The Inland Empire is the biggest septic region in Southern California — a huge number of homes from the Yucaipa and Redlands foothills to the Riverside valleys were built on septic and still run on it today. Valley Drilling Co has served this region from the middle of it, continuously, since 1950.
That 75-plus-year run matters for a simple reason: septic in the Inland Empire is local knowledge work. Soil that flips from decomposed granite to clay in a single block. County rules that differ on each side of the San Bernardino–Riverside line. Original systems from the ’50s and ’60s that need a contractor who has actually seen them before. We are a California C-42 licensed sanitation contractor with our own pump trucks, drill rigs, excavation equipment, and design and permits under one roof — one call covers everything from a routine pump-out to a fully engineered replacement system.
