    Garbage Disposal for Septic Tanks Buying Guide

    A septic system is designed to safely digest and dispose of the human waste that comes from your home. Which type of garbage disposal should be used for a septic tank? There are two main types, continuous feed or batch feed. Here are the key factors that should be considered when buying the best garbage disposal for septic tank:


    Garbage disposals are usually divided into two categories – continuous feed garbage disposals and batch feed garbage disposal.

    Continuous feed garbage disposal will keep going until it grinds up everything inside of it from start to finish, without you having to turn it off and empty garbage out. Batch feed garbage disposal will provide you with more control. Waste can be ground once a week or even daily, but not non-stop ( as is the case of the continuous garbage disposal).


    Garbage disposals are typically described in HP (horsepower) – usually from 1/2HP to 3HP. Your garbage disposal should have power depends on the size of garbage you make in your house.

    The most commonly used garbage disposals are around 1/3 horsepower. Still, if you are looking for something more substantial, 2HP would probably suit your needs better. Unfortunately, garbage disposals with higher power usually cannot be installed under kitchen sinks without additional modifications like cutting pipes.


    They might be called quiet garbage disposal, extremely quiet garbage disposal, or very quiet garbage disposal. This is because garbage disposals can make so much noise. After all, there is something in there to grind. It could be food waste, glass, rocks – whatever you put inside of garbage disposal will have to be cut and ground by blades on garbage disposals motor.

    Also, garbage disposals can become noisy if not installed correctly or if water has got into its motor while installing. If you choose a batch feed garbage disposal with maximum HP, expect it to make more noise than continuous feed garbage disposal for a septic tank of the same power.

    What is the best type of garbage disposal for a septic tank?

    Two main types can be used for a septic system: continuous feed or batch feed. A continuous feed operates by sending waste from your home into the disposal unit through a pipe.

    Using this allows the wastewater to be continuously treated as it comes in but can cause problems if overused. This is because the septic system will not have time to process everything before it enters the drain field. A batch feed operates similarly but does not send anything into the drain field unless you press a button. This is safer for a septic tank, but it has a lower capacity than a continuous feed and is more expensive.

    Why is this the best choice for a septic tank?

    A batch feed used with a septic system allows you to have complete control over when the wastewater is sent into the drain field.

    This means that you can avoid overloading the septic system and causing damage to it while still ensuring everything is properly treated. It also ensures that your garbage disposal does not clog up or trip a circuit breaker when in use, as it only sends wastewater through when you want it to.

    What are the pros and cons of having garbage disposal?

    The garbage disposal allows you to discard food waste without having to take it outside. This means that the garbage may smell better in your kitchen since less garbage will be left on the counter or near garbage pails.

    Garbage disposals also help with cleanup time since fewer dishes and pots need to be washed by hand.

    However, garbage disposals do not solve all garbage disposal problems. For example, people often try to dispose of garbage that is too big for garbage disposals, such as chicken bones or glass containers.

    These items can become jammed in the garbage disposal and result in a messy clean-up. It is also important to make sure garbage has been chewed into small pieces before being put into garbage disposals.

    Benefits of using a garbage disposal

    – Energy efficiency: garbage disposals are much less expensive and easier than using a garbage can, picking up garbage every day.

    – Environmentally friendly: if you use a garbage disposal in your house, it means that you will not be producing garbage every day, and there will be no need to take garbage outside to the bins all the time, so this significantly reduces the negative impact on our environment.

    – Healthier lifestyle: people who do not use garbage disposal at all or do not keep their garbage disposal clean tend to have more digestive problems and stomach aches because of bacteria getting into food.
