Why Is My Septic Tank Backing Up When It is Raining?

Sunday, June 24th, 2012

When it rains there are several things to consider to help your septic system endure during these times. First of all have your septic system maintenance prior to the summer rains. Make sure the septic system is completely sealed with septic tank risers and lids that create water tight connections. A leaking septic tank can allow rain water and roof runoff enter the septic tank and wash solids into your drainfield. This can cause a premature failure of your septic system and cause the septic system to back up in the house.

Making sure that roof gutters and downspouts are directed away from your septic system is imperative. This will eliminate excess water from entering the system and allow your septic system to function properly. If the septic tank is older than 10-15 years old you need to have the tank checked for leaks and structural integrity. As concrete ages there can be cracks and structural problems that can occur. In times of rain events and where the water table is high can change the functioning of the septic system.

Rain water can take up drainage space where your drainfield usually drains out. As the water table comes up and there is more rain then there is nowhere for water to go except back into the house. A drainage plan can be developed to ease stress placed on your septic system from rain storms.
