Home to four of the world's largest steam engines and an ASCE National Landmark and AWWA Landmark


Cincinnati Triple Steam, CTS, is a joint volunteer effort by Larry Moster, a retired employee of the Greater Cincinnati Water Works and volunteer Leland L. Hite (Lee).

We have done this site to preserve an important part of our industrial heritage that has significantly contributed to the success of making us who we are today.

Cincinnati Triple Steam is also a tribute to the men and women that have contributed to the effort by the Greater Cincinnati Water Works to provide a reliable, high volume and high quality water supply for the Greater Cincinnati area. The success of their effort continues today.

A special thank you to Ed Kispert, an employee of GCWW, who filmed these engines in the 1950's using 8 mm B&W film. If anyone else has film or pictures of these engines they would like to share with CTS & GCWW, please drop us an e-mail. We would like to include as much history as possible.

We do not necessarily assume that you know all the aspects of steam powered engines and large water pumps. Where appropriate we have added additional details in an effort to assist your understanding of the principles and terminology used for an operation of this size.

We have made every effort to respect copyrights and if you spot something we missed please let us know so we can correct the issue. e-mail.
