Choosing the Right Septic Tank: Concrete vs. Plastic
One of the most important decisions when installing a new septic system is selecting the right septic tank material. At Big Bore Drilling, we help homeowners and businesses choose between concrete and plastic septic tanks based on site conditions, regulations, and long-term durability.
Concrete Septic Tanks
- Durability – Lasts 40+ years with proper maintenance.
- Stability – Heavy construction prevents floating or shifting
- Regulatory Approval – Preferred in most California counties.
Plastic Septic Tanks
- Lightweight – Easier to transport and install.
- Corrosion-Resistant – Won’t degrade from acidic soils
- Best for Inaccessible Areas – Ideal when boom trucks can't reach.

Understanding the Septic System Installation Process
- Step 1: Site Evaluation & Soil Testing
Before installation, we conduct a percolation test (perc test) to assess soil absorption rates, ensuring your septic system functions efficiently.
- Step 2: Obtaining Necessary Permits
Septic system installations require county-approved permits, which may include: - Septic System Permits
- Test Hole Permits (for soil analysis)
- Demolition Permits (for replacing old systems)
- Electrical Permits (if installing a lift station or pump)
- Step 3: Excavation & Tank Installation
Once permits are approved, we excavate and install your septic tank, ensuring proper placement and connection to leach fields, drain wells, or seepage pits.
- Step 4: Leach Field Construction & System Integration
We install the necessary drainage system, whether it’s leach lines, drain wells, or engineered systems, depending on soil conditions and regulations.
- Final Step: County Inspection & System Approval
After installation, your septic system undergoes a final county inspection to ensure compliance with local health and environmental regulations.

Plastic or Concrete Tanks: Is one better than the other?
- Concrete tanks are preferred due to their durability and stability.
- Plastic tanks are lightweight and easier to install in hard-to-reach areas.
- We only use the highest quality plastic tanks to prevent early failure.
How long do plastic septic tanks last compared to concrete tanks?
Concrete septic tanks can last 40+ years with proper maintenance.
Plastic septic tanks typically last 20-30 years but don’t corrode like concrete.
What factors affect choosing between plastic and concrete tanks?
- Soil Type: Acidic soils may degrade concrete over time.
- Water Table Level: Plastic tanks may shift in high water table areas.
- Installation Requirements: Concrete tanks require heavy equipment.
- Regulations: Some counties don’t allow plastic septic tanks.
What is the difference between a conventional and an engineered septic system?
- Conventional Septic Systems: Use a simple leach field for drainage.
- Engineered Septic Systems: Designed for challenging soil conditions or limited space.
What are Test Holes?
In Fresno County, test holes need to be dug before installing a new septic system or starting a septic repair. Test holes help to determine the porosity and permeability of the native soil on our property.
What are Leach Lines?
Leach lines allow water from your septic tank to leach back into the ground. These long trenches are filled with gravel and they are fed by a perforated pipe. Water flows through the pipe and leaches through the gravel and then into the ground. Click here for more information on leach lines.
