Septic Tank Installation in Nolensville, TN

One Family for Nolensville Septic Work

Nolensville sits at the headwaters of Mill Creek, about twenty miles southeast of Nashville in Williamson County. The town does not run its own sewer system, and the local utility district supplies water only. Metro Water Services covers sewer where the lines reach, which leaves a good share of 37135 on septic. Homes on acreage off Rocky Fork Road and Clovercroft Road usually treat their own wastewater. New subdivisions and old farms sit close together in Nolensville, so one block can split between the two. Nolensville has been the fastest growing city in Tennessee. Population went from about 5,900 in 2010 to nearly 13,900 at the 2020 census. That growth added houses in a hurry, while many older septic systems stayed exactly as they were built.

Septic Superior is a family septic company based in Thompson's Station, in the same county. Buddy Tomlin has worked septic in Williamson County since 2004, and he runs the work with his son. We install new septic systems in Nolensville and replace ones that have failed. We also take care of septic tank pumping and drain field work on systems already in the ground.

Where Nolensville Homes Still Run on Septic

Sewer service in Nolensville follows the main corridors and the newer subdivisions built along them. Step off those roads and the picture changes fast, even on the same side of town. Homes on an acre or more almost always treat their own wastewater in the yard. The same goes for older places near the historic stretch of Nolensville Road, where houses from the 1860s still stand.

Mill Creek starts in Nolensville, and much of the historic district sits inside its floodway. Low, wet ground slows a drain field down and shortens the life of the whole system. After a long stretch of rain, a field that was already tired stops taking water at all. That shows up as slow drains inside the house, or a soft and smelly patch out back.

Permits and Soil in Williamson County

Williamson County is one of nine Tennessee counties that permit septic work on their own. The Department of Sewage Disposal Management in Franklin handles it instead of the state. A construction permit is required before a system goes in or gets repaired. We handle that paperwork as part of the job, whether it is a new install or septic tank repair around Nolensville.

Middle Tennessee is limestone country, and the soil here can be shallow over rock. Williamson County treats any spot with less than 24 inches to rock as unsuitable for a drain field. A soil evaluation settles that question, and profile holes get dug at both ends of the proposed field. Two properties on the same Nolensville road can end up needing very different systems.

Nolensville FAQ

Questions From Nolensville Property Owners

A few of the questions we hear most around Nolensville. Don't see yours? Call us and ask.

Call (615) 957-9682

Is my Nolensville home on sewer or septic?
Check who bills you. Water in Nolensville comes from the Nolensville College Grove Utility District, which does not provide sewer. Metro Water Services bills the sewer where it reaches. If you see no sewer charge, you are almost certainly on septic. Look for a tank lid or a cleanout in the yard, and we can confirm it on site.
How much does septic work cost in Nolensville?
Price follows the ground and the job. Depth to rock, soil type, slope, and house size all change what a system needs. Permit and inspection work in Williamson County adds to it. A repair on a sound drain field runs well below a full replacement. We give free estimates after we look at the site.
We are adding a bedroom in Nolensville. Does our septic system matter?
Yes. In Tennessee a septic permit is tied to the number of bedrooms in the house. Add one and the tank and the drain field may both need to grow. Williamson County has to approve that change before the addition goes up. We check what your current permit covers and size the system from there.
