Understanding How a Septic Drain Field Works
A drain field—also called a leach field—consists of perforated pipes connected to your septic tank. As wastewater flows out of the tank, it travels into the pipes and disperses into the surrounding soil. During this process, the soil naturally filters out contaminants before the water reaches the groundwater supply.
Planning and Layout Considerations
Every drain field needs a custom design. This is because soil type, slope, and system capacity differ by property. For example, if your property is on a slope, we install the leach field downhill from the septic tank to maintain gravity flow. In addition, we typically use a grid layout with pipes spaced 10 feet apart for optimal distribution and drainage.
Our Step-by-Step Installation Process
We follow a structured approach to ensure quality and long-lasting results:
- First, we excavate trenches to the correct depth and slope
- Next, we create a gravel base to support drainage
- Then, we install perforated piping
- Afterward, we backfill the trenches using clean gravel and soil
- Finally, we grade the field to promote water runoff and prevent erosion
Why Quality Construction Matters
Proper installation ensures your drain field performs well for decades. That’s why we follow best practices from the initial soil test to the final grading. Our team handles every detail with care and precision. Request your custom quote today and discover why Central Valley homeowners trust MCM Plumbing.
Is Repair an Option?
In some cases, yes. We can fix minor problems like clogs or cracked pipes without replacing the entire system. However, if you notice persistent sewage smells, soggy soil, or frequent backups, it’s likely time for a full replacement. Regardless of the issue, we’ll perform a complete evaluation and recommend the best solution.
