Foz Aguas 5 opens wastewater treatment plant in Rio de Janeiro, Brazil

The Deodoro wastewater treatment plant owned and operated by Foz Aguas 5 in Rio de Janeiro, Brazil, has opened in time for the Olympics, which will be held from 5 to 21 August this year.

The plant is integrated with Royal HaskoningDHV’s sustainable Nereda technology and treats the wastewater of 480,000 people.

Foz Águas 5 shareholder 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."

The plant forms the core of improvements under the Foz Águas 5 scheme that is set to mobilise R$640m (€164m) for sanitation works.

As part of the investment in first phase, 200km of new sewage networks, 11 pumping stations and 25 thousand household connections are planned under the scheme.

Located in Deodoro, the initial task of the plant will be in the sewage treatment for the neighbourhoods surrounding the sports complex and will treat 64,800m³/day.

In future, the new wastewater treatment plant can accommodate the region’s projected population growth.

Dutch Consul-General in Rio de Janeiro Arjen Uijterlinde said: "The new water treatment installation in Deodoro – the first in the Americas with Dutch Nereda technology – will contribute to better living conditions of many thousands of inhabitants in these poorer parts of Rio and will help to make the Guanabara Bay cleaner.

"With only a couple of weeks left to go until the Olympics, the city of Rio is already celebrating this legacy and I am confident that other water sanitation projects will follow this lead."
