"桶槽的租费" can be translated into English as "rental fee for tanks/vats" or "leasing cost of tanks/vats".
"Rental fee" or "leasing cost" both convey the idea of paying for the use of something over a period of time.
"Tanks" or "vats" refer to the containers themselves, with "tanks" often being used for larger, industrial-scale containers, and "vats" also indicating large containers, especially those used in manufacturing or processing.
The choice between "tanks" and "vats" may depend on the specific context or the type of container being referred to. In many cases, either term could be used interchangeably.
