Your Guide to Protecting Your Septic Tank During the Rainy Season

A septic tank takes care of the solid and liquid waste generated in your home. While this system is not difficult to understand, you must understand how a septic tank works, how weather can affect its performance, and what the best solutions are for protecting it.

A typical septic system is divided into two parts. The first is a septic tank, which collects wastewater from your home. Billions of beneficial living microorganisms in the tank decompose the organic waste. While heavier solids like fats, oils, and grease settle to the bottom, lighter solids like fats, oils, and grease rise to the top to form a scum layer. The treated liquid, known as effluent, is released into the drain field, the second part of the septic system. The liquid effluent percolates through the gravel and is absorbed by the ground.

How Rainy Season Affects Your Septic Tank

Although the rain provides much-needed relief from the heat, it can have an impact on your septic tank if you are not properly prepared. During the rainy season, too much rain can flood the drain field and cause it to become saturated. In such a case, the effluent from the septic tank has nowhere to go but back to the septic system. As a result, heavy rains and floods halt the septic tank’s ability to treat wastewater from your home.

You may notice the first signs, such as slow-flowing water from drains and toilets, indicating that your septic tank system is in trouble. Furthermore, untreated water containing potential contaminants can flood your home and the surrounding area. However, there are some precautions you can take to protect your septic tank during the rainy season, which are discussed below.

Use less water

Excessive water use during the rainy season can put additional strain on the septic tank system. It may also prevent solids from settling at the bottom and force them into the drain field, resulting in pollution. As a result, practice water conservation, repair any leaking faucets, and, if possible, reduce the number of baths or showers you take per day. Convey the same message to any guests you may have.

Flush organic waste alone

Human waste and toilet paper can both be flushed down the toilet. Other products such as paper towels, diapers, wipes, sanitary napkins, facial tissues, and coffee grounds should not be flushed since they can overflow the septic tank and cause a blockage.

Avoid flushing chemicals

Avoid disposing of chemical-containing materials in the septic tank system, such as paints, solvents, and pesticides. Even medications should not be flushed. These will kill the beneficial microorganisms in the tank, which are responsible for decomposing the waste.

Manage rainwater runoff 

Direct or re-route the storm water runoff from roofs and other places away from the septic tank and drain field. If possible, pile up the soil over the septic tank system to force runoff away. Check that the area above the drain field is graded. It will keep excess water out of the system and protect it well.

Septic tank maintenance

Septic tank maintenance is essential for keeping the system safe during the rainy season. The ongoing maintenance schedule must be strictly adhered to in order to maintain peak performance in all seasons. It should reduce sludge buildup and prevent overflow problems, as a faulty septic system will cause more problems during the rainy season. However, many people are unable to do so because septic tank pumping services are prohibitively expensive. A better option would be to use biological septic tank treatment, which is a promising innovation and an affordable solution for septic tank maintenance.

Biological septic tank treatment entails the use of biological additives, which improve the performance and growth of existing microbes in the septic tank system. This, in turn, accelerates waste breakdown. Other advantages of biological additives include their ease of use, low cost, and suitability for routine septic tank maintenance. The use of biological additives also aids in the avoidance of costly mechanical maintenance.
