A very typical and common problem:
Septic systems are typically unable to degrade the bio-solids that accumulate in the tank and soakaways. While indigenous microorganisms are present in most septic systems, they are not capable of degrading the waste at a sufficient rate able to keep the system in proper operating order. In the best case, the tank must be pumped out by a ” Honeysucker” or similair sludge removal equipment. In the worst case, the system fails to a point where it must be removed and replaced at a cost of thousands of Rands, and certainly much greater for larger commercial systems.
A typical problem will be a sewage/ septic tank system that has completely malfunctioned and where, with no effective drainage, the water pushes through the soil above the soakaway, creating standing pools of untreated and smelly waste water. The accumulation of bio-mass in the bottom of the soakaway will have created a shield (much like a layer of petroleum jelly over sand) that prevents the wastewater from leaching into the ground as designed.
Normally to repair or replace a simple system the client will need to:
- Excavate and dispose of the old system
- Install a bioreactor, clarifier and disinfection system
- Replace the old irrigation lines
- Replace the soil
- Provide new landscaping
Along with the expense, there would also be a period of time that the owner’s property would be in a state of total disruption.
The Biozone Remedial Solution:
The first process will be to empty the septic tank to allow the water to begin to backflow into the tank from the soakaway. This will confirm that the soakaway is definitely not working. If there is a total blockage of all drains and lines, there will be no other method to get adequate flow into the system to carry the Biozone product throughout.
Then add Biozone Bioremedial solution at an application rate of 5 litres per 400 litres of tank capacity directly into the septic tank. At the distribution (junction) box, 5 litres of Biozone Bioremedy needs to be added for each 10 square metres of soakaway in to the system.
(If the leach system is a chamber type system, the product must be added into each chamber based on the square metres of each line).
Within three days after treatment, the drains from the building should begin to flow more freely. Ten days after treatment, drain evacuation should be as good as new. Sixty days later the bio-mass accumulated in the bottom of the soakaways should be cleared and the wastewater begin leaching as designed.
As an example with 50 litres of the Biozone Remedy on a 3500 litre system with 40 square metres of soakaway, the malfunctioning system should be restored to normal operation. There will be a massive saving in repair/replacement expenses, and the owner will not be exposed to the unpleasant event of having the property in complete disruption during the repairs and re-growth of the lawn or garden.
The recommended maintenance dosage of a system experiencing problems is 5 litres per month for a six month period. The maintenance dosage thereafter, and for general maintenance of an operational system, is ½ a litre per month.
