Experienced Septic Services in Central Utah
SG Mayne Excavation handles every phase of your septic project. Whether you're building a new home, replacing a failing system, or need a repair, we bring the equipment, expertise, and honest communication to get it done right.
We serve Sanpete, Sevier, and Juab Counties and work closely with county health departments to make sure your system meets all local requirements.
What We Do
Perc Testing & Site Evaluation
We conduct percolation tests and evaluate your property to determine the right system type and placement before any work begins.
Septic System Design
We work with the county health departments to design a system that meets local code and fits your property's specific conditions. We also help homeowners navigate the permitting process.
New Septic System Installation
We install full septic systems, including tank placement, drain field excavation, and all associated site work. Our experience includes challenging properties with steep hillsides, difficult access, and demanding terrain throughout Central Utah.
Drain Field Installation & Repair
Proper drain field layout and installation is critical to a long-lasting system. We excavate and install drain fields to spec, and repair failing ones.
Septic System Repair
From broken lines to failed components, we diagnose and repair septic problems efficiently to minimize disruption to your property.
Site Restoration
After installation or repair, we clean up and restore the work area, leaving your property looking as close to its original condition. Our goal is to leave you with a finished job - and hardly a trace that we were there.
