This article contains our conclusions to the septic tank pumping schedule guideline. We explain why a septic tank needs to be pumped regularly, how septic tanks are cleaned, how much it costs to pump a septic tank, how to inspect and clean septic tanks safely, what is septic tank effluent retention time, how to measure septic tank scum and sludge levels, and other septic tank maintenance advice for homeowners.
We point to the role played in septic system life & pumping frequency when a food waste grinder is connected to the system, and when septic treatments or additives are used. We give more information about how often septic tanks should be pumped.

Garbage Disposers and Grinders Effects on Septic Systems
Garbage grinders impose an additional solids load on the system. Solids must be removed periodically to prevent them from entering the soil absorption field. If a garbage disposer or food waste grinder is installed in your building you may need to increase the frequency of septic tank pumpout/cleanout.
Review Garbage Grinders and garbage disposal units - effects on septic systems for details.
Septic tank additives
Biological and chemical additives are not needed to aid or accelerate decomposition in conventional residential septic systems.
Products such as yeast, "septic helper" or "septic un-clog chemicals" and the use of additives in septic tanks to reduce the sludge volume or substitute for pumping is not recommended. In fact, relying on additives rather than conventional tank pumping may result in failure of the septic system.
Such septic treatments are illegal in some jurisdictions (and throughout Canada) because they may are not only of marginal effectiveness but also they may contaminate the local groundwater.
What about adding yeast to the septic tank?
Really? "Yeast" which some of our clients like to toss into their septic tank is not helpful and may actually speed drain field failure by keeping the septic treatment tank contents in an agitated state.
Be sure to review details about this topic at Septic System Additives and "Helpers".
How Quickly Does A Septic System Fail?
The life of a septic system depends on the following factors:
So provided you've addressed these factors in septic system life, how long can you expect a septic system to last before costly repairs to the septic tank or septic drain field are required?
Septic systems (tank and absorption system, or onsite wastewater disposal systems) will not fail immediately if they are not pumped. However, an un-maintained septic tank is no longer protecting the soil absorption field from solids. Continued neglect shortens the drain field life and may result in system failure and even require complete replacement of the soil absorption field. In some cases, site limitations may make replacement of the absorption field impossible - at least impossible using a conventional drainfield design. Alternative designs are available to solve these problems.
The septic tank is only one part of an on-site wastewater system. It is designed to remove solids prior to the effluent entering the soil absorption field, provide for the filtration, digestion of a portion of those solids, and storage of the remaining solids. Taking care of the septic tank will, however, extend the life of the costly second half of the onsite wastewater treatment system - the absorption system, leach field, or drainfield.

If you have just moved into a home with a septic system
If you've just moved into a home with a septic tank you may not know the size of the septic tank, its maintenance history, or even where the septic tank is. In this case, you should have the tank pumped and inspected. The company pumping the tank will tell you its size, age, and condition.
