How to Properly Use a Septic System: A Complete Guide

A septic system is an important part of your home’s plumbing, especially for homes in rural areas where there’s no access to city sewer systems. It helps manage and treat wastewater from your toilets, sinks, and other drains. When used and maintained correctly, a septic system can last for many years and work efficiently. This guide will explain how septic systems work, common mistakes to avoid, and best practices to keep your system running smoothly.

What is a Septic System?

A septic system is an underground waste treatment system that handles wastewater from your home. It has two main parts: a septic tank and a drain field.

  • Septic Tank: This is a large container buried underground where wastewater from your home flows. The tank allows solids to settle at the bottom while the liquid flows out to the drain field.
  • Drain Field: This is a network of pipes buried in the ground where the liquid effluent (wastewater) from the septic tank is filtered by the soil before it is returned to the environment.

How Does a Septic System Work?

  1. Wastewater Entry: Wastewater from toilets, sinks, and other drains enters the septic tank.
  2. Separation: In the septic tank, solids settle at the bottom, forming sludge, while grease and oils float to the top, forming scum. The clear liquid in the middle flows to the drain field.
  3. Filtration: The liquid flows through the pipes in the drain field and is filtered by the soil, which helps remove harmful bacteria and chemicals.
  4. Disposal: After being filtered, the treated water slowly moves back into the soil and returns to the natural water cycle.

How to Properly Use a Septic System

Using your septic system properly can prevent problems and extend its life. Here are some simple tips to follow:

Save Water

Too much water flowing into the septic system at once can overwhelm it, leading to problems. By conserving water, you reduce the load on the septic system and help it work better.

Water-saving tips:

  • Fix leaks: A leaky faucet or running toilet wastes water. Fix them as soon as possible.
  • Use water-efficient appliances: Install low-flow toilets and faucets to reduce water use without sacrificing comfort.
  • Spread out laundry loads: Doing multiple loads of laundry in one day can overload the system. Try to space out your washing machine.

Avoid Pouring Harmful Chemicals Down the Drain

Certain chemicals can damage your septic system by killing the helpful bacteria inside the tank that break down waste. Avoid dumping harmful substances into your drains.

Things to avoid:

  • Grease and oils: Don’t pour cooking grease or oils down the drain. They can clog the system.
  • Non-degradable items: Never flush things like paper towels, wipes, or feminine hygiene products—they don’t break down in the septic tank.
  • Harsh chemicals: Drain cleaners, pesticides, and paint thinners can kill bacteria in your tank, making it less effective at treating waste.

Be Careful About What You Flush

Only flush toilet paper and waste down the toilet. Other items can cause clogs and damage the septic system.

Items to never flush:

  • Wipes: Even “flushable” wipes don’t break down properly and can clog the system.
  • Hair: Long hair can get tangled and block the pipes, causing problems.
  • Plastic items: Don’t flush things like plastic, diapers, or cigarette butts—they can cause serious blockages.

Keep Bacteria in the Septic Tank Healthy

The bacteria in your septic tank help break down waste. Maintaining a healthy balance of bacteria is essential for your system to work properly.

How to maintain healthy bacteria:

  • Use septic-safe products: Choose cleaners and detergents that are safe for septic systems.
  • Don’t overuse additives: Many commercial products claim to help your septic system, but most of the time, they aren’t necessary and can disrupt the bacteria balance.

Pump Your Septic Tank Regularly

Your septic tank needs to be pumped regularly to remove the sludge and scum that build up over time. How often you need to pump the tank depends on its size and how many people use it. Most septic tanks should be pumped every 3 to 5 years.

Signs your tank may need pumping:

  • Slow draining: If your sinks, showers, or toilets are draining slowly, it might be time to pump the tank.
  • Bad odors: If you smell sewage around your home or yard, this could mean the tank is full.
  • Backups: If water starts backing up into your home’s drains, this is a clear sign your system needs attention.

Protect Your Drain Field

The drain field is where the liquid from your septic tank is filtered by the soil. It’s important to keep it clear of anything that could damage it.

How to protect your drain field:

  • Don’t park or drive over it: Vehicles can compress the soil, making it harder for the system to filter wastewater.
  • Avoid planting trees or shrubs: The roots of plants can invade the drain field and clog the pipes.
  • Keep water away: Ensure that rainwater and runoff from your yard aren’t flooding the drain field. Too much water can overwhelm the system.

Use Your Septic System Efficiently

The more efficiently you use your septic system, the better it will perform. Spreading out water usage and avoiding overloading the system can prevent problems.

How to use your system efficiently:

  • Stagger water use: Try not to run the dishwasher, washing machine, and shower at the same time. This helps prevent overloading the system.
  • Limit garbage disposal use: While garbage disposals are convenient, they send food waste to the septic system, which can cause the tank to fill up more quickly.

Watch for Early Warning Signs of Problems

If you notice problems early, you can fix them before they turn into big, expensive issues. Keep an eye out for signs that your septic system might need attention.

Signs of problems:

  • Standing water: If you notice standing water or soggy spots around your septic tank or drain field, something might be wrong.
  • Odors: A strong sewage smell near your septic tank or drain field is a clear sign of a problem.
  • Slow drains or backups: If your drains or toilets are slow to empty or backing up, it’s time to call a professional.

Conclusion

A septic system is an important part of your home’s waste management, and taking care of it is key to making sure it works well for years. By saving water, avoiding harmful chemicals, maintaining healthy bacteria, pumping the tank regularly, and protecting your drain field, you can keep your septic system running smoothly.

If you follow these simple guidelines and keep an eye out for any early warning signs of trouble, your septic system should continue to work efficiently and without problems. If you’re ever unsure about your system or notice any issues, don’t hesitate to call a professional for help. Proper maintenance is the best way to ensure your septic system lasts a long time and works properly.
