Ecological public toilet flushing validated by the Competitiveness Cluster of the Water Sector.

Hydréos is a network aimed at bringing together research laboratories, communities and companies in the grand Est in order to promote collaborative innovation among stakeholders in the water sector . The Hydréos network brings together internationally recognized skills and expertise. Hydréos has itself been labeled “pole of competitiveness” by the State.

This competitiveness cluster has been supporting innovative projects in several areas of strategic activity since 2010, including wastewater treatment, which is a crucial issue of the 21st century.


Hydréos emphasizes the fact that the management of wastewater in the form of large centralized networks has limits that must be compensated for by local solutions , based on more autonomous systems .

The WeCo solution is perfectly autonomous and very localized . WeCo public sanitary facilities have neither an ecological impact on the environment nor a negative economic impact on the colossal water treatment budgets of the city where they are installed.

WeCo’s public flush toilets have an extremely positive and perfectly sustainable environmental record.

The Hydréos label should allow this innovative technology and full of the future, to develop rapidly.
