A Homeowner's Guide to Choosing the Right Septic System
When you live in a rural area or a home not connected to a municipal sewer system, a well-designed septic system is essential for keeping your household running smoothly. At C&M Plumbing and Septic, we install, repair, and maintain all types of septic systems across Eastern North Carolina. Whether you’re building a new home, replacing an old system, or exploring upgrade options, it’s important to understand the different types of septic systems available—and which one may be right for your property.
Below, we break down the most common septic systems used today and how they work.
1. Conventional (Gravity-Fed) Septic System
Best for: Homes with good soil and plenty of space
A conventional system is the most familiar type of septic setup. Wastewater flows from the home into a septic tank, where solids settle at the bottom and oils float to the top. The partially treated water then travels to a drainfield, where the soil filters it naturally.
Advantages:
- Affordable installation
- Low maintenance
- Long-lasting when properly cared for
Considerations:
- Requires suitable soil
- Needs enough yard space for a drainfield
2. Chamber System
Best for: Properties with limited gravel availability or soil constraints
A chamber system works similarly to a conventional system but replaces traditional gravel drainfields with plastic chambers. These systems are ideal when gravel is scarce or expensive.
Advantages:
- Easier installation
- Performs well in various soil types
- Good for areas with high water tables
3. Pressure Distribution System
Best for: Sloped or shallow soils
Instead of relying on gravity alone, this system uses a pump to evenly distribute wastewater across the drainfield.
Advantages:
- More consistent treatment
- Works on challenging terrain
Considerations:
- Requires a pump (needs electricity and maintenance)
4. Mound System
Best for: High water table, shallow soil, or rocky terrain
A mound system creates an elevated drainfield made from sand and gravel. Wastewater is pumped into the mound, where it filters through the layers before reaching the natural soil.
Advantages:
- Works where conventional systems won’t
- Protects groundwater
Considerations:
- More visible in the yard
- Requires regular upkeep
5. Drip Distribution System
Best for: Small or irregular-shaped lots
This system uses drip tubing—similar to irrigation lines—to disperse wastewater slowly and evenly across the drainfield.
Advantages:
- Flexible layout
- Works in various soil conditions
- Requires less space
Considerations:
- Needs a larger pump tank
- Requires regular filter and pump maintenance
6. Sand Filter System
Best for: Areas with high water tables or poor soil absorption
Wastewater from the septic tank is pumped into a sand filter box. The sand provides an extra layer of treatment before the water enters the drainfield.
Advantages:
- High-quality filtration
- Good for environmentally sensitive areas
Considerations:
- Higher installation cost
