The Water Treatment Alliance [NL: Water Zuiveringen Alliantie | WZA] is a sustainable permanent partnership consisting of Mobilis, Croonwolter&dros, RWB Water, TAUW and Sweco. As an independent system integrator, we focus on the entire life cycle of a water treatment plant. We are specialized in the design and construction of:
1. Sewage treatment plants for the treatment of sewage water.
2. Additional wastewater treatment plants for the removal of micropollutants from sewage water (e.g. drug residues, crop protection products)
3. Potable water treatment plants (Potable Water Production Companies) for clean potable water.
