ISA symposium attendees are invited to attend the tour of Toho Water Authority’s South Bermuda wastewater treatment plant, located South of the City of Kissimmee on the northwest side of Lake Tohopekaliga. The plant is a Class I reliability plant with a permitted capacity of 13.0 MGD and a buildout capacity of 21.0 MGD.

The treatment methods at this facility include preliminary treatment, primary clarification and grit removal, secondary biological treatment anoxic/oxic/anoxic/oxic, secondary clarification, filtration with disk filters, and disinfection with chlorine.   Construction of this facility was completed in early 1988. Since then several expansions have taken place to increase capacity.  Other additional improvements include multiple upgrades to the collection system and a bio-solids treatment expansion consisting of mixed holding tanks, belt filter press dewatering, and sludge cake disposal.  Effluent from the plant is disposed of either as reused irrigation or at a Rapid Infiltration Basins (RIBs) site in western Osceola County.

The plant SCADA system is comprised of Allen-Bradley PLCs and an iFIX HMI system and the South Bermuda facility also includes Toho Water Authority’s central control room.

On your tour you will have the opportunity to:

  • Learn about the plant SCADA system
  • Learn about the plant treatment process
  • Visit several process areas
