One of the major advantages of a Septic Tank System is that it has no moving
parts and therefore requires very little maintenance.
A well designed and maintained concrete or plastic aerobic septic system tank
should last fifty years. Due to corrosion problems, steel alternative
septic systems can be expected to last no more than ten years. One cause
of septic tank system problems involves a failure to pump out the sludge solids
and scum when required. As the sludge depth increases, the effective
liquid volume and detention time decrease. As this occurs, you may
experience septic tank toilet smells as sludge scouring increases.
Treatment efficiency falls off and more solids will escape through the outlet.
Scum may also begin to flow into the disposal system. The most common
cause of disposal area failure in your septic tank system is the accumulation of
scum or sludge which escapes from your septic tank and causes septic tank toilet
smells. This may then require the use of a concentrated septic tank
chemical. The only way to prevent this is by periodic inspection and
pumping of the tank.
After pumping, your septic tank system should be treated with a good septic
tank chemical on a monthly schedule, such as Super Dijest-It™ Concentrate Septic System
Digester which will help in reducing septic tank smell and sludge build-up.
Tanks should be inspected at intervals of no more than every year to determine
the rates of scum and sludge accumulation.
Please Note: The Super Dijest-It™ mentioned above can also be
effectively used in your RV Septic System. If inspection programs are not
carried out, a pump out frequency of once every 3-5 years is reasonable.
Once the characteristic sludge accumulation is known, inspection frequency can
be adjusted accordingly. The inlet and outlet structures and key joints
should be inspected for damage after each tank pump-out.
Actual inspection of sludge and scum accumulations in your septic tank system
is the only way to determine definitely when septic tank needs to be pumped.
When a tank is inspected, the depth of sludge and scum should be measure in the
vicinity of the outlet baffle of both chambers.
