Septic Tank Additives: Do They Work?

Septic tank additives are marketed to supplement the bacterial activity in the septic system, but are they effective and worth the money? In this brief article brought to you by Septic Blue, we give you a quick rundown. Septic Blue is an established and insured septic company with uniformed septic specialists.

Understanding septic tank biology

Septic systems rely on a delicate balance of bacteria to treat waste and wastewater effectively. Anaerobic bacteria in the septic tank installation break down organic matter, converting solids into liquids and gases. This process reduces the volume of sludge and scum in the tank. In the drain field, aerobic bacteria further treat the effluent by consuming remaining organic matter as it percolates through the soil.

Factors that affect bacterial activity in the septic system

A professional septic tank installation involves adding the right amount of beneficial bacteria, but routine maintenance and proper usage is crucial in sustaining these diligent workhorses. Here are some threats to the bacteria to remember:

• Antibacterial soaps, bleach, and harsh chemical cleaners flushed down the drains can kill beneficial bacteria.
• Antibiotics and similar medications can also attack the bacteria in the septic system.
• Excessive water use or large amounts of waste entering the septic tank can overwhelm the bacteria, reducing their efficiency in breaking down solids.
• Very high or low temperatures can slow down bacterial activity or even kill the bacteria. Cold temperatures slow them down; high temperatures can destroy them.

What are septic tank additives?

Septic tank additives come in various forms, including powders, liquids, and dissolvable packets. They often contain enzymes, bacteria cultures, or chemical agents that claim to enhance bacterial activity, reduce odors, break down solids more effectively, and maintain a healthier septic system environment.

The debate on effectiveness

While manufacturers claim that septic tank additives can improve system performance, the scientific community and regulatory bodies like the Environmental Protection Agency (EPA) remain skeptical. Studies on the effectiveness of these additives have yielded mixed results.

Studies have shown varying degrees of effectiveness, with some additives providing minimal benefits or even causing harm to the system. Some additives may contain chemicals that can harm the natural balance of bacteria in the septic tank. Others might contribute to increased solids accumulation or interfere with the natural decomposition processes.

The EPA and other regulatory agencies caution against relying on additives as a substitute for proper septic system maintenance. They recommend regular septic tank pumping, proper waste disposal practices, and avoiding excessive water use
