Homeowners who use septic tanks to safely process and dispose of the waste generated in their houses need to understand the importance of regular maintenance. A failing system doesn’t just limit plumbing capabilities, but it also makes expensive septic repairs much more common. This becomes especially true in times of heavy rains, which is why sanitation service professionals recommend minimizing the risk.

Why Rain Affects Septic Tanks

Two essential parts of a septic system are the tank and leach field surrounding it. As waste travels from the home into the septic tank, it is broken down by the enzymes and bacteria found inside. Once sufficiently processed, the partially treated water drains out of the tank into the surrounding soil where it is fully treated.

With heavy rainfall, however, the water can’t drain into the leach field because the ground is overly saturated. This causes the tank to fill up, and the untreated wastewater will work its way back through the plumbing and into your home. If this happens, pathogens can pose a health risk to your family and pets. The sewage could find its way into any groundwater and pollute it.

How to Prevent Septic Tank Problems

You can’t control the weather, but there are ways to avoid septic issues. One crucial task is to schedule regular septic pumping every three to five years; this may need to be sooner if you have a larger household. This removes the built-up waste and frees up space inside the tank.

If your area has heavy rainfall, cut back on water usage. This lessens the amount that is processed by the tank. Don’t add chemicals into your plumbing during heavy rains; these throw off the balance of enzymes and bacteria inside the tank and make them less efficient at processing waste.
