Lack of or inadequate maintenance practices are some of the top reasons septic tanks fail. Here are some of the necessary septic tank maintenance practices and how your septic system may fail if you ignore these maintenance practices.
Pump the Tank Regularly
The septic tank separates liquid from solid waste; the liquid waste is rendered harmless and then disposed of into the septic field, while the solid waste settles to the bottom of the tank. Since solid wastes form only a small fraction of the wastes, it takes a long time for the sludge at the bottom of the tank to accumulate to serious levels. If that happens, the tank needs to be pumped; otherwise, it won't be able to handle any more waste.
Don't Use Harsh Chemicals on the System
The septic tank relies on microorganisms, actual living things, to break down the septic waste into harmless substances. Using harsh chemicals on your septic system, for example, when cleaning your drains, can easily kill these microorganisms and render the tank useless as far as waste treatment is concerned.
Avoid Non-biodegradable Materials on the System
As mentioned above, septic systems do their work due to the microorganisms that break down the wastes produced in the house. However, these microorganisms do not work on all wastes; they can't process plastic, grease or oil, metal pieces, and pharmaceutical products, among others. Therefore, ensure such non-biodegradable products don't go down the drains in your house.
Don't Use Too Much Water
Your septic system is only effective if the drain field can absorb the water it has treated. Too much water will over saturate the drain field and make it unable to absorb any more water. In such a case, your septic tank will have nowhere to take its wastes, and it will overflow.
Prevent Tree Root Damage
Small tree roots sometimes find their ways into septic pipes or systems via small cracks or disengaged joints. Once they are in the pipes, they grow fast due to the abundance of water and nutrients in the wastes. The pipes then end up cracking and spilling their wastes before the wastes can reach the septic tank. Therefore, don't plant trees near the septic system infrastructure, especially tree with deep or spreading roots.
Hopefully, you will maintain your septic system and it won't degrade and fail prematurely. Consult a septic company if you suspect problems with your septic system, for example, if all the drains in your house are slow.
