Cofunded by the European Union

Water4All was present at the IWA Water Reclamation and Reuse 2025. This biennial event is organised by the Water Reuse Specialist Group of the IWA International Water Association.

The biennal gathered around 750 participants from five continents. Link here

Key topics

The key topics of this conference included risk assessment, urban reuse, and potable water reuse, the focus of LNEC’s presentation. In addition to the scientific results on direct potable reuse for building the social trust in water reuse safety, Maria João Rosa (LNEC)  highlighted the Water4All EU partnership objectives and strategy, and the Water-Oriented Living Labs (WOLL) role, as illustrated for the Lisbon WOLL.

Session on "potable water reuse" of the Lisbon WOLL

The session on Tuesday, April 18, 2025, called “Pilot-scale studies of advanced wastewater treatment for direct potable water reuse for beer production”, was a demonstration of the work done on a concrete example, showing its feasibility and explaining the process. 

Focus on the Lisbon Water Smart Living Lab (WOLL)

The Lisbon WOLL innovation actions included a pilot demonstration of water reclamation for artisanal beer production to provide scientific evidence on the safety of direct potable reuse in industry.

It was established in the scope of the B-WaterSmart project (2020-2024) (Link here) with a strong focus on water reuse. It continues after 2024 as a water-oriented living lab (WOLL) of the Water4All “Atlas of EU WOLLs”. Link here

Objectives:

  • To build the society’s trust and acceptance of water reuse
  • To anticipate solutions for mitigating future scenarios of more severe water scarcity

The  Beirolas Water Resource Recovery Facility, in Portugal: The demonstration took place at the Portuguese Beirolas Water Resource Recovery Facility (WRRF). It is one of the biggest in Portugal, designed for 213,510 population equivalent, comprising anaerobic/anoxic/oxic activated sludge treatment and sand filtration, and receiving urban and industrial wastewater (predominantly domestic) from a combined sewer system in Loures and Lisbon municipalities.

Four advanced treatment technologies were pilot-tested

  • ultrafiltration (UF),
  • ozonation (O3),
  • biologically active granular activated carbon (BAC) filtration,
  • reverse osmosis (RO):

Aiming at comparing different RO-based reclamation schemes towards water quality and operational performance, four different treatment schemes were continuously piloted. Once per treatment scheme, it was analysed for trace compounds (microbial and chemical contaminants). They all produced water with an adequate quality to be reused in the beverage industry, complying with the EU and the Portuguese drinking water quality standards.

 

 

Other news

The Water4All Partnership - Water Security for the Planet - is a funding programme for scientific research in freshwater. It aims to tackle water challenges to face climate change, help to achieve the United Nations’ Sustainable Development Goals and boost the EU’s competitiveness and growth.

It is co-funded by the European Union within the frame of the Horizon Europe programme (a key funding programme for research and innovation). The Partnership duration is for seven years from 2022.

The Water4All objective is to enable water security at a large scale and in the long term. Its goal is also to tackle water issues in a holistic frame. 

All forms of life on earth need water. All human activities operate with this resource. Water is part of our everyday life. It is also integrated within urban and countryside landscapes. It is one of the most valuable elements we share with plants and animals.

These simple facts must be kept in mind to understand the Water4All ambition.

This resource is weakened in many places due to climate changes, and human habits. We know that we can improve the way we use water. Everyone has a role to play and especially the scientific research community.

Scientific research is the heart of the Partnership as It is a powerful tool to improve knowledge on preserving, restoring, and managing this essential resource. 

International cooperation is also needed as water has no borders on Earth and runs from one country to another.

Water4All brings together a broad and cohesive group of 90 partners from 33 countries in the European Union and beyond. This consortium gathers partners from the whole water Research, Development and Innovation (RDI) chain.
