The Largest Water Reservoir In Latin America Will Store 900 Million Liters In São Paulo, With Open-Air Reservoir, High-Flow Pumps, And Integrated Pipelines To Protect Whole Neighborhoods Against Floods With Monitored Operation And Controlled Drainage.
The construction of the largest water reservoir in Latin America represents a technical turning point in the macro-drainage of the capital of São Paulo. The reservoir was designed to hold peak rainfall, reduce overflow, and gradually return water, creating an extra layer of security for strategic roads and densely urbanized areas.
Located in a critical flooding area, the project combines capacity of 900 thousand cubic meters, integration with channelized streams, and large pump houses. The logic is simple and efficient for extreme events: store quickly and release slowly, with telemetry, operational control, and maintenance routines. The largest water reservoir in Latin America is born to transform what was once chaos into hydraulic predictability.
Where It Is And Why The Location Is Strategic
Implemented on the border of São Paulo with São Caetano do Sul, in the Vila Livieiro area, the reservoir is located near the Anchieta Highway and the confluence of the Ribeirão dos Meninos with the Ribeirão dos Couros.

Every pineapple you eat is actually up to 200 different fruits fused into one: discover the fascinating process in which each flower opens for just one day and produces the pieces that form the whole fruit over the course of 3 weeks.
The choice of site responds to decades of flooding that affected neighborhoods such as Sacomã, Ipiranga, and the center of São Caetano, as well as metropolitan logistical routes.
The position reduces water transport times to the detention basin and facilitates connection with the existing network.
The largest water reservoir in Latin America functions as a hydraulic node of first response for heavy rains in a highly impermeablized basin, with a direct effect on mobility and public safety.
Capacity, Hydraulics, And Operation In Rainy Conditions
With 900 thousand cubic meters of usable volume and an approximate characteristic depth of 13 meters, the reservoir receives contributions from new and existing pipelines, including about 700 meters of rectification and conduction of the Jaboticabal Stream.
At the entrance, energy dissipators and low-velocity zones favor the settling of solids and protect the pumps.
The pump house operates with six motor pump sets of approximately 850 liters per second each, resulting in a total flow close to 5.1 cubic meters per second.
Under nominal conditions, the emptying of 900 thousand cubic meters can occur in the order of two days, always adjusted to the level of the receiving body and the operational guidelines to avoid downstream overloads.
The largest water reservoir in Latin America prioritizes hydraulic safety through staged activation and transient control.
Civil Engineering, Geotechnics, And Reservoir Integrity
The construction arrangement is of a open-air reservoir with stepped slopes, waterproofing barriers, and bottom protections compatible with a constant moisture regime.
The project provides for grating, trash racks, and settling units to minimize obstructions, vortices, and abrasion on pumps from suspended particles.
The execution involves large-scale earth movement, localized containment, and site drainage, all while managing sediments to prevent sedimentation of the network.
The durability of the largest water reservoir in Latin America depends on periodic inspections, cleaning of grates, removing sludge, restoring toe drains, and reviewing coating surfaces.
Scale And Comparison With Other Macro-Drainage Works
The volume of 900 million liters, equivalent to more than 360 Olympic swimming pools, places the project among the largest hydraulic interventions ever carried out in the Metropolitan Region of São Paulo.
It surpasses traditional reservoirs such as Pacaembu and Paço in capacity and basin reach.
In international terms, the solution is comparable to large urban detention works due to its storage scale and operational integration, although with a distinct type of multimodal drainage tunnels.
The largest water reservoir in Latin America adopts an open and high-capacity configuration suitable for the local topographic and urban context.
Timeline, Investment, And Institutional Coordination
The history of the basin shows recurrence of floods over decades, with social and economic losses.
Macro-drainage studies were consolidated, and the project advanced to bidding and civil works with an estimated investment of 573 million Brazilian reais, including expropriations and associated works.
The future operation requires coordination between the state and municipalities, integration with control centers, rainfall telemetry protocols, and level protocols, and decision-making routines for opening and closing gates and modulating pumping.
The largest water reservoir in Latin America only delivers its potential with governance, maintenance, and continuous operation.
Limits, Benefits, And What Changes In Practice
Detention reservoirs do not eliminate floods on their own.
They reduce flow peaks and buy time for the main network, with real gains when there is integration with micro-drainage, maintenance of catch basins, and urban waste management.
The performance depends on rainfall, operation, and the capacity of the receiving body.
In practice, the population should notice fewer overflow points, greater road fluidity on critical days, and less material damage.
For commerce and metropolitan logistics, this means productivity and predictability.
The largest water reservoir in Latin America also tends to appreciate the surrounding urban area by reducing recurring risk and attracting investments.
With record capacity, robust engineering, and operation modulated by telemetry, the largest water reservoir in Latin America was designed to transform intense rain events into manageable scenarios.
The project enhances safety, reduces losses, and inaugurates a level of hydraulic resilience for one of the most sensitive areas of the metropolis.
And you? Do you believe that this model of large reservoirs should expand to other critical basins in the city or do you see more efficient alternatives to reduce floods in your neighborhood? Share your experience and what you would change first in the urban drainage of your region in the comments.
Acho que a água captada pelo piscinão deveria abastecer as residências próximas. Para isto seria preciso tratar a água.
Deveriam fazer uma coisa bem melhor. Criar um rio subterrâneo até a serra do mar. E despeichar no mar pequeno. Captando aguas em áreas de alagamento direto para o Rio subterrâneo.
rio subterrâneo?? explica como isso seria, sem occorer erosão, deslizamento de terra e desgaste do solo, isso com orçamento limitado e 50km até a serra do mar, “gênio”
Sensacional atitude da parceria governo / município , parabéns aos gestores ! 👏👏☺️
