State and county sewage control regulations require that either a licensed OSS designer or Registered Professional Engineer design your OSS. The state issues Licenses for Designers and Engineers.
Whatcom County code requires that all OSS be installed by a licensed OSS installer; however, if you are the property owner and you will live in the home the OSS will serve, you can request an exemption from certification requirements. The request will be reviewed and if approved, you can install the OSS. We recommend that you hire a Licensed OSS Installer for complex systems, e.g. pressure systems or alternative systems.
Developers must hire a Licensed OSS Installer or obtain an OSS Installer's License through the Health Department to install OSS on properties they plan to develop and then sell.
