Structure built by Sanepar in Tatuquara has a capacity of 10 million liters, expands regional storage to 25 million liters, and is expected to start operation in July after tests on the new distribution network
The Paraná Sanitation Company, Sanepar, completed the construction of the largest treated water reservoir in Latin America using double steel technology in Curitiba. The structure is located in the Tatuquara neighborhood and is expected to start operation in July, after the completion of tests on the new distribution network installed in the region.
With a capacity to store 10 million liters of treated water, the reservoir was designed to directly reinforce the supply to about 130,000 residents. The structure will serve neighborhoods in the southern region of the capital, such as Tatuquara, Umbará, Cidade Industrial de Curitiba, Sítio Cercado, and Pinheirinho.
Additionally, the project enhances the water security of Curitiba and the Metropolitan Region. The new equipment also increases the operational flexibility of the Integrated Water Supply System of Curitiba, known as Saic, allowing better distribution among served areas.

Reservoir in Tatuquara expands stored water capacity to 25 million liters
The new reservoir has a diameter of 54 meters and a height of 4.4 meters. The structure was built next to an existing concrete reservoir, with a capacity to store another 15 million liters of treated water.
Thus, the total storage capacity in the region increases from 15 million to 25 million liters. The increase is considered strategic by Sanepar, especially in light of the population growth in Curitiba and nearby municipalities in the Metropolitan Region.
According to Sanepar’s Investment Director, Leura Lucia Conte de Oliveira, the expansion follows the growing demand for supply. The director highlighted that the company continues to make new investments to serve Curitiba and the Metropolitan Region.
In addition to reinforcing the capital’s supply, the structure can assist in providing water to neighboring cities. Among them is Fazenda Rio Grande, a municipality that can also benefit from the system’s greater flexibility.
Double steel technology reduces construction time and improves durability
The main innovation of the project lies in the technology applied in the construction. The reservoir was made with two layers of steel, one galvanized on the outside and the other stainless steel on the inside.
According to Sanepar, this model ensures greater durability, reduces the need for maintenance, and helps preserve the quality of treated water. The solution also allowed for speeding up the execution of the work compared to traditional structures.
The reservoir was completed in approximately 12 months. This timeframe represents a reduction of about 50% compared to the time normally required to build a conventional reinforced concrete reservoir.
The pieces used were custom-made and assembled directly at the construction site. Thus, the execution also reduced waste generation and minimized waste during the construction process.
Sanepar’s investment reached R$ 40 million
Sanepar’s total investment reached R$ 40 million. Of this amount, R$ 15 million was allocated to the construction of the treated water reservoir in Tatuquara.
Another R$ 25 million was applied to the implementation of 27 kilometers of new pipelines and the installation of two new pumps at the region’s pumping station. Thus, the project was not limited to storage but also advanced in distribution.
According to Sanepar’s CEO, Wilson Bley, the investments aim to prepare the system for urban growth and the challenges posed by climate change. The goal, according to him, is to ensure treated water and health for the population of Paraná.
New network promises to improve pressure, distribution, and response in emergencies
The new distribution network has been integrated into the existing system. This measure will allow for the creation of smaller supply sectors, which facilitates water pressure control and improves daily operations.
Additionally, the division into smaller areas tends to reduce impacts during any maintenance. In practice, targeted interventions can affect fewer residents and facilitate the company’s technical response.
Sanepar’s expectation is that the new setup will increase the reliability of supply in the southern region of Curitiba. The structure is also expected to strengthen the system’s response capacity during periods of higher demand or in emergency situations.
With the reservoir, new pipelines, and installed pumps, the region now has a more robust structure for storing and distributing treated water. The delivery marks an important stage in the water planning of Curitiba and the Metropolitan Region.
