Best Dishwasher Detergents for Your Septic Tank System?

Owning a septic system means you are free from monthly sewer bills from the municipality or the city government, but the responsibility of maintaining your wastewater treatment system rests on your shoulders. Luckily, you can simply call Septic Blue when you need septic tank cleaning, repairs, inspections, and even replacements, but it is also important that you understand how to properly care for your septic system. An important yet often overlooked part of proper care for the septic system is the type of dishwasher detergent you use.

Be Mindful of What Detergent You Use

We are all familiar with the rules of thumb associated with regular sewer systems such as not flushing nondegradable objects and refraining from tossing food particles and grease in the kitchen drain. These apply to septic systems as well. But, did you know that the type of detergent you use is also crucial? Some detergents contain chemicals that can damage your pipes and your septic system is especially sensitive to certain chemicals because of the “good bacteria” housed in the septic tank.


Septic systems lead wastewater and solid waste from your household into the septic tank where vital “good” bacteria and microbes are housed. These bacteria break down solid waste into sludge which occupies less space than the original solid waste. After some time, usually two to three years, the sludge is pumped or cleaned out by septic professionals such as Septic Blue. If the bacteria are unable to break down the solid waste, then your septic system is prone to being overwhelmed, prematurely filled, and overflowing. Therefore, antibacterial soap is a solid no-no. Use non-antibacterial soaps that will not threaten the life of vital bacteria in the system.


Phosphates are chemicals that help remove food and grime from dishes, but they are as hazardous as they are effective at their job. In fact, phosphates have been banned from laundry detergent in the United States. You should not use detergent that contains phosphate because they can be toxic for the environment. This is an especially sensitive point because septic systems are not closed systems. The phosphate will eventually be released into the drain field where it will percolate through the solid and contaminate ground water. Phosphate is also a threat to good bacteria and enzymes in the system just like anti-bacterial detergent.
