The Clemark AutoTreat control system for effluent plants is a comprehensive SCADA package with a custom built control panel, a plant control processor (Motorola 68000), and PCs for operator interaction and for management information. A typical control panel mimic display is shown in the picture on the right. The control panel serves as the interface between the plant and the various processors, but performs no function other than as a conduit for data and operating signals. Each system is custom built, with typical functions provided by the other components displayed on clicking their names below.

Clemark provides the software and the hardware for all components. Clemark installs the system, trains user staff in its use and provides ongoing support by telephone and by direct connection through modems between each user's system and Clemark offices.
