If you’re wondering how to increase bacteria in a septic tank, the answer is routine inspections, timely maintenance, and avoiding actions that offset the bacteria in the first place.
Using an additive to increase the bacteria in your septic tank is the last resort and should only be done if recommended by a septic professional. Additives may seem like bargain solutions, but they can cause problems, especially if you’re not having annual inspections and routine septic tank pumping.
Here’s why:
Septic Tank Additives Cannot Replace Routine Maintenance.
Your septic tank separates solids, grease, and oils from wastewater before it flows into the drain field. Inside the tank, both aerobic and anaerobic bacteria help clean the water by breaking down organic material.
Oils and grease rise to the top, forming a layer called scum, while heavier solids settle at the bottom and accumulate as sludge. The clarified liquid between these two layers then flows safely into the drain field.
So, even a perfectly working septic system will require septic tank pumping, usually every 3 to 5 years. Signs that the bacteria in your tank are off balance may indicate that the tank needs to be pumped. An older septic system – even 10 years old – may need to be upgraded or replaced.
When are Additives Safe for Your Septic Tank?
Septic tank additives can be inorganic compounds, organic solvents, or biological additives. Many of these are approved for septic systems, but please consult a professional before using one. (You can call us at 503-630-7802).
Inorganic additives typically contain strong acids or alkalis and can damage your septic tank’s function, causing raw sewage to flow into your drain field and clog pipes and the soil. These additives can also corrode tanks and distribution boxes!
While safe additives exist, it’s better not to increase the amount of bacteria in your septic tank.
Some ways to do this include:
- Reduce the amount of water you use – Fix leaky faucets, do laundry sporadically rather than all at once, and use water-efficient appliances. Never drain a hot tub or pool into your septic system or drain field.
- Limit what you put into the system – Don’t put fats, grease, oils, fuel, coffee grounds, eggshells, or nut shells in your septic system. Limit the use of your garbage disposal.
- Use toilet paper recommended for septic systems – Some toilet paper breaks down easier than others. Never flush wipes of any kind or feminine products.
- Don’t run chemicals down the drain – Chemicals, even those in household cleaning products, kill healthy bacteria.
- Contact a professional – If you think you need to increase the amount of bacteria in your septic tank, contact a professional like the Drain Doctor. A fast, inexpensive fix like an additive can lead to thousands in damages if what you really need is regular maintenance.
