Not sure if this applies everywhere, but in Ohio, we had to get permits with City Water/Sewer to allow us to discharge the one pass water down the drain, so there is that extra paperwork and inspections to show that it was coolant water that was isolated from anything hazardous, and we had to estimate the daily use.

That may not be relevant for somewhere as large as UC Davis, but for a small company, it was a measureable percentage of our water use.

Subject: [DCHAS-L] One Pass Water Flooding Incidents

Hi All:


I have a couple of hold-outs who insist on using one-pass water in reflux condensers and the like.  The "California is in constant drought" argument gets me nowhere.


So I'm looking for flooding incidents when the tubing popped off the condenser and flooded the lab or building, etc.  Images would be awesome.
