The Challenge
Águas do Porto (AdP), a major water company in Portugal, is responsible for managing the entire urban water cycle of the city of Porto. This includes water supply, wastewater drainage and treatment, stormwater drainage, surface waters, and coastal water quality. The company serves approximately 500,000 people, delivering an average of 49,450 cubic meters of water daily and collecting the same amount for treatment. The system includes extensive kilometers of wastewater sewers, stormwater drainage pipes, streams, and ocean coast. The hydraulic infrastructure and water resources in Porto had become dense and complex due to a growing number of tourists, with over 1.5 million people visiting Porto in 2017 alone. To improve water system management and system resilience, AdP needed to create models for various systems that incorporate weather forecasts, water supply, sewer flow, and storm drainage rates. These models would consume large amounts of data from sensors throughout the system, including sensors measuring customer water use and billing. AdP gathered all water system data within dozens of siloed software systems. However, finding information and gaining actionable insights became difficult as the volume of data increased. To manage the growing number of systems and data sources and provide reliable service to its customers, AdP decided that establishing an integrated management system was paramount for handling the entire urban water cycle effectively.
About The Customer
Águas do Porto (AdP) is a major water company in Portugal, responsible for managing the entire urban water cycle of the city of Porto. This includes water supply, wastewater drainage and treatment, stormwater drainage, surface waters, and coastal water quality. AdP serves approximately 500,000 people, delivering an average of 49,450 cubic meters of water daily and collecting the same amount for treatment. The system includes 558 kilometers of wastewater sewers, 660 kilometers of stormwater drainage pipes, 66 kilometers of streams, and 3.4 kilometers of ocean coast, half of which are used as beaches. The company is one of the largest water companies in Portugal with more than 157,000 customers. The hydraulic infrastructure and water resources in Porto had become dense and complex, due in part to a growing number of tourists, with over 1.5 million people visiting Porto in 2017 alone.
The Solution
AdP planned to create a unified smart water management platform called H2PORTO, which it would use to promote a culture of innovation and efficiently harness its existing resources and data, rather than build new systems. To build and manage H2PORTO, AdP awarded the contract to a consortium that included Bentley Systems, a leading provider of infrastructure software solutions. The team used Bentley software— including OpenFlows WaterGEMS, OpenFlows SewerGEMS, and OpenFlows FLOOD—for its seamless plug-in capabilities to integrate data from all AdP sources and produce a digital twin of the city’s water supply, wastewater, stormwater, and coastal water systems. The digital twin enables H2PORTO to track current conditions and forecast future conditions. H2PORTO integrates data from 22 types of sources, including billing, meters, sensors, operations, weather stations, and control systems. By combining the data into a federated digital twin, AdP receives the near real-time status of each part of the water system in a single view. Now, AdP can model and forecast the entire water system at once, rather than separately modeling each part. Moreover, H2PORTO displays the information in user-friendly dashboards and incorporates automatic alerts and warnings for when potential problems arise. The platform provides AdP with the ability to visualize the water system and get greater insight into it.
Operational Impact
  • With H2PORTO fully operational and integrated into all parts of the water system, the city of Porto has seen significant improvements to its water supply. The volume of non-revenue water dropped by 3.5%, and the rate of replacing traditional water meters with smart water meters has nearly doubled. Integration of real-time data and producing information available to teams in the field produced operational gains of 23%. Since H2PORTO is remotely accessible via a tablet, technicians now use the platform to register asset details and changes without having to file paperwork between offices. By unifying the data produced by formerly siloed systems, AdP has improved the accuracy of the data produced from sensor readings to nearly 99%. With more accurate data, AdP has improved overall decision-making and reports its employee and customer satisfaction have increased.
Quantitative Benefit
  • Remote access to H2PORTO allows technicians to update digital twin information while in the field, resulting in operation gains of 23%.
  • Forecasts, alerts, and what-if scenario modeling lowered water supply interruptions by 22.9%.
  • By unifying the data, AdP has improved the accuracy of the data from IoT devices to nearly 99%.
