Te-Tech Process Solutions in collaboration with TCS (Tata Consultancy Services) delivered the site wide SCADA upgrade at Eastney WPS for Southern Water.
The project required the installation of a new site wide fibre network and new SCADA server. The new integrated Wonderware InTouch SCADA system replaced all existing SCADA/HMI components to provide a single site-wide SCADA system.
At the Eastney site, the PLC hardware is predominately of two variant types, these being:
- GEM80/131 and GEM80/400s
- Allen Bradley SLC 5/05s
These were replaced with the Allen Bradley Control Logix platform.
The proposal was to re-engineer a like-for-like functionality of the existing GEM80 / Imagem and SLC5/05 control system with modern PLC and SCADA technology. These were compliant with Southern Waters MEDs as far as is practicable and future proofed the sites SCADA and PLC network.
When the upgrade was completed, it provided a reliable and compliant foundation for any future changes or enhancements.
Commissioning comprised a rolling programme over a period of 12 months, phased by process area in order to manage risk.
