It is suspected that many of the conventional septic systems in British Columbia look similar to this failed gravity distribution pipe. This type of build up occurs over time and is usually due to an undersized septic tank or absence of an effluent filter. Solids that have not had an opportunity to settle out of the effluent in the tank carry over into the distribution pipes. A filter on the septic tank could have prevented this problem. A yearly maintenance inspection is recommended to avoid such problems. If your septic system is 10 years old or older you may not have a filter. This is recommended and can be retro fit with relative easy by a maintenance provider. The typical life span of a septic system is 25 years. There are many systems that are still operating safely. These systems are always maintained and used with care through their life span by a conscious owner.
If an effluent filter is to be added to your existing system, be sure to check the daily design flowrates of effluent from your residence and compare it to the capacity of the effluent filter.
Maintenance Regularity
In the first year after installation, maintenance visits must be carried out every six months, and once per year after that. Pump out of the septic tank should occur every 3-4 years. Visual inspections on a yearly basis will indicate when it is necessary to pump out your tank.
During a yearly inspection, the following items should be investigated as a minimum:
Functionally test all mechanical components
Clean Effluent filter on outlet of tank
Visually Inspect all tanks and components
Collect and submit an effluent sample to an accredited laboratory for BOD, and TSS analysis.
Check the inspection port at the end of the field for water level
Note type and amount of vegetation present over trenches
Add soil to settled or disturbed areas of the backfilled areas
