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.

Portland sits on the Highland Rim, about 800 feet up and close to the Kentucky line. The silt loam soil here often holds a fragipan, a dense layer 18 to 36 inches down. Water moves through that layer slowly, so a wet winter leaves drain fields soaked. That is when homeowners see soggy grass over the field and drains backing up inside.
Wiley Rooter and Septic Pros is based in Greenbrier, about 20 miles southwest of Portland. We install and repair septic systems across Sumner and Robertson counties, and we handle the rooter side of the work. We bring 20 years of septic and sewer experience, and we are licensed, insured and bonded. Call or text (629) 285-6381 for a free estimate, or to book septic tank pumping.

The city of Portland runs its own water and sewer service. Its utility pages list about 8,352 water customers and roughly 3,750 sewer connections. Most of that sewer sits under the older part of town and the newer subdivisions inside the city limits. Homes past the sewer line run on a septic system.
Head out toward Mitchellville, Oak Grove, or the Orlinda side of SR 52, and septic is the norm. The same goes for the acreage along SR 109 and the county roads north of town. We work both sides of that line. When it is not clear whether the tank or the field is failing, a septic inspection settles it.
Part of Portland reaches over into Robertson County. That line does not change how a septic system is built or permitted here. Both counties fall under the same state program.
Tennessee's state soil, Dickson silt loam, is a Highland Rim soil. Its official description puts the fragipan 18 to 36 inches down. Water moves slowly to very slowly through that layer. Sango, another Highland Rim soil, sits on upland flats and can pond for short periods.
A drain field only works if the soil below it can take water. When a dense layer sits two or three feet down, effluent has nowhere to go. It spreads along the trenches and comes up as wet ground. Sinkholes and limestone are common across Middle Tennessee, which is another reason field design gets checked closely here.
Wet spots over the field and a sewer smell in the yard both point at the field. So does a tank that fills right back up a week after pumping. That is drain field repair work, and it starts by checking how much of the old field still takes water. When the old trenches are worn out, we build new gravel and fabric lines.
Portland keeps growing. The 2020 census counted 13,156 people, up from 11,480 in 2010. Published permit data counted 76 single family building permits in Portland in 2025. Names like Rockland Estates on North Broadway and Ruby Springs on College Street have come through the planning commission.
A new home outside the sewer footprint needs a permitted septic system. In Tennessee, that runs through the Department of Environment and Conservation, Division of Water Resources. Sumner and Robertson counties both fall under its Nashville Environmental Field Office. A state approved soil consultant evaluates the site, and the soil report sets the size of the field.
Septic tank installation on a new build starts with that soil work. We set precast concrete tanks with a boom truck and plumb them to the house. Then we tie the tank into the field, set risers and lids, and backfill after the inspection. We do our own excavation, so the site work and the system stay on one schedule.
Portland grew up around the railroad and was called Richland before it took its current name. The older homes near the middle of town have older yard lines to match. Clay and cast iron pipe cracks, sags, and takes on roots after enough years. That is where a slow drain turns into a backup.
We run a camera through the line first when the problem keeps coming back. The video shows the break, the belly, or the root ball, and it shows how deep to dig. Sometimes the fix is a spot repair. Sometimes the whole run between the house and the tank has to come out.
Sewer line repair in town sometimes crosses a street. Our crew saws the asphalt, sets the new line, compacts the trench, and patches the road behind it. For a single clog in a toilet or kitchen line, a cable machine is usually enough.

We run a camera through your sewer or drain line and watch the video as it goes. That shows the break, the roots, the sag or the offset joint, and where it sits in the yard.
