Not sure if it’s time for a new septic installation? Here are some clear signs:
✔ Your current system is failing – Frequent backups, standing water near the drain field, or slow-draining sinks and toilets indicate your septic system may be at the end of its lifespan.
✔ You're building a new home – If your property isn’t connected to municipal sewer lines, you’ll need a reliable septic system designed to handle your household’s wastewater needs.
✔ Your family or business is growing – If your current septic system wasn’t designed for your household size or water usage, upgrading to a larger system can prevent costly problems down the road.
✔ Your drain field is saturated or failing – If wastewater isn’t properly filtering into the soil, your drain field may be clogged, damaged, or improperly designed, requiring a new system installation.
✔ Your system doesn’t meet local regulations – Older septic systems often fail to meet updated Oregon environmental and safety regulations, meaning you may need a replacement to stay compliant.psum dolor sit amet, consectetur adipisicing elit.

A septic system isn’t a one-size-fits-all solution. At Leonardo Excavation, we follow a step-by-step approach to ensure your installation is done correctly:
Every property is different, which is why we custom-design your septic system based on:
The size of your household (how much water you use daily)
The type of soil and terrain on your propertyLocal county regulations and permits
We install a variety of septic systems, including:
✅ Conventional Gravity Septic Systems
✅ Aerobic Treatment Units (ATUs) (great for properties with poor soil drainage)
✅ Mound Systems (ideal for areas with high water tables)
Once the design is finalized, our team:
✔ Excavates and installs the septic tank (concrete, fiberglass, or plastic)
✔ Lays out and installs the drain field (where wastewater naturally filters into the soil)
✔ Ensures proper slope and drainage to prevent backups and flooding
After installation, we:
✔ Conduct a full system test to ensure proper function
✔ Perform a final inspection to meet Oregon septic system regulations
✔ Walk you through proper septic maintenance to extend your system’s lifespan
