India's economy is booming. As a result of this, the people of this predominantly rural emerging economy are increasingly moving to the economically important conurbations. While in 2016 about one third of India's 1.31 billion people lived in cities, the urban population will grow by another 400 million by 2050, according to forecasts by the United Nations. However, the expansion of urban infrastructure in the country with the second largest population in the world is already barely keeping up with the rapid pace of urbanization.
Furthermore, India's metropolises are also struggling in particular with the lack of an adequate water supply and the disposal of wastewater. In many places the supply of drinking water is limited to a few hours a day, and many districts are not yet connected to the water supply network. Similarly, many urban areas lack sewage systems and sewage treatment plants. Wastewater is therefore discharged untreated into rivers and lakes, which simultaneously provide drinking water for the municipal water supply system.
With intelligent concepts for the water innovation hub
"Smart Water Future India", a project coordinated by the Fraunhofer Institute for Interfacial Engineering and Biotechnology (IGB) and funded by the German Federal Ministry for the Environment, Nature Conservation, Building and Nuclear Safety since the beginning of October, aims to develop intelligent solutions for making rapidly developing cities more livable, efficient and environmentally friendly. A concept for the sustainable water management of an intelligently networked city is to be developed using the example of the southern Indian metropolis of Coimbatore, a traffic junction in the state of Tamil Nadu.
Specific recommendations for action should show urban decision-makers how they can sustainably improve the water supply and wastewater disposal situation. Ultimately, the environment also benefits from these measures – through the reduced consumption of resources and the relief of groundwater and surface waters.
At the same time, the project can help German companies in the water sector to gain access to the huge Indian market for water and wastewater management. Although the study being implemented without any preconceived notions as to the results and is solely based on demand in India, the aim of the project is to pave the way for long-term partnerships between German companies and the Indian water industry – also beyond the end of the project. Above all, small and medium-sized companies in the German water sector can therefore benefit from the network, which is to establish a "water innovation hub" in Coimbatore.
