Underground Modular Storage Systems
PRIMELOS manufactures concrete-free stormwater attenuation systems for the collection, temporary storage, flow regulation, and infiltration of surface runoff. The modular structure enables the construction of underground reservoirs of virtually any capacity without the use of reinforced concrete structures or heavy construction equipment. PRIMELOS engineers provide complete system configuration based on hydraulic calculations, soil conditions, traffic loads, and operational requirements.
Systems of Concrete-Free Stormwater Accumulation
The system is designed for the construction of underground attenuation and flow-control reservoirs installed upstream of stormwater pumping stations, infiltration fields, and drainage tunnel systems.
Thanks to its modular structure, the solution can be seamlessly integrated into municipal drainage infrastructure, industrial facilities, residential developments, and standalone commercial projects.

Applications of Concrete-Free Stormwater Accumulation Systems
Modular attenuation units allow the construction of underground reservoirs with the required capacity and geometry, reducing peak loads on stormwater drainage networks and ensuring controlled management of surface runoff.
Storage reservoir
Temporary storage of peak stormwater volumes before treatment, discharge, or pumping. The reservoir accumulates excess runoff during rainfall events and gradually releases it into the drainage network.
Flow-Control Reservoirs
Reduction of hydraulic load on stormwater pumping stations, surface runoff treatment systems, and municipal drainage infrastructure.
Water Infiltration
Gradual discharge of treated rainwater into the ground under suitable hydrogeological conditions.
Drainage Tunnels
Collection, redistribution, and controlled conveyance of surface runoff on roads, parking areas, and engineering sites.
Integration into Complex Stormwater Systems
The system is compatible with grit separators, local treatment facilities, pumping stations, inspection chambers, and flow-control equipment.
Installation of the System
The reservoir is assembled from modular elements in layers, after which the structure is wrapped with a covering material depending on its application: geotextile for infiltration systems or geomembrane for sealed stormwater storage.
Site Preparation
Excavation works are carried out, followed by leveling and preparation of the foundation base in accordance with project loads and site conditions.
Module Assembly
The modules are installed with staggered joints using a brick-pattern layout, creating a stable high-capacity underground structure.
Wrapping & Pipe Connection
The assembled structure is wrapped with geotextile or geomembrane, after which inlet and outlet pipelines are connected.
Backfilling
Layer-by-layer backfilling is performed in compliance with compaction requirements to ensure long-term structural stability and reliable operation.
Configurations
System Configurations
Each configuration is selected based on the calculated stormwater volume, reservoir purpose, soil conditions, groundwater level, traffic loads, and maintenance requirements.
| System Type | Purpose | Wrapping Material | Typical Applications |
|---|---|---|---|
| Storage Reservoir | Temporary storage of stormwater runoff | Geomembrane + protective geotextile | Shopping centers, warehouses, industrial facilities, residential developments |
| Flow Control Reservoir | Reduction of peak discharge before pumping stations or municipal sewer networks | Geomembrane | Urban infrastructure, parking areas, logistics centers |
| Infiltration Reservoir | Gradual infiltration of water into the ground | Filter geotextile | Green zones, private properties, commercial facilities |
| Drainage Tunnel | Collection and redistribution of surface water | Geotextile | Roadways, driveways, landscaping, utility areas |
