Collection Systems Built for Efficiency and Compliance
L4H Trenching designs and installs high-performance collection systems that manage groundwater, drainage, and leachate movement with precision. Using our advanced one-pass trenching process, we install collection trenches, sumps, and pump systems in a single, efficient operation. Each system is engineered to perform reliably under the static water table while meeting strict EPA, DEQ, and Army Corps of Engineers standards.
Why Collection Systems Matter
Collection systems are critical for controlling groundwater and preventing the spread of contaminants. Whether your project involves landfill leachate management, dam seepage control, or industrial site remediation, proper collection and drainage are essential for maintaining site safety and compliance. L4H Trenching delivers systems that protect both infrastructure and the environment.
Our One-Pass Installation Advantage
Traditional collection trench installation requires multiple stages of excavation, pipe placement, and backfill. Our one-pass system completes all of these steps simultaneously. The machine cuts, removes soil, and lays the pipe or collection media in one continuous motion, saving time, reducing costs, and improving safety.
Engineered for Adaptability
Every site has unique requirements for flow rate, soil type, and hydraulic performance. L4H collection systems can incorporate:
Sump and Pump Designs for active groundwater removal
Multiple Pipe Configurations for varied flow control
Permeable Media or Reactive Layers for treatment and filtration
Our system’s flexibility allows for precise adaptation to diverse soil and water conditions.
Common Applications
L4H collection systems are used for:
Landfill leachate collection
Groundwater remediation
Dam and levee seepage control
Dewatering trenches
Industrial site drainage
Slope and embankment stabilization
Proven Results That Save Time and Cost
Because our machine cuts, removes soil, and installs material simultaneously, L4H Trenching reduces total project duration, labor hours, and equipment use while maintaining precision and safety.
