Portsmouth Water has made a single supplier direct contract award for GEO SCADA WITS migration worth ££525,633 (inc VAT) to Schneider Electric Systems UK Ltd.

Portsmouth Water Ltd currently communicates with its T4 type RTUs using the existing telemetry protocol.
As the existing telemetry has reached end-of-life with limited support available, the utility now needs to use the Geo SCADA DNP3 WITS driver to communicate with each of the existing T4 type RTUs following their conversion from running the Proteus firmware to running the T4 DNP WITS firmware.
Following on from a detailed study of the water company’s database, and investigation into options, Schneider Electric Systems UK have identified a tool that will allow a user to select any outstation on the existing database for automatic conversion of its associated database objects to supported standards (DNP3 T4 WITS database objects) except for logic Charts.
The scope of the contract delivery covers the design, development and testing of software tools to support the database conversion process, as well as the creation of Method Statements that detail the steps to be undertaken by Schneider and Portsmouth Water on their site system.
The scope includes all 72 RTUs including addition RTUs (from critical sites) in the factory/ testing phase and additional site engineering scope as follows:
- Simple complexity Outstation - point counts less than 100 - 42 RTUs in total
- Average complexity Outstation - point counts between 100 and 300 - 21 RTUs in total
- Complex Outstation - point counts greater than 300 - 9 RTUs in total
The new scope of work is to migrate all 72 of these RTUs over to the WITS protocol using the tools and methodologies developed..
Earliest date the contract will be signed is 7 November 2025 following the conclusion of the standstill period on 3 November 2025.
Estimated start and end contract dates are 7 November 2025 to 31 December 2026.
Portsmouth Water has made the single supplier award for technical reasons on the basis that there is no feasible alternative to Schneider providing the upgrade services.The water company has currently implemented the Schneider GeoScada platform which is integrated into its existing water supply and treatment control network. The software is owned and licensed by Schneider who have the necessary tools, access and security controls to upgrade and modify the platform.
