What To Expect During Septic Tank And Drain Field Repairs

The septic tank and drain field that make up the average home's septic system may seem mysterious, but they are surprisingly simple in design. But because they are buried under the soil near the perimeter of the house, many homeowners may have only a vague idea of what these components look like and their actual dimensions.

This lack of information can make it difficult for the uninformed homeowner to know what they can expect during any septic tank or drain field repairs that they may need to have done. If you are having part or all of your home's septic system repaired, this information will help you better understand what to expect. 

Repairing a septic tank

Most septic tanks manufactured today are extremely durable and designed to last for several decades. Occasionally, however, one will malfunction or develop a leak and require repairs. If the leak cannot be repaired, such as when the tank is an older metal tank that has become corroded, it will need to be dug up and replaced. 

If the leak is a small one, such as one that might occur at a joint, connection, or seam, homeowners can likely expect the tank to be partially exposed so that it can be properly patched or repaired. 

Whether the septic tank is being repaired or replaced, the raw sewage and effluent inside will first have to be pumped out before the work can begin. 

Repairing the drain field

Repairs to a drain field may include repairing or replacing damaged pipes and connections. Some common causes of damage to the lateral lines and connecting pipes of a drain field include crush damage from the weight of vehicles, livestock, or heavy objects on the site that cause compaction of the soil. 

Drain fields that have failed and can no longer efficiently process the effluent from the septic tank may require complete replacement. In cases of partial failures, one or more of the lateral lines may need to be replaced.

Homeowners whose families have grown significantly since moving into the home may also find that they need to enlarge their drain field to handle the additional load. If the septic tank is too small, homeowners can either choose to pump the small tank frequently to prevent overfilling or have the small one replaced with a larger one.
