Are 'Flushable Wipes' safe for my septic system?

Are 'Flushable Wipes' safe for my septic system? 

The answer - NO! 

Although manufacturers market some wipes at 'flushable', these wipes may not break down quickly enough (if at all) in your septic tank, like toilet paper does. An overload of wipes may cause a blockage in the septic system and may result in a backup of your septic system, costing you hundreds to thousands of dollars in repairs.

The best advice for disposing of anything other than toilet paper - put it in the trash!

Filter Friday - Effluent Filter Maintenance

Do you have a filter in your septic system? If you have a newer system, you will have a filter on the outlet baffle of your septic tank. 

What does a filter do for my septic system? Filters prevent solids from leaving the septic tank and entering your septic bed. If solids enter your septic bed from the tank, there is the potential for them to accumulate and cause a failure of the bed (and contents from the tank may eventually back up into the house). 

What maintenance is required for my filter? It is important that the filter is cleaned annually to remove any build up of solids that is preventing liquids from entering the septic bed. 

Cleaning a filter is simple - just rinse it out with a garden house!

This picture shows a clogged effluent filter that requires cleaning. If the liquids cannot enter the septic bed, a back up of the contents of the septic tank into the house may occur.

YOU ASKED - The 'when' and 'what' of septic system pumping

How often do I need to pump my septic system?
When to pump a septic system depends on the age and capacity of the tank and the usage of the system (number of users, frequency of use). 
  • It is recommended that a system is pumped out every 3 - 5 years.
  • Under the Ontario Building Code:
    •  "a septic tank must be cleaned whenever sludge and scum occupy 1/3 of the working capacity of the tank" (Section
  • Pumping your system on a regular basis allows you (or your pumper) to ensure all components of your septic system are properly working.

What you need to know when a pumper comes to clean your tank
  • Septic tanks with two compartments (most tanks installed after 1973 will have two compartments) will require both to be accessible so they can be pumped out.
  • A pumper may "backwash" the tank  to remove any accumulation of solids at the bottom of the tank which can then be easily removed. 
  • On average, pumping of a septic tank should take between 20 to 30 minutes to complete.
  • After a septic system is properly pumped, there should be very little scum, sludge or liquid remaining in the tank.
  • If your system has an effluent filter, it is good practice to have your filter cleaned annually as well as at the time of pumping.

Septic Care: A New Wastewater Treatment Challenge

Microfibers released in washing machines can wreak havoc on soil treatment systems over time

Link to Full Article

New studies indicate that the fibers in our clothes could be poisoning our waterways and food chain on a massive scale. Microfibers — tiny threads shed from fabric — have been found in abundance on shorelines where wastewater is released. In fact, 85 percent of the human-made material found on the shoreline were microfibers, and matched the types of material, such as nylon and acrylic, used in clothing. Microfibers are so small, too small to see. They can be as small as 3 microns. In comparison, a human hair is 50-100 microns.
In a recent study, researchers at the University of California at Santa Barbara found that on average, synthetic fleece jackets release 1.7 grams of microfibers each wash. That’s approximately 1,900 individual fibers. For those connected to a sewer system, the microfibers travel to the local wastewater treatment plant, where up to 40 percent of them enter rivers, lakes and oceans, according to the research findings. Synthetic microfibers are particularly dangerous because they have the potential to poison the food chain. The fibers’ size also allows them to be readily consumed by fish and other wildlife. These plastic fibers have the potential to bioaccumulate, concentrating the toxins in the bodies of larger animals higher up the food chain.
These tiny particles also have the potential to impact septic systems, since most washing machines don’t filter out particles and the current available add-on filters designed to keep lint out of septic tanks still don’t catch the tiniest fibers. Since the particles are so small they will be resistant to settling in the septic tank and will pass through effluent screens. It is likely that most of these fibers are captured in the soil treatment system, creating concern for plugging of soil pores over time.
There appear to be no easy answers. One way to begin to address the problem is to try to make clothes that shed fewer plastic fibers when washed. Researchers are working collaboratively with designers to create fabrics that are more durable and release less plastic waste during wash cycles.
Another way to address the problem is to tell customers to reduce the amount of times synthetic clothing gets washed, and when need be, use washing machines with filters installed that catch the microfibers in the wastewater. Although filters are not a common feature in washing machines, some manufacturers do include them and aftermarket filters are commercially available (although they currently do not filter out microfibers). Other, more innovative filters are under development. One example is the Rozalia Project’s microfiber catcher, which will collect microfibers as well as hair, and prevent them from flowing out with the drain water, and is reported to be available in 2017. It is also better to use front-loading, high-efficiency washing machines instead of top-loading washing machines. Researchers found that top-loading washing machines released five times more microfibers than front-loading washing machines, and the more you wash it, the worse it gets (aged jackets released almost two times the amount of new jackets).
The final place to catch microfibers before they are flushed to surface waters is at wastewater treatment plants. Although a typical secondary treatment plant will NOT do an effective job removing microfibers, plants that employ tertiary treatment to produce reclaimed water for non-potable uses typically use filtration that would remove microfibers. Wastewater treatment plants that use advanced treatment to produce potable water use microfiltration (as well as other technologies), which will also effectively remove microfibers.

What you need to know: Owning an Advanced Sewage Treatment Unit

What is an Advanced Sewage Treatment Units: a form of sewage treatment that provides secondary or tertiary effluent (sanitary sewage) treatment before it is directed to the leaching bed.

What is the Property Owner’s responsibility for the maintenance of a treatment unit?
1.   Inspection Documentation and Maintenance Contract
                       i.       Obtain a copy of the annual maintenance inspection report completed by a manufacturer trained provider and proof of service manufacturer training
                      ii.       If a maintenance contract is no longer valid, it is the responsibility of the property owner to renew/renegotiate a contract. A property owner without a current contract or proof of regular servicing is in violation under the Ontario Building Code (, as it states:

“No person shall operate a treatment unit other than a septic system, unless the person has entered into an agreement whereby servicing and maintenance of the treatment unit and its related components will be carried out by a person who:

(b) Is authorized by the manufacturer to service and maintain that type of treatment unit”

2.   If the property ownership changes, the current owner is obligated to disclose existing contracts and advise the service provider of the new owner’s contact information.

What is the Service Provider’s responsibility for the maintenance of a treatment unit?
1.   Conduct maintenance inspections on the treatment unit in accordance with the guidelines suggested by the manufacturer. Sampling of treatment units as per Section (2) of the Building Code must be completed:
                       i.       Once during the first 12 months after the sewage system was put into use
                      ii.       Thereafter, once during every 12 month period, at least 10 months and not more than 18 months after the previous sampling has been completed.
2.   To provide sufficient notice to property owner that contract is approaching expiry and make necessary arrangements for renewal in a timely fashion.
3.   Reflect any changes on the contract which may affect adequate servicing as per contract.
4.   Indicate on the contract if property owner account is in good standing or suspended during life cycle of the agreement.

What if my service agreement was not renewed and is expired?
Without a current contract or proof of regular servicing, the property owner would be in violation of the Ontario Building Code (, which stipulates that:
“No person shall operate a treatment unit other than a septic system, unless the person has entered into an agreement whereby servicing and maintenance of the treatment unit and its related components will be carried out by a person who:

(b) Is authorized by the manufacturer to service and maintain that type of treatment unit.” 

Failure to have a valid & current contract will result in an Order to Comply issued by the Township C.B.O. If the property owner takes no action, this will result in a summons to court under section 36 of the Building Code Act, 1992.


Ontario Building Code

Ontario Building Code (
Every manufacturer or distributor of a treatment unit shall provide, for each model sold, printed literature that describes the unit in detail and provides complete instructions regarding the operation, servicing, and maintenance requirements of the unit and its related components necessary to ensure the continued proper operation in accordance with the original design and specifications.

Ontario Building Code ( (2))
No person shall operate a treatment unit other than a septic tank unless the person has entered into an agreement whereby servicing and maintenance of the treatment unit and its related components will be carried out by a person who (b) is authorized by the manufacturer to service and maintain that type of treatment unit.

Ontario Building Code ( (3))
The person authorized by the manufacturer to service and maintain the treatment unit and who has entered into the agreement referred to in sentence (2) with the person operating the treatment unit (Property Owner) shall notify the chief building official if,
(a) the agreement is terminated, or
(b) access for service and maintenance of the treatment unit is denied by the person operating  (Property Owner) the treatment unit.

If the above regulations are not adhered to, the Advanced Sewage Treatment Unit no longer conforms to requirements of the Ontario Building Code.
