Understanding Your Septic System

Knowledge s the first step to a healthy, long-lasting system.

🏠 What Is a Septic System?

A septic system is an underground wastewater treatment structure commonly used in rural areas without centralized sewer systems. It consists of a septic tank and a drain field (also called a leach field).

  • The tank separates solids from wastewater.

  • The drain field filters the liquid (effluent) back into the soil.

⚙️ How It Works

  • Wastewater from your home flows into the septic tank.

  • Solids settle to the bottom (sludge), grease and oils rise to the top (scum), and liquid stays in the middle.

  • Bacteria begin breaking down the waste.

  • The liquid (effluent) flows into the drain field for natural filtration through soil.

  • The tank separates solids from wastewater.

  • The drain field filters the liquid (effluent) back into the soil.

🔍 Common Septic System Types

  • Conventional System (most common)
  • Pressure Distribution Systems
  • At-Grade Systems
  • Holding Tanks (non-treatment, must be pumped regularly)
  • Box Mound (used where soil depth is shallow or has poor structure, or the water table is high)

We will help you determine which is right for your sight.

🛑 What Not to Flush

To protect your system and avoid costly backups, never flush:

  • Wet wipes (even “flushable” ones)

  • Feminine hygiene products

  • Grease or cooking oil

  • Harsh chemicals or bleach

  • Medications

đź§Ľ Best Practices for Maintenance

  • Pump your tank every 3–4 years

  • Don’t park or drive over your system

  • Direct downspouts and sump pumps away from the drain field

  • Use water efficiently (fix leaks, space out laundry loads)

đź§Ş Water Testing: A Vital Step

  • If you have a well, routine water testing ensures your drinking water is free of contaminants—especially important for property sales or when installing new septic systems.

đź“‹ What Happens During an Inspection?

  • Locate and uncover the tank

  • Measure scum/sludge levels

  • Check for cracks, leaks, and backups

  • Evaluate the drain field

  • Provide a detailed report and recommendations

🧠 Septic System Myths – Busted!

  • MythReality

    “If it’s working, don’t touch it.”Preventive care beats costly repairs.
    “I can flush anything if I have a garbage disposal.”Not unless you like calling us often.
