How We Do It

At Sims Septic Pumping & Repair of Nipomo, California, we know that proper grading and trenching are critical to the success of any septic system or leach field installation. Serving homeowners throughout San Luis Obispo County and the Central Coast, our team brings the right equipment, skills, and local experience to ensure your septic system is built to last.
 

Why Grading & Trenching Matter for Septic Systems

When installing or repairing a septic system, accurate grading and trenching make all the difference. Grading ensures that wastewater flows smoothly through the system, while trenching provides precise pathways for leach lines and pipes. Done incorrectly, the result can be:

• Poor drainage and septic backups

• Premature leach field failure

• Soil erosion and property damage

• Costly system repairs down the line

That’s why Central Coast homeowners trust Sims Septic Pumping & Repair for expert excavation, grading, and septic system preparation.

​

We use professional-grade excavation and grading equipment to handle the unique soils and landscapes of the Central Coast—from sandy soils in Nipomo and Arroyo Grande to the dense clay of Paso Robles. Our fleet includes:

• Excavators & Backhoes – for septic tank placement, trenching, and leach field installation.

• Mini-Excavators – ideal for smaller residential lots and tight access areas.

• Trenchers – cut clean, accurate trenches for leach field piping.
