SCADA (Supervisory Control and Data Acquisition) combines technologies that collect data and control equipment in remote locations. New telemetry systems have given water and wastewater system operators flexible, cost-effective tools to manage systems controlled and monitored from central locations. These technologies also help owners avoid the expense of leased lines and the reliability problems associated with multiple telephone companies transmitting signals between or across service territories.

The firm has worked extensively with Distributed Control, groups of computer controllers integrated into a single virtual system. MWY's SCADA and Distributed Control experience is unique among firms of comparable size, particularly in regard to our in-house systems design and specification capabilities, which ensure both cost savings and compatibility between control systems and treatment processes.

MWY projects utilizing Distributed Control technology include:
1. Bentonville, Arkansas wastewater treatment plant using wireless Ethernet
2. Bentonville, Arkansas liftstation monitoring SCADA wirelessly using cellular Internet technologies
3. Carroll-Boone Water District water treatment plant using fiber optic Ethernet
4. Clarksville, Arkansas water treatment plant using fiber optic Ethernet
5. Conway Corporation water and wastewater treatment plants using fiber optic Ethernet and wireless Ethernet utilizing 900 MHz spread spectrum data radios
