How Does a Septic Drain Field Work?
A drain field (also called a leach field) is a network of perforated pipes connected to your septic tank. Wastewater flows from your home into the septic tank, where solids settle and liquids rise. The clarified liquid effluent exits the tank and enters the drain field. From there, it seeps out through small holes in the pipe and is naturally filtered by the soil as it percolates downward, eventually re-entering the groundwater supply.
Septic Drain Field Layout & Design
Every property requires a unique drain field layout. Factors like property slope, soil conditions, and septic system capacity all influence design. Pipes are generally laid in a grid pattern, spaced approximately 10 feet apart. On sloped properties, the leach field is typically positioned downhill from the septic tank to ensure proper flow by gravity.
How We Install a New Septic Drain Field
When installing a new septic drain field, MCM Plumbing follows industry-standard best practices:
- Excavate trenches to the proper depth and slope
- Install a base layer of gravel for drainage
- Lay perforated drain field pipes across the trenches
- Backfill with additional gravel and cover with barrier fabric
- Top off with at least 12 inches of soil for final coverage

Can a Septic Drain Field Be Repaired?
In some cases, yes. If your drain field has a clogged, crushed, or cracked pipe, targeted repairs may restore functionality. But if your leach field constantly smells, backs up, or leaves soggy patches in your yard, a full drain field replacement may be necessary.
Our team can inspect the system, assess soil saturation, and recommend the most practical solution—whether that’s repair or complete system replacement.
