This chapter discusses How to diagnose a clogging failure of the septic drainfield as one of the types of septic system failure in the drain field, leach field, seepage bed, or similar
component. We list the causes of each type of septic component failure, and list the septic component failure criteria
or in other words what conditions are defined as "failure"? How can you distinguish between a blocked pipe, a septic tank that
needs pumping, and a clogged drainfield that needs replacement?
This is an important question as it distinguishes between relatively
low cost maintenance or repair task and a costly septic leach field replacement.
We also discuss what can be planted over and near a septic drainfield and what should be avoided.
Also see Drainfield Location: how to find the septic drain field or leaching bed.
DISPOSAL CLOGGING FAILURES - Effluent Disposal and Drain Clogging Failures
In simplest terms, there are two visible septic effluent or onsite wastewater disposal failures:
Toilets or other fixtures back up into the house - but

Effluent or sewage appears at the surface of the yard, or the neighbor's yard!
Septic odors may also indicate a system failure or an imminent failure. But such odors
may also be produced by defects in the plumbing vent system or other site conditions.
Beware, sewer gas contains
methane and is explosive if it reaches a dangerous concentration inside a building.
Typical causes range from things that are easy and cheap to repair, to a need for complete system replacement:
