In a nutshell
What are Nature-based Solutions for Water Treatment?
Nature-based solutions for water treatment utilize treatment processes found in nature. These technologies are cost-effective, can be built with locally-available materials, and simultaneously provide environmental, social and economic benefits, while helping build urban resilience.
What is Multisource
MULTISOURCE will demonstrate Nature-based Solutions for urban water treatment, storage, and reuse. The technical pilots will treat wide range of urban waters. Decision support tools will be co-designed together with local, national, and international stakeholders.
Increasing urbanization poses a range of challenges worldwide, including water scarcity, water insecurity, human health issues, and loss of ecosystem services such as clean air, water, and soil. To satisfy their water demand, many cities rely on extensive supply infrastructure to transfer water over long distances. This infrastructure approach limits the resilience of cities against the effects of climate change because the infrastructure cannot be easily or cost-effectively adapted, expanded, or repaired.
In light of the increasing pressure on water resources worldwide, the integration of decentralized approaches into existing centralized infrastructure is essential for achieving sustainable, efficient, and affordable water resource management, increased water reuse, and establishing a circular water economy.
