Brazil accounts for around eighteen percent of the global water supply, yet the distribution of water is highly uneven. Improper sewage facilities are one of the main challenges facing Brazil today, as up to seventy percent of untreated sewage is disposed of directly into rivers. With this being recognized, Brazil directed its attention towards wastewater treatment and aimed for new wastewater treatment systems to be fully functional in time for the Olympics.

The Deodoro wastewater treatment plant

The plant is located in Deodoro, Rio De Janeiro, where a number of Olympic events were held during the games in August.

The first task was to take care of sewage treatment for neighbourhoods surrounding the Olympic events. The new plant has up to ten times the capacity of the original plant and treats an average of 64,800m3 of water each day. Subsequently, a significant decline in the flow of domestic sewage to the rivers in Guanabara Bay and the West Zone where the sailing events took place is to be expected.

Under this scheme eleven pumping stations, two hundred kilometers of new sewage networks and 25,000 household connections are planned to be a part of the first investment phase. The new wastewater treatment installation in Deodoro is the first in America to use Dutch Nereda technology.

In the long run, the plant will have the capacity to adapt to the region’s population growth leaving an impacting legacy on the 2016 Rio Olympic Games. Five more plants are set to follow throughout Brazil.

The Deodoro wastewater treatment plant in Rio De Janeiro is now fully functioning and was completed in time for the Olympics.

Targets

On the ‘Improved Water Source’ data sheet, Brazil’s clean water source level has risen over the past few years (rising from ninety seven in 2011 to ninety eight in 2012 and staying at a consistent level), however they are not quite there yet . With the help of the new wastewater cleaning system, Brazil is aiming for their clean water levels to rise to one hundred percent within the coming years.

The plant forms the base for wider improvements under the Foz Aguas 5 scheme that aims to mobilise R$640 Million for sanitation works in order to improve the local population’s health and environment.
