How Doing Laundry Affects Your Septic System

The Impacts of Laundry on Septic Systems including ATUs

As a homeowner with a septic system, you may not always consider how your everyday habits impact its health and longevity. One area that often gets overlooked is laundry. How you manage your laundry can significantly influence your septic system's performance. In this blog post, we’ll discuss how laundry habits affect your septic system, especially in the context of modern wastewater management changes, and offer tips to prevent costly issues. Additionally, we’ll explore the growing trend of eliminating grey water systems, which puts even more strain on septic systems, as well as the unique maintenance needs of newer systems like Aerobic Treatment Units (ATUs).

Doing Laundry with a Septic System: What You Need to Know

When you do laundry, the water from your washer is emptied into the septic tank, where it mixes with other household wastewater. The septic system relies on a delicate balance of bacteria to break down and decompose this waste. Solids settle at the bottom of the tank, forming sludge, while the liquid portion (effluent) flows into the drain field for further treatment.

However, laundry practices can disrupt this balance. Overloading your system with water or using harsh detergents can overwhelm the septic tank, making it difficult to properly treat wastewater. This can lead to a buildup of solids as well as scum from fabric softeners, clogging the system, and potentially causing backups into your home or flooding your yard with contaminated wastewater.

The End of Grey Water Systems: What It Means for Your Septic Tank

In the past, many homes had grey water systems that diverted wastewater from sinks, showers, and washing machines away from the septic tank. However, as environmental regulations evolve, many areas are phasing out grey water systems, requiring all wastewater to be processed by the septic system. This shift places additional stress on septic tanks, which now must handle larger volumes of water and more waste than they were originally designed for.

With grey water systems being eliminated, it becomes even more critical to adopt septic-friendly laundry practices to avoid overburdening your system.

Common Laundry Practices That Can Cause Septic Problems

Several common laundry habits can negatively impact your septic system. Here are some key areas to watch out for:

Using Too Much Laundry Detergent: Excessive detergent use or use of strong chlorine bleach can harm the bacterial colonies in your septic tank, which are essential for breaking down waste. Many laundry detergents contain harsh chemicals like phosphates, surfactants, and especially bleaching agents that can disrupt the natural balance in the tank, leading to a buildup of solids and foam that can clog the system.

To protect your septic system, it’s important to use only the recommended amount of detergent and opt for septic-safe, low-phosphate products whenever possible.

Doing Large Quantities of Laundry

It might be tempting to dedicate a full day to catching up on laundry, but doing multiple loads one after the other can flood your septic system with too much water at once. This can disturb the natural separation of solids and liquids in the tank, leading to blockages and potential system failure.

A better approach is to spread out your laundry loads throughout the week, allowing your septic system time to recover between uses. Remember, your septic system has to allow the liquid to filter into the soil and that takes time that too much laundry doesn’t allow.

Neglecting Lint Filters

Clogged lint filters in your washing machine can cause problems for your septic system. Lint made of synthetic fibers doesn’t break down easily and can clog your drain field, leading to increased maintenance needs.

Regularly cleaning your washer’s lint filter can help prevent this issue.

The Added Complexity of ATUs: What You Should Know

In addition to traditional septic systems, newer technologies like Aerobic Treatment Units (ATUs) are becoming more common. While ATUs offer more efficient wastewater treatment by introducing oxygen into the process, they come with their own set of challenges. Unlike traditional septic systems, ATUs require more frequent inspections and maintenance—typically every six months.

ATUs have more complex components, such as air pumps, filters, and disinfection units, that need regular attention. Ignoring maintenance on an ATU can lead to costly repairs or even system failure. For homeowners with ATUs, it’s crucial to stay on top of the recommended service schedule, especially after a busy summer or ahead of the holiday season when water usage tends to spike.

How to Identify Signs of Septic Issues

To avoid laundry-related septic problems, it’s essential to monitor your system for signs of trouble. Warning signs of a failing septic system include:

  • Slow-draining sinks and showers: If your drains are sluggish, it could indicate a clog in the system.
  • Strong sewage odors: Foul smells in or around your home may signal a septic issue.
  • Standing water in the yard: Pooling water near your drain field is a red flag that your system isn't functioning properly.
  • Gurgling sounds from toilets and drains: This could be a sign of a backup or blockage in the system.

If you notice any of these symptoms, contact a professional right away to inspect your septic system and perform any necessary repairs.

Regular Pumping: The Key to a Healthy Septic System

Whether you have a traditional septic tank or a more modern ATU, regular pumping is crucial to keeping your system running smoothly. Most systems should be pumped every few years, but with many areas eliminating separate grey water systems and the added strain of increased household water use, more frequent pumping may be necessary.

Routine pumping and inspections help prevent backups, protect your property from damage, and extend the life of your septic system. It’s an investment in the long-term health of your home and the environment.

Conclusion

Your laundry habits play a significant role in the health of your septic system, especially as more wastewater is directed into the tank due to the elimination of grey water systems. Whether you have a traditional septic system or an ATU, proper maintenance is essential to avoid costly repairs and ensure smooth operation. By being mindful of your detergent use, spreading out laundry loads, and staying on top of regular maintenance, you can protect your septic system and keep it running efficiently for years to come.
