Septic Systems: Essential Information

A septic system is an underground wastewater treatment structure, commonly used in areas without centralized sewer systems. It safely treats and disposes of household wastewater onsite.

How a Septic System Works

1. Wastewater Flows In: All water from toilets, showers, sinks, and appliances drains into the septic tank.

2. Separation: The tank holds wastewater long enough for solids to settle (sludge) and oil/grease to float (scum).

3. Breakdown: Bacteria in the tank break down some of the solids.

4. Effluent Release: Liquid wastewater (effluent) exits the tank into a drainfield for further treatment by soil filtration.

Key Components

• Septic Tank: A watertight container that holds and treats incoming wastewater.

• Drainfield (Leach Field): A network of perforated pipes or specialized chambers buried in shallow trenches for final treatment. One common modern option is the use of infiltrator chambers, which are open-bottomed plastic chambers that distribute effluent and promote better soil absorption. Infiltrator chambers often replace traditional gravel and pipe systems, offering easier installation, improved efficiency, and greater durability.

• Soil: Provides additional filtration, removing harmful bacteria, viruses, and nutrients.

Maintenance Tips

• Pump Regularly: Have your tank pumped every 3-5 years.

• Conserve Water: Reduce water use to prevent overloading the system.

• Dispose Properly: Don’t flush wipes, medications, or chemicals.

• Inspect Annually: Check for leaks or signs of failure.

•  Keep vehicles and heavy equipment off the drainfield to avoid compacting the soil or damaging pipes.

•  Plant only grass over and near your septic system to prevent roots from damaging components.

•  Direct roof drains, sump pumps, and surface water away from the drainfield area.

•  Fix leaky toilets and faucets promptly to avoid excess water entering the system.

• -Space out laundry loads to give your system time to treat wastewater effectively.

Signs of Septic System Problems

• Slow drains or sewage backups

• Bad odors around the tank or drainfield

• Wet, soggy soil over the drainfield

• Lush, bright green grass over the system

Why Proper Maintenance Matters

A well-maintained septic system protects your health, your property, and the environment. Proper care prevents costly repairs and groundwater contamination.
