Septic System Design & Permits in Arizona

What's Included in Our Septic Design Service

At Diaz Environmental LLC, we handle every step of the septic design process in-house. Because we own our own excavator and drilling equipment, we can move faster and at lower cost than competitors who subcontract this work.

• Site and soil evaluation
• Percolation testing
• ADEQ-compliant system design
• Permit submission to the county
• Coordination with your contractor or installer

Why Choose Diaz Environmental for Your Septic Design

We average 3–5 business days from soil testing to permit submission — one of the fastest turnarounds in Arizona. We are fully certified by ADEQ and have extensive experience with Maricopa County, Pinal County, and surrounding jurisdictions.

We also offer consultations in Spanish — ¡Hablamos español! — making us the preferred choice for Arizona's Spanish-speaking community.
