Czechia – Command and control system – Modernizace řídících systémů čistíren odpadních vod a čerpacích stanic odpadních vod

The subject of the public contract is the replacement of existing programmable logic controllers (PLCs), the addition of communication media for bidirectional data transmission, the modification of existing switchboards or the supply of new switchboards, the modification or replacement of existing hardware (HW) and software (SW) elements for data visualization, archiving and backup. The implementation will be carried out in connection with wastewater treatment plants (hereinafter “WWTPs”) and pumping stations (hereinafter “PSs”) on sewerage networks, whereby the implementation of the public contract will result in the unification of HW, SW, control algorithms and communication between individual communication elements and nodes. Communication must be reliable and functionally separated from other networks, i.e. the separation of the information technology network (IT) and the operational technology network (OT) so that they cannot be subject to cyber threats. The subject of the implementation includes the processing and delivery of documentation of the actual implementation in electronic form and further indefinite servicing services (the proposal of the conditions of the servicing services will be submitted by the participant in the next phase following the invitation to submit preliminary tenders and may be the subject of negotiation if it concerns the conditions and scope). Further information is provided in the tender documentation.
