The transformation of the water meter fleet in Thessaloniki into a digital one is signaled by today’s signing of a framework agreement between EYATH and two consortiums, for the supply, installation and operation of 200,000 “smart” water meters for household use in the company’s area of activity.
With the implementation of this agreement, combined with the installation of 50,000 new high-precision household water meters in Thessaloniki recently, half of EYATH’s water meter fleet will have already been replaced with precision meters. The ultimate goal is to create a transparent, direct and ultimately digitally interconnected relationship between the company and the consumer and, of course, to save resources.
The framework agreement follows an international tender “for the supply, installation, commissioning and operation of domestic water meters in the area of activity of EYATH S.A.”, with the assignation criterion being the most economically advantageous offer. This is an agreement that defines the terms, conditions and price determination mechanism for the individual executive contracts, based on which the above supplies and services will be provided. These include in more detail: supply, installation and commissioning of electronic water meters together with the associated hydraulic connection materials, supply of a stock of new water meters and delivery to the EYATH warehouses, supply and installation upstream of the water meters of telescopic spherical switches, as well as water meter signal repeaters, provision of metering data collection services for the new water meters, through an advanced reading system (Meter Data Collection – MDC), and provision of a water meter data processing and management service (Meter Data Management – MDM).
The duration of the framework agreement is set at five years from its signing, with the possibility of extension for two additional years, while its maximum value is expected to reach up to the amount of €49,565,000 (excluding VAT 24% – for 100,000+100,000 water meters). The selection of water meters to be replaced – without any burden for consumers – will be made based on criteria mainly of age, while factors such as connectivity, the hydraulic design of the distribution networks and water management in the water supply zones will be taken into account.
“Our primary concern is to provide safe, quality water while responsibly managing the water resources of our region. The use of digital technologies to serve our customers is a central axis of our development, while our strategy is based on transparency, accountability and two-way communication with consumers, ensuring that our services meet their needs and the demands of the climate crisis. From that first ‘Smart Water’ research project in 2017 to the pilot test of “smart” meters on the University Campus, the time has now come to digitize the hydrometric fleet of Thessaloniki using the Internet of Things,” points out EYATH CEO Anthimos Amanatidis.
The modernization of water meters and the shift to “smart” measurements is combined with a series of other projects to reorganize the water supply network of the City Planning Department: redefining the main water supply zones of the tanks, creating new zones for the new tanks to be built, installing equipment and monitoring devices for the operation of the facilities. In this way, non-billed water will be further reduced and additional water resources and energy will be saved, since, for example, the pumping stations will consume energy based on their actual needs.
The shift to “smart” metering required preparatory work as early as 2011, with the creation of an automatic water consumption metering system, implementation of the “Smart Water” research project, hydraulic simulation of EYATH aqueducts, division of the network into control sub-zones (District Metering Areas – DMA’s), collaboration with the Aristotle University of Thessaloniki for measurements of water consumption on the University Campus, implementation of the remote management – remote control (SCADA) project for water supply, as well as the signing of a Memorandum of Understanding and Cooperation with HEDNO.
The companies that signed the framework agreement with EYATH are ACHAIKI ORICHALKOURGIA LTD – N. & K. GOLIOPOULOS SA and MESOGEIOS SA – YDATOR SA.
