Metasphere Case study: Regional Water

Company Ruse, Bulgaria: District Metering Areas (DMA) System


Metasphere Case study: Regional Water
Contact

  • Since implementing a DMA System, the Regional Water Company Ruse has achieved the largest reduction in water loss due to leakage of any other water company in Bulgaria.

  • The new DMA System provides valuable data on the network, enabling optimum use of technology and smarter investment and resource planning.

  • It performs automatic data collection from remote locations, consumption analysis and visualisation of results, providing accurate operational information for relevant departments and management.

  • Alerts enable the quick identification of incidents in clean water distribution and identification of leakages.

  • Fast and effective repairs can be undertaken on the basis of alerts received; minimising wastage of resources and loss of supply to customers.

STAKEHOLDERS

The Regional Water Company of Ruse is 51% State owned and 49% municipality owned and serves a territory of 2800 km2, and a population of 275,000 inhabitants. It is responsible for the operation and maintenance of a water supply and sewerage system in the municipalities of the Ruse region of Northern Bulgaria.

Industrial Systems for Automation (ISA) Ltd. is a consultancy and engineering company, specialising in the field of control automation, information and communication applications. ISA is a distributor and engineering partner of Metasphere.

BUSINESS NEEDS

The Regional Water Company of Ruse was experiencing high levels of leakage and a resulting water loss. Its water distribution networks and assets were being managed in a reactive manner and the company needed a solution that would enable the quick identification and reporting of leakages.

SOLUTION

The design, installation, system integration and commissioning of a District Metering Areas (DMA) system for the water distribution network, with zonal flow calculations, analysis, leakages and losses identification and reports.

The first 3 phases of the project cover 60 monitoring points and over 100 DMAs. The equipment at each monitoring point includes mechanical water meters/electromagnetic flowmeters/ultrasonic flowmeters and Metasphere’s battery-powered Remote Telemetry Unit (RTU), Point Orange with external antenna, capable of providing operational functionality for collecting flow information at locations without power supply from the grid.

Point Orange is a compact Logger/RTU device with integrated battery, IP68 unit enclosure, tri-band 3G/GPRS modem, internal and external antenna options, software configurable AI, CI, DI, Modbus and SDI-12 communication options with intelligent transmitters. There is an integrated submersion sensor, local diagnostic points and intelligent alarm reporting. It communicates with Metasphere Master Control System, DNP3 masters or FTP servers.

The pulse outputs of the mechanical water meters/electromagnetic flowmeters/ultrasonic flowmeters are connected to the counter inputs of Point Orange. The measured values are sampled and stored with time stamps at periodic intervals of 15 minutes.  ISA provided a software solution for zonal configuration, flow calculation and water consumption analysis, table and graphical reports, based on Metasphere’s telemetry platform. This software system was installed on a server at the client’s operational headquarters.

The software system is based on DNP3 OPC server for DNP3 Master functionality, OPC client, SQL server and application software. Microsoft SQL Server is implemented as a relational database management system for storing and retrieving data, providing an interface to third-party software systems. Data communication is based on 3G/GPRS and DNP3 protocol, configured for a daily communication session. The structure of the system allows remote reconfiguration of the RTU.

BENEFITS

The implementation of a DMA System has shown very good results; reducing leakages and water loss. It has proven to be an attractive solution for the quick identification and reporting of water distribution problems, temporal and geospatial flow and water consumption analysis and modelling.

Additionally it has improved operational activities such as preventive maintenance and investment planning decisions.

The data gathered provides structured information that can be integrated with analytical and management models.

It has been announced recently that the company has seen the highest percentage fall in water loss when compared with other water companies in Bulgaria, it now intends to develop the system further in order to cover all DMAs with water consumption of over 1000 cubic meters per day.
