Attention: open in a new window.

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.
