ちょっと専門的になりますが
ビルの給水は水道本管から一旦受水槽に入り

This is a bit technical, but
the water supply to the building first enters the water tank from the water main,

where it is sent to each floor.
The associated pump, solenoid valve, and various alarms are operated by the length of a stainless steel rod inserted in the tank.
