The Upcoming Tours

Make a tour Reservation:

The first tour of our this RESC season is now set for Thursday, October 20th from 1 to 3 pm.

This tour is of the Richard Miller Treatment Plant (RMTP), part of the Greater Cincinnati Water Works (GCWW) owned and operated by the city itself, with focus on a new ultraviolet disinfection treatment system. Construction of the system was started in Nov 2010 and completed in Oct 2013. Apparently it's the largest utility in North America to use this additional UV light treatment step after conventional coagulation/sedimentation/filtration and then activated carbon filtration.

Further detail is available on the web by googling richard miller treatment plant. Note that Lee Hite co-authored a 2015 article on this plant that traces the history of the facility. Very interesting background! Another co-author of that 2015 paper (published in the American Water Works Association Journal December 2015) is Lawrence Moster (Assistant Superintendent of GCWW Supply Division) who will be our tour guide.

Please signup on the RESC website (preferred) or at the October 18th luncheon meeting.

The Upcoming Planned Tours for the 16-17 activities year are

CVG Behind the Scenes (November)

Kroger Food Plant (March)

Metalex (May)

These are tenative plans and are subject to repeated changes. Be sure to check back here for the latest information.

Now is a good time to let the tour director know of any places you believe would provide an interesting tour. Including a contact would be helpful.
