Why Regular Septic Tank Pumping Matters

Many Montana homeowners wait too long to pump their septic tanks. This leads to:

Clogs and sewage backups

Drain field failure

Foul smells

Costly emergency repairs
Our recommendation?
  • Pump every 2–3 years for most residential systems
  • Pump more frequently for commercial use or large families
    We serve high-demand zones like Lockwood, Columbus, and Roundup, where rural septic use is heavy and systems are often neglected.
