Fresh Water & Wastewater Control Systems ---

A main focus of Systems Interface is the support of municipal water districts by providing high quality, economic control systems for wells, lift stations, reservoirs, or wastewater treatment facility’s.

Our experience encompasses all manner of communications, including land line, cell phone, radio and satellite. Systems are designed according to the needs of the water district to provide reporting, alarming, data analysis and are designed to be expanded as the water districts needs grow and expand.

Systems Interface designs and delivers both fresh water and wastewater control systems around existing infrastructure. We also provide upgrades to existing equipment to provide better communication or control capabilities as required. A typical system will consist of Rockwell Automation or Siemens PLCs, Ethernet-based Remote I/O, Fiber Optic Networking, Operator Interface Touchscreens, and Industrial Automation software using for reporting, archiving, trending and alarming.
