$21 m contract to renew equipment and replace outdated technology

Monday, 14 July, 2008

Norfolk Group Limited, a provider of integrated building and engineering services, has been awarded a $21 million contract to upgrade the SCADA and Telemetry Control (known as IICATS) on Sydney Water Corporation’s Illawarra and Prospect water and wastewater system.

The 80-week project will see Norfolk's wholly owned company O’Donnell Griffin carry out work at 70 wastewater pumping stations and 66 water pumping stations in the Illawarra and Prospect regions. The contract entails:

  • Renewing equipment in the Illawarra Water and Wastewater System with Integrated Instrumentation, Control, Automation and Telemetry System (IICATS) technology that will deliver a single integrated system with all sites connected directly to the metropolitan IICATS system;
  • Replacing outdated technology with standard IICATS at Prospect Water Filtration Plant sites.

Sydney Water operates IICATS, which presently monitors and controls over 1450 facilities, including water sites, wastewater sites, overflow monitoring sites and pressure monitoring sites.

IICATS encompasses instrumentation, control equipment and site-based remote terminal units, which all communicate over a Wide Area Network with centralised Telemetry Computers and workstations to provide advanced operational monitoring and control of the remote Sydney Water assets.

The main Metropolitan IICATS system, comprising some 1300 sites, was delivered in a number of stages between 1995 and 2003 and provides a common set of design standards to simplify and optimise site design, operation and maintenance.
