Sewage collector of Ciudad Real Wastewater Treatment Plant (WWTP)

Ciudad Real main sewer

The Ciudad Real Main Sewer Project is a key project in the improvement of the city's sanitation infrastructure. Designed to optimize wastewater management, the collector not only reduces the risk of flooding and overflows, but also contributes to a cleaner and healthier environment for the region's inhabitants.

Thanks to the use of advanced technologies and sustainable methods, this project sets a benchmark in the modernization of urban sewerage systems.

General project details

LocationCiudad Real, Spain.
Main objectiveConstruction of the main sewer to improve the sanitation system.
Geological conditionsHard clay with gravel layers, located below the water table.
Technology used: Earth pressure tunnel boring machine (EPB).

This project responds to the growing need for modern infrastructure in Ciudad Real, ensuring efficient wastewater management.

Technical specifications

Nominal diameter: 2,760 mm.
Method usedExcavation by EPB tunnel boring machine.
Excavated landHard clay with gravel layers below the water table.

EPB technology was essential to maintain the pressure of the excavation face, avoiding surface settlement and ensuring safety throughout the construction process.

Logistics and technical challenges

The project presented significant challenges due to the site conditions and the need to preserve the urban environment. However, thanks to rigorous planning and the use of advanced technology, the teams were able to meet the objectives efficiently.

Project highlights

Soil stabilityThe EPB tunnel boring machine made it possible to excavate without affecting the surface structures.
Minimization of environmental impactSustainable methods were used to reduce disturbance to the environment.
Flow optimizationThe collector increases the capacity of the sewer system, preventing flooding.

Environmental and social impact

The Ciudad Real Main Sewer is a project that transcends technical improvement, having a direct positive impact on the quality of life of the inhabitants.

Environmental protection: Efficient wastewater management contributes to the conservation of local water resources.
Sustainable infrastructureThe modern design of the collector guarantees its durability and capacity to meet future needs.
Public healthImproved sanitation system reduces the risks associated with water contamination.
