Permit Handling
We handle all necessary documentation for septic tank replacement in LA County, ensuring a smooth and compliant process from start to finish. This includes preparing the site plan, conducting soil analysis, compiling engineering documents, and managing Health Department permit applications.
Excavation & Tank Removal
Our team uses precision equipment to safely remove your old septic tank and prepare the site for a seamless installation. We begin by locating and protecting underground utilities, then pump and properly dispose of any remaining waste. Finally, we lift and remove the old tank with care to ensure the area is ready for the new system.
New Tank Installation
Once the site is cleared, we install your new septic system with precise attention to grade, flow, and leak prevention. The tank is positioned on a compacted, leveled base, inlet and outlet pipes are securely connected, and all joints are sealed before thorough testing to ensure system integrity.
Drain Field Reconnection
We ensure your septic system operates smoothly by properly integrating the drain field. This involves attaching the effluent lines to the distribution system, applying layered backfill with gravel and sand for optimal drainage, and compacting the soil to prevent future settling.
