Contract signing for the implementation titled:
'SUPPLY, INSTALLATION AND COMMISSIONING OF A SYSTEM FOR MONITORING, REMOTE CONTROL, REMOTE MANAGEMENT AND LEAKAGE DETECTION OF THE EXISTING EXTERNAL AND INTERNAL WATER SUPPLY NETWORK OF IERAPETRA'
Programme: Transport Infrastructure, Environment and Sustainable Development
Total Budget: €700,000.00 (VAT excluded)
Funding: Ministry of Environment and Energy
The purpose of the system is to:
- The continuous monitoring and supervision of key operational parameters of the water supply system (flow rate, pressure, etc.)
- The collection and storage of relevant historical data and the execution of control actions for the management of active components of the water supply system.
The subject of the contract includes the following works:
- Detailed design of the offered integrated system
- Procurement and installation of the electronic equipment (Server, Client, printers, display screens, etc.) for the central station (CSE).
- Integration of the old local control stations into the new monitoring system, so that it operates as a unified, integrated system.
- Integration of the existing system into the new monitoring system, ensuring the support for secure data retention functionality.
- Procurement and installation of the (9) local stations (LSE), (8) control stations of the internal network (ISN), as well as one (1) Quality Control Station (QCS) at a regional well, along with the required equipment for these stations.
- Procurement and installation of all the software required for the operation of the system.
- Procurement and installation of all communication equipment, including any necessary repeaters for the smooth and uninterrupted operation of the system, as well as the submission of applications for obtaining approvals from the competent authorities for communication systems or any other services or agencies required.
- Procurement and installation of the instruments mentioned in the study (level meters, flow rate meters, pressure meters, etc.).
- Factory acceptance tests and on the spot, acceptance tests (field tests).
- Work completion tests and delivery of the system.
- Submission of plan, operation and maintenance manuals (certification).
- Staff’s training of the service in functions, system support and maintenance.
- Operation, support, and maintenance of the system during the trial operation period (12 months).
EXPECTED BENEFITS:
The Municipality of Ierapetra, with this procurement, aims for the complete control and supervision of the entire network. Through this control, the immediate benefits that the Municipality of Ierapetra will gain are:
- Monitoring and continuous recording of the cubic meters of water collected in the external aqueduct.
- Monitoring and continuous recording of the cubic meters of water supplied to the city.
- Monitoring and continuous recording of the cubic meters of water distributed to the various sectors (sub-networks) of the internal network.
- From the two above, and in combination with the final charges to consumers of each section, an indirect perception of the leaks in each sector of the internal network. Also, the determination of unbilled water and the ability to evaluate the measurement – under-recording of existing water meters.
- Calculation and recording of the nighttime consumption of the entire network, which results in the immediate identification of potential leaks in each network section.
- Monitoring and recording of the network pressures for the immediate detection of leaks.
- The ability to produce statistical data on consumption over time, resulting in the ability to draw useful conclusions and the potential for forecasting and planning.
- The ability for automatic pressure adjustment, thereby significantly and effectively reducing hidden leaks during hours when there is no demand from consumers.
- Control of the overflow level of the tanks through the control of pumps and wells, resulting in the reduction of water wastage.
- Energy savings from the controlled operation of the pumps.
- Increase in the lifespan of the pumps due to the "smart" operation of the pumps and continuous monitoring of parameters such as flow rate, operating hours, power supply, monitoring of power on the electric motor shaft, etc.
- Continuous recording of consumption (outflows from the tanks and inflows of the sub-networks of the internal network), which provides useful and immediate information for significant leaks.
- Minimization of pump downtime due to issues, and consequently maximization of continuous coverage for the citizens' water supply needs.
- Reduction of response time for addressing any malfunctions that may occur.
The monitoring, recording, and analysis of data, as well as the operations, will be carried out from the computer of the monitoring center (CSE).
