What is a Septic System & How Does It Work?
Think of this system as your property’s underground wastewater superhero. Here’s the play-by-play:

  • Tank Time: All your home’s wastewater flows into a buried tank. Solids sink (sludge), fats float (scum), and liquid hangs in the middle.
  • Drain Field Duty: That liquid (now called effluent) trickles into a network of perforated pipes buried in gravel. Soil and bacteria act as natural filters, cleaning the water before it rejoins groundwater.
  • Microbe Magic: Helpful bacteria in the tank eat waste, breaking it down—no chemicals needed.

But here’s the kicker: This eco-friendly system only works if it’s designed and installed right. Too small? Overflows. Wrong soil? Drain field fails. That’s why our new septic tank installation starts with soil tests and local permits—no guessing.
Types of Septic Systems We Install
Not every property can use the same system—and that’s okay! We install 4 main types, tailored to your land and needs:

  1. Conventional Systems: Tank + drain field. Perfect for deep, well-draining soil. Simple and budget-friendly.
  2. Aerobic Treatment Units (ATUs): Oxygen-powered tanks that break down waste faster. Ideal for small lots or poor soil.
  3. Mound Systems: Raised drain fields built above ground. Fixes shallow soil or high water tables.
  4. Sand Filters: Extra layers of sand and gravel polish wastewater. Great for eco-sensitive areas (like near lakes).

Confused? Don’t stress. As septic systems installers near me, we test your soil, check local rules, and explain your options in plain English. No sales pitch—just the right system for your home.

Dig
Excavate the tank area and drain field. We minimize mess—promise.
Install
Set the tank, lay pipes, build the drain field. Precision matters.
Inspect
County approves, we backfill, and you’re done!

How Much Does Septic System Installation Cost?
Most systems cost 6,000–20,000. Why the range?

  • Tank size: 1,000 vs. 1,500 gallons.
  • Soil prep: Rocky? Sloped? Adds labor.
