Rhodes goes Digital – How Olympios Group transformed the island’s Water Utility
Rhodes is the largest of the Dodecanese islands of Greece and most visited, experiences sharp fluctuations in water consumption throughout the year due to tourism. During summer, demand surges, placing enormous strain on the island’s water infrastructure. To ensure sustainable and reliable water supply, the Municipal Water and Sewerage Company of Rhodes (DEYAR) partnered with Olympios Group to deliver a full-scale digital transformation by implementing a holistic smart water management system that streamlines operations, saves resources, improves transparency, and supports real-time decision-making.
The Challenge
DEYAR was tasked with managing over 90,000 water meters across the island. However, its infrastructure was outdated and heavily reliant on old-generation meters, which created significant limitations:
Lack of real-time monitoring capabilities
Inability to quickly detect leaks or irregular consumption
High operational and maintenance costs
Inefficiencies in data collection and billing
Difficulty responding rapidly during high-demand tourist seasons
These constraints hindered effective network management and left DEYAR unable to meet the modern demands of water resource planning and service delivery.
The Solution
Olympios Group implemented a comprehensive digital solution that brought DEYAR into the digital era. The centerpiece of the project is a fully equipped Central Control Station (CCS), housed within DEYAR’s existing facilities. This system links all subcomponents into one unified platform for complete visibility and control.
Key elements of the solution included:
Smart Water Meters across the network for precise consumption tracking
Real-Time Monitoring of pressure levels, water flow, and meter statuses
Data Collection Software for mobile and central use
Automated Billing and ERP System integrated with meter data and consumer apps
WebGIS for digital mapping of the network
Hydraulic Simulation Tools to model network behavior
Leak Detection Systems to minimize water loss
Citizen Engagement Portals for water quality and service transparency
Energy Efficiency Software for pump station performance
Central Dashboard Interface consolidating all data and tools into a decision-support system
The CCS was built using open-architecture, distributed systems, and features real-time data processing, visual dashboards, incident reporting, and network simulations. It allows daily updates of fault records with detailed descriptions, GPS data, and images, ensuring complete operational awareness.
The Results
Accurate and Reliable Data Smart meters provide high-precision consumption data, enabling instant detection of anomalies like zero or excessive readings and allowing for swift corrective action.
Reduced Costs and Optimized Resources Automation and centralized monitoring have cut down maintenance costs, reduced water losses, and improved workforce efficiency.
Leak Prevention and Proactive Maintenance Hydraulic simulations and leak detection software support early identification of issues, helping to preserve natural water resources and improve system reliability.
Transparency for Citizens Consumers now have access to water quality information and billing through a digital platform, strengthening trust and service accountability.
Energy Savings and Lower CO₂ Emissions Software that optimizes pump station performance contributes to reduced energy consumption and a smaller environmental footprint.
Smarter Operations with Data-Driven Decisions The integrated analytics dashboard gives DEYAR key insights and performance metrics, improving decision-making for resource allocation and infrastructure planning.
The digital transformation of DEYAR by Olympios Group is a milestone in modern water management. It delivers a sustainable, transparent, and technology-driven model that strengthens operational efficiency and service quality. This project sets a clear precedent for water utilities in Greece and internationally, demonstrating that digital infrastructure is essential to meet today’s public service demands.
