Leach Line Installation
Engineered for Flow. Installed with Precision.
A septic system is only as good as its leach lines. That’s why we approach every leach field installation with expert planning, code-compliant grading, and long-term functionality in mind.
At Major Concrete, we install and replace leach lines across El Dorado County and neighboring foothill communities—ensuring your septic system works from day one.
What Are Leach Lines?
Leach lines (also known as drain fields or absorption trenches) are the final step in a septic system. They safely disperse treated wastewater into the surrounding soil—but only when installed at the proper depth, length, and grade.
Our Leach Line Services
Whether you’re building a new septic system, replacing a failed drain field, or expanding for a remodel or ADU—we handle the excavation and installation with care.

Why Leach Line Work Must Be Precise
Leach lines that are too shallow, improperly graded, or over-compacted will fail—leading to flooded drain fields, backups, and expensive repairs.
We make sure it’s done right, with proper slope, spacing, and compaction to ensure steady percolation and clean groundwater.

New builds needing septic systems
Failing leach fields or code-required upgrades
Home additions or ADUs requiring system expansion
Plumbers and contractors needing reliable excavation
