According to many septic tank owners, they do not deem it necessary to clean it unless the system has issues. The problem with this logic is that the owner ends up paying heftily for not maintaining their system. Regular pumping of the system removes the solid materials that begin to form at the bottom of the tank.
If the solid layer forming at the bottom is left unattended, the tank starts to have issues that will cost more to fix. Cleaning your septic tank prevents the solid from clogging soil pores when it escapes into the drain field.
Since septic tanks do not self-clean, it is up to the owner to schedule when the pumping occurs. Most tanks have the capacity to last at least three years after which they need cleaning. How often to clean your tank depends on the number of people using it and the size of the reservoir.
In a family of more than four people, the amount of waste is high, and therefore a yearly pump is the best option. Families of one and two people can pump their tanks after three or five years. There are many factors to consider, however, the number of individuals is not the only determinant.
A 3000 liters tank can last at least three to five years. If the level of solid accumulating at the bottom exceeds this period, then you run the risk of clogging the soil absorption system, and the waste will start coming up to the surface. When this happens, be ready to spend money on emptying the tank and repairing the soil absorption system.
Ensure to pump your septic tank at least once every three years if you do not have a garbage disposal. If you have a garbage disposal then once every year is the best frequency to clean out the tank. Have a licensed contractor take care emptying your tank and collect all the necessary receipts. The local board of health should get copies of the receipts to track and ensure the safe disposal of the waste.
