Digitalization of water supply infrastructure to optimize the Water-Energy Nexus

Project Description

The water-energy (WE) nexus describes the vital interaction between two essential components for a modern society. Energy needs water for hydropower, cooling and biofuels. Water requires energy for pumping, treatment and purification. This nexus can be optimized through innovative digital solutions, by securing water supply while improving renewable energy production leading to reduced greenhouse gas emissions and embraced carbon neutrality by 2050.

DIWIEN aims to develop an integrated approach for WE nexus in rural and urban areas by creating a digital twin of the water supply system, identifying possible digitalized solutions as smart sensors or energy recovery units with techno-economic analyses in 4 pilot sites. DIWIEN will create new markets by combining energy and water supply sectors within the WE perspective with minimum environmental impact and maximum energy savings by facilitating the digital transition towards green energy production while ensuring the water supply.
