Why the Water in the Septic Tank Has Turned Pitch Black?

Home

When the wastewater enters the septic tank, it is generally yellow in color. In some situations, the water in your septic tank can turn pitch black. This is not a natural incident and it happens for some very specific reason. When it happens, you need to understand that there is something wrong with the septic tank water. The water will turn pitch black if the septic tank is corroded. Or this can happen if there is contamination by inorganic waste.

Septic Tank Cleaning

When it turns black, you immediately need to address the issue by calling an agency for septic tank cleaning. They will come with the necessary equipment and will help you clean the water and scum, and find the real issue about the tank and why the water has turned black.

In the following points, you will get to see the reasons that might turn your septic tank water black. Take a look.

Corrosion of the Iron

In the septic tank, the sulfate-reducing bacteria anaerobic remain very active when the water source or the wastewater that gets in the tank has more sulfate in it. These bacteria produce the gas hydrogen sulfide that smells very much like a rotten egg. If your septic tank or any component of it is made of iron, then this gas will have a reaction with the metal and will create black iron precipitates. This is what makes the septic tank water completely black. The easiest remedy is that you steer clear of the iron septic tanks. As the reaction cannot be controlled, replacing the iron septic tank with plastic, concrete and polymer will help you deal with the issue. Also, frequent cleaning of the septic tank is necessary. If cleaned regularly, it will keep the septic tank cleaning prices low for you.

Increase in the Organic Load in Advanced Septic System

At times, the nature of receiving environment, soil condition and wastewater make it difficult for the conventional septic systems to work properly. In situations like this, advanced septic systems are installed. These are actually designed with the purpose of reducing biological oxygen demand, pathogen, total suspended waste and some nutrients in the wastewater. This type of system depends on the anaerobic bacteria for breaking down the organic solid.

The bacteria remain suspended in the wastewater inside the advanced septic system. But if there is something that is hampering the process of breaking down the organic waste, then the functionality of the septic tank will be compromised. The bacteria will not get the oxygen and as they cannot thrive without oxygen, the process of breaking the organic waste will stop. The increasing level of organic waste can turn the water in the septic tank black. If your tank has an issue like this, you need to get in touch with the supplier immediately. Also, search for agencies for septic tank emptying near me.

Contamination by Inorganic Waste

Keeping inorganic waste completely out of the septic tank system will not be possible. The bacteria work on the organic waste breaking it into liquid that is ready for the next stage of treatment. But the bacteria cannot work on the inorganic waste. This goes down and settles in the sludge layer. When the septic tank is cleaned, this is also cleaned. But if the inorganic waste settles inside the tank too much and the tank gets filled very quickly, then the septic tank water can turn black.

So, now, as you know about the reason why the septic tank water can turn black, look out for them. Also, keep the phone number of septic tank cleaning companies handy.
