Convenient, Continuous, Effective Septic Tank Treatment

The #1 brand of septic system treatment in Canada*, SeptoBac® offers these convenient, dissolvable, ECOLOGO certified septic-pacs. The concentrated, pre-measured pacs offer continuous treatment as billions of specialized bacteria are introduced monthly to help accelerate digestion of both organic and difficult-to-degrade septic waste. The formula also contains microbial nutrients that stimulate bacterial growth and help maintain a healthy septic system.

Convenient: Pre-measured, concentrated pacs ensure the correct amount in every dose, and pacs are economical and easy to use without the mess and inconvenience of bulk powders. No scooping or measuring is required – it's as easy as drop and flush!

Continuous: Regular monthly use ensures continuous enzyme action. SeptoBac’s special bacteria strains have greater resistance to anti-bacterial soaps and detergents than regular waste bacteria and can help replenish reduced bacterial levels in your septic tank. One pac of SeptoBac per month will maintain a constant level of bacteria in the septic system and help eliminate the need for excessive or frequent pumping. Regular septic system maintenance means less back-ups and fewer costly repairs.

Effective: The bacteria in SeptoBac septic tank treatment are specially selected by leading environmental scientists to be effective under a wide range of waste and septic system conditions. Billions of bacteria in the concentrated formula digest both organic and difficult-to-degrade septic waste such as paper, wipes, cleaning and laundry chemicals, oils and grease. SeptoBac also contains microbial nutrients to stimulate and strengthen regular bacteria levels.

+ What does SeptoBac® Septic System Treatment do?

SeptoBac® Septic System Treatment provides convenient, continuous, and effective septic treatment that maintains a healthy system. The SeptoBac formula contains billions of bacteria, specially selected by leading environmental scientists. These bacteria produce enzymes, which digest both organic and difficult-to-degrade septic waste such as paper, wipes, cleaning and laundry chemicals, oils and grease. SeptoBac special bacteria strains also have greater resistance to anti-bacterial soaps and cleaners, which can reduce the number of regular bacteria in your septic tank. SeptoBac also contains microbial nutrients to stimulate bacterial growth within the septic system. Regular use assures continuous enzyme action, reducing the risk of septic back-up and frequent pumping. Weekly use also helps to prevent offensive odours by keeping drain fields clear.

+ If the natural bacteria from waste break down the solids in my septic system, why is SeptoBac Septic System Treatment necessary?

SeptoBac septic tank treatment helps in the natural process by:

  1. Providing nutrients for the natural bacteria to grow and maintain an effective population throughout the system.
  2. SeptoBac bacteria are specially bred to break down difficult-to-degrade waste.
  3. SeptoBac bacteria are more resistant to chemicals that can kill regular bacteria.

+ How often should I use SeptoBac to treat my septic system?

For regular septic system maintenance:

  • SeptoBac Pouches – Weekly flush 1 envelope down toilet.
  • SeptoBac Dissolvable Pacs – Monthly flush 1 dissolvable pac down toilet.
  • Septo Bac 3 in 1 Formula – Monthly Pour 1/3 of bottle down any drain or toilet.

+ Which form of SeptoBac Septic System Treatment should I use if my septic system is sluggish?

For sluggish septic systems, we recommend using SeptoBac Septic System Treatment pouches and increasing treatment to 2 pouches every other day for 2 weeks, then return to the regular maintenance treatment using one SeptoBac pouch weekly.

+ Other than domestic toilets in homes and cottages, where else can I use SeptoBac?

SeptoBac products are safe for all septic systems and holding tanks including boats, RV’s, composts, cesspools, chemical toilets and outside toilets.

+ What is the difference between SeptoBac Pouches, Pacs and Liquid Triple Action Treatment Drain Care & Freshener?

Each of the SeptoBac Septic Treatments provide convenient, continuous and effective septic treatment. The pouches and dissolvable pacs contain billions of bacteria per gram of powder. These specially selected bacteria produce enzymes, which digest both organic and difficult-to-degrade septic waste and have greater resistance to anti-bacterial soaps and cleaners. SeptoBac also contains microbial nutrients to stimulate bacterial growth. Both the weekly pouch and concentrated monthly dissolvable pacs are flushed down the toilet to provide continuous septic system maintenance.

The SeptoBac liquid formula prevents costly septic back-ups by breaking down both organic and difficult-to-digest waste and contains microbial nutrients to stimulate bacterial growth. This triple action liquid formula is applied into any drain or toilet, which helps to maintain a smooth running fresh drain.

+ I just moved into a home. How do I know the size and condition of my septic tank?

We recommend having the tank inspected and pumped if needed. The company inspecting the tank should be able to tell you its’ size, age and condition.

+ How often should I call a professional to pump my septic system?

Most experts recommend pumping every 2 – 5 years. This will depend on the number of people in the household, the volume of wastewater that enters the tank, the amount of solids in the wastewater, and the size or volume of the tank.

+ How will I know if I have a problem with my septic system?

There are a number of signs indicating a problem with your septic system:

  • Odours may be noticeable.
  • A black-grey odourous liquid may accumulate at the soil surface.
  • Liquid drains slower than normal or backs up.
  • Grass over the system appears greener and soggy or may be spongy to walk on.
  • The water level in the septic tank is higher than the outlet pipe.

+ Can my septic system freeze?

Septic systems can freeze in periods of extremely cold temperature when there is little snow cover on the ground. If this happens you should call a qualified professional to defrost pipes. Never add antifreeze or salt to the tank or try to run water continuously to defrost the system.

+ What kinds of detergents are safe to use with a septic system?

It is best to use liquid detergents or concentrated detergents that don’t contain phosphates. Avoid antibacterial soaps and cleansers since they will kill off the bacteria within your septic system. Remember it is important to keep an adequate level of bacteria to ensure effective operation of your septic system.

+ Is it safe to plant over my septic system?

Trees and shrubs should be avoided due to potential damage from aggressive roots. Fruits and vegetables should also be avoided since the garden soil and/or the fruits and vegetables can become contaminated with pathogens if the system is not working properly. Meadow grasses, turf grasses, and small shallow-rooted ornamental grasses and plants are a good suggestion for covering your drain field or leaching bed; they can look nice and require little maintenance. Keep in mind not to overload your drain field with too much watering.
