5 Highlights on Septic System Installation & Design

Septic system installation and design is the foundation of every reliable onsite wastewater treatment setup in rural Tennessee. We take care to ensure your septic systems function properly for decades. Here’s what sets our service apart:

Engineered Site Plans — Our licensed designer evaluates your soil profile, percolation rate, and water table depth to assess conditions and engineer an appropriate system that meets Tennessee Department of Environment and Conservation standards. Every as-built drawing reflects actual field conditions.
Full Perc Testing and Soil Analysis — We probe and test your property’s soil before we design anything. A certified soil scientist assesses sandy, loamy, or clay-rich conditions to determine the right absorption field configuration and recommend a system that will suit your property.
Conventional and Alternative Systems — We install gravity-fed conventional septic tanks, mound systems, aerobic treatment units with pump technology, drip irrigation systems, and low-pressure dosing configurations. Every component is installed using proven methods. Your property dictates the design.
Permitted and Code-Compliant Work — We pull every permit through your local health department and schedule all required inspections to ensure compliance. Our installations comply with Tennessee’s subsurface sewage disposal regulations from day one.
Turnkey Excavation and Backfill — Our crews dig, excavate, trench, install, connect, backfill, grade, and compact your entire system with no mess left behind. We protect your lawn and restore the landscape. One contractor handles the full scope from distribution box to drain field.

Signs You Need Septic System Installation & Design

Septic system installation and design is necessary in several clear situations. Recognizing these signs early saves you money, protects your groundwater, and keeps your property compliant with Tennessee health codes.

You’re building on undeveloped land: New construction on rural property without municipal sewer access requires a complete onsite septic system. You’ll need a perc test, soil profile evaluation, engineered site plan, and permitted installation before you can occupy the structure. This is the most common reason homeowners contact us. Request a free estimate to get started.

Your existing system has failed beyond repair: Saturated drain fields, collapsed concrete tanks, and cracked baffle walls signal a failing system. When effluent seeps to the surface, sewage backs up into the home, or your inspector certifies the system as non-compliant, the problem cannot be fixed through minor repairs. Replacement through new installation and design is the only real fix. Patching a failed system wastes money.

Your property’s use has changed: Converting a residential property to commercial use, adding bedrooms, or installing a guest house increases wastewater volume. An undersized or overloaded septic tank and absorption field can’t handle the added influent from additional plumbing fixtures. A redesigned system with a larger tank, expanded leach field, or pressurized dosing chamber accommodates the new load.

Your cesspool or cesspit needs decommissioning: Older Tennessee properties sometimes still operate on cesspools or outdated seepage pits. State regulations require you to abandon and decommission these systems and replace them with a permitted, engineered septic installation. We offer complete decommissioning and replacement services.

Your health department has issued a notice: When the county health department flags your property for sewage discharge, groundwater contamination, or an unpermitted system, you need professional septic system design and installation to remediate the violation and restore compliance.

Our Septic System Installation & Design Process

Septic system installation and design is a structured, multi-phase process covering every detail from initial evaluation to final inspection. Rural Septic TN follows a proven sequence that keeps your project on schedule and fully compliant.

Step 1: Site Evaluation and Soil Testing. We survey your property, probe the soil at multiple points, and conduct a perc test to measure the percolation rate. Our soil scientist identifies the water table depth, soil texture, and any subsurface limitations like rock or saturated clay layers.

Step 2: System Design and Engineering. Based on test results, property size, and projected wastewater volume, our designer engineers a complete system layout. This includes tank sizing, drain field dimensions, distribution box placement, setback distances from wells and property lines, and pipes routing. We produce a detailed site plan and submit it for permit approval.

Step 3: Permitting and Approval. We file all required applications with the local health department and coordinate the permit review. No excavation begins until we hold an approved permit.

Step 4: Excavation and Installation. Our crew mobilizes backhoes, excavators, and trenchers to your site. We excavate the tank pit, trench the lateral lines, set the septic tank, install the distribution box, connect all PVC pipe and fittings, lay perforated pipe in the drain field, place stone aggregate and geotextile fabric, and install risers, access lids, and inspection ports.

Step 5: Backfill, Grading, and Final Inspection. We backfill all trenches, compact the soil, and grade the surface for proper drainage. The health department inspector conducts a final inspection and certifies the installation. We provide you with as-built drawings and a maintenance guide.

FAQs About Septic System Installation & Design

What is septic system installation and design?

Septic system installation and design is the complete process of evaluating a property’s soil, engineering an onsite wastewater treatment layout, obtaining permits, and constructing the appropriate system. It includes the septic tank, distribution box, drain field, all piping, and associated components. A licensed designer creates the plan, and a certified installer builds it.

How long does a new septic system installation take?

Most residential installations take three to five days once the permit is approved. The permitting process itself can take one to four weeks depending on your county health department’s schedule. Complex systems like mound designs or aerobic treatment units may require additional time.

When do I need a new septic system designed?

You need a new design when building on undeveloped land, replacing a failed system, expanding your home’s footprint, or decommissioning an old cesspool. Any change in wastewater volume or property use typically triggers a redesign requirement.

How much does septic system installation cost in Tennessee?

A conventional gravity-fed system typically costs between $4,000 and $8,000 for a standard residential property. Alternative systems like mound systems, aerobic treatment units, or drip irrigation setups range from $10,000 to $25,000 or more depending on site conditions and system complexity. Contact us for a detailed estimate.

Can I install a septic system on any property?

Not every lot qualifies. The soil must percolate within an acceptable range, the water table must sit deep enough below the drain field, and the property must have adequate space for required setbacks from wells, structures, and property lines. A perc test and site evaluation determine feasibility.

Does Rural Septic TN handle the permit process?

Yes. We manage every step of the permitting process, from soil testing and site plan submission to health department coordination and final inspection scheduling. You don’t have to navigate the paperwork alone.
