Water is the most essential resource on earth, but rapid population growth and aging water infrastructure systems pose significant challenges for cities to provide water sustainably in the future. In the first part of this session, students learned about urban water systems and explored water footprints from individual homes to whole cities using interactive software. We discussed water consumption and identified the most important ways in which cities can adapt to improve water conservation. In the second part of this session, students investigated water quality throughout the urban water cycle and learned how the use of sensor networks with green infrastructure systems can improve the sustainability of urban water management. We combined field sampling with interactive laboratory modules to evaluate basic water quality parameters and discussed relationships between water quality, water uses, and public health.
