Sem Timeline

On April 17, 2015, Águas de Pará de Minas started supplying water and providing wastewater treatment services in the city of Pará de Minas (state of Minas Gerais).

So far, the company has three water treatment plants, including a small one. Taken together, they treat more than 20 million liters per day. Besides, there is a wastewater treatment plant that can handle 15 million liters per day.

The company’s first major project is the construction of the Paraopeba Supply System, whose purpose is to catch water from the Paraopeba River and solve the city’s water supply problems. For the water to get to the treatment plant, in May 2015, a 28-kilometer water main started being built underneath streets and roads before it gets to the Water Treatment Plant in the Nossa Senhora das Graças suburb.

The first stage of the Paraopeba Water Supply System, completed on October 6th, takes 120 liters of water per second to the WTP. Final completion of the Paraopeba Water Supply System is scheduled for the first half of 2016. By then, it will catch 200 liters of water per second.

During the 35-year concession term, Águas de Pará de Minas will invest about BRL 230 million, of which BRL 90 million will be invested right in the first years. A storage capacity increase of 5 million liters of treated water is also planned.

On April 17, 2015, Águas de Pará de Minas started supplying water and providing wastewater treatment services in the city of Pará de Minas (state of Minas Gerais). Straight away, on May 6th, the company started building the Paraopeba Water Supply System to take water from the Paraopeba River, in the Córrego do Barro district, to the Water Treatment Plant located in the Nossa Senhora das Graças suburb. The first stage of the project was completed on October 6th, only five months since it was started, thanks to the hard work of all the teams that did a good quality and speedy job. A 28-km water main was built with initial capacity to pump about 120 liters/second. Thanks to this early capital injection, the local population, which had to sustain so many water shortages, were then to enjoy large amounts of water coming off their taps.


The second year of concession witnessed the completion and expansion of the Paraopeba Water Supply System, renovations and adjustments to the Water Treatment Plant, the Wastewater Treatment Plant and the Customer Service Center. In the Paraopeba System, the three pumping units were completed: catchment facility, Trindade Booster and Costas Booster. The WWTP, located in the União suburb, started to operate with modern efficiency boosting systems, with equipment that neutralizes bad smelling gases and a power generator to make sure the operations are not compromised in a power outage. The Customer Service Center, located at Rua Maestro Espíndola, 270, Nossa Senhora das Graças, was expanded and had an air-conditioning system installed. The place has become accessible for people with disabilities, who can now have easy access to the facility. The WTP was renovated and streamlined. The whole operation is strictly audited, all treatment stages were adjusted and the Plant automation is progressing smoothly to make sure the population is well looked after by complying with the quality parameters demanded by the Brazilian Ministry of Health.


Upgrades to the Operational Control Center and automation of the Paraopeba Water Supply System were major achievements in 2017. As the automation progressed, the control center started to get real-time information from about 50 units at various points around the city and districts, including boosters, water production systems from deep wells, reservoirs, and even the Paraopeba River System. Besides, the company built the power system all along where the 28-kilometer water main runs, providing a safer and more reliable supply system to the population. For two years, the company spared no efforts to operate the entire Paraopeba system, the three pumping units entirely operated by generators, which consumed high volumes of diesel on a monthly basis. The União WWTP received the PTRAT, an equipment that is being installed to boost the efficiency levels in solid, sand and grease removal at the entrance of the plant. The Caetano Preto, Córrego das Pedras, Matinha and Torneiros WWTP underwent major renovations and adjustments. At the WTP, we started the online monitoring of the quality of both untreated and treated water. Quality control was already active and rigorous, but now it relies on cutting edge technologies that will support the chemists in the whole process of auditing the water quality, from the catchment basins to the households. To further improve the services, the company streamlined the Customer Service Center facilities and completely refurbished the unit, which fully meets the accessibility requirements for disabled people, including a restroom especially designed for them.

The utility company Águas de Pará de Minas provides the local population with water treatment, following the highest quality standards.
