"Expect the best and get it!"

DaWayne Gourley founded Total Septic in 2016 with one simple mission — to provide honest, dependable, and high-quality septic and excavation services for homeowners and businesses across North Texas. What began as a small, family-run operation has grown into a trusted name throughout Collin, Grayson, Dallas, Denton, Rockwall, Fannin, and Hunt Counties.
With more than a decade of experience in the industry, DaWayne has built Total Septic around values of integrity, craftsmanship, and transparency. His hands-on leadership ensures every project — from a simple inspection to a full commercial excavation — is handled with precision and care.
At Total Septic, family comes first. DaWayne Gourley leads a tight-knit, experienced team that treats every property as if it were their own. Every technician is fully licensed, insured, and background-checked, giving clients complete peace of mind.
