The District of Houston recently upgraded an existing telemetry alarm system to a full  SCADA System to remotely monitor the District's water reservoir, wells, and sewage treatment plant.

Dayton & Knight was responsible for this turnkey project that included the supply, installation, programming, commissioning, and training for the Motorola's MOSCAD Remote Terminal Units (RTU), Intellution's iFIX Human Machine Interface (HMI) and associated instrumentation at each remote facility.
 

With the implementation of the SCADA System, the District will improve services to the community. Six remote stations are currently monitored on a twenty-four hour basis.

When alarm conditions arise at these remote sites, the standby operator will be notified of the condition so the alarm can be corrected before major problems occur.

The configuration of the HMIs and programming of the RTUs provided operators with:

Data displays (such as reservoir levels, well levels, flows, etc.) in the same format as they appear at the field locations.

Automatic paging of standby personnel for priority alarms during and outside normal working hours.

Trend historical data that enables the District to collect and display process data.

Archived data can be used for documentation and for analysis to assist in decision-making.
