In January 2008, the concessionaire Águas das Agulhas Negras took over the sanitation services in Resende. This year the company gave priority, among other things, to the treatment of sewage in the city, which until then was only 6% of what was collected. Work began immediately after the beginning of the concession, with the renovation and improvement of STP Alegria. The opening of the station, fully modernized, happened in July 2008 and since then, 45% of the sewage started to be collected in the municipality and treated in the unit.
Months later it was time to put in place another sewage treatment station until then abandoned: Isaac Polit, whose processing capacity is 3 liters per second. With two openings, STP Alegria and STP Isaac Polit, the municipality peaked at 54% of treated sewage, making it the city of Vale do Paraíba Fluminense with higher treatment volume.
Among the 2008 achievements stand out even the deployment of the MSM System (Management Services Module) for the maintenance of water and sewage systems, since the first day of activity, reading the water meter with simultaneous printing of bills, deployment of the Operational Control Center, working 24 hours a day, deployment of laboratory of water quality and sewage, the opening of the new store service in the downtown area, and the implementation of Call Water 115 and Ombudsman Office.
This year, water treatment station Engenheiro Passos was expanded, increasing its treatment capacity to 30 liters per second and transforming it into a complete treatment plant.
The concessionaire drafted the Main Station Water Treatment, with the capacity to treat 400 liters per second, built in the grounds of the Alegria Treatment Plant in the neighborhood Itapuca in two modules, each with a treatment capacity of 200 liters per second. The project was prepared in accordance with all technical and environmental standards for the station to be one of the most modern in the State of Rio de Janeiro.
The clean-up of Lago Mirante das Agulhas, the Lagoa do Bairro Morada da Barra and clean up the swamp that separates the neighborhoods Elite and Vila Santa Isabel were three major environmental achievements of Águas das Agulhas Negras in 2009.
Moreover, we highlight the development of the Municipal Sanitation Plan (Water and Sewage), the continuity of the renovation works of all water treatment plants and the expansion and replacement of water and sewage mains and pumping recovery. Investment in Sewage Treatment Plant Alegria also continued. Also in 2009 it was installed a centrifuge to dehydrate sludge.
This measure helps to reduce the volume of sludge generated during sewage treatment, facilitating their transport to the final destination. After sludge being treated it is sent to a composting company and is later reused in agriculture.
Águas das Agulhas Negras arrived in late 2010 counting large numbers, the percentage is 90% approval of the concessionaire services by Resendense population, which have been proven in the last trimester in a survey conducted by the Institute Gerp, either by the volume of work performed during the year, as the reforms and expansion of Monet Sewage Treatment Plants and water from Fazenda da Barra, plus dozens of kilometers of deployment and replacement of networks, both water like sewage in various neighborhoods.
In 2011 investments in sewage increased. Águas das Agulhas Negras signed an agreement with the company Servatis passing to treat the sewage from neighborhoods Parque Embaixador, Campo Belo and Fazenda da Barra II in Sewage Treatment Plant from the own agrochemical.
With this, Resende became the city that treats the largest volume of sewage from the southern state of Rio, reaching 60%. The goal of the concessionaire was to further increase this percentage, anticipating goals of the edital and predicting for 2012 the start of works of a sewage treatment plant in the neighborhood São Caetano.
The year 2012 amounted to significant achievements. To better accommodate the customers and welcome them in a warm and comfortable space, the Concessionaire reformed the service shop, located in the city center, now with the introduction of the new Group brand Águas do Brazil. Continued the replacement project to install water and sewage networks in the various districts of the city, providing improvements in the system of water distribution and sewage collection. In addition, the program implemented loss control, where a team conducted surveys at night looking for hidden leaks with a device called a geophone.
In June, the concessionaire completed the construction of the boardwalk and handed to the municipality completely urbanized. Also inaugurated the largest and most modern water treatment plant, WTP Alegria. Considered the main treatment plant of the city, the unit is designed to treat up to 400 liters of water per second, allowing self-sufficiency in treated water the coming decades.
Parallel to the work of WTS Alegria, Águas das Agulhas Negras deployed a treated water pipeline over 3,600 meters long. The pipe will enable water produced at the station to be transported to the reservoir of 3 million liters, which is being implemented in Jardim Jalisco.
Ending the actions in 2012, the concessionaire started the project for deployment São Caetano Sewage Treatment Plant. The unit should be launched until February next year.etano. A unidade deverá ser inaugurada até fevereiro do próximo ano.
