Águas de Nova Fribugo

In January 2009, Águas de Nova Friburgo started providing sanitation services in Nova Friburgo, in the mountainous region of the state of Rio de Janeiro.

At the time, the wastewater was not treated and the water supply system had a flow rate of 580 liters per second.

Today, 95% of the population has access to treated water, and 90% of the wastewater is treated.

Fifteen Wastewater Treatment Plants (WWTP) treat about 50 million liters per day. Over the past six years, three WTPs have been replaced and two other WTPs are expected to be replaced in the next two years. The four Wastewater Treatment Plants (WWTPs) set up in the city are responsible for treating 40 million liters of sewage per day.

Águas de Nova Friburgo was the first sanitation company in the state of Rio de Janeiro to use Moving Bed Biofilm Reactors (MBBR). This system allows 95% of the organic matter to be removed during the wastewater treatment process in a relatively small space, without any noise, and it does not give off any unpleasant odors compared to other technologies.

Over 40 years of concession, the company plans to invest more than BRL 125 million in the city, and BRL 94 million of these were pledged in the first seven years.

Águas de Nova Friburgo plans to build two other WWTPs — the Ponte da Saudade WWTP and the Cônego WWTP, totaling six plants.

In 2009, the utility Águas de Nova Friburgo initiated constructions of wastewater collection and treatment facilities and committed to transform the city into a national reference in sanitation. It built about 10 km of water and wastewater pipes in the city, renovated the Water Treatment Plants (WTPs), upgraded the pumping stations and set up an Operational Control Center an online telemetry system. The clients also got a new customer service center at Rua Moisés Amélio, in the city center.


The first Wastewater Treatment Plant, the Olaria WWTP, was started on June 13, 2010 to treat 30% of the sewage collected in the city. Aware of its responsibility towards the socioeconomic, cultural and environmental development of the city, Águas de Nova Friburgo implemented the program “Amigos da Água,” or “Friends of Water,” with the support of the Department of Education. The first edition of the competition awarded the five best sentences by students of public schools on the theme “The rivers of Nova Friburgo.”


Four hundred employees from the Group worked around the clock and reestablished, in just 11 days, the water supply disrupted by the January 11th climatic disaster that affected the Rio Grande de Cima WTP and the water mains.

In June, the sports event “Corrida Águas de Nova Friburgo pelo Meio Ambiente” (Águas de Nova Friburgo Race for the Environment) was launched to raise awareness about the protection of the environment.

In December, the Campo do Coelho WWTP was started.  The unit treats 38 million liters of wastewater per day and benefits 2,000 local residents. The Operations Control Center was fully automated.


The utility launched the Touring Customer Service project in a van truck especially designed to take the same services available in the customer service center to the most populous suburbs and districts — Olaria, Conselheiro Paulino and Lumiar.  The Centro WWTP, the third in the city, was started on July 13th in Vale do Sol, in Duas Pedras. The unit treats 35% of all the wastewater collected in the city. Together, the three WWTPs were built to treat 65% of the wastewater collected in the city, which is above the national average that is below 40%.

In December, a Contingency Plan and Manual was created to address risk situations in the rainy season.


This year, several improvements were made, the structures of flow and pressure control of the São Geraldo and Duas Pedras reservoirs were built, and the simultaneous interconnections of the areas supplied by the former Rio Grande de Cima system were completed. A 1.5-million-liter reservoir was set up in São Geraldo. In Catarcione, over 3,500 meters of sewage pipelines coming out of 800 households were replaced.

The utility also built water and sewage systems and an 80,000-liter reservoir in Parque das Flores, Conselheiro Paulino, to serve 330 affordable homes built for those who lost their houses to the 2011 floods.


The suburb Morros dos Maias received 2.2 km of water pipelines connected to 200 units; 2,200 households in the fenced community for low-income families Terra Nova, in Conselheiro Paulino, were benefited from 2.7 km of water pipelines. In October, the utility built a water distribution system to serve 120 households in Loteamento Vale Radiante, in Rui Sanglard.

On December 4th, the Conselheiro Paulino WWTP, with monthly treatment capacity of 336 million liters of sewage, was put into operation.  With this unit, Nova Friburgo was able to treat more than 90% of sewage. Next to the WWTP, Viveiro-Escola Águas de Nova Friburgo, a greenhouse with seedlings of plants occurring in the Atlantic Forest, was set up to receive schoolchildren.

The utility laid another 7.6 km of pipelines to take treated water to more than 200 properties in the Fazenda da Laje community. Other constructions include 2.6 km of extended water pipelines in the suburb of Vargem Grande, with 158 units; 5.2-km extension of the Caledônia/Cascatinha Untreated Water Main for 2,000 units; interconnection of the Rio Grande de Cima System, in Bela Vista, to a 1.6-km pipeline extension for 700 housing units.

In the district of Conselheiro Paulino and in the suburb of Catarcione, 1.8 km of sewer pipes were laid. At the Olaria WWTP, the sludge aeration, settling and dewatering system was upgraded.


On February 27th, Águas de Nova Friburgo completed the upgrade of the Santa Margarida WTP, in Lumiar, benefiting 3,000 inhabitants of the 7th District. The Bengalas River crossing bridge was built in Conselheiro Paulino. The bridge is a 28-meter long 7-ton steel structure that was designed to run the pipeline that will carry all the sewage from the left bank of the river to the Conselheiro Paulino WWTP.

On the 198th anniversary of Nova Friburgo, the utility installed a new lighting system in the Praça da Matriz fountain. The Touring Customer Service van goes to the districts of Amparo and Campo do Coelho.


In April, Águas de Nova Friburgo built two other pumping stations and expanded the volume of sewage treated at the Conselheiro Paulino WWTP. Altogether, 11 units were built to support the WWTP operations. By the end of 2018, another seven pumping stations will be built. On June 29, the Tapera WTP, in São Pedro da Serra, was upgraded and started, benefiting 2,272 local residents. Also, in 2017, the Rio Grande de Cima WTP dam was structurally recovered to improve the catchment flow, especially in the dry season, and to make sure the system’s supply would keep running.

The water supply system in Nova Friburgo is made up of fifteen treatment plants. The main one is the Rio Grande de Cima plant, with stable productivity even during the dry season, as the water is taken from Grande River, which maintains a constant level throughout the year.

The Grande River is about 200-km long, from its spring in São Lourenço, in the third district of Nova Friburgo, to the city of São Fidélis, to the north of Rio de Janeiro, where it flows into one of the most important rivers in the country: Paraíba do Sul.

The area around ??the spring has intense agricultural activity, with little environmental preservation. However, the plant’s infrastructure ensures 100% potable water free of pesticides.

Taken together, the 15 Water Treatment Plants (WTPs) treat about 50 million liters per day.
