Renovation of a water / sewer project in Lethbridge, Alberta. Completed plans call for the renovation of a water / sewer project.

The City of Lethbridge Wastewater Treatment Plant (WWTP) and Water Treatment Plant (WTP) SCADA systems will no longer be properly supported (Microsoft Server 2012) in 2023. The City of Lethbridge is looking for a SCADA system with an intuitive developer interface which is secure, easy to enhance and upgrade. The software should be supported in a way that eliminates the need for planned major overhauls due to peripheral software obsolescence. Future planned system enhancements include expanding the capabilities of our data historians, engineering systems, network architectures, and callout procedures. To enable the upgrade, the City of Lethbridge is requesting pricing for SCADA software which meets the outlined requirements. A system integrator may be hired to work alongside existing plant staff to complete installations and modifications of the procured software. The future WWTP SCADA system demands are as follows: 3 x redundant full installations utilizing self-contained desktop pc's (includes 3 development station) 5+ thin clients 10,000 tags 10,000 tag runtime for view only purposes The future WTP SCADA system demands are as follows: 3 x redundant full installations utilizing windows servers (includes 2 operations station and development station) 5+ thin clients 10, 000 tags Server 10,000 tag runtime for view only purposes The proposed WTP future system architecture will include redundant servers, two operation work stations, a single development workstation, and a read only server outside of the system firewall for data querying.
