I have a septic system and would like to add an additional bedroom on my house. Do I need to do anything to my septic system?

Adding an additional bedroom will not significantly increase the waste flows for your home. Therefore, the ECDOH would not require installation of a new system or modifications to your current system at this time. However, please be aware that if you decide to sell your home the ECDOH will only certify the home as having the original number of bedrooms since that is the current sizing of your septic system. If you plan to sell your home using the additional bedroom then a new septic system may need to be installed. For more information, please call the ECDOH at 716-961-6800.
