How does temperature affect septic tank function?

Temperature plays a crucial role in the effectiveness of a septic tank system primarily because it influences microbial activity. Microorganisms, which are essential for the breakdown of waste in septic tanks, thrive within a specific temperature range. When temperatures are too high or too low, the metabolic processes of these bacteria can be significantly disrupted.

In extreme heat, bacteria that are integral to the anaerobic digestion of waste may become stressed or die off, leading to an increase in the accumulation of solids and untreated waste. Conversely, in very cold conditions, bacterial activity slows down, which can lead to insufficient breakdown of waste materials.

This means that maintaining an optimal temperature range is vital for ensuring that the septic system operates efficiently and effectively. Thus, the correct choice identifies that extreme temperatures can indeed disrupt microbial activity, which is essential for the proper function of a septic tank.
