Upgrading Water Management Network in Oinousses and Gavdos islands

Our Group has successfully signed two important projects for the supply and installation of telemetry systems for monitoring water networks on the islands of Oinousses and Gavdos. These projects are aimed at modernizing and upgrading the water management infrastructure on both islands. Through the installation of advanced digital water meters and remote monitoring systems, we seek to significantly reduce water loss, enhance resource efficiency, and ensure a sustainable and high-quality water supply for the local communities. This initiative reflects our commitment to leveraging technology for more efficient and environmentally responsible water management.
The Challenge
Oinousses and Gavdos have long faced distinct challenges due to their remote location and limited freshwater resources. Water scarcity is a critical concern, with the islands often struggling to meet the demands of both residents and seasonal visitors. The existing infrastructure, plagued by inefficiencies and leaks, contributed to substantial water losses. These issues resulted in a high percentage of non-revenue water, which exacerbated the strain on water resources. Furthermore, the islands’ water management systems lacked real-time monitoring capabilities, making it difficult to optimize distribution or respond swiftly to emerging issues. Beyond operational inefficiencies, there was also growing concern about the environmental impact of inefficient water use, particularly as the islands’ ecosystems are highly sensitive to resource overuse.
The Solution
To address these challenges, we will implement a comprehensive upgrade to the water management systems on both islands. The project includes the installation of advanced digital water meters, which enable real-time tracking of water consumption. This ensures not only more accurate billing but also early detection of leaks, helping to curb water loss.
Additionally, we will integrate a telemetry and a central control system that allows for constant monitoring of the water distribution network. This system provides real-time data on water flow, pressure, and consumption, which in turn enables faster responses to any issues and improves operational efficiency. The new system also allows for the optimization of water usage, ensuring that only necessary amounts are used, thus promoting conservation while maintaining service reliability.
The Results
The implementation of this telemetry system will deliver significant benefits for both Oinousses and Gavdos.

• Real-time leak detection and resolution: The system quickly identifies and addresses leaks, significantly reducing water loss.
• Lower non-revenue water: Improved resource management has decreased the percentage of non-revenue water, leading to more efficient usage.
• Enhanced water quality and reliability: The system ensures a steady supply of high-quality drinking water, even during peak demand periods.
• Environmental benefits: Reduced water waste and optimized resource use align with the islands’ sustainability objectives
• Improved network management: Remote monitoring has increased the responsiveness of maintenance teams, minimizing service disruptions and enhancing overall reliability for residents and visitors
