In areas with municipal sewage systems, the technique functions adequately. But if you live in a house with a septic system, can you have a garbage disposal with a septic tank?

Food particles are added to the solids layer deposited on the bottom of your septic tank when you use trash disposal. These extra solids might overflow your tank and cause serious problems. Solid levels increase, your tank's capacity declines, and bacteria's capability to process wastewater is reduced.

From our vantage point, the easy response is no.

What Purpose Serves a Septic System?

The function of a septic system is similar to that of a sewer system. Before discharging the liquid effluents into a drain field, it accepts waste and processes it with bacteria, dissolving solids. A tank's capacity to store up to 1,000 gallons of water is only one of its numerous advantages in terms of total usability—septic tanks.

Not Advised For Waste Disposal

Sludge is solid waste that settles at the bottom of your septic tank. Bacteria have adequate time in healthy tanks to decompose organic materials and regulate sludge levels.

If you consistently run food scraps down trash disposal, you will eventually overwhelm these germs. Sludge levels increase your tank's capacity declines, and bacteria's capability to clean wastewater suffers.

Affectation on Costs

The wastewater in your house is separated from the solids and floating debris (oils and grease) by septic tanks.

Solids sink to the bottom while floating particles ascend to the top. In tanks that are in good health, bacteria have ample time to decompose organic material and maintain the level of solids.

Affectation on Costs

Additionally, regular waste disposal might increase homeowners' bills. Your septic tank will need frequent pumping and inspections if natural bacteria can't break down the contents rapidly enough.

When the cost of extra pump-outs that could be avoided is considered, the benefits of getting rid of trash don't seem that important.

These materials won't break down in your septic tank even if they go down the trash disposal. They will instead build up until a pumper removes them.

Hot Or Cold Water
