Valdemarín Collector

Valdemarín main sewer

The project of the Valdemarín main collector is a key work for the improvement of the storm drainage and sanitation system in the Hipódromo de la Zarzuela area. The construction of this collector has made it possible to optimize the evacuation of wastewater and rainwater, reducing the risk of flooding in the area.

Thanks to the use of advanced technology and efficient construction methods, it has been possible to minimize the environmental impact and guarantee a long-lasting and sustainable infrastructure.

General project details

Location: Valdemarín, Madrid, Spain
Main objectiveConstruction of the main collector to improve storm drainage and urban sanitation.
Geological conditionsClay and sand.
Technology usedEPB shield segment lining machine DN2760.

This project responds to the growing need for modern infrastructure in the area, ensuring proper stormwater and wastewater management.

Technical specifications

Nominal diameter: 2,760 mm.
Method usedExcavation with EPB shield and prefabricated segments.
Excavated landClay and sand.

The use of the EPB TBM has been fundamental in dealing with ground conditions and ensuring the stability of the tunnel during construction.

Logistics and technical challenges

The development of the collector has required careful planning due to the proximity of critical infrastructure and the nature of the terrain.

Project highlights

Crossing under key infrastructureincluding the Zarzuela Racetrack and main roads.
Optimization of the sanitation systemallowing a greater drainage capacity.
Constant monitoring of the excavation faceThe soil stability is guaranteed and settlement is minimized.

Environmental and social impact

The Valdemarín main sewer not only improves the sanitation infrastructure, but also contributes to the sustainability and quality of life of the inhabitants.
