The City of Orlando’s Iron Bridge Water Treatment Plant. Bill Wood, Manager of the Industrial Automation Group, and Guy Mecabe, System Manager of Wastewater Systems, discussed their systems philosophy at the plant. The city owns and manages four large wastewater treatment facilities with associated remote pumping and lift stations. The Iron Bridge plant was originally built in the 1980s to treat about 5 million gallons of wastewater per day. After several modifications and upgrades, it can now treat and reclaim up to 40 million gallons in that same 24-hour period. The facilities standardized on Siemens controls, drives, power distribution, and Profibus and PROFINET communications network.
