nutrient and energy recovery for more
complete autonomy
• Evaluating innovative circular solutions for
their ability to address real world
problems in water scarce cities
Circular solutions for
Water Materials
Key innovations &actions
• Demonstration of a sewer mining modular
unit for wastewater treatment with
Membrane Bioreactor (MBR) and
disinfection
• Enabling novel wastewater reuse options
at the point of demand for urban green
irrigation, urban agriculture and other
non-potable uses (e.g. fire protection)

14. Stakeholder engagement andpublic
acceptance
Re-designing the water system requires active involvement and engagement and
strong levels of collaboration of stakeholders from the whole water value chain
And it requires social acceptance
