Water Management Services use OPC UA

    The City of Enid, Oklahoma is located 70 miles North of Oklahoma City. The city’s water management services include production, distribution and reclamation. The Water Production department is responsible for the maintenance and operation of the water collection system, and treatment plants. The water is treated, tested, metered and monitored to meet the most stringent requirements set down by the State Department of Environmental Quality, the Federal Department of Environmental Quality and the Federal Environmental Protection Agency.

    The collection system serves about 50,000 residents, with an average of 11 million gallons daily and peaks of 20 million in the summer. It includes approximately 140 producing underground water wells with 200 miles of collection lines, 23 million gallons of storage tanks, seven pumping stations and two treatment plants. The department operates seven days a week to produce safe, potable water for residential, commercial and industrial customers.

    In addition to ICONICS’ GENESIS64™ HMI/SCADA software, the City of Enid selected ICONICS’ OPC Server Suite, which supports both OPC UA and OPC DA connectivity.

    Following a 60-day development cycle, the department initially used their new ICONICS software to design and implement their new Water Production control system. The goal was to standardize on the selected software and provide an interface with ease of access for all operators. Using GENESIS64 resulted in an exact 3D view of remote stations and pump rooms. The department’s new system handles over 1,400 tags in its Water Production system, which now integrates with their Koyo PLCs. The ICONICS software also ties into additional hardware including wireless, serial and networking connections (e.g. UHF, VHF and FSK [Frequency Shift Key]), bringing the system into the Internet of Things. The department wanted a solution that easily integrated with OPC UA technology and standards, which is now handily provided through ICONICS’ OPC Server suite.
