Looking for something lightweight and easy to install? Plastic septic tanks are durable underground containers made from high-density polyethylene (HDPE) or similar materials. They collect household wastewater, allowing solids to settle and partially break down before the liquid effluent moves on to a drain field for final treatment.

Pros of plastic septic tanks:

• Lightweight – easier to transport and install without heavy machinery

• Corrosion-resistant – won’t rust or rot over time

• Watertight – less risk of leaks compared to some concrete tanks

• Suitable for sites with limited vehicle access

Cons of plastic septic tanks:

• Less resistant to crushing from heavy loads (e.g., vehicles driving over them)

• Smaller capacities than some concrete options
