Project Description:
The City of Allentown Water Treatment Plant is a 40 MGD plant that treats water from the Lehigh River providing high quality potable water to the residents of Allentown, PA.

Transdyn built a distributed control system consisting of 10 distributed, redundant controllers communicating via a redundant, fiber optic Ethernet network to redundant servers and distributed workstations located throughout the facility. The system manages all aspects of plant operation including raw water intake, sedimentation, chemical pacing, filtering, and finished water storage and pumping. The plant was commissioned and placed on-line in January 1998.
