The Septic System of Kitchen Room

Urban areas in many countries do not have a public sewer system. Here people depend on individual septic tanks to handle waste from their bathrooms, toilets, and kitchens.

The 2011 Indian census showed that 30 million urban households (38 percent of all homes in towns and cities) have septic tanks. By 2018, estimates say this will rise to about 148 million homes. In North America, approximately 25 percent of the population relies on septic tanks.

It is vital to know how a septic tank works in order to choose the top rated garbage disposal. A septic tank system usually consists of two chambers. Waste and water enter the first chamber of the tank where solids settle on the bottom.

Scum such as oil and grease float to the top. The settled solids are decomposed using bacteria. The remaining liquid flows into the second chamber, where more settlement and treatment happens. This cleaner waste liquid flows into a septic drain field. Here soil and gravel filter out any remaining waste.

This cleaner waste liquid flows into a septic drain field. Here soil and gravel filter out any remaining waste. You must pump out the solids from a septic tank now and then. An electric garbage disposal works by shredding food waste and mixing it with water. It then passed through pipes into a septic tank or in some cases directly into a city’s main sewage system.

Before buying a garbage disposal, it is vital to know if your septic tank is big enough to handle the increased volume of wastewater the unit will produce. It is worth asking a building inspector or other qualified person. In general, if a home’s septic tank already deals with a washing machine or dishwasher as well as the toilets and sinks then it is more likely to be able to handle a garbage disposal.

Always check if local authorities allow you to install a garbage disposal if your home connects to a public sewage system. You might need to get a permit.

Benefits of A Garbage Disposal

Why choose a home garbage disposal over a trash can to get rid of food waste?

Better Health

Most people think of the toilet as the most contaminated part of the house. In fact, a kitchen sink contains 100,000 times more germs than a bathroom or lavatory. The kitchen creates more bacteria than any other room in the home. These germs can spread through a household like wildfire.

One single bacteria cell can become more than 8 million cells in less than 24 hours! As few as 10 bacteria can make people sick.

Instead of hanging around in the kitchen trash can, on the street attracting flies or even stuck in the sink pipes a food waste disposer grinds up the waste and flushes it away in a matter of seconds.

Environmentally Friendly

Food scraps make up to 25% of household trash. This normally ends up rotting in landfills creating methane gas, a greenhouse gas harmful to the earth’s atmosphere.

A garbage disposal reduces landfills by grinding up food waste so that it can pass into septic tanks or through the normal sewer system to wastewater plants. Here, it turns into fertilizers.

Food waste disposers make a very important contribution to the environment and most people are unaware of what a wise and sustainable choice they are making when they put their food ‘down the drain’’’, according to the Association of Home Appliance Manufacturers.

A Clean Kitchen

After cooking the family meal, most people’s kitchens are a mess. Cleaning up is quicker and easier when you can put leftover food straight into a garbage disposal. Just turn on the disposal unit and cold-water tap and away it goes! This also prevents smells.

Simple to Use

​Modern garbage disposals are very easy to use. Just flick a switch near the sink to turn them on and off. They are also quiet and simple to clean. Installing garbage disposals is also easy if you have good plumbing and the right septic tank.

Top Features of Food Waste Disposer

Before going to buy garbage disposal or looking at prices, it is important to consider the features of garbage disposals. Here is a list of the most important things you should look for in deciding what is the best and cheap garbage disposal.

Auto Reverse Function

This is also known as anti-jamming. It helps reduce the number of times hard materials or sticky waste becomes stuck in the grinder.The auto-reverse system will automatically make the unit go into reverse when it detects a blockage. This increases the torque, or power, and can break even the toughest of jams.This is manual in older garbage disposals. Some garbage disposals also have a ‘’jaminator’’ feature which means the impellers move back and forth (or oscillate) as the unit grinds to help prevent blockages.

Horsepower Ratings

The amount of waste a garbage disposal can handle depends upon the power of its motor. Units usually come in one of four power sizes:

1 and above Horsepower

This is the most powerful motor used in garbage disposals. It offers the most grinding capacity and speed. It will grind hard waste, such as bones and hard vegetable matter (e.g. corn and carrots), more finely and quicker than smaller motors. This size unit is best for bigger families.

Check out 1 HP Garbage Disposal:

3/4 Horsepower

This offers slightly less grinding power and capacity but can cope with the food waste of 4-6 member families.

Check out 3/4 HP Garbage Disposal:

1/2 Horsepower

This garbage disposal can grind soft waste but not hard waste such as chicken bones. Any hard waste will jam in the unit. It is most suitable for one or two person households.

Check out 1/2 HP Garbage Disposal:

1/3 Horsepower

This is the smallest motor available on the more basic garbage disposals. It is suitable only for soft foods such as vegetables. These models can jam quite frequently and have only a limited use.

Stainless Steel Grinding Chamber

The grinding chamber shreds the waste before it goes into the drain. Inside the chamber are impellers mounted on a spinning plate. These spinning lugs force food waste against a stationary grind ring, thus tearing them into small pieces. The best garbage disposals have stainless steel components in their grinding chambers, as well as the chamber itself. This means the chambers are resistant to rust, are easier to clean and last longer.

Quick Neck Mounting

This feature allows the buyer to connect the garbage disposal into the sink simply and quickly. The owner can do this himself with the light, lower horse-powered units.​One horsepower and above garbage disposals are heavier, between 15 and 30 pounds, and will need two people to install.

Electric Cord

When buying a garbage disposal check whether it come with an electric power cord. Such units plug straight into an electrical outlet.


The average warranty on a garbage disposal can be between 1 and 7 years. Some manufacturers offer up to ten years. Others offer lifetime free in-home mechanical replacement and labour warranties.​The more comprehensive and longer a warranty is, the more confidence the manufacturer has in the product.

Types of Garbage Disposals

Garbage disposal units come in one of two types: Continuous feed models and Batch feed models. The continuous feed models allow you to keep on adding food waste while the unit is running. Batch feed models require you to put the waste in the disposal, cover the opening with a stopper and then turn it on.

Batch feed and continuous feed garbage disposals grind and dispose of waste equally well. Both are just as efficient and available with the same horsepower and with the same types of grinding chambers. However, there are advantages and disadvantages to both types. This guide should help you determine which is best for you.

Continuous Feed Garbage Disposals


  • Continuous feed garbage disposals are the easiest to use, making them the most popular type of garbage disposal units. You put food waste in the sink and turn the unit on with a flick of the switch.
  • Once the garbage disposal is on you can simply keep adding waste. This means a quicker cleaning the kitchen is faster, especially if you have a lot of waste.
  • Continuous feed models need a minimal amount of maintenance and cleaning them is easy.
  • Modern models have multiple grinding chambers, which greatly reduces the number of jams.
  • These garbage disposals are generally cheaper than batch feed models.


  • Users put waste into an always-open filler neck in continuous feed models. This means there is always a risk that bits of waste may shoot out or objects such as spoons fall in while the unit is running. This latter can seriously damage a waste garbage disposal. Look out for brands that come with a splash guard to stop this from happening.
  • An open neck also means homes with small children need to make sure no little hands are stuck into the disposal’s opening.
  • Not all continuous feed models come with a power cord. You may have to buy one separately or pay to have the unit hardwired into the kitchen.

Batch Feed Garbage Disposals


  • Batch feed models are safer than continuous models. Once owners put the waste in, they must put a cover over the garbage disposal’s opening. This stopper triggers the switch to turn the unit on. It stops small children from putting their hands in the garbage disposal while it is grinding. It also stops objects such as cutlery from accidentally falling in and destroying the grinder mechanism.
  • Nearly all batch feed models come with a power cord. This means easy installation, which most homeowners can do themselves. There is no need for costly professional plumbers.


  • Filling the disposal unit first and then putting in the stopper to turn it on means the batch model is slower and less convenient. This is especially so if you have a lot of food waste. The disposal unit shreds garbage bit by bit.
  • There is a temptation to wait until a batch feed garbage disposal is full of waste before turning it on. This can create health hazards with rotting food breeding bacteria and attracting insects.

How to choose a Garbage Disposal?

Deciding what is the best garbage disposal can be difficult. It is not just about price. After all, the most expensive do not always mean the best and a cheap garbage disposal might be perfect for your home. Factors to look at include how often owners will use it and the size of families.

Below is a list of essential things to look at before making your purchase of the best garbage disposal unit.


Power and Capacity

A good garbage disposal will handle normal kitchen waste without any problems. However, the amount and type of waste you need to get rid of will determine what size garbage disposal is best for you.

The fewer the number of people in the home, the smaller and cheaper the garbage disposal needed. An apartment with two people will only need a 1/2 Horsepower (HP) or even a 1/3 HP unit if it is not used very often. A unit such as the Waste King 9930 Legend Series 1/2 HP Continuous Feed Operation Garbage Disposer can easily cope with large amounts of food left on plates.

Garbage disposal makers recommended a bigger size for family homes where members use the garbage disposal a lot. Units such the InSinkErator Evolution Septic Assist 3/4 HP Household Garbage Disposer or the Waste King Legend Series 3/4 HP Continuous Feed Operation Garbage Disposer – (L-3300) can both handle more and tougher waste such as chicken bones. They jam less and are stronger, so if items such as cutlery are accidentally dropped into them, they are less likely to break.

For bigger homes with large families of more than four people, a 1 HP garbage disposal is best.

Units such as the InSinkErator Evolution Excel 1.0 HP Household food waste disposer or the Waste King 9980 Legend Series 1 HP Continuous Feed Operation Garbage Disposer can easily cope with frequent use and the toughest food waste.


Batch Feed vs Continuous Feed

Continuous feed garbage disposals are the most popular. They save time and are easier to use. Two of the best examples of these are the Waste King Legend Series 1.0-Horsepower Continuous-Feed Garbage Disposal (L-8000) and the Waste King Legend Series 1/2 HP Continuous Feed Operation Garbage Disposal – (L-2600). You put waste into the sink, and it starts grinding. If convenience is what you want, then a continuous feed garbage disposal is right for you.

Batch feed garbage disposers, on the other hand, are safer. The cover over the grinder entrance hole reduces the chance of injury and breakdown through cutlery and other items accidently falling in.

Some of the safest on the market include the Waste King 9900TC Legend Series 3/4 HP Batch Feed Operation Garbage Disposer and the Waste King L-5000TC Legend Series 3/4 HP Batch Feed Operation Garbage Disposer.


The Grinding Stage

To be effective a garbage disposal unit must grind up waste small enough so it does not block sewage pipes or harm septic tanks. Different brands and models of the best garbage disposal units have different numbers of grinding stages. Garbage disposal manufacturers generally offer one to three grinding stages in their units.

The most common and cheapest garbage disposals use just one stage during the grinding process. This can limit the unit’s ability to grind waste into small bits and the type of waste it can handle. A lot of water is also necessary to flush the waste through sewage pipes. However, systems such as the Waste King A1SPC Knight 1.0 Horsepower Garbage Disposal highlight the fact they only have one stage. Waste King claim no multi-stage chambers are needed and the toughest waste is pulverised in one go.

Stage two grinders do the same job as stage one units but then further liquefy the waste in the second stage. This helps prevent any blockages. Two stage units such as the InSinkErator Evolution Septic Assist 3/4 HP Household Garbage Disposer and the InSinkErator Evolution Essential 3/4 HP Household Garbage Disposer can handle tougher waste and use less water.

Garbage disposals with three stage grinders such as the InSinkErator Evolution Excel 1.0 HP Household Garbage Disposer break down waste even further and can handle some of the toughest food waste there is. These units will do both stages 1 and 2 and then further reduce the liquefied waste. Manufacturers of 3 stage models claim they will even cut grains of rice into smaller pieces.


Noise and Vibration

The best garbage disposal units on the market today make much less noise and vibrations than before. There are two main causes of noise and vibration. The main one is the connection between the unit and the kitchen countertop or sink. The second is the unit itself.

The best garbage disposals reduce noise by having good mounting systems, which minimize the vibration from the unit to the sink.

As well as the mounting, insulation on the unit is also key to reducing noise. Features to look out for include insulation around moving parts, anti-vibration tailpipes or sink mounts and sink baffles. The Waste King A1SPC Knight 1.0 Horsepower Garbage Disposal uses the same material as soundproof music studios.

Features such as a nylon, insulated grinding chamber, like those produced by WasteKing, mean a quieter garbage disposal. Alternatively, the InSinkErator Evolution Excel series and the InSinkErator Evolution Essential 3/4 HP Household Garbage Disposer have ‘’Sound Seal’’ technology which makes puts them amongst the quietest garbage disposals on the market.

If you have an excessively noisy unit, it is probably because the garbage disposal is not working due to worn out parts or damage through misuse.


The Mounting

The mounting connects a garbage disposal system to a sink or kitchen counter. Manufacturers use slightly different mounting types. They should be easy and quick to install.

InSinkErator and Waste King offer two of the best mounting types.

InSinkErator’s Quick-Lock mounting system comes with all its latest ‘’Evolution Series’’ models and also fits its ‘’Badger series’’ models. The mounting is made of stainless steel and as its name suggest is easy to fit new or to replace a garbage disposal.

Waste King has two type of garbage disposal mounting systems. One is the 3 bolt mounting system with stainless components, which the last longer. The Waste King 9930 Legend Series 1/2 HP Continuous Feed Operation Garbage Disposer has these features.

The second is the EZ mount system made of plastic and aluminium.

The Waste King Legend Series 3/4 HP Continuous Feed Operation Garbage Disposer – (L-3200) uses this and has the advantage of including an easy to clean removable splash guard. The 3 bolt system does not have a splash guard.



The best garbage disposals are the ones that last a long time. These units have rust proof stainless steel grinding chambers and components. The InSinkErator Evolution Excel 1.0 HP Household Garbage Disposer has a 40 oz. Stainless steel grinds chamber with three grind stages and an automatic jam sensor.

Anti-jamming and automatic reverse systems are also very important in ensuring the best garbage disposals stand the test of time. The InSinkErator Evolution Excel 1.0 HP Household Garbage Disposer system detects jams and automatically puts the grinders in reverse to unblock the unit without the user having to do anything.



The top garbage disposals come with a clear instruction manual and all the parts needed to install it. Ideally a buyer should be able to install it himself or with the minimum of help. Hiring a professional plumber can be expensive.



Before buying a garbage waste disposal, you need to know if it will fit in your kitchen. Measure the space under the sink before making a decision. A garbage disposal’s size is determined in most cases by its power.Smaller units have smaller motors and bigger sized disposals have big motors. There are a few exceptions, but if you want a powerful garbage disposal, you might have to enlarge the space under your kitchen sink.


Septic Tank Safe

It is vital to make sure your chosen garbage disposal is suited to your septic tank. If your septic tank is not big enough to handle a garbage disposal, you will ruin your sewage system. A smelly and costly problem.


Warranty & Support

WasteKing offers the longest warranties on all their units. Should a disposal system stop working because of a defect or mechanical fault during the purchaser’s lifetime, WasteKing will repair or replace the unit free of charge. Models to look out for with this warranty include the Waste King 9950 Legend Series 3/4 HP Continuous Feed Operation Garbage Disposer and Waste King 9940 Legend Series 3/4 HP Continuous Feed Operation Garbage Disposer.

InSinkErator also offers good warranties. Their Evolution series have a comprehensive 7-year, parts and labour guarantee. Other models such as the InSinkErator Badger 5XP 3/4 HP Household Garbage Disposer have a ‘’we come to you’’ 3-year In-Home Limited Warranty. The InSinkErator Badger 5, 1/2 HP Food Waste Disposer has a similar 2-year warranty. Both includes free house calls, parts and labour. It is worth checking the exact details of a warranty and making sure the support and after sales service is good.
