The twin challenges of urbanization and climate change are taking their toll in the form of increasing water scarcity in cities around the world. More people are moving to urban areas – already half the world’s population (55%) lives in cities and the United Nations estimates that number will drop to two-thirds (68%) within just a few decades. expected to increase to At the same time, we are already seeing large swaths of the planet affected by drought, with coastlines eroded and lives lost, due to climate change. By 2022, more than 2.3 billion people will face water stress and about 160 million children will be exposed to severe and prolonged drought.
However, although more than 70% of the planet is covered in water, only 3% of it is drinkable, and a significant portion of these freshwater resources are trapped in glaciers and ice caps. To make matters worse, water demand is projected to increase by 30% by 2050, and the United Nations predicts global water shortages of up to 40% by 2030.
In response, more and more cities are imposing water restrictions to tackle the problem. Santiago and Los Angeles are the two most recent. Governments from the Netherlands to Brazil have developed policy frameworks to regulate water production and management.
But ensuring access to water, a fundamental right for all and part of the United Nations Sustainable Development Goals, requires real-time interventions to help avoid the ever-increasing challenge of water scarcity. Requires onsite management. To that end, municipalities around the world are turning to digital technologies such as data analytics, artificial intelligence (AI), machine learning and the Industrial Internet of Things (IIoT) to support their water security needs. . These smart city solutions generate valuable predictive business insights and improve operational resilience to help authorities understand water needs, protect existing water sources and minimize leaks. and help ensure access to clean water for all.
How Naples manages its water system remotely
Digital technologies are already supporting water and wastewater management as supply and distribution challenges increase while hybrid workplaces become the norm. Gori will centralize water services in 74 Italian municipalities in and around Naples, including Salerno, Vesuvius and Capri, taking over from a patchwork of local providers. But coordinating his 207 million cubic meters of water to more than 1.5 million people over a network of 4,000 km (2,485 miles) as one entity made him difficult to manage at scale. was becoming. His 2,240 km (1391 miles) sewage network spanning 13 treatment plants complicates matters.
Gori’s SCADA team turned to digital technology solutions to solve critical operational challenges and reduce energy consumption in the process. The smart city solution implemented provided operators with single window access from both fixed and mobile stations.
Since implementing the system, Gori’s operations have become both more efficient and sustainable. For example, at Mercato’s Palazzo factory, a remote monitoring and control system has reduced his energy consumption by 45%, leading to savings of around €80,000 per month.
How the City of Salem Predicts and Assures Water Quality
The effects of climate change are complicating water management for utilities around the world, as events such as drought and changes in precipitation patterns are altering patterns of water availability. The city of Salem, Oregon faces a different kind of water quality problem. Rising temperatures have caused the lakes and rivers that supply the city with drinking water to flourish with dangerous blue-green algae. Many of these algae produce toxic cyanotoxins that pose significant challenges to water utilities, including serious safety risks and costly interference with treatment processes. One such four-day event in 2018 led to a month-long recommendation for drinking water, and ultimately the declaration of a state of emergency.
The city turned to our data hub to ensure it was never stunned by such horrors again. A scalable cloud data management platform brings together live data points such as water depth, weather information, water turbidity, satellite imagery and lab samples into a single web-based interface. City officials share this unified information in real time with engineers, ecologists, mathematicians and other analysts.
The program puts previously unreachable data sources within reach of authorities, allowing them to perform predictive analytics to predict the need for water treatment a week in advance of algal blooms and toxic hazards. . This is enough time for operators to take corrective action, such as replacing pumps and filters, or diverting water flow, to ensure that Salem residents have clean, safe drinking water at all times.
How Puerto Rico Can Increase Asset Resilience and Efficiency
The Caribbean territory of Puerto Rico lacks a source of fresh, clean water. However, with over three million residents and an equal number of annual visitors, the demand for water continues to grow. The system that serves them consists of over 16,100 km (10,000 miles) of water mains and aqueducts, and 3218 km (2,000 miles) of sewage lines between 1,500 sites serving his five regions of the island. grew to The island’s diverse and remote terrain means that improved visibility and reduced travel are important.
Puerto Rico’s Water and Sewerage Authority, already one of the world’s most advanced utilities, recently transitioned to a fully automated system with an integrated suite of digital solutions to increase water production, according to the EPA. compliance, increased efficiency, and cost.
We have eliminated as much manual work as possible to proactively manage every aspect of the water and wastewater system. Real-time diagnostics enable operators to monitor the quality of water and wastewater treatment processes, troubleshoot problems, and make timely changes to help prevent non-compliance. Specific outcomes include clean EPA-compliant water, fewer shutdowns, and improved customer satisfaction. Production increased from he 12 million gallons (45 million liters) to he 20-30 million gallons (75-113 liters), saving an estimated $15 million over his seven years.
Smart water solutions improve access to water
Due to the increasing incidence, severity and complexity of water crises, human efforts alone cannot solve the water challenges facing the world’s cities today. The use of digital water technology is transforming water and wastewater management in urban areas around the world. By adopting smart water management, municipalities and utilities can improve resource efficiency, optimize supply, maintain water quality and anticipate maintenance needs while avoiding costly disruptions. I can. In the process, we can improve affordable access to water for all. Appropriately implemented, technology can help mitigate the water crisis.
