Septic Tank Installation near Raleigh, NC | Step-by-Step Guide for Homeowners
Need a Septic Tank Installed Near Raleigh? Here’s What to Expect Step-by-Step
If you're reading this, you're probably staring at your backyard wondering, “What in the world have I gotten myself into?”
Maybe your current septic system is failing. Maybe you’re building a new home and this is one more item on the growing to-do list. Either way, you’re not alone. We talk to Wake County homeowners every week who are overwhelmed by permits, costs, contractors, and just trying to get it done right.
We get it — this isn’t something you do every day. But we do. And while we don’t believe in bragging, we do believe in sharing what we’ve learned, so you don’t end up stressed, stuck, or surprised.
At Absolute Septic LLC, based out of Smithfield, we’ve helped homeowners across Wake and Johnston Counties navigate septic installations with confidence. Let’s walk through exactly what to expect — no fluff, no sales pitch. Just answers.
1. Why You’re Here: The Real Stress Behind Septic Installation
Septic work is one of those projects no one dreams about, but when you need it, you need it done right. You might be dealing with:
A strong odor in the yard
Slow drains in the house
A soggy patch of grass that never dries
Or you're building on land without access to city sewer
Whatever the reason, this isn’t a small job. It affects your home’s value, your health, and your peace of mind. And it’s not cheap — so mistakes are costly. That’s why understanding the steps ahead of time makes all the difference.
2. First Things First: Do You Actually Need a Septic Tank?
Not every property needs a new system. If you’re replacing an old one, a full system replacement may not be required. In some cases, it’s just the drain field or tank that needs updating. A licensed septic contractor (like us) can walk your property and tell you what’s really needed.
If it’s new construction, and your home isn’t connected to the city sewer system, then yes — you’ll need a septic system from the ground up.
3. Permits and Paperwork in Wake County
Before a shovel hits the dirt, Wake County Environmental Services has to sign off. That means:
Site evaluation application
Soil and perk test
Septic system design plan
System permit
We help homeowners handle all of this because the paperwork can feel endless. But here’s the thing: if the permit process isn’t followed, you risk fines, construction delays, or even being told to dig everything back up.
4. Choosing the Right Septic System for Your Property
There’s no “one-size-fits-all” when it comes to septic. The right system depends on your soil type, property slope, home size, water usage, and more.
Here are the two main systems Raleigh homeowners usually choose from:
Gravity-fed systems – Simple, lower cost, ideal if your soil drains well and your site has natural slope.
Pressure or pump systems – Needed when gravity won’t do the trick (flat land or poor soil). Slightly more costly but more flexible.
We’ll help you figure out which one makes the most sense for your property and budget.
5. The Site Evaluation: What Inspectors Are Looking For
A Wake County inspector (or soil scientist) will come out and test your soil. They’ll check:
How quickly water drains (percolation)
How deep the water table is
Slope of the land
Distance from wells, water bodies, or structures
This tells us whether we can install a basic system or need something more advanced. It’s one of the most important steps — skip it, and you could end up with a failed system before year one.
6. Getting on the Schedule: What Impacts Your Start Date
This part surprises folks — once the paperwork is in and the plan is approved, you might still be 1–4 weeks from installation. Why?
Inspector backlog
Weather delays
Equipment availability
Site prep (clearing trees, grading, etc.)
We keep you in the loop the entire time, so you're not left wondering when things are happening. Trust us: knowing ahead of time keeps frustration low.
7. The Installation Process, Broken Down
Here’s what happens once we roll up:
Site prep – Clearing, marking tank and drain field areas
Excavation – Digging out the tank and trenches for the drain field
Tank & pipe installation – Placing the tank, laying pipes, and connecting everything properly
System inspection – A county inspector confirms it meets code
Backfill and grading – We cover everything up and smooth out the land
Final walkthrough – We explain how the system works, answer questions, and review maintenance tips
Most installations take 2–4 days, weather permitting.
8. What to Expect After the Work Is Done
Once the dirt settles (literally), you’ll want to:
Avoid parking or driving over the tank or drain field
Only flush toilet paper and natural waste
Get it pumped every 3–5 years
Keep an eye out for soft spots or slow drains
We also offer follow-up maintenance reminders and support for any questions after install. You’re not left hanging.
9. How to Keep Your New Septic System Running Smoothly
Think of your septic system like your car. It works well when taken care of — but can turn into a disaster if ignored.
Here’s what we recommend:
Don’t use your toilet as a trash can. No wipes, grease, or harsh chemicals.
Space out laundry loads. Too much water at once can overwhelm the system.
Use septic-safe cleaning products. Bleach-heavy cleaners can kill the good bacteria that break down waste.
Pump it regularly. Don’t wait until there’s a problem.
10. Questions to Ask Any Septic Contractor Before You Hire Them
Not all contractors are created equal. Here’s what you should ask:
Are you licensed and insured for Wake/Johnston Counties?
How many systems like mine have you installed?
Will you handle the permits?
Can you provide references or local reviews?
What’s included in your quote — and what’s not?
You’re trusting someone to literally build the foundation of your home’s wastewater system. Don’t be afraid to ask hard questions.
11. Common Pitfalls (and How We Help You Avoid Them)

Tanks installed too close to water lines
