What Are The Laundry Detergents That Can Be Used In A Septic System?
Laundry detergents play a significant role in maintaining the health and functionality of septic tank systems. If you live in a home with a septic system, choosing the right laundry detergent is essential to avoid damaging the system or harming the beneficial bacteria within it. This guide will cover the types of detergents that are safest for septic tanks, explore what to look for when selecting a septic-safe detergent, and provide recommendations for the best detergents for septic systems.
Why Choosing the Right Laundry Detergent Matters for Septic Systems
Septic systems rely on a delicate balance of bacteria to break down and process waste. Many conventional laundry detergents contain harsh chemicals, synthetic fragrances, and other additives that can harm these beneficial bacteria. When this balance is disrupted, it can lead to issues like clogs, slow drainage, or even the need for costly repairs. Using septic-safe laundry detergents helps ensure that the bacteria in your system remain active and that the septic system continues to function efficiently.
Key Features to Look for in Septic-Safe Laundry Detergents
Before selecting a detergent for your home’s septic system, it’s crucial to understand what makes a detergent safe for septic use. Here are some features to consider when choosing the best detergents for septic systems.
1. Low Phosphates
Phosphates are chemicals commonly used in detergents to improve cleaning power, especially in hard water. However, high phosphate levels can lead to an overgrowth of algae, which can clog septic systems and pollute nearby water sources. Look for detergents labeled as “low-phosphate” or “phosphate-free” to protect your septic system.
2. Biodegradable Ingredients
Biodegradable detergents break down more easily in the environment, making them less likely to accumulate in the septic tank. Detergents with biodegradable formulas are also less harmful to the beneficial bacteria within the tank, helping to keep the system functioning efficiently.
3. Low or No Surfactants
Surfactants are chemicals that help remove dirt and stains from fabric, but they can be harsh on the environment and septic systems. High levels of surfactants can harm septic bacteria, so opt for detergents with “low-sudsing” or “low-surfactant” labels.
4. No Antibacterial or Disinfecting Agents
Antibacterial ingredients in detergents are harmful to septic systems. These additives can kill off the good bacteria in the septic tank, hindering its waste-decomposition abilities. Choose detergents without antibacterial properties to maintain a balanced bacterial environment.
5. Eco-Friendly Labels
Labels like “Septic-Safe,” “Eco-Friendly,” or “Environmentally Safe” can indicate that a detergent is less likely to harm your septic system. However, it’s still essential to review the ingredient list to confirm it meets the necessary criteria.

Additional Tips for Using Laundry Detergent in a Septic System
Even when you’re using a septic-safe laundry detergent, there are additional steps you can take to ensure your septic system remains in optimal condition.
Use the Right Amount of Detergent
Using too much detergent, even if it’s septic-safe, can overwhelm the system. Excess suds can increase the risk of clogging, so stick to the recommended amount on the detergent label. When in doubt, use less rather than more.
Limit the Number of Loads Per Day
Running multiple loads of laundry in a single day can strain the septic system, as it forces the tank to process more water than it can handle efficiently. Spread your laundry loads throughout the week to avoid overloading the system.
Avoid Liquid Fabric Softeners
Liquid fabric softeners can contain chemicals that harm the bacteria in a septic tank. Instead, use dryer balls or white vinegar as a natural fabric softener.
Choose Cold Water Washing
Washing clothes in cold water reduces the energy used and minimizes the risk of disrupting the septic system’s bacterial balance. Hot water can kill some of the bacteria essential for breaking down waste in the tank, so opt for cold or warm water whenever possible.
Choosing the Best Detergents for Septic Systems
Keeping your septic system in good shape requires more than regular pumping and maintenance—it also involves selecting products that won’t disrupt its natural balance. By choosing laundry detergents with biodegradable, phosphate-free, and eco-friendly ingredients, you can protect your septic tank from unnecessary wear and tear. Brands like Seventh Generation, Mrs. Meyer’s, and ECOS provide some of the best detergents for septic systems, offering a balance of effective cleaning and environmental safety. Alternatively, a simple homemade detergent can be an economical and septic-safe solution.
Ultimately, safeguarding your septic tank is a commitment that pays off in the long run, as it helps avoid costly repairs and keeps the system running smoothly. By following these guidelines and choosing septic-safe detergents, you can enjoy clean laundry and a healthy, efficient septic system for years to come.
