water feed + test point |
chiller lines |
leak detector |
A properly engineered "data center" does not have water pipes running overhead. (other than fire suppression, as I told one building engineer, "if there's water coming out of it, then my stuff under it is
on fire.")
That said, the one we inherited (built a decade ago) does have a water line overhead -- the feed to humidifiers -- and huge water pipes from the building chiller
under the floor. (and yes, there are leak detectors. and a floor drain.)
