Haskoning is pleased to announce our exclusive license agreement with METAWATER Co., Ltd for the Nereda® technology in Japan.

METAWATER is a leading company in the water and environmental sector, dedicated to developing, renewing, and maintaining infrastructure for a sustainable future. METAWATER provides comprehensive services and solutions for water, sewage and waste treatment projects.

METAWATER's strong local presence and understanding of the market will facilitate the adoption and growth of Nereda® technology. The adoption of the technology aligns with METAWATER’s mission to reducing environmental impact and promoting energy-efficient solutions across Japan.

“METAWATER and Haskoning have many synergies including the culture of innovation driven by the desire to contribute socially and sustainably”, commented João Almeida, Director of Water Technology Products at Haskoning. “We also have an existing relationship through years of working with their subsidiary and look forward to a similarly successful relationship and rollout in the Japanese market.”

 “We are very pleased to have entered into a license agreement with Haskoning for the Nereda® technology,” said Tatsuo Kato, Executive Officer and Executive General Manager of the Environmental Engineering Division at METAWATER. “In Japan, there is a growing demand for technologies that support labor-saving operations, energy efficiency, and decarbonization. At the same time, the need is increasing for both the replacement and retrofit of existing wastewater treatment plants. With a strong track record of successful implementation in North America—through our subsidiary AASI (Aqua-Aerobic Systems, Inc.)—and in Europe, we believe that Nereda® will not only contribute to solving these societal challenges but also serve as a key driver in the growth of METAWATER’s business.”  

METAWATER is the parent company of Aqua-Aerobic Systems, Inc., the Nereda technology licensee for the United States and Canada. Since 2016, Aqua-Aerobic Systems has successfully implemented the technology with 9 operational sites and another 40 in construction or submittals stage.
