Will building a house extension affect my septic tank / sewage treatment plant?

House extensions are a common way to increase living space and add value to a property. However, when considering an extension, it is important to take into account how it may impact your septic tank or sewage treatment plant. In this blog post, we will explore the potential effects of a house extension on your system and discuss what you should consider before starting your building project.

Size of septic tank / sewage treatment plant

One important thing to keep in mind is that the size of your septic tank or sewage treatment plant is designed to handle a specific amount of wastewater. If you add more living space to your home, you will likely also increase the amount of wastewater generated, which can overload your system.

Proximity of septic tank / sewage treatment plant

Additionally, you should consider the location of your system in relation to the proposed extension. If your extension will be located near the septic tank or sewage treatment plant, it may not comply with regulations. In this case, changes to the extension may be required, or a new system installed at an alternative location.

Condition of septic tank / sewage treatment plant

Another important factor to consider is the age and condition of your system. If your system is already near its capacity or is in need of repair, adding an extension to your home could exacerbate any existing issues.

Upgrading of septic tank / sewage treatment plant

In some cases, upgrading the system may be necessary to accommodate the additional wastewater generated by the extension. This could include installing a larger septic tank or upgrading to a more advanced sewage treatment plant.

Compliance of septic tank / sewage treatment plant

Finally, it is important to consider any regulations that may impact your system. Therefore, it is important to check with local authorities to ensure that any modifications to the septic system are in compliance with local regulations.

In conclusion, when planning an extension, it is important to consider the size and location of your system, the age and condition of your system, and any local regulations or building codes of practice. By taking these factors into account, you can ensure that your extension does not cause any issues with your system and you can enjoy your new living space with peace of mind.
