As of the end of April, Qua-vac has officially joined WaterAlliance – the leading network and industry association for the Dutch water and environmental technology sector.
WaterAlliance now connects over 200 organizations and has grown into a powerful platform where government, science, knowledge institutions, and businesses collaborate. The goal? To drive innovation and promote sustainable Dutch water technology, both nationally and internationally.
As a specialist in sustainable, water-saving vacuum systems for the discharge of greywater, blackwater, and condensate, we look forward to sharing knowledge, working together, and contributing to future-proof solutions – for both existing and new buildings and infrastructure.
Our systems are not only smart and efficient, but also respond to major challenges such as housing renovation, water scarcity, and climate change.
Knowledge Day – June 26, 2025: Visit our booth!
On Thursday, June 26, 2025, WaterAlliance and the InfraCampus in the town of Harderwijk will host an inspiring Knowledge Day focused on decentralized sanitation. Expect real-world examples, engaging speakers, and plenty of opportunities to exchange ideas and insights with peers.
Qua-vac will be there!
At our stand, we’ll showcase a fully operational vacuum toilet – a powerful demonstration of water savings in practice. We’ll also present our Vacuflow® vacuum sewer system, which makes smart, sustainable wastewater solutions possible.
We look forward to seeing you there! More info en full details, check this link (in Dutch)
