Is Biological Laundry Powder Septic System Safe?

Can anyone tell me if I am correct in thinking that you are not supposed to use biological washing powder if you have a septic tank? Does its use upset the system?


Many thanks.

Biological detergent

A biological detergent is a laundry detergent that contains enzymes. The description is commonly used in the United Kingdom, where other washing detergents are described as "non-biological". The terms are sometimes abbreviated to bio and "non-bio".

The purposes of the enzymes is to break down protein, starches and fat that may be found in dirt and stains upon clothing to be laundered, for example food stains, sweat or mud.

Some people may be allergic to the enzymes. The selling point of non-biological detergents is that they are gentler, causing less irritation to skin ("kinder on the skin") and less damage to the fabric. Some studies refute the claim that non-biological detergents are gentler.


We were on a septic system for years and never really had any problems with laundry detergent clogging it up.

I would advise using a liquid laundry detergent instead of a powder.

Here's a website, see if you can buy this septic system treatment in England.

The bio detergent is just food for the septic tank bacteria. They love it. It's the non-bio detergents and solvents that you should avoid. If you accidentally murder your septic tank, you can usually quite easily re-start it by diluting the solvents with a few bath tubs worth of water and then flushing some organic non-pasteurized yoghurt and some moldy bread,
similar to re-starting the beneficial bacteria in your intestines after anti-biotics or chemo-therapy.

Have fun! DearWebby

I believe its safer for the septic system than regular detergent. REgular detergent interferes with the ecosystem in the tank and kills off the natural bacteria. Try to stay away from harsh cleaners that do that.
