Septic systems

Septic systems, otherwise known as on-site sewage disposal systems, are commonly found at homes and businesses that are located too far away to be connected to the city or town’s centralized sewer system.

The Indiana State Department of Health (ISDH) estimates that there are approximately 800,000 septic systems in use, with local health departments issuing more than 15,000 new permits per year and 6,000 permits for septic system repairs.1

Septic Tank and System Basics

Your septic system includes the tank, distribution box, and drain field (also known as a leach field). When you use your shower, sink, toilet, or washing machine, the wastewater flows into the septic tank where a complex biological process occurs to break down sludge (solids) and scum (fats, oil, and grease) in the tank and remove pathogens from the water that is pumped into the drain field by the distribution box.

Importance of Keeping Your Septic System Healthy

In addition to preventing costly repairs, proper septic tank maintenance helps to keep your family, animals, and community safe. According to researchers at Purdue University, a single failing septic system can allow more than 76,650 gallons of contaminated wastewater to enter into local ground and surface water supplies in just one year!2

Common Septic Tank Problems

Some of the most common septic system-related calls we receive are for:

  • Blockages caused by common household items like hair, foreign objects, feminine hygiene products, coffee grounds, and more!
  • Broken or collapsed baffle (the barrier between the two compartments of your septic tank).
  • Sewage backups in the bathroom, kitchen, or washing machine.
  • Strong foul odors inside the home or outside near the septic tank.

Why Not to DIY Your Septic Plumbing Repairs

Due to the hazardous nature of the waste contained and potentially emitted by your septic system, it’s always best to enlist the help of an experienced septic system plumber for regular septic system maintenance and septic tank repair services.

If you experience any of the following, call our experienced team of septic tank plumbing specialists immediately:

  • Sewage backup in sinks, showers, washing machines.
  • Strong foul odors inside or outside near the septic tank.
  • Water drains slowly from toilets, showers, and sinks.
  • Spots near the septic tank and drain field that are soggy, have standing water, or have bright green grass – more so than normal – particularly in off-season months.

Frequently Asked Questions

Septic System

  • What is a septic system in plumbing?

    A septic system is an underground wastewater treatment system that separates solids from liquids and disperses wastewater into the ground. It’s commonly used in homes but not connected to city sewers.

  • What is a septic system?

    A septic system is a private, on-site wastewater treatment system that treats sewage and wastewater, typically used in rural or suburban areas without access to municipal sewage systems.

  • How does a septic system work?

    A septic system works by collecting wastewater from your home into a septic tank, where solids settle and separate from liquids. The liquid then flows into a drain field, where it filters through the soil for natural treatment.

    A septic system should be inspected and cleaned every 3 to 5 years to ensure proper function and prevent costly repairs or replacements.
