The Deodoro wastewater treatment plant in Rio de Janeiro, Brazil, has opened in time for the 2016 Olympic Games, which are scheduled to be held in August.


Brazil’s Foz Aguas 5 owns and operates the plant, which has the capacityto treat wastewater of 480,000 people.

The facility features Royal HaskoningDHV’s sustainable Nereda technology.

One of the first tasks of the facility is to treat water from the neighbourhoods, the sports complex. It will also treat sewage from expanding neighbourhood in the region.

The plant has a new sewage network of about 200km with 11 pumping stations. In the first phase, the plant will have about 25,000 household connections.

Royal HaskoningDHV water products and innovation quality director João Almeida said: "The Deodoro Nereda plant is not only a landmark project for its impressive capacity, but also for the actual contribution to the whole region of Rio de Janeiro.

"With an additional plant in Jardim Novo, Rio Claro under construction and several more under design in São Paulo and Recife we are looking forward to bringing Nereda technology to other regions in Brazil."

The original wastewater treatment in the region had a capacity to treat about 64,800 m3/day. The new plant, according to Royal Haskoning has 10 times the capacity of the original plant.

With such high capacity, Royal Haskoning hopes that sewage from the region will not let into neighbouring rivers in West Zone and Guanabara Bay, where sailing events will be held.

Foz Águas 5 shareholder and engineering manager Odebrecht Ambiental, Giancarlo Ronconi, said: "We are true believers regarding Nereda technology – as matter of fact we understand that we are developing in conjunction with Royal HaskoningDHV, a breakthrough solution for large WWTP with high process efficiency and excellent cost benefit ratio..
