We are a family-owned and operated small business located in Hillsville, VA. We service many counties throughout Southwest Virginia for Septic Design and Sewage Disposal needs. Stephen D. Dalton is a Virginia-licensed Onsite Soil Evaluator (OSE) and OSE Master Alternative — a certification held by only a small number of designers in the state. Since 2001, Stephen has owned and operated Southwest Soils, Inc. dba Southwest Soils & Water, and has designed drainfield and septic systems tailored to each client's specific needs. Honesty, integrity, and hard work guide every project we take on.
