Sanitation and Environment.
• 44% of household wastewater is not treated properly, damaging ecosystems and human health. (WHO, 2023) • Only 38% of industrial wastewater is safely treated (based on limited data from 22 countries). (WHO, 2024) • The untapped potential for safe wastewater reuse is around 320 billion m3 per year , with the potential to supply more than 10 times the current global desalination capacity. (UNEP, 2023)
