Questions we get asked, frequently.

Why would I ever need an alternative septic system?


Typically local regulations and soil conditions of your unique home site may dictate the need for a treatment (sometimes called “pretreatment”) system. Your Fuji Clean treatment system accepts wastewater from your home, cleans it and sends clean water back to the environment (usually into a soil absorption system such as a leach field).


The advantage of this process is that our systems do the purification work ordinarily accomplished by the soil, and therefore this allows smaller, shallower and less obtrusive drain fields. Additionally, pretreatment greatly extends the life of a drain field since clean water deters solids and biological buildup (biomat) in your soil absorption system. Also, in some regions, treatment is required to reduce nutrients such as nitrogen or phosphorus from your waste stream as protection against contamination of water bodies.


Our system is installed on our vacation home. Should I turn it off when we are not home?


Fuji Clean systems are designed to accommodate variable and intermittent flows, including only weekend use, although the air blower operates continuously regardless of inflow. However, for seasonal use properties, the air blower may be shut down if the system is not going to be used for an extended period of time. The blower should be re-started at least three days in advance of system use if possible. 


What if there is a power outage? 


During a power outage, the blower will cease operation and after about twenty-four hours treatment quality will diminish. However, the most alternative wastewater treatment systems will still allow wastewater to pass through and will not create a backup in the house unless a separate pump station has been installed.


Does my system need servicing?


 Alternative Systems like Fuji Clean system, Fusion, Advantex are designed to require minimal service, although a schedule of regular inspection and service is necessary. Inspection and service every six months is necessary during the first two years of use to assure proper operation. States vary in terms of service requirements after the initial two year warranty expires, but for example, Fuji Clean's extended service policy mandates semi-annual inspection or service visits from a trained and certified provider. (This schedule may be altered for seasonal and part-time use). Your certified service provider will review details of our initial (first two years) and extended (two years +) service plans.


Does my system need to be pumped out? 


Like an ordinary septic tank, sludge must be removed from your system periodically (such as once every two - four years). Your service provider should provide guidance for you on this and if necessary will help to arrange for a septic tank pumping company to provide this service. Pump-out frequency depends on waste stream strength and use; please consult with your service provider to help determine the frequency that is best for you. Also, please note: use of a garbage disposal may increase pump-out frequency.


How much will it cost in electricity to run my system?


Since your Fuji Clean system has been designed to operate continuously, it is easy to calculate power cost. All residential units draw 1.3 kWh of power per day except the CEN10, which draws 1.9 kWh of power per day. Simply multiply your local cost of power by the draw per day to calculate daily power cost.


Can I use a garbage disposal with my system?


Fuji Clean treatment systems will accommodate waste flow from garbage disposals. Due to the increased organic load you may have to pump the sludge from your system on a more frequent basis; your service provider should be aware that a garbage disposal is in use and will help you determine the proper pump-out frequency.


How will laundry bleach affect my Fuji Clean? 


Your Fuji Clean system is dependent on live bacterial microorganisms to clean wastewater. Therefore, it is in your best interest to avoid the heavy use of bleach as much as possible. If you must use bleach, use it sparingly and spread out its use over time.

One recommended detergent is Ecos laundry detergent.  Visit:  


Is there anything that I should definitely not put into the system?


Since your treatment system is a living culture, you should avoid flushing or draining toxic materials into the system such as paint, household chemicals and antibiotic medicines as they can harm the natural bacterial action that is present. Other items to avoid flushing into the system include bulky or non-biodegradable materials in general such as sanitary napkins, paper towels and cigarette butts. Coffee grounds and excessive cooking grease are not helpful to efficient system processing and should be disposed of through your compost/recycle/solid waste stream instead of though your treatment system.


What if I need to disinfect a well?


On occasion, a contaminated well needs to be disinfected (usually with Clorox bleach). If you need to do this, do not run the chlorinated water through your septic system. Instead, open the outside water faucets and let the water run for several hours or as long as necessary to flush the chlorine out of the well. Meanwhile, avoid using water inside the house.


Will toilet additives help my system?


Unfortunately, no. Toilet tablets and drain-clean products will generally deplete necessary bacteria from the system. Products that advertise drain field health are typically unhelpful to the system and often temporarily emulsify fats, oils and greases, only to re-coagulate after they reach the drain field.


Is there anything I should do inside the house to help the system?


Absolutely. Be sure that plumbing fixtures such as toilet bowl fill valves and faucets are maintained and do not leak. You would be amazed at how much water passes through the system with a small leak or dripping faucet. Your system is sized to meet standard flows from your house and therefore any excess flows will not help water treatment. Remember that maintenance of these fixtures also conserves your water.


What if I hear the alarm?


Your alarm/control panel monitors all important functions of your Fuji Clean system and an alarm (both audio and visual) will be triggered in the rare event of a problem, such as water is not being discharged from the system or your air blower is not operating properly. In the event of an alarm condition, go to the alarm panel, find the toggle switch on the outside right and push toward “silence.” This will mute the audio alarm, although the visual alarm light will remain lit. Next, contact your service representative for assistance. The contact information for your service representative should be affixed to your alarm panel.


How does Fuji Clean accomodate low flow systems?


Studies of the Fuji Clean system with flows as low as 10% capacity showed little change in treatment performance. Even after 6 months of no flow, research indicated that microbes survived in a dormant state and treatment rebounded immediately when flow was reintroduced.
