TCEQ). HASS designs and manages dewatering systems with compliance in mind, helping contractors avoid violations, delays, and costly rework.
Protects Schedule & Safety
Water intrusion can halt excavation, damage equipment, and create hazardous working conditions. Effective dewatering minimizes slip hazards, reduces downtime, and keeps crews operating efficiently protecting both project timelines and on-site personnel.
Why Choose HASS for Dewatering
Years of experience combined with a commitment to innovation have allowed HASS to develop and refine equipment and systems capable of solving complex water handling challenges efficiently.
Because dewatering is fully integrated within our operations, contractors and engineers rely on HASS for streamlined coordination and comprehensive service. We frequently provide multiple services under one contract, reducing downtime, minimizing risk, and improving overall project efficiency.
