The subject of the tender and the subsequent award of the contract is the renewal of the process control technology in all three waterworks operated by MVV Netze. The individual plant locations are the following:

- Wasserwerk Mannheim-Rheinau, Hallenweg 101-104, 68219 Mannheim

- Wasserwerk Mannheim-Käfertal, Wasserwerkstr. 283, 68309 Mannheim

- Wasserwerk Schwetzinger Hardt, Heuweg, 68723 Schwetzingen

Groundwater is extracted from the three waterworks for drinking water supply. It has been classified as critical infrastructure.

MVV NETZE wants to start replacing the outdated control system with a future-proof and at the same time innovative SCADA system. This updated control system must also comply with the KRITIS requirements according to the international standard IEC62443 "Industrial communication networks - IT security for networks and systems".

Particular attention is paid to compliance with requirements for compliance with OT security in accordance with the KRITIS Act. There is an ISO 27001 certified ISMS in the water sector.

For MVV Netze, it is essential that the drinking water supply is always secured. For this reason, the necessary approaches to modernization during operation are discussed in detail. The aim is to avoid operational disruptions and the associated interruptions in the drinking water supply and thus ensure the supply task of MVV NETZE.

MVV NETZE intends to introduce a future-proof and at the same time innovative SCADA system for drinking water supply. This project includes the modernization and renewal of the control and automation technology.

In this implementation stage, however, only the control technology level OT is considered, i.e. red. host systems, WinCC, network components/structures and all components that are necessary for the implementation of the requirements from the KRITIS consideration.

The introduction of an updated control system is urgently needed because the control system used so far is no longer state-of-the-art. Ensuring that the high demands on IT security gm. KRITIS law highlighted; In addition, many system components have been discontinued and are no longer subject to maintenance and care.

For these reasons, the control and automation technology should be updated as quickly as possible. It should be noted that the supply of the population with safe drinking water must not be endangered at any time during the conversion period.

Since the updated control system has an expected lifetime of the system of at least 12 years, current and expected innovations must be taken into account in the system design. In this context, the opportunities and possibilities of digitization must be taken into account. Although digitization is now classified by almost all important representatives of the industry as an important field of action for the immediate future, "only" individual aspects or applications are usually considered in the concrete implementation. A holistic approach is expected here and is also described accordingly in the service specification and the bill of quantities.

It follows from the above-mentioned boundary conditions that the updating of the control technology is a technically and organizationally highly demanding project that places high technical, economic and structural demands on the implementation.

In order to meet the increased requirements in terms of OT security, it is imperative to update the existing control software. Likewise, the hardware and operating system of the system components must be brought up to the state of the art. The requirements also result in some adjustments to the system software that must be implemented in the course of the migration.

Before submitting an offer, an on-site appointment at one of the locations is recommended.
