What is a Septic tank?

The septic tank serves as a settling basin where solids accumulate and gradually get broken down by bacterial action.

Some of the solid waste is actually liquefied by this "natural bacterial decomposition," however the rest of the waste accumulates in the bottom as a layer of sludge. Additionally, a small percentage of this waste (mostly fats and oils) float to the top of the tank to form a layer of semi-solid scum.

How Do They Work?

The population living in metropolitan areas (who have never had the pleasure of maintaining a septic system, or who have never experienced waddling in their leach-field, or even had the experience of pumping out their systems) simply flush their toilets and "away go troubles down the drain."

Those of us living in more rural areas have been forced to learn about the maintenance and working of the sewerage treatment facility attached to our home, "the septic system." Usually a septic tank is connected to a drainage field or seepage pit of some kind. If properly maintained, a well-designed system will last almost indefinitely. However, if it is neglected for too long a time, it can back up and clog the drainage field. This neglect can result in an expensive excavation and even a replacement of the drainpipes that could cost thousands of dollars.




It is important to get the septic tank cleaned before the sludge level gets high enough so that any of the solid material at the bottom, or the semi-solid scum at the top can flow out into the drainage field. This will quickly clog the drainage pipes and the soil into which they drain. If this happens the only cure would be to dig up and replace the entire drainage field.

Make certain there is live bacteria in your system at all times. The bacteria’s job is to digest all organic waste mailer in the system. If there is no bacteria in your system it will simply act as a holding tank for your waste. It becomes full, and natural digestion will not occur. That is when the system backs up.

Bacteria are killed off or overrun because of:

· excessive quantities of detergents, laundry waste, bleach, household chemicals, and caustic drain openers.

· garbage disposal grinds which substantially increase the accumulation of solids.

· disposal of items not biodegradable in the system (plastics etc.).

· disposal of excessive amounts of grease and fats, which are biodegradable but need particular types of bacteria to digest them.

· disposal of cigarette butts, sanitary napkins which are also biodegradable but are not readily decomposable.

· too many people using a smaller/inadequate or failing system.


On a monthly basis you should add enzymes and bacteria to your system.  That's what our product SEP-TEKŪ is. A blend of highly potent enzymes  and bacteria that act with the bacteria in your system to implement that rate of fermentation, thus keeping your system “working” and free-flowing.
