Septic Installation
New septic systems for new builds and replacement tanks when an old one gives out. We dig with our own equipment, set the precast concrete tank, plumb it, and tie it into the drain field.

Gallatin maps a sewer service area, and plenty of Sumner County sits outside it. Drive out toward Castalian Springs, Bethpage, or Cairo and the houses run on septic. Those systems sit in heavy clay over limestone, which drains slowly. After a wet winter, a soggy yard or slow drains often point to a drain field problem.
Wiley Rooter and Septic Pros is based in Greenbrier, about 20 miles west of Gallatin. We install and repair septic systems, pump tanks, rebuild drain fields, and clear clogged lines. We bring 20 years of septic and sewer experience, and we are licensed, insured and bonded. Estimates are free, and you can call or text (629) 285-6381 to book septic tank pumping or a service call.

Gallatin is the county seat of Sumner County, and the Gallatin Public Utilities Department runs city water and sewer. The city maps a sewer service area, and inside that line most houses tie into it. Outside it, the county roads run on septic. Sumner County covers 543 square miles, and Gallatin itself is under 35 of them.
We work the roads east and north of town where septic is the norm. Castalian Springs sits about seven miles east on State Route 25. Cottontown, Bethpage, and Cairo all sit well outside the city sewer area. On those roads we pump tanks, fix pumps and alarms, rebuild failed fields, and set new tanks.
Gallatin has grown fast. The 2020 census counted 44,431 people, and a 2024 estimate put the city near 52,489. The city's own development list names dozens of active projects, including Kennesaw Farms and Cumberland Landing. When land is annexed, sewer is extended at the developer's expense, and acreage past that stays on septic.
Sumner County runs from the Nashville Basin up onto the Highland Rim. Basin ground is built on Ordovician limestone. Around Gallatin that means clay soil sitting over rock, and clay drains slowly. Water leaving the tank has to soak into that clay, and it takes its time.
Gallatin sits at about 538 feet, with the Cumberland River three miles south and Old Hickory Lake to the southwest. Bottomland near the river and the lake holds water longer. Wet winters and springs load a field that is already slow. Wet spots and odor over the field are the signs to watch.
Septic permits in Sumner County run through the Tennessee Department of Environment and Conservation. Its Division of Water Resources issues the construction permit, for a new system and for repairs to a failed one. The Nashville Environmental Field Office covers Sumner County. An approved soil consultant evaluates the soil, and that evaluation sets the field size for a septic tank installation.
Inside the sewer service area there is no tank, but the line under the yard still fails. Roots find joints. Old clay and cast iron crack or sag. We run a camera down the line first, so the digging goes where the problem is.
Some Gallatin lines cross a street to reach the main. Our crew saws the asphalt, sets the new line, compacts the trench, and patches the road. The excavation and the road patching are ours, so sewer line repair runs start to finish with our own equipment.
The rooter side gets its own calls. Clogged toilets, slow tubs, and main line stoppages get cable machines and professional drain cleaning equipment. On a septic home, a drain that keeps backing up can point at a full tank. We check the tank before we start drain cleaning.
Homes change hands fast in a town growing this way. When the house is on septic, the buyer or the lender usually asks for a septic inspection. We locate the tank, open the lids, and check levels, baffles, the pump and the alarm. Then we look over the field for wet ground and odor.
Pumping the tank before a sale makes the inspection cleaner. It also gives a clear look at the inside of the tank. If the report comes back bad, we price the repair and the seller knows what is in front of them. Estimates are free either way.
