Septic Safe Products and the Ones to Avoid

A septic safe wastewater treatment system is an environmentally friendly choice for homeowners and sometimes the only choice for a cottage or rural homes that are outside of the municipal sewage system. It also means that what you wash down the drain is even more important, and this includes your cleaners. Read on to learn about septic systems and how your cleaning products can affect them.

What does it mean to be “Septic Safe”?

If you’re raised in a city, chances are you have little knowledge of Septic Systems. To answer all the questions you’ve never had, Septic Systems are an alternative drainage system for rural homes without centralized sewage piping. They bring waste and water from a home into a specialty septic tank which uses bacteria to separate waste from water. These tanks use perforated pipes which then release the water into a patch of soil called a drainfield. The drainfield then naturally cleans the water using different layers of rock and allows it to return to the ground water systems.

Septic Systems are a closed loop system and contribute to the efforts of the Zero Waste Movement. Learn how you can shrink your own footprint and begin a Zero Waste journey.

Why people choose septic systems

The advantage of a septic tank is that they are far cheaper and durable than sewage pipes. Because it is a closed system that requires no external energy, it does not generate a monthly bill and can last for decades without needing replacement.

Environmentally, septic systems create a positive contribution to the health and wellness of the local ecosystem. When the water is being pushed through the drainfield it helps nourish local bacteria and microorganisms which in turn stimulates plant and bacteria growth. This nourishment leads to a supply of food for local birds, insects and larger animals.

Because of this, if products which contain toxins are introduced to these systems, it can have major repercussions not just for the mechanisms of the tank, but for the entire ecosystem. Septic systems are not designed to protect ground water from the chemicals found in certain household products and may pose a significant risk to human health and the environment. If these products are introduced to a septic system, it can kill the bacteria within the tank which will stop water separation, and worse, could poison the surrounding waterways.

There are many natural options for say, disinfectants, that exist which will not harm a septic system. For some of the stronger natural disinfectants such as Hydrogen Peroxide and Thyme Oil, their strength will still require them to be diluted with water before being introduced to the system.

Household products to avoid

Water Softeners

  • Water Softeners can harm the bacteria within the sepic tank and release greater concentrations of waste and grease into the drainfield

Oil, gasoline, paint thinners, solvents, photographic chemicals, weed or insect killers

  • These materials will poison Septic Systems and threaten the water supply

Cooking Grease

  • Thick cooking grease, like from bacon, can solidify in the tank and clog incoming and outgoing pipes

Bath Oils

  • While these oils feel great, they can clog the drainfield and coat the waste within the tank making it unable to break down

Kitty Litter

  • Most kitty litter is clay based and can clog pipes

Cleaning products to avoid

Anitbacterial cleaners and disinfectants

  • Anitbacterial and disinfecting products are necessary for most domestic situations (they were designed to sterilize hospitals) and will kill beneficial bacteria that help your septic tank function. 

Chlorine Bleach

  • Too much bleach can kill or disrupt the bacteria within a septic tank. It is also toxic to aquatic life. If your septic tank is located close to a natural water system,  there is a high chance that bleach from your wastewater is being directly released into the groundwater through your septic system. 

Chemical Drain Cleaners

  • Unclogging the drain with these materials will kill the bacteria in tank and necessitate costly repairs

Products containing methylisothiazolinone 

  • Methylisothiazolinone is a synthetic chemical used in consumer products for its antimicrobial properties. It is most often applied to cleaning products as a synthetic preservative. Not only is it a common allergen, but several studies have shown that it is also toxic to aquatic life.

Septic safe cleaning products

100% Natural

Biodegradable

  • You should only use products that are made with biodegradable ingredients that will break down in a natural environment, as opposed to persistent synthetic chemicals which can build up. 

Third-party Certified

  • To ensure that the products that pass through your septic system and into the environment won't have a negative impact, it is important to look for a verification from a third-party such as Ecocert or The Environmental Working Group. This way you can be sure that the products you choose are actually better for the environment and aren't simply making unsubstantiated "green" claims for branding.

Septic safe cleaning products list

Septic systems are delicate. Just two gallons of chlorine bleach can kill off the functioning bacteria in a 1,000-gallon septic tank. 

While a small amount of the wrong chemicals can wreak havoc on your system, most all-natural cleaners are septic safe. Use non-chlorine, non-ammonia, non-antibacterial, non-toxic, and biodegradable cleaning products to help keep your septic system in working order. 

The following natural, everyday products are safe to clean and disinfect your home with:

  • Distilled white vinegar
  • Lemon juice
  • Baking soda
  • Borax
  • Salt

Septic safe bathroom cleaners

It’s simple to use all-natural cleaning products in most areas of your home, but the one room in your home where chemical cleaners are often a given is the bathroom. Having a clean bathroom is important for your health, but disinfecting your shower, tub, and other surfaces doesn’t require harsh chemicals. 

Here are a few effective natural bathroom cleaners that are septic safe:

  • White Vinegar - The natural enzymes will break down soap scum and odors.
  • Baking soda - The rough texture is perfect for making bathroom fixtures shine.
  • Borax - mix ½ cup with water for superior disinfecting strength on surfaces.

Toilet cleaners safe for septic systems 

The toilet is a notoriously dirty place. It can be tempting to use heavy-duty cleaners to make sure germs are demolished. 

Many toilet bowl cleaners contain bleach and some are even made with hydrochloric acid. But natural, plant-based cleaners are tough enough to clean your toilet and are safest for your septic system’s health and the health of your family. 

Avoid using cleaners that contain toxic bleach, ammonia, phosphates, or petroleum-based chemicals, which can harm your septic. Instead, use proven natural cleaners. 

Here is a list of natural, septic-safe cleaners for your toilet:

  • Baking soda - An inexpensive and effective scouring agent. Pour half a small box of baking soda into the toilet bowl and let it sit overnight. In the morning, flush the mixture before scrubbing with a toilet brush.
  • White Vinegar - The acidity of household vinegar is helpful for breaking down hard water stains in the toilet bowl. Pour a cup of vinegar into the bowl and let sit overnight, then scrub in the morning. Just don’t use vinegar and baking soda together, as they’ll cancel each other out and become ineffective.
