Odebrecht Ambiental and Royal HaskoningDHV sign wastewater treatment agreement

The Brazilian Water Company Odebrecht Ambiental and engineering consultancy Royal HaskoningDHV have signed a cooperation agreement to implement the innovative wastewater treatment technology Nereda® in Brazil. Odebrecht has planned to build at least twenty Nereda installations in the coming years. The wastewater of millions Brazilians will be treated by Nereda in future. The total contract value is expected to exceed 11,5 million Euro.

For both companies the cooperation agreement represents a leap forward. In Brazil less than 30 percent of all domestic wastewater is treated. Mr Emyr Diniz Costa Junior, Odebrecht Ambiental's Engineering Director said "We believe Nereda can help us to contribute to a better public health by providing people with access to sanitation. The Nereda technology treats wastewater more sustainable. The total cost will be lower than that of conventional technologies we explored". Odebrecht Ambiental starts with three Nereda plants this year. In the next five years at least twenty plants will follow. This includes plants in São Paolo and Rio de Janeiro.

Sustainable sanitation solution for large cities

Royal HaskoningDHV Global Director Water Products and Innovation Mr René Noppeney said "The challenge for many large cities around the world is to find sustainable solutions for sanitation that have a small footprint. Nereda offers that solution." The footprint of a Nereda is up to a factor 4 smaller than that of conventional water purification systems. It consumes 20-30 percent less energy, uses no or minimal chemicals and is more cost-effective. Mr Noppeney continued "We see the Brazilian municipal water and wastewater market as a growth market. It is of great interest for our company that one of the foremost Brazilian water companies has chosen our innovative technology".

Nereda in a nutshell

Nereda is an award-winning, innovative technology that treats wastewater with less energy, chemicals and costs and a smaller footprint than conventional water treatment systems. Nereda treats wastewater with the unique features of so-called aerobic granular biomass: purifying bacteria that create compact granules with superb settling properties. The technology is invented by the Delft University of Technology in the Netherlands and developed in a unique public-private partnership between the University, the Dutch Foundation for Applied Water Research (STOWA), the Dutch Water Boards and Royal HaskoningDHV.

The success of Nereda is its high water treatment capability in combination with significantly lower investment and operational costs, a very small physical footprint (up to a factor 4 smaller) and high energy savings (20-30%). After 20 years of research and development this innovative biological solution is now proving itself as the leap forward in wastewater treatment technology.
