Do I need a permit for septic system excavation in New Hampshire?

Yes. All NH septic systems require a permit from NH DES or your local municipality. A licensed NH septic designer must create the design first. Work must be performed by a licensed installer. Visit des.nh.gov for current requirements.

What excavator size do I need for a septic system in NH?

Most residential NH septic installations use a 3.5 to 5.5 ton mini excavator such as the Kubota U35, KX040, or U55. Tight access sites may need the compact K008 or U17. Deep systems or ledge conditions may require the KX057 or CAT 308.

How deep does a septic system need to be in New Hampshire?

Tank pits are typically 4 to 8 feet deep. Leach field trenches run 2 to 4 feet. Actual depths depend on your licensed designer's specifications based on soil evaluation results and NH DES requirements.

Can I rent an excavator and install my own septic system in NH?

No. NH law requires septic systems to be designed by a licensed designer and installed by a licensed installer. You can rent equipment to support the project but the actual installation must be done or directly supervised by licensed professionals.

What do I do if I hit ledge while excavating for a septic in NH?

Stop and call your licensed designer immediately. You may need a mound system or other engineered alternative. NorthPoint rents hydraulic breaker attachments when your designer approves that approach.
