Can you use a garbage disposal with a septic system?

You must be acquainted with that every Septic system is unique.  If one septic system is working better for one user’s kitchen then it may not work for another. Highlighting the importance of considering the specific needs and limitations of your particular Garbage Disposal System.

One can use a garbage disposal with a septic system. Manufacturers now offer garbage disposal systems specifically designed for use with septic systems. But even with these special devices, caution and safety gaudiness are advised. 

Facts and Figures

  • After extensive research and studying several systems, a 2019 study found little significant impact on the frequency of pumping needed for septic systems fitted with garbage disposals. This conclusion was drawn from the observation that food waste from disposals is largely biodegradable, thus posing negligible utility challenges.
  • In synchrony with this research, a 1998 paper from InSinkErator based on the research from the University of Wisconsin echoes a similar sentiment. It highlighted the cost-effectiveness of using a garbage disposal in homes with septic systems for both municipalities and homeowners. This illuminates the financial advantage gained by using these systems, in addition to the environmental benefits.

Understanding the Cost-Effectiveness of Garbage Disposals 

When considering the economic facet, garbage disposals, when used in residences with septic systems, have demonstrated measurable cost-effectiveness according to research by the University of Wisconsin, which is summarized in a 1998 paper by InSinkErator. This cost-effectiveness derives from decreased municipal expenses related to the management of food waste and reduced homeowners’ expenditures on septic system maintenance.

Biodegradability and Frequency of Pumping

The link between the biodegradation rate of food waste and the frequency with which septic systems are pumped is of interest. Biodegradability refers back to the potential of substances to break down and return to nature. In the case of meal waste transported using a landfill, this technique can significantly affect sewer efficiency and protection.

Operational Compatibility

Garbage disposers display remarkable effectiveness in grinding food waste, typically not causing any obstruction to the pipe between the disposer and the septic tank. However, discrepant substances like hair or candy wrappers, which are not biodegradable, are more prone to causing issues and may require more frequent pumping.

Assess More Than Food

The University of Minnesota, commissioned by InSinkErator, has presented findings indicating that garbage disposals increase both the organic loading and the chemical oxygen demand in septic systems. This, in turn, may necessitate modification in the usage of garbage disposals and increase the upkeep of septic systems. 

Mindful Garbage Disposal Use

When it comes to a home fitted with a garbage disposal appliance and septic system, homeowners should use the disposal sparingly. This will keep the waste levels manageable and may decrease the necessity for frequent pumping or other intensive maintenance tasks. 

Pumping Frequency and Routine Maintenance

As a typical guideline, septic tanks necessitate pumping every three to five years but using garbage disposal regularly could shorten this interval. Hence, garbage disposal fitted into a septic system warrants close attention and regular maintenance to ensure optimal operation and longevity.

Potential Issues with Using a Garbage Disposal with a Septic System 

Using a garbage disposal with a septic system might lead to increased waste, necessitating more frequent pumping. Getting your septic system pumped or inspected more frequently might become a routine if you decide to use a garbage disposal. 

While garbage disposers are generally effective in grinding food waste, which should not cause any blockage in the pipeline leading to the septic tank, non-food waste such as hair and candy wrappers can indeed cause issues. These non-biodegradable elements are more likely to create problems, as they can clog the pipeline. 

How do we cope with those issues?

Avoiding Non-Biodegradable Items 

Everything you put down your garbage disposal will make it smoothly to the septic tank. It may be curious to see. But it may not happen. Non-biodegradable substances such as fur and candy wrappers are the main offenders for clogging your disposal system. As a result, these materials cannot break down naturally in the tank and become stuck in the pipeline, revealing into larger issues.  

Specific Food Scraps to Steer Clear of

When it involves meal scraps, certain ones spell disaster on your rubbish disposal and septic device. Foods such as coffee grounds, pasta, bread, rice, large animal bones, fruit pits, shells or nuts, eggshells, onion layers, and stringy greens ought to be kept out of the disposal. Instead of being nicely damaged, these objects can stay within the tank, interfering with its overall performance and probably leading to malfunctions.
