Which interceptor should all commercial garage drains connect to?

For commercial garage drains, they should connect to a Type I interceptor. This type of interceptor is specifically designed to handle the unique waste generated in vehicle maintenance and repair areas, which includes oils, greases, and other hydrocarbon pollutants that may be present in the wastewater. The primary purpose of a Type I interceptor is to separate and retain these contaminants before they can enter the public sewage system, thus ensuring compliance with environmental regulations and reducing the risk of contamination.

Type I interceptors have a larger capacity for collection and are equipped with features that facilitate the removal of trapped contaminants efficiently. They are essential for protecting the environment and maintaining proper sanitation within commercial garages. Understanding the function and application of Type I interceptors is crucial for plumbing professionals to ensure safe and compliant facility operations.
