Industrial switches and hubs network treatment Plants in Springfield
The City of Springfield Missouri maintains two Wastewater Treatment Plants. The water treatment plants are 24x7 operations that together collect and treat 39 million gallons of wastewater generated daily by the citizens of Springfield and Greene County. The Southwest Plant is the larger of the two, with a capacity to treat up to 42.5 million gallons per day. The Northwest Plant can treat up to 6.4 million gallons per day.
The Wastewater Treatment Plants needed to expand their SCADA systems. Only two buildings on the nine-building Southwest Plant site had in-building networks, and none of the buildings were interlinked. In addition, there was no network link between the Southwest and Northwest Plants, and the city’s plans called for a more integrated system.
The Southwest Wastewater Treatment Plant contacted R. E. Pedrotti Co., Mission, Kansas, to assist in designing a solution. The Pedrotti company has been providing total packages for water and wastewater treatment plants for more than 25 years.
The Pedrotti company explored existing products for industrial environments and recommended the GarrettCom Ethernet product line. The breadth of the products and their built in fibre ports reduced the requirement for extensive numbers of media converters to connect existing copper-media equipment.

AMR Corp taps GarrettCom for industrial Ethernet in aircraft maintenance
AMR Corp has been making use of Z-Technologies’ process control expertise for many years. When plans called for creating a profit centre, Z-Tech helped the facility develop a system to collect and communicate information on each job for the IT department. The initial plan was to maintain the legacy Ethernet system using GarrettCom’s 3000X Series Hubs. This bus-oriented implementation ran at 10 Mb using BNC connectors and cabling (an older Ethernet cable type) and fibre. Media converters were used to integrate serial lines.
The final solution takes advantage of the in-place fibre loop to leapfrog to current-generation 1 Gb backbone bandwidth capability including port modularity, network management software, and resilient ring structure support – all for less than a 10% increase in investment over the 10 Mb legacy concept
A combination of 6K25 and 6K16V managed switches, which support Ethernet bandwidth from 10 Mb to 1 Gb, provides the backbone for the facility. The network is currently utilizing a 100 Mb backbone; it can upgrade at any time using plug-in modules. The modular ports capability and the fibre built-in features of the 6Ks made them an ideal fit for the job.

Sacramento Department of Utilities chooses 6K25 switches for Water Treatment Plant
The Sacramento River and E.A. Fairbairn Water Treatment Plants (established in 1964) account for 85 percent of Sacramento’s water supply. The Sacramento River Water Treatment Plant’s current intake structure was out of compliance with current environmental standards. As a part of the modernization project, CSDU (City of Sacramento Department of Utilities) chose to update its networking system as well. In developing the upgrade plan, CSDU wanted to use state-of-the-art technology that ensured a platform from which future upgrades could be expected to be integrated easily.
The new installations are based on a redundant ring topology, and utilise fibre media to support the distances required in managing the various SCADA (Supervisory Control and Data Acquisition) systems located throughout the City of Sacramento. The EMI noise immunity of fibre cabling increases operating reliability of the network. The installation uses the less expensive copper cabling for some local devices and computers within control system racks. Cost was an issue as the CSDU wanted to make its funds stretch as far as possible in upgrading the system.
INS recommended the 6K25 fibre switches and INS’ iSNMP (industrial networking management protocol) Network Management Software. The 6K25 took advantage of GarrettCom’s unique modular port structure that enables customers to define on a port-by-port basis the medium they need to use, providing immediate cost savings because of the efficiency of the units, and eliminating the need for media converters.
