Physics-Informed Graph Neural Networks for Water Distribution Systems
Water distribution systems (WDS) are an integral part of critical infrastructure which is pivotal to urban development. As 70% of the world's population will likely live in urban environments in 2050, efficient simulation and planning tools for WDS play a crucial role in reaching UN's sustainable developmental goal (SDG) 6 - "Clean water and sanitation for all". In this realm, we propose a novel and efficient machine learning emulator, more precisely, a physics-informed deep learning (DL) model…

Vice President Kamala Harris visited Pittsburgh on Tuesday to announce nearly $6 billion in funding for clean water infrastructure nationwide. 
Kamala Harris joined EPA Administrator Michael Regan to announce $5.8 billion worth of funding for every state in the country.
The vice president said Pennsylvania will get about $200 million. 
Over 2 million Americans live without running water and tens of millions lack access to safe and reliable drinking water and sanitation. …
