Climate change and infrastructure deficiencies in water networks are causing a growing and alarming water scarcity worldwide. In Italy alone, water losses due to infrastructure issues reach significant levels, estimated at 156 liters per day per inhabitant: an amount sufficient to cover the water needs of about 44 million people annually. This means that actual water consumption is double what is truly necessary, precisely due to such leaks.

Currently, over two billion people live in water-stressed areas, and 45% of the world's population, around 3.4 billion people, lacks access to safe sanitation facilities. Independent estimates indicate that by 2030, the world will face a global water shortage of 40%, further complicated by challenges such as COVID-19 and climate change.

Water is vital for life and the prosperity of communities, but water infrastructure often faces challenges and problems that compromise its supply, both in terms of quantity and quality and hygiene. In this scenario, the Internet of Things (IoT) is emerging as a transformative force, presenting innovative solutions for the monitoring, management, and optimization of water resources.

Detection and Prevention of Infrastructure Issues

Water networks often span vast geographic areas, making it challenging to promptly identify any infrastructure problems. IoT enables the implementation of smart sensors along water pipelines capable of detecting anomalies such as leaks, corrosion, or structural failures. Real-time data allows operators to intervene promptly, minimizing downtime and ensuring continuity in water supply. Traditional network surveillance meter by meter is costly, and traditional forecasting is no longer sufficient.

New technologies allow for real-time analysis of data from sensors and vibraphones installed along water networks, capable of capturing any variations in predominant frequencies and indicating the presence of breaks.

Water Quality Monitoring

The qualitative aspect of water is also a crucial concern. IoT offers advanced tools for constant monitoring of key parameters, such as the presence of contaminants or water temperature. In case of deviations from acceptable levels, IoT systems can send immediate alerts, allowing operators to take timely corrective measures. This level of monitoring ensures that the water reaching homes is always safe and compliant with quality standards.

Waste Reduction and Resource Optimization

Efficient water resource management is essential to address challenges related to growing demand and climate variations. Thanks to IoT, it is possible to implement intelligent management systems that optimize water use. Flow sensors and remote control devices allow for identifying and resolving waste, adjusting distribution based on actual demand, and predicting consumption peaks.

New technologies represent a significant breakthrough in the water sector, enabling a more intelligent, efficient, and sustainable global water management: an indispensable ally to collectively overcome one of the most critical challenges of our time.

Cities around the world are facing increasingly complex challenges related to population growth, urbanization and the environment. In response to these challenges, the concept of "Smart City" is gaining increasing relevance, using technology and innovation to improve citizens' quality of life, optimize resources, and promote environmental sustainability. In this article, we will explore in detail how Smart Cities are transforming Europe, analyzing the most innovative applications and focusing on the development of Smart Cities in Italy.

Smart City: Concept and Foundations

A Smart City is a city that integrates advanced technologies, data and connectivity to improve efficiency, safety, sustainability and quality of life for citizens. The foundations of a Smart City include:

Advanced Technological Infrastructure

Smart cities are equipped with a network of sensors, cameras, wireless networks, and high-speed connectivity to collect real-time data. This data fuels decision-making and automation of public services.

Data and Analysis

Data processing is crucial. Smart cities use data analytics to make informed decisions and optimize resources. Data from sensors, cameras, and IoT devices enable more efficient management.

Citizen Participation

Actively involving citizens in decision-making and information sharing is essential to the success of Smart Cities. Citizen participation promotes the sharing of data and feedback to improve public services.

Smart City Applications in Europe

Smart cities in Europe are implementing a wide range of innovative solutions to address urban challenges. Here are some examples of use cases:

Sustainable Mobility

European cities are promoting green public transport, electric vehicles and shared mobility systems to reduce air pollution and improve air quality. Creating efficient transportation networks is a key objective.

Smart Waste Management

IoT sensors in waste collections monitor bin fill levels, optimizing collection routes and reducing costs. This smart waste management improves efficiency and reduces environmental impact.

Smart Public Lighting

Smart street lights adapt to environmental and traffic conditions, saving energy and improving safety. Real-time control of public lights is a key feature.

Smart Buildings

Smart buildings in Europe use automation to optimize energy use, reducing consumption and improving occupant comfort. Building management systems are central to this goal.

Digital Public Services

Smart cities offer online public services, simplifying interactions with municipal government, from booking parking spaces to requesting documents. Digital platforms increase accessibility to services.

Smart Cities in Italy: Innovation at the Service of Cities

Italy is taking significant steps toward the development of Smart Cities. Here are some notable initiatives:

Milan: Shared Mobility

Milan is investing in shared mobility systems, including electric bikes and car sharing, to reduce traffic and improve air quality. The city is aiming for sustainable mobility.

Turin: Intelligent Lighting

Turin has implemented a smart lighting system that adjusts the intensity of lights based on weather and traffic conditions. The city aims to reduce energy consumption.

Florence: Environmental Monitoring

Florence uses IoT sensors to monitor air quality and noise pollution, providing real-time data to citizens. The city promotes environmental awareness.

Bologna: Intelligent Buildings

Bologna is promoting the energy upgrading of public buildings, reducing consumption and CO2 emissions. The city is committed to sustainability.

Rome: Digital Services

Rome offers digital public services, enabling citizens to make online payments, book services and access useful information. Digitization simplifies procedures.

Outlook for the Next Two Decades

Smart cities in Europe have a promising future for the next 20 years. Some of the prospects include:


Smart cities are changing the face of European cities, improving the lives of citizens, promoting sustainability and optimizing efficiency. Italy is following this trend with innovative initiatives in many of its cities. The goal is to create urban environments that are smarter, sustainable and geared toward people's well-being. The evolution of Smart Cities is a growing process, and Europe is playing a key role in this urban transformation. Global urban challenges can be addressed with creativity and technology, improving the quality of life and the environment in which we live. Looking ahead, Smart Cities will continue to thrive and bring positive change to European communities.
