Keep Your Septic System Working as Intended

Septic system installation and repair services for properties in Chattanooga, Tennessee.

When your septic system stops draining properly or you are building on a property in Chattanooga without public sewer access, you need someone who understands soil conditions, system placement, and how to coordinate excavation with septic work. Tolli's Construction installs new septic systems and repairs existing ones across Chattanooga and surrounding areas. The work includes everything from site evaluation and excavation to tank placement and drain field setup.

Septic installation involves digging to the correct depth, placing the tank and distribution lines, and backfilling the system to protect it while allowing proper drainage. Repairs address issues like cracked tanks, clogged lines, or failing drain fields. Soil type and property slope affect how the system is designed, and familiarity with local conditions helps avoid problems down the road. Tolli's Construction coordinates excavation and site prep as part of the septic process, so the work flows without delays.

If you need a new septic system installed or repairs made to an existing one in Chattanooga, reach out to discuss your property and get a clear plan in place.

How Septic Work Gets Done Right

Installation begins with evaluating your property in Chattanooga to determine the best location for the tank and drain field based on soil permeability, setbacks, and slope. Excavation creates the space needed for the tank, and grading ensures proper drainage away from the home. Distribution lines are laid in trenches filled with gravel, and the system is backfilled once everything is set and inspected.

After installation, your septic system will handle wastewater without backups or surface pooling. You will notice consistent drainage from sinks, toilets, and showers, and the yard above the drain field will remain dry and odor-free. Proper placement and excavation prevent future issues caused by poor slope or compacted soil.

Repairs may involve replacing a damaged tank, clearing blocked lines, or rebuilding sections of the drain field. If the system has been failing for a while, excavation may be needed to access and replace compromised components. Tolli's Construction evaluates the full system before recommending repairs, so you know what is needed and why.

Most septic questions come up early

Homeowners in Chattanooga often ask how long septic installations take, what signs indicate a failing system, and whether repairs can extend the life of an older setup.

What are signs that my septic system needs repair?
You may notice slow drains, sewage odors near the tank or drain field, wet spots in the yard, or toilets that back up frequently. These symptoms suggest blockages, tank damage, or a failing drain field.
How long does septic system installation take?
Most residential septic installations in Chattanooga take two to four days depending on system size, soil conditions, and site access. Excavation, tank placement, and backfill are coordinated to keep the project moving.
What affects where a septic system can be installed?
Soil permeability, property slope, setback requirements from wells and property lines, and access for excavation all influence placement. Tolli's Construction evaluates your property in Chattanooga to find the best location.
Why does soil type matter for septic systems?
Soil needs to absorb and filter wastewater properly without staying saturated. Clay-heavy or rocky soil may require adjustments to the drain field design or additional site prep during excavation.
When should I call for septic repairs?
You should call as soon as you notice drainage issues, odors, or soggy areas near the system. Early repairs prevent more extensive damage and avoid costly replacements down the line.

A failing septic system disrupts daily life and creates health hazards if left unaddressed, while a properly installed system works quietly for decades.
