[브라질] 네르다 폐수처리 시설 올림픽 앞서 운영

리우데자네이루에 있는 데오도르(Deodoro) 폐수처리시설이 올림픽게임에 앞서 운영된다.

로얄 헤스코닝DHV(Royal HaskoningDHV)의 네르다 기술(Nereda technology)을 사용하고 포즈 아구아스5(Foz Aguaz 5)가 운영하는 이 시설은 48만 명의 시민이 배출한 폐수를 처리한다. 향후 브라질 전역에 5개 플랜트가 더 들어설 예정이다.

8월 5일부터 21일까지 몇 가지 올림픽 경기가 개최되는 데오도르(Deaodoro)에 위치한 이 플랜트는 경기장 주변 주민들을 위한 폐수처리를 담당하게 되며, 더 나아가 2016년 리우 올림픽 경기 이후 예상되는 지역 인구 증가에 맞춰 처리용량을 장기적으로 늘릴 예정이다.

이번에 신설된 폐수처리시설은 기존 시설의 10배에 달하는 처리용량으로, 하루 6만4천800㎥에 달하는 규모이다. 결과적으로 요트경기가 진행될 서쪽지역과 구아나바라 만(Guanabara Bay)지역에서 나오는 폐수 배출이 눈에 띄게 줄어들 것으로 기대된다.

아구아스5(Foz Aguas 5)가 설계한 이번 플랜트는 여러 기술향상의 핵심을 구현하며, 지역 주민과 환경 복지를 개선하기 위해서 1억6천400만 유로를 들인 하수처리시설이다.

한편, 200㎞에 달하는 신규 폐수시설 네트워크 계획 하에 향후 11곳의 펌프장과 2만5천 명의 주민들을 연결하는 신규 투자사업이 계획되어 있다.

PLANT OPENS IN BRAZIL IN TIME FOR THE OLYMPICS

The Deodoro wastewater treatment plant in Rio the Janeiro is now operational ahead of the Olympic Games.

The plant uses Royal HaskoningDHV’s Nereda technology and is owned and operated by Foz Aguas 5 and treats the wastewater of 480,000 people.

Five more plants will follow across Brazil.

Located in Deodoro, where a number of Olympic events will be held from 5 till 21 August, the plant’s first task will be in the sewage treatment for the neighbourhoods surrounding the sports complex and in the longer term the plant has capacity to accommodate the region’s projected population growth leaving a significant legacy from the Rio 2016 Olympic Games.

The new wastewater treatment plant has 10 times the capacity of the region’s original one and treats 64,800 m3/day. As a result, there is expected to be a significant reduction in the flow of domestic sewage to the rivers in the West Zone and Guanabara Bay where the sailing events will be held.

The plant forms the core of wider improvements under the Foz Aguas 5 scheme that is set to mobilize R$640 Million (€164 Million) for sanitation works to improve the health of the local population and the environment.

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

Giancarlo Ronconi, engineering manager Odebrecht Ambiental, shareholder of Foz Aguas 5 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”.

Arjen Uijterlinde, Dutch Consul-General in Rio de Janeiro 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.”

Joao Almeida, Director Quality, Water Products and Innovation at Royal HaskoningDHV 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 Sao Paulo and Recife we are looking forward to bringing Nereda technology to other regions in Brazil.”
