Septic tank is the obligatory sanitation system that should be used by us to keep our environment clean. Every toilet should be equipped with the septic tank that can manage the waste properly. As has been known by common people, the function of septic tank is to accommodate and manage human waste like faeces and urine or other waste that come from the toilet. Inside the conventional septic tank, it happens biological and chemical process by trillions of bacteria that have each other’s duty.
Generally, there are two kinds of bacteria: anaerob, the bacteria that needs oxygen to live and anaerob, the one that doesn’t need bacteria. Septic tank uses anaerob bacteria to manage the waste, that is why the lid of the main hole of septic tank should be closed perfectly to block the oxygen. It is dangerous if the oxygen gets into the septic tank, because some of anaerob bacterium inside will not work properly. As the result, the septic tank will release smelly odour from unmanaged waste.
The bacteria inside the septic tank release enzyme that manages the waste. They work slowly but sure, for two months, the bacteria are only able to decompose 50% of waste that is streamed to the septic tank and 80% for five months. In other words, if we poop today, it is only 50% of our faeces that can be decomposed for next two months.
To keep the performance of the septic tank and avoid some problems that might happen (like excessive capacity and the release of smelly odour from septic tank), it is necessary to maintain it regularly. One of the maintenances that should be done regularly is pumping.
Commonly the owners of houses who use septic tank think that if there is no problem happen in their septic tank, they don’t need to execute pumping maintenance. Actually that argument is totally mistaken. The solid waste that is streamed to the septic tank will settle at the bottom of the tank which creates the sludge layer, and the lighter waste like fat and oil float at the top which creates scum layer. The bacteria inside the septic tank cannot fully manage all the waste which means it will decrease the capacity of the tank due to the time.
It is very important to pump the septic tank every three to five years to keep it working properly. The larger number of people that use your septic tank will increase the water flow that is streamed to the septic tank and the tank will be filled up faster, therefore, you need more frequent septic tank pumping.
The ways to find out your septic tank needs to be pumped is by three methods:
The liquid waste of the septic tank overflows to the main hole.
Take a look to the inside of the septic tank by opening its lid.
The closet clogs and difficult to stream the waste.
It easier to call septic tank maintenance service to pump your tank, and it costs about $300 to pump your tank. The cost can increase due to the location of the septic tank and the capacity of the tank.
Pumping septic tank is the maintenance way that should be done for conventional septic tank, because it doesn’t have good filtration system to manage the waste. The cost of pumping is quite expensive too, especially when you have hard-to-access and large septic tank.
Why use conventional septic tank that has many problems when you can use the better one? Yes, biotech septic tank is the alternative sanitation system to manage human waste much better with its bio-filtration system.
