The Transdanubian Regional Waterwork Plc. (DRV) aimed to reconstruct its process supervisory systems and to develop a unified, integrated and complex process control system that covers the water production, water distribution and wastewater treatment activities in such a way that the particular sub-units are going to be closely integrated to each other.
The realization of the envisaged work doesn’t only consist of connecting the hardware and software systems but it rather foresees the implementation of a comprehensive system that aggregates the software, hardware, data bases and services.
Based on the consultations with the experts of the Transdanubian Regional Waterworks Plc., in order to achieve the modernization goals of the system, the following developments were carried out by us:
- Establishment of a corporate level water and wastewater dispatch centre. The creation of an integrated system, instead of ‘’island” system.
- Using the advantages of internet/intranet technologies that can have an effect on the duty system, maintenances and the creation of operation management schemes, since it assures that information is available everywhere at any time. This technology also makes the informatic operation of the system easier, since it allows a simple change of version and client-side installation is not necessary.
- The establishment of such territorial/regional dispatch centres that can be moved freely within the network of the corporation, as a consequence of which the operational control system can follow the changing organizational structure in a flexible way, it can be modified quickly based on the changing needs.
- It is necessary to deploy process control systems that are developed in an integrated way, including a uniformed user’s surface, management, functionality and control. In this way a solid system can be developed, in which the employees of the corporation can find their way easily and can access every information that is necessary during their work, shall they stand at whichever level of the organizational hierarchy.
- Integration to the Technical Information System (TIS) in order to reduce duplicated working activities and errors. As a consequence of this, the huge amount of data that is generated in the process control systems and serves as a basis for the TIS is directly passed over to the latter in a controlled way.
- Connecting data sheets to machines and objects
The project implementation lasted for 2 years, the extension of it is indicated by the figures below:
The integrated process control system for wastewater services at DRV Ltd.
- 1.400 objects in total, connected into a unified integrated process control system out of which 800 are wastewater facilities.
- Hungary’s largest process control system for wastewater utilities (2010):
- In 6 counties.
- Sewage services for 435.000 inhabitants.
- 145.000 m3/d of wastewater treatment capacity.
- 32 wastewater treatment plants.
- Over 700 wastewater pumping stations.
- 3230 km sewer network.
- 15 wastewater sub-centers and a corporate head office.
Integrated process control system for potable water services at DRV Plc.:
- 1.400 objects in total, connected into a unified integrated process control system out of which 600 are potable water facilities.
- Hungary’s largest process control system for water utilities (2010):
- In 6 counties
- Potable water services for 370 settlements.
- 418.000 m3/d water production capacity.
- 6008 km water distribution network.
- 4 potable water sub-centers and a corporate head office.
The process control system has been created on a webSCADA platform.
