The system selected for the evaluation was a 900-gallon septic tank with 429 square
feet of leach field.
The system had completely malfunctioned. There was no drain evacuation and water
had penetrated through the soil above the drain field and was standing there. The
accumulation of bio-mass in the bottom of the leach field had created a shield (much
like a layer of petroleum jelly over sand) that prevented the wastewater from leaching
into the ground as designed.
1. The tank, usually concrete, holds sewage and allows solids to settle and partially
decompose. This gives most of the solids time to sink where anaerobic bacteria digest
the organic matter for several weeks.
The tank holds three layers of waste material: a scum layer of grease, fat, soap
and oil that forms along the top, an effluent layer of bacteria-laden liquid that
collects in the middle and a layer of solids that settle on the bottom.
2. A porous leach field allows effluent containing small solids to seep into the
soil, which further decomposes harmful pathogens and poisons before it reaches the
groundwater that feeds lakes, rivers and drinking wells.
The field has two parts: the pipes or tile and crushed rock that carry and disperse
the wastewater and the anaerobic bacteria that form beneath them. This breaks down
the residual organic solids that escape the tank.
Septic systems rely on the basic organic chemistry of bacteria decomposing organic
material. If you introduce chemicals that discourage the natural decomposition process,
organic solids will accumulate in the tank, displace liquids and overpower the leach
field. Common culprits include large amounts of chlorine bleach, harsh cleansers
and anti-bacterial products.
Because inorganic solids don’t decompose and some organic solids don’t break down
fast enough, they accumulate in the tank.
Septic systems are typically unable to degrade the bio-solids that accumulate in
the tank and leach fields. While indigenous microorganisms are present in most septic
systems, they are not capable of degrading the waste at a sufficient rate to keep
the system in proper operating order.
Estimated Cost of Repairs:
The repair/replacement cost the company had given the owner was broken down as follows
in 2004 prices:
$1500 Excavation and disposal of old system
$2300 New system and installation
$750 Replacement of irrigation lines
$700 Sod Replacement
Along with the expense, there would also be a period of six days that the owner’s
property would be in a state of total disruption.
The BioLife Septic Solution
First, the septic tank was pumped out. Water began to backflow into the tank from
the leach field. This was another indication that the leach fields were definitely
not working. The decision was made to pump the system because there was total blockage
in all drains and lines, and there was no other method to get adequate flow in system
to carry the product throughout the system.
BioLife Septicwas added at an application rate of 1 gallon per 100 gallons of
tank capacity directly into the septic tank. (9 gallons for the 900 gallon tank).
At the junction box, 1 gallon of BioLife Septic was added for each 100 square feet
of leach field in the system. (4.3 gallons for the 429 square feet in the leach
field). Note: If the leach system is a chamber type system, the product must be
added into each chamber based on the square footage of each line.
Within three days after treatment, the drains from the building began to flow more
freely. Ten days after treatment, drain evacuation was performing as good as new.
Sixty days later the bio mass accumulated in the bottom of the leach fields was
cleared and the wastewater began leaching as designed.
With slightly over 13 gallons of BioLife Septicthe malfunctioning system was restored
to normal operation. The owner saved $6,350 (2004 prices) in repair and/or replacement
expenses. This was and was done without the unpleasantness of having his property
in complete disruption of nearly a week.
Pumping a septic system too often can also cause damage. It takes six to eight weeks
to restore the natural anaerobic bacterial process after pumping, but the tank can
refill with liquid in as little as two weeks. This means the effluent that drains
into the leach field will contain more solids for weeks, which can stress or even
clog the field. BioLife Septiccan mitigate much of this problem if used properly.
