We handle septic tank installation in College Grove, TN, an unincorporated and mostly rural community in eastern Williamson County. It sits in ZIP 37046, about 13 miles east of our base in Thompson's Station. U.S. Route 31A runs through it. The Bank of College Grove building stands on that highway and is on the National Register of Historic Places. The water utility named for the community is the Nolensville/College Grove Utility District. That district does not provide sewer service, and it says not all areas have sewer. A home that pays for water but never sees a sewer charge usually has its own septic system. The Census Bureau's median year built for homes in 37046 is 2010. That means about half the homes in the ZIP went up in 2010 or later. Every new house on a lot without sewer needs its own tank and drain field.
Septic Superior is a family septic company based in Thompson's Station. More than 20 years of septic work in Williamson County sit behind the company. Our crew takes on septic system installation for new homes and full replacement when an old system gives out. Older systems get septic tank pumping and tank repair from us too. We file the permit and handle it from start to finish. Emergency septic service is available when a tank backs up. Estimates are free and done on site, where we look at the lot and hand you one price.

College Grove was one of Williamson County's early communities, and the county was founded in 1799. In the 1880s it had about 100 residents and three cotton gins, plus two corn and saw mills. Census Bureau estimates now put the wider 37046 ZIP at 6,632 people in 2,740 housing units. On new construction, our crew sets the tank and builds the drain field that goes with it. We can top the new tank with septic tank risers and lids so it opens at ground level.
The Harpeth River rises just east of College Grove, in the westernmost part of Rutherford County. A stream, a natural drainageway or a sinkhole on your lot brings Williamson County's setback chart into play. The chart puts a disposal field at least 25 feet from each one, and a tank 15 feet. Both stay at least 50 feet from a water supply. We place the tank and field to meet those distances. If the field sits uphill, a pump chamber with float switches sends the wastewater up to it.
Septic permits for College Grove come from Williamson County, which runs its own program. The office is the Department of Sewage Disposal Management in Franklin. Williamson is one of nine Tennessee contract counties. Most surrounding counties permit through TDEC, the state environment department. Filing that permit is part of our job on every install. Our guide to septic permits in Williamson County covers the steps.
On a College Grove lot, the county's regulation sets hard limits for the ground. A conventional system needs at least 36 inches of natural soil over bedrock. It also needs at least 24 inches of unencumbered soil over a restrictive horizon. Slopes over 30 percent are unsuitable for conventional and low pressure pipe systems. Conventional trenches run 36 inches wide and 24 to 30 inches deep. We coordinate the soil evaluation as part of the install.

Septic tank repair for cracked tanks, broken lids and risers, failed baffles, and backed up lines. We pull the lid and find the real problem before we quote the work.

We set risers and lids that bring a buried septic tank up to the grass, and we locate tanks nobody has records for.

A soggy yard or a sewage smell over the field lines means the drain field has stopped absorbing water. We find the failed section and repair it, from a single lateral to a full leach field replacement.

Septic tank maintenance keeps solids in the tank and out of your drain field. We measure the sludge and clean the filter, then set a pumping schedule that fits your household.

A septic tank inspection tells you what shape a system is in before you buy or sell. We open the tank and check the drain field, then put the findings in writing.
