1 Call Septic Service, Inc is family-owned and operated right here in Minot, ND. Since the Wahus family started in the business in 2006, we pride ourselves on first rate customer service. Our company is licensed, bonded and insured. Other companies may offer similar services, but our services come with a personal touch. We encourage customers to watch while we service their tank, or build their waste water system, so we can explain what is being done and answer any questions you may have.
