Septic Company
Orange County

Family-owned and C-42 licensed since 1950 — pumping, installation, engineering, and certification under one roof.

Orange County septic is a specialty. The canyon communities — Trabuco Canyon, Silverado, Modjeska, Santiago Canyon — and the older estate neighborhoods of North Tustin, Cowan Heights, Lemon Heights, Villa Park, and parts of Yorba Linda and Anaheim Hills never connected to sewer. Finding a contractor who genuinely knows these systems is the hard part.

We bring 75 years of septic engineering and field work to Orange County properties that most companies will not touch: hillside systems, aging tanks under mature landscaping, and county health department requirements for repairs and certifications. Pumping, camera diagnosis, repair, escrow inspection and certification, and engineered replacements — handled by a C-42 licensed, family-owned contractor with its own equipment and its own engineers.
