Who We Are
Valley Drilling Co is a family-owned septic and drilling contractor founded in 1950 and based in Cherry Valley, California. For three generations, the same family has installed, pumped, repaired, and designed on-site wastewater systems for homeowners, builders, and businesses throughout Southern California — with Yucaipa and Redlands as our home ground.
We operate alongside our sister company, Payless 4 Plumbing — plumbing, septic, and drilling under one family name, with the same crews and the same standards.
