Where should floor drains in a fuel loading dock area be plumbed to?

Floor drains in a fuel loading dock area should be plumbed to a pretreatment facility to ensure proper handling of any hazardous materials or contaminants that may enter the drainage system. Fuel loading operations can generate spills and leaks, which could introduce harmful substances into the water supply if not treated appropriately.

A pretreatment facility is designed to treat wastewater before it is released into a more extensive system, such as a public sewer or waterway. This facility removes pollutants to meet regulatory standards, protecting the environment and public health from potential contamination.

Plumbing drains directly to rainwater sewer systems, public sewer systems, or septic tanks would pose significant risks, as these options do not provide the necessary treatment for hazardous materials commonly associated with fuel loading activities.
