What is a Septic Tank?
The septic tank is composed of either a two or three chamber system. This system retains sewage from your property for a period of time so that the solids will form sludge at the bottom of your septic tank.The sludge will be naturally broken down and the effluent from the tank drains from the tank through an outlet pipe. Tanks are installed when there is no main drainage available and are always buried in the ground.
How does it work?
Sewage treatment systems are basically a means of slowing down the flow of sewage to provide ample time for the enzymes and bacteria to break up contamination naturally. It is the collection point for sewage and allows the sludge formed at the bottom to settle out of it.
Why do you need to empty a septic tank?
It’s highly unlikely that all of the sludge at the bottom of your septic tank will every disappear. It will always build up and over time will need to be taken out of the tank. Emptying your tank isn’t really emptying it totally as a contractor will only take the sludge and leave the watery effluent in. This effluent contains billions and billions of good microbes which is necessary for your tank to work properly.
My tank has a scum on top. Is this OK?
As long as it’s “liquidy”, it’s ok. This built up of scum contains fats, oils, and grease from cooking and washing. Over time enzymes will break them down but if it gets too thick, it can dry out and become solid. If the scum is hard and dry, it’s probably a sign that you should get in a contractor to pump your septic tank.
How often should I de-sludge my tank?
Follow your manufacturer’s recommendations with regards to how often you should de-sludge your tank. Using bioaugmentation products will also decrease the build up of sludge in your tank because it facilitates its break down.
What is Bioaugmentation?
The addition of bacteria. This augments the existing biological population, or biomass which facilitates the break down of solids.
Why do we need to add bacteria?
Like all living things, bacteria dies. Adding bacteria guarantees that your septic tank has the right amount and right kind of bacteria in it to ensure proper break down of sludge.
Is there anything I shouldn’t flush down the loo or pour down the sink?
Bleach or any “biocide”. Paints, solvents or caustics. Keep the amount of kitchen bi-products such as oils, fats, and solids from going into your system. Your system cannot readily break down physical blockages such as cigarette butts, napkins, and the ever so popular – ball of hair. These types of blockages will require physical removal of the blockage.
Can I just put a dead rabbit in my septic tank to get it started?
A classic example of using the wrong bacteria in your septic tank. The right type of bacteria needed in your tank is found in the soil and not in any animal’s insides.
My tank stinks! What’s wrong?
Probably the number of bacteria has lowered significantly to the recommended levels. It is in need of adding more bacteria into the tank and then try to see and find out what killed your septic tank’s bacteria. More than likely it is a cleaning product you use at home that has found itself in your septic system.
