How Smart Cities Leverage Wastewater Management for Sustainable Urban Growth

Smart cities are evolving at a rapid pace with the rise of urbanization. IoT technology is being widely used to collect all the relevant data from the cities. It is used for processing smart outcomes and improving people's living standards to a much higher level. With different cities accepting the technology, there are many ways in which IoT is used to transform city development. The most general form of using IoT to upgrade a smart city is to use electronic devices like sensors and gateways to collect detailed information. This is further used to get better results and predict different patterns of how an individual is utilizing the resources in the city.

Resources like water and energy are most commonly used in urban areas. The lavish usage of these resources is gradually leading to their depletion, which can result in a catastrophic event in the future. Therefore, conserving such natural resources is the prime concern of introducing technology to monitor the consumption patterns of every individual. This provides the proper insights and creates a virtual reality that could be a part of our future. To mitigate such challenges, IoT-powered different solutions are used to develop a smart city with proper management and providing an adequate amount of resources for better survival.

One of the smartest ways of re-using water is to process wastewater and make it fit for consumption. Hence, smart cities are employing wastewater management tactics to improve water utilization per individual.

Smart Wastewater Management

As per the report by the World Health Organization, the majority of the people reside in urban areas, and this population is expected to rise by 70% in future.

One of the most crucial pieces of smart city infrastructure is its water system. With the growing city population, inevitably, water consumption will also increase. Cities are introduced to the term 'smart water' that points to water and fully-fledged wastewater infrastructure, which ensure effective management of this precious resource. Smart wastewater management is developed to collect meaningful data about the flow, pressure, and distribution within a city. The gathered data is effective enough to obtain actionable insights for better decision-making.

Moreover, fresh water is on the verge of getting scarce day-by-day. The current wastewater systems such as Supervisory Control and Data Acquisition Systems (SCADA) have several limitations like difficult installation, higher costs, and maintenance issues. These limitations reduce the capabilities of the SCADA and other such management systems to fulfill the increasing demands of fresh water.

How Smart Wastewater Management Systems Promote Water Conservation?

IoT technology is a smart concept to enable reliable communication between wastewater management systems and administrators. It brings a beneficial combination of utility and cost-savings, which improves overall productivity. Moreover, it is an effective way to identify potential areas of water wastage and take actions accordingly to minimize the same.

• The IoT sensors are capable to detect combined sewage overflows. You can set threshold values with the help of smart solutions and get a real-time notification as soon as the sewage water overflows. This helps you preserve combined sewage overflows and reduces water wastage at a significant level.

• IoT-powered solutions can detect the presence of any chemical and their ratio in water during the treatment. This promotes better water quality and predicts how much processing is required to clean the water.

• Using IoT technology is an effective approach to detect the presence of leakage pipes. Smart solutions are equipped with advanced analytics and algorithms to analyze the data captured through distribution pipes. It helps the authorities to know the patterns and provides insights about the pipe leakages.

In the rainy season, rainwater is the major reason for the overflowing of the sewages. This results in poor management of wastewater and affects lots of human lives. IoT technology thus helps in monitoring the real-time status of the inflow of water with the help of sensors. Also, it is a smart way to identify the chemicals present in the water or pipelines. Moreover, it sends instant alerts on the remotely connected dashboard regarding the chemical traces and ensures quick release of chemicals before it shows any severe effects.

IoT-enabled sensors and communication gateways are innovative concepts that help water utilities to improve wastewater management and its treatment across the facilities. A smart city is thus developed by concerning the issues regarding natural resource consumption, which enables healthier living. The data-driven approach is a vast concept that can improve the accuracy of insights and enhance the industrial functionalities to a greater extent. It also promotes better industrial management and improves the ways of water consumption. With the help of actionable insights, the citizens could be more aware of the benefits of using the technologies and know the areas where they are consuming more water. Thus, there is a need for smart cities to employ smart wastewater management practices and plan a better infrastructure for the implementation of IoT-powered systems.
