Accessing a septic system shouldn't mean tearing up the whole yard.

We installed new inlet and outlet risers to grade for a property in Bowling Green, making future maintenance cleaner and simpler. By bringing everything up to ground level, there's no more digging when it's time for pumping or inspection. Each step is handled with care so the yard stays neat and everything works as it should.

Want to keep your system running smoothly? Reach out any time for help with repairs or upgrades.

Wet spots in the yard are never a welcome surprise.

For this Genoa homeowner, we tackled a septic system repair that meant installing new risers, an outlet baffle, and a fresh distribution box. We replaced the outlet line to the d-box, jetted the leach field, and made sure everything was pumped and flowing as it should.

By addressing each part of the system, we helped prevent future backups and kept the property safe and usable. If you notice signs your septic system isn’t right, we’re ready to help.

🚜💪 Dig it up. Scoop it out. Swing it around. That’s how MSS gets down!

Big iron, moving dirt, and getting the job done! 💪
