    Question Can you use a garbage disposal on a septic system?

    We have moved to a house with a septic system. It's the first time for both the wife and I as were both raised as city kids with homes on sewer systems. The wife wants to install a garbage disposal in the kitchen. We've talked to some of the neighbors and the feedback is split almost right down the middle, so I thought I 'd see what the experts on here had to say. Feedback welcome please. Thanks!!

    Believe it or not I have seen ( one of my old houses) where the laundry and kitchen sink went to a separate " system" as it is considered " grey water and not black......was pretty shocked when I learned about this

    For what it's worth, I have been to 2 different meetings where we had guest speakers talk about such a topic, 2 things that we were told never to put in septic tank were grease and any type of food solids that were run through a garbage disposal, both speakers said that those two items will kill the bacteria and clog up drain lines faster than anything. One speaker even went as far a telling us to make sure we wiped out any fry pans to get the grease out with paper towels and to use baby wipes if you have sun tan lotion on to get it off. Supposedly the solids even though they are chopped up fine do not break down in the same manner as body waste does, we had our system on a 5 year clean out schedule, after the last cleaning the "Sheet Sucker" guy told us that we could go 7 -8 years as it was very clean.

    Every house I've owned has had a garbage disposal, but I've never used it. A good friend of mine is a very successful plumber in my area, has a big business. He says to never use a disposal, whether you are on septic or a sewer line. He claims its not worth the risk of having to pay for a clogged line at some point in time. I really see no need to use one anyway. Just throw the stuff you would grind up, in the trash.

    Of course I talk to myself...sometimes I need expert advice.

    Wow, not one but two meetings on the subject? Those must've been some rocking times!

    I've asked several people in the biz whether it's OK to use a disposal and near as I can figure, it's like cancer. There's things that you can do in life that increase your risk of getting cancer (e.g. smoking, sun tanning) but they don't guarantee that you will. If you use a disposal and your leach field fails, it's due to the disposal. If it doesn't fail, then it just doesn't--I guess that makes you lucky. We went more than 10 years between pumpings (with a disposal) and had no problems--there was still enough room for a couple more years. But I don't grind much stuff. My wife would prefer to use it for anything she can shove down the opening. I can see her point though. I compost all the veggie matter and sort other trash for recycling so we only generate 1 bag of trash per week. Food scraps can get pretty ripe after 5-6 days.

    Yup, used to be very common around here and I can show you one still set-up that way today. Grease, clothing fibers and soap (esp. bleach) are all considered enemies of the system so they'd dump it into a dry well.

    We have a disposal but only put minimal stuff in it.

    We compost all old food (except fats/oils) coffee grounds, banana peels, ect. put it our compost pile and make our own black gold.

    It definitely kills a lot of the good bacteria that helps a septic system function properly. If it were mine I would not be using a garbage disposal on a septic system.

    Been using one on my septic for 15 years and no problems ever. Other than grease and bones everything goes down it and use no additives either.

    It is like having ten people living in a house.The way I have seen people wast food it wood be like having 20 people on one tank. It is recommended to pump the tank five years with four people on one tank. And no disposal

    We do the same thing. All kitchen peelings, apple cores, banana peels, left over food, garden stuff, grass clippings, leaves, etc, all go into a compost bin. Also recycle everything possible and only take out 1 bag of trash per week.

    Think about this....most places that u have to have a septic system are in rural areas.....so I use a *green * garbage disposal......others call it a doberman. Serves 2 purposes, eats all leftovers and takes the lace of an alarm system!!
