Wastewater Collection

The septic tank is connected to the plumbing system of your home, this is where the system collects all types of wastewater generated inside the household. Wastewater could be any water from sinks, showers, toilets, washing machines, and dishwashers.

Primary Treatment

After wastewater leaves your home and enters the tanks, primary treatment begins. Solid particles in the water such as food scraps and human waste, settle at the bottom of the tank, forming a layer of sludge. Whereas lighter particles like fats and oils form a scum layer at the top.

Biological Breakdown

A natural biological process occurs to further treat your wastewater. Bacteria will break down and decompose organic matter in the sludge and scum layers to reduce the volume of solids. This helps in the natural treatment of wastewater. If this process slows down or has trouble occurring is when you want to call for septic tank services to speak to an expert.

Effluent Discharge

The effluent — which is partially treated water — exits the septic tank through an outlet pipe and flows into the drain field. This part of the sewage removal process allows for the effluent to percolate into the soil gradually making room for more wastewater in the septic tank. Regular septic tank maintenance in Marietta, including seasonal pumping, to remove sludge and scum is essential to ensure your system is functioning efficiently.
