Septic tanks are frequently used in
areas where sewer systems are not present for treatment of individual
residents wastewater. The overall septic system typically includes an
actual tank where solids settle, as well as a drainfield, through waste
water percolates into the ground. Improperly functioning septic tanks can
cause health problems, usually as a result of contact with sewage.
Sewage system maintenance is typically overlooked,
although most septic systems, to function properly, must have their solids
pumped out every several years. If this is not done, solids enter the
drainfield system, eventually clogging it.
Where septic systems are present at a property,
appropriate inquiry should always be made prior to completion of the
property transaction. If the location of the septic system is not known,
then it is likely that solids have not been cleaned out on a regular
basis. A qualified system inspector should be engaged to determine whether
the size of the septic system is adequate for the residential or the
commercial facility, and the system should be inspected.
In extreme situations, occupancy of the residence
can be disallowed if there is a non-functioning or inadequately
functioning septic system. At some locations with shallow groundwater
levels, where traditional septic systems which cannot meet sanitary codes,
more expensive "sand mound" systems are needed, such that the
wastewater percolates in an aboveground mound.
Inspection of septic systems by qualified
professionals is highly recommended where ever a septic system is used for
wastewater service at a property which is going to be subject to sale.
