Which law enforcement department manages hotel sewage discharge?

First, your sewage discharged to different ways (generally divided into natural water bodies and municipal pipe networks) needs to meet different discharge water quality requirements. The supervision and law enforcement department of this requirement is the supervision department of the local environmental protection bureau.

Secondly, if the municipal pipe network is involved, you need to contact the local municipal department (you have to pay a certain network access fee).

Thirdly, there are two kinds of daily charges for sewage discharge, one is the sewage charge charged by the environmental supervision department, and the other is the urban sewage treatment fee charged by the water department. Generally, sewage discharged up to the standard is no longer charged with sewage charges.

What's more, I don't understand what you mean when you say that the Water Affairs Bureau allows the installation of sewage treatment pumps. Sewage treatment is not under water management. Also, does the sewage treatment pump mean the lift pump? If your hotel sewage treatment is too low to be discharged into the municipal pipe network, you need to set up a lift pump, but this seems to be a matter of consultation with the municipal department and has nothing to do with water affairs.
