What Homeowners Need to Know About Septic Tanks

If your home isn’t connected to a municipal sewer system, chances are you rely on a septic tank. Whether you’re building a new home in rural Michigan or maintaining an older property elsewhere in the country, understanding how your septic system works—and how to care for it—is essential to keeping things flowing smoothly.

🏡 What Is a Septic Tank?

A septic tank is an underground system that treats and disposes of household wastewater. It’s commonly used in rural areas or homes that aren’t connected to city sewer lines.

Your septic system handles everything that goes down your drains—from toilets and showers to dishwashers and washing machines. It separates solids from liquids, breaks down waste, and safely disperses treated water into the ground.

⚙️ How Does a Septic System Work?

Here’s a simplified breakdown of the process:

1. Wastewater flows into the tank from your home’s plumbing.
2. Solids settle at the bottom, forming sludge, while oils and grease float to the top as scum.
3. Bacteria in the tank break down organic matter naturally.
4. Liquid effluent flows out into a drain field (also called a leach field), where it’s filtered through soil.

If everything’s working properly, it’s a quiet, odorless process. But without regular maintenance, problems can quickly arise.

🧰 Routine Septic Maintenance Tips

To keep your system healthy and avoid costly repairs, follow these basic maintenance guidelines:

• Pump your tank every 3–5 years (frequency depends on household size and usage).
• Avoid flushing non-biodegradable items like wipes, feminine products, or paper towels.
• Use water efficiently to reduce strain on the system.
• Keep heavy vehicles off the drain field to prevent damage.
• Watch for warning signs like slow drains, odors, or soggy ground near the tank.
