Expert Septic System Installation in Groton, NY

Septic system installation in the Lansing area takes more than digging a hole and dropping in a tank. TMT Excavation & Outdoor Services handles the full scope: site assessment, excavation, tank placement, drain field layout, and backfill. We work across Ingham, Eaton, and Clinton counties, where heavy clay soils dominate much of the tri-county region. Clay holds water and limits drainage, which often means a conventional gravity system will not pass a soil evaluation. We have the equipment and field experience to work through clay conditions and install systems that meet county health department standards. Lansing-area townships like Delhi, Meridian, and DeWitt all have homes on private septic, and many older systems in these communities are past their service life. If your property needs a new installation or a full replacement, call TMT Excavation & Outdoor Services to get the process started.

Septic System Installation FAQ

Common questions about septic system installation in Groton, NY.

It depends on your soil conditions and lot size. In much of the Lansing tri-county region, heavy clay soils or high water tables may require an alternative system design instead of a standard gravity system.

Yes, Ingham County requires a soil evaluation before any new septic system design is approved. Test pits are dug to check drainage, water table depth, and soil structure on your specific lot.

Yes, we work regularly in the heavy clay soils common across Ingham, Eaton, and Clinton counties. We use excavators suited for clay trenching and proper backfill materials to support drainage around the tank.

A failing system must be repaired or replaced before the property transfer can close. We can assess the existing system and complete the excavation and installation work needed to bring your property into compliance.

Yes, county health departments in the Lansing region require a designated reserve area on your lot for future drainfield replacement. We account for this during site layout and excavation planning.

Tanner (Owner of TMT Excavation) and his crew did an excellent job "refreshing" and expanding my long gravel driveway. The driveway had not been updated in 20 yrs...the entire job from estimate to completion was very professional (yet friendly!) and I even received guidance on NYS tax exemptions for capital projects. The job was completed in less than a day and I love it!

Last summer our sewer line had a clog between the house and the street. Several attempts to clear it from the house were unsuccessful. TMT was able to come out on very short notice with their excavator and add clean-out access to the sewer line in our front yard. All in pouring rain too! Great Service!

We are extremely happy with how Tanner and crew have moved our vision from paper to dirt and stone. Can’t wait until spring to see it come to bloom!

I can’t recommend TMT Lawn Mowing enough! We’ve been using their services for both our personal home and rental property, and they’ve consistently exceeded our expectations. Theo mulch they provide for our gardens is of excellent quality, giving our outdoor spaces a fresh, vibrant look every season. They take great care in delivering exactly what we need! In the winter, their snow plowing service for our rental property has been a lifesaver. Their team is prompt, professional, and always ensures that our driveway is clear, even after heavy snowfalls. Their reliability is unmatched, and we feel completely confident in their services year-round. If you’re looking for a dependable, knowledgeable landscaping and plowing company that truly cares about their customers, look no further!

My daughter is a second year graduate student at Cornell and she has no time to shovel. Since I live out of state, I had to find a company to plow for her which was not an easy task. It is my second winter using TMT for snowplowing and I could not be more happy. They have done a wonderful job and I do not have to worry about my daughter getting stuck in her driveway. Even though I live states away, communication has been so easy. Great company and great job to all involved!
