Water 4.0 refers to the adoption of interconnected digital systems to drive the transformation of the water sector by adopting advanced sensors, artificial intelligence, automation, cloud computing, big data analytics and digital twins. In this sense, Water 4.0 integrates the physical water infrastructure of the utility and digital systems in order to facilitate monitoring and analytics of all water resource uses. The technology applies to the whole water cycle from water collection, treatment and transportation to consumption and wastewater management and water treatment. Water 4.0 is a response to the growing pressures facing water utilities and industrial water users, such as water scarcity, aged infrastructure, climate change, high energy prices, and increasing water demand. In traditional water management, water utilities relied on manual inspection and monitoring of water resources and systems.

Water 4.0 requires the use of IoT-based sensors and smart water meters which would allow water utilities and operators to continuously monitor water flow, pressure, quality, use, temperature, equipment operations and networks condition. This data can be further processed using cloud computing and AI systems to detect abnormal conditions and potential operational issues. AI is becoming increasingly important in water management as AI-based technologies help in managing leak detection, water demand forecasts, predictive maintenance, pumping optimization, water quality management, waste water treatment, and flood predictions. Digital twins represent another aspect of Water 4.0 as they provide virtual representation of physical infrastructure which allows simulating operating conditions prior to implementing changes into the system.

In addition to individual solutions like sensors and smart meters, water management industry is moving towards the adoption of water management platforms integrating all aspects of water management in a single platform – from metering, water treatment and asset management to network monitoring. Such solution would create business opportunities for technology companies, water engineering firms, water utilities and automated management providers. Nevertheless, not all water management companies are ready to adopt Water 4.0 due to a number of barriers such as high cost of implementation, presence of aged infrastructure, cybersecurity risks, poor data quality, lack of expertise in using digital technologies, and fragmentation of water management systems. Small companies especially have trouble financing large-scale water management initiatives.

Market Dynamics

Driver

Increasing Need to Reduce Water Losses and Improve Infrastructure Efficiency

Water loss continues to pose significant challenges to the water networks managed by municipalities. Pipeline deterioration, connection damage, changes in pressure, illegal usage, and failure to detect leaks on time can lead to considerable amounts of processed water being wasted before it is delivered to end-users. With Water 4.0 technologies, utility companies are continuously informed of the status of the network through such solutions as smart meters, pressure sensors, acoustic sensors, IoT gadgets, and AI-driven analytics. Rather than checking up the whole network at once, the utilities can rely on digital solutions to spot problematic areas of interest requiring attention. This principle may also be employed when dealing with other elements such as pumps, treatment facilities, control valves, water tanks, and other types of infrastructure.

Restrain/Challenge

High Initial Investment and Complexity of Legacy Water Infrastructure

The process of transformation into Water 4.0 involves significant investments in terms of sensors, communication technologies, smart meters, software platform, cloud technologies, cybersecurity, data management, and staff development. While large-scale utilities have an opportunity to plan these investments over several years, this aspect poses additional problems for smaller municipalities because of their financial limitations. Outdated infrastructure remains the other potential problem. Water supply systems were created many years ago; therefore, they do not correspond to the requirements for installing modern IoT sensors, software programs, and databases.

Another important issue concerns the growing relevance of cybersecurity because more devices are connected to the water supply system. Consequently, the number of opportunities for a potential attack increases; thus, the consideration of these aspects should be included in the initial process of design of the new infrastructure of Water 4.0. Quality of data affects the work of AI algorithms. Inadequate or absent information, unreliable sensors, different data format, and low network connectivity cause errors.

Internet of Things (IoT) Segment is Expected to Drive the Global Water 4.0 Market

This particular technology segment is expected to stay relevant since these connected devices collect the necessary data for the purposes of digital water management. Smart sensors are capable of measuring such parameters like water pressure, flow, temperature, quality, condition of the equipment as well as all kinds of operational metrics. All of this data could be delivered via centralized systems that will analyze the collected metrics and derive actionable intelligence out of it. Smart meters are gaining importance as well. Thanks to smart meters, utilities are able to analyze consumption trends, identify any outliers in consumption, increase accuracy of billings and detect the signs of leaks at the household level. Low power technologies allow easier implementation of these connected devices in the water network. With further reduction in the prices for sensors and communication equipment, utilities are expected to monitor all network assets digitally.

Artificial Intelligence & Machine Learning Segment is Growing at a Significant Rate

AI and ML become increasingly relevant because utilities generate greater amounts of data via smart meters, sensors, wastewater treatment facilities, weather systems, and customer management systems. AI can reveal some correlations that might not be obvious when using traditional monitoring. So, for example, the combination of such parameters as flow, pressure, weather and consumption data can be used to make a prediction about the need in a resource or possible leakages.
Furthermore, AI-driven systems can contribute to the improvement of wastewater treatment. So, for instance, such plants will be able to manage aeration, dosing, pumping and other activities in real time, thus optimizing the work process and minimizing energy and chemical utilization. The next developing area for AI is predictive maintenance.

Why North America Led the Water 4.0 Market?

North America will continue to be one of the most important regions for Water 4.0 due to aging infrastructure, developed technology landscape, utility management systems, and investments in advanced water networks.

The United States already has substantial existing infrastructure for water and wastewater management, which needs to be upgraded. There are efforts by utilities to use smart meters, Internet of Things monitoring, artificial intelligence analytics, digital twins, and maintenance solutions.
It should also be taken into consideration that North America has many technology companies, producers of water-equipment, engineering, and software firms. It is possible for the utilities to integrate the digital solutions into the existing infrastructure and not rebuild everything.
