Tips For Replacing The Septic Drain Field

Posted on

Replacing a septic drain field is not easy; expect to spend anything from $2,000 to $10,000 on this project. Thus, you need to get everything right from the beginning so that you don't waste money. Below are a few tips to help you with the replacement.

Proper Design

The design of the septic drain field determines not only its longevity but also the efficiency of the septic system. An improper design increases the risk that your septic system won't be able to handle all the wastes from your house.

The volume of wastes from your house plus the percolation rate of the drain field are some of the biggest factors to consider. The percolation rate is the speed with which wastes are absorbed into the soil. You need to match the volume of wastes and percolation rates so that wastes from the tank get absorbed into the soil within a reasonable time.

Local Regulations          

Septic systems are some of the most tightly regulated things in the building and construction industry, and there are several reasons for this. For one, septic systems are dangerous since they contain germs. Secondly, a mistake (with a septic system) might affect not only your home but also your neighbors' properties (for example, by contaminating groundwater).

Therefore, before the project begins, you must liaise with the local authorities and understand all the applicable laws. Don't rely on the regulations that existed during the installation of the now-defunct septic drain field because building codes get updated all the time. For example, you must know how far the drain field should be from your home boundary and how large the drain field must be for your home's size.

Future Considerations

Lastly, you must also site your drain field, taking into consideration future changes to your home. For example, don't place the septic drain field somewhere you plan to plant trees in the future since the tree roots might interfere with the septic system. If you plan to sink a well or construct a parking lot in the near future, you should ensure the septic drain field is located far from them. Otherwise, the septic drain field might fail and require relocation again. If you plan to extend your house or grow your household, design the drain field with those expansions in mind.

Sit down with a septic technician to help you go through all these and more factors. The technician can then advise you on what you need to do to get a dependable septic drain field.
