TAPPING INTO THE UNTAPPED - The potential of reclaimed and non-potable waters to increase water resilience | Athens (and online), 20 June, 14:00-16:30 EET

20 June 2024 14:00–16:30

Aqua Publica Europea is pleased to invite you to our next public seminar: "Tapping into the Untapped: The potential of reclaimed and non-potable waters to increase water resilience"


Tapping into the Untapped: The potential of reclaimed and non-potable waters to increase water resilience 

The event will take place in person at Stavros Niarchos Foundation Cultural Center (Leof. Andrea Siggrou 364, Kallithea 176 74, Greece) and online.

The increasing impact of climate change on the availability and quality of water resources requires adaptative and agile approaches to increase Europe’s resilience in water management, as pointed out by the European Commission in its recent communication on managing climate risks. Utilising varying qualities of water for different purposes can serve as a viable strategy to alleviate pressure on valuable high-quality freshwater, which should be preserved primarily for drinking purposes. However, transitioning from a system where drinking water is used for all purposes to one that differentiates water quality based on its intended use poses several challenges in terms of governance, technical arrangements, and safety.

Through the insights provided by experts and policymakers, this public seminar aims to explore technological advancements, regulatory developments, and governance frameworks that could facilitate the utilisation of non-potable water for a variety of societal needs.
