Septic Installations Built for Arizona Terrain
Arizona Professional Excavating provides full-service septic excavation and installation, including tank placement, leach field trenching, and system layout alignment. Whether you’re building a new home off-grid or upgrading a failing system, we manage the dig and install process with efficiency and precision.
We work with certified septic designers and county inspectors to ensure systems are properly sized, approved, and installed according to environmental regulations. Our excavation techniques account for soil type, slope, and system type — conventional or alternative.
What Our Septic Services Include
Each job starts with a clear plan and ends with a fully functional, approved system designed to serve the property reliably for years to come. We coordinate with septic designers and health departments to ensure proper system sizing, layout, and compliance from day one. Our team handles excavation for tanks, trenches for leach fields, and any necessary soil modifications to meet local percolation standards. We also manage slope alignment for gravity-fed systems or prepare for pressurized alternatives. Every phase — from digging to backfilling — is executed with precision and documented for seamless inspection and final approval.
A Properly Installed Septic System Is Essential
Septic failure leads to groundwater contamination, system backups, and costly repairs. We ensure tanks are buried at the right depth, fields are graded properly, and systems are aligned with permit requirements — giving you a long-lasting solution from day one.
We provide complete septic installation services for residential properties including custom homes, ranches, cabins, and ADUs. Whether your site requires a basic tank and leach field or a more advanced engineered system, we ensure it’s excavated and installed with code compliance and long-term performance in mind. Our work accounts for space limitations, terrain, and soil absorption rates.
Conventional tanks
Leach field trenching
Soil-sensitive layouts
Commercial and high-usage properties demand more robust septic systems, and we’re equipped to deliver them. We install larger-capacity tanks, pressure dosing systems, and expanded leach fields tailored to meet increased daily wastewater volumes. Our team works closely with designers and local health departments to ensure each installation passes inspection and meets operational needs.
Larger tanks or dosing systems
Extended field trenching
Pressure system setup
When systems fail or reach capacity, we offer professional excavation and repair services to restore performance. From tank replacements and leach field reconfiguration to trench expansion and system upgrades, we handle each repair with minimal disruption to your property. We ensure all upgrades meet current code and pass re-inspection without delay.

Why Clients Trust Us For Septic Work
Our Septic System Installation Workflow
Our septic system installation process begins with a comprehensive site evaluation, including coordination with a licensed designer and soil testing to determine the appropriate system type and placement. Once approved, we excavate for the tank and leach field with precision, ensuring proper depth, slope, and layout for optimal flow and absorption. Throughout the project, we adhere to all county health regulations and prepare the site for required inspections. After passing all necessary approvals, we backfill, compact, and finalize grading — leaving the system ready for immediate use and the site clean and construction-ready.
