We deliver smart, integrated water solutions that help clients achieve their sustainability goals across the entire water cycle. From design and build to operations and maintenance, our expertise spans water treatment, wastewater treatment, and water recovery.

We rank among the global top 10 players in biological wastewater technologies (ranking by Global Water Intelligence), with proprietary anaerobic and aerobic solutions such as BIOTIM® Anaerobic and LUCAS® Cyclic Activated Sludge. To complete our solutions portfolio, we also offer short-term rental solutions for liquid–solid separation through Krofta DAF Rental. With over 175 years of combined operational experience, we operate critical water infrastructure worldwide, including more than 20 municipal O&M projects in Morocco alone.

Our digital platform, SMARTLAB®, empowers clients to reduce operational costs and risks through predictive insights, advanced analytics, and digital twin modelling. To make sustainable infrastructure more accessible, the Waterleau International Financing Vehicle (WIFV) enables public-private partnerships and off-balance-sheet investment solutions.

The commitment of the Waterleau Group goes beyond the protection of water alone. Through Socrematic—our specialist in air pollution abatement, flue gas, and off-gas treatment—we extend our impact to air quality and industrial emissions control.
