What type of tunnels are most suitable for storm drainage works?
Stormwater drainage works require efficient and sustainable solutions for stormwater management and prevention
Drainage works
Eurohinca (Europea de Hincas Teledirigidas, S.A.), Trenchless specialist since 1996 - 14 TBMs and >120 km executed.
We run drainage works and hydraulic crossings with microtunneling (MTBM), HDD y Direct Pipe, integrated with civil work — hydraulic capacity, scour control, and minimal disruption to traffic and services. See references.
Tunnels for drainage works
At Eurohinca, we specialize in the construction of tunnels intended for drainage works, using trenchless excavation techniques that ensure safe and sustainable water management. These systems are essential in projects involving urban sewage systems and in complex civil engineering projects, where the ability to safely manage stormwater and wastewater flows is key to the resilience of cities.

Service Specifications for Drainage Projects
Urban, industrial, and infrastructure drainage projects require precise, durable construction solutions with minimal surface impact. Trenchless technologies allow for the installation of collectors, deep drains, and underground pipelines with geometric control and full hydraulic functionality. This service is defined by the following technical parameters:
• Main applications: Deep drainage systems, relief collectors, pipelines under roads or industrial areas, longitudinal drainage systems on roads, underpasses beneath infrastructure, capacity expansion of existing networks, and connections between drainage wells.
• Construction methods used: Remote-controlled microtunneling for non-accessible sewers, pipe jacking when depth or access requires it, and HDD for specific routes where gentle curves or limited access are required.
• Diameters and materials: Pipes made of concrete, vitrified clay, steel, or HDPE, depending on the required hydraulic capacity, structural strength, and the regulations of the municipality or managing authority. Diameters are determined based on design flow rates and the slope required for gravity flow.
• Soil conditions and water table: Systems compatible with cohesive, mixed, and stabilized granular soils. In areas with high groundwater levels, closed shields (EPB or slurry) are used to maintain face stability and prevent soil loss.
• Slope Control and Hydraulic Capacity: Drainage systems require specific slopes to ensure efficient water flow without pooling or reverse slopes. Laser or gyroscopic guidance ensures strict tolerances for elevation and alignment.
• Lengths and geometry: Short and medium-length sections in urban areas, crossings under roads or industrial platforms, and longer runs in main drainage channels. The pipeline can be laid in a straight line or with gentle curves when the method allows.
• Civil works requirements: Manholes and receiving chambers adapted to the diameter of the drainage system, work platforms, access points, collection areas, and a sludge treatment plant. The project is designed to minimize disruption to traffic and urban activities.
• Integration with existing networks: Connection to existing drainage systems, adherence to manhole elevations, coordination with underground utilities (water, gas, electricity, telecommunications), and protection of sensitive infrastructure.
• Quality Control and Final Inspection: CCTV inspection, leak tests, geometric checks of alignment and slope, recording of excavation parameters, monitoring of earth pressure and excavated volume, and delivery of as-built documentation.

International Experience
Projects around the world
Eurohinca has carried out drainage projects in Europe, Latin America, and Asia, always implementing solutions tailored to the conditions of each site.
These projects ensure the safe drainage of stormwater and wastewater in high-density urban areas.
In fact, international institutions such as the World Bank They emphasize that the implementation of sustainable urban drainage systems is key to reducing the impact of flooding and strengthening cities' resilience to climate change.
Drainage Projects: Rapid Response
What Are Drainage Projects?
The drainage works These are actions aimed at pick up, transport, or evacuate water (such as stormwater or runoff) to control accumulation, prevent damage, and ensure the proper hydraulic functioning of an area or infrastructure. In many cases, these involve networks and intersections that require the design of sections under specific environmental constraints.
When to use
They are used when it is necessary to manage rainwater or runoff in urban, industrial, or infrastructure-related settings, especially if there are traffic restrictions, easements, or interference with utilities. If the drainage system involves passing through existing structures, it may be related to infrastructure crossings o river and watercourse crossings.
Key data
Approximate location and objective (collection, conveyance, relief, evacuation).
Sketch or plan with a preliminary layout and connection points.
Known environmental restrictions (access, occupancy, hours, interference).
Recommended information
Available documentation on the site (existing plans, background information, constraints).
Requirements of the owner/operator or administration (if applicable).
If the project requires the construction of underground sections using trenchless methods, this can provide context microtunnel y pipe ramming.
