Can septic tanks fill with rainwater?

With the record-breaking rainfall, many people are wondering if septic tanks can be filled with rainwater. Unfortunately, the answer is yes; a septic tank can fill up with rainwater. However, some precautions must be taken to prevent this from happening.

The first step that should be taken is to determine whether or not a septic tank can overflow during a rainstorm. This process starts by measuring the size of the inlet and outlet pipes of a septic tank. Once these measurements have been noted, compare them to each other. If the outflow pipe is smaller than the inflow, then there is the possibility that water could back up into a pit from a storm.

If a septic tank does overflow, it is essential to clean the system out immediately. This should be done with a hose. Ensure that all of the water from the storm flows out of the tank and into the drain field. If this doesn’t happen, it can cause problems for a person’s yard and surrounding areas.

Most septic tanks cost anywhere from $2,000 to $4,000 to have pumped out and cleaned. This is a service that should be left for professionals. These workers have the proper tools and knowledge needed to prevent problems from occurring. Septic tank companies also offer different sized tanks for a person’s size home.

Having the right size tank is vital to prevent issues from occurring. If a septic tank is too small, then it may need to be emptied more often. If this does happen, then the homeowner will end up paying higher fees for pumping and cleaning. 

Even worse, if a septic tank is too large, some problems could arise. Not only would this cost more money, but issues with sewage backup could occur.
