UNDERGROUND STORMWATER MANAGEMENT
GETSCO helps contractors, engineers, developers, municipalities, and owners evaluate underground detention systems that manage runoff without surrendering valuable surface area.
Use Space Twice
Manage water below parking, landscapes, roads, and usable open areas
Control Peak Runoff
Temporarily store stormwater for managed release or infiltration
Fit the Site
Evaluate footprint, depth, loading, layout, and outlet requirements
Project Guidance
Preferred Rainstore3 support plus alternative system evaluation
Surface detention ponds can consume valuable acreage, interrupt site circulation, and limit how a property can be developed or used.
Underground detention relocates storage below grade, allowing the surface above to remain available for parking, roadways, recreation, landscaping, pedestrian areas, or other project functions.
The system temporarily receives stormwater during a rain event and releases it at a controlled rate, infiltrates it into the surrounding soils, or supports another approved stormwater-management strategy.
GETSCO helps project teams evaluate the storage requirement, available footprint, installation depth, anticipated loading, inlet and outlet configuration, soil conditions, construction sequencing, and long-term access needs before identifying the most appropriate system.
INVISIBLE STRUCTURES RAINSTORE3
Rainstore3 is GETSCO’s primary underground detention and retention solution. The modular system uses preassembled, stackable units to create subsurface storage beneath parking areas, roads, landscapes, recreation areas, and other usable surfaces.
Its high internal void space provides substantial water-storage capacity without requiring the units to be filled with gravel. Modules can be arranged horizontally and vertically to fit a broad range of footprints, depths, and storage requirements.
Rainstore3 can be configured for temporary detention and controlled release, infiltration, retention and harvesting, or other project-specific water-management objectives.
Because the units arrive preassembled, installation can move from delivery to placement without the on-site assembly required by many modular systems.
GETSCO can help coordinate product information, preliminary configuration, quantity review, availability, technical documentation, and manufacturer support.
Rainstore3 is designed to provide high-capacity underground storage while preserving flexibility in system layout. Individual units can be stacked and arranged to match the detention volume, excavation geometry, cover requirements, and site constraints.
The system can be installed beneath traffic-bearing or landscaped surfaces when the complete assembly, cover, subgrade, backfill, geosynthetics, and structural design are appropriate for the application.
Rainstore3 should be evaluated as part of a complete stormwater system that includes pretreatment, inlet and outlet structures, conveyance, geotextiles, geogrids where required, liners when applicable, overflow provisions, and access for inspection or maintenance.

Store More Water Within the Available Footprint
Rainstore3 gives project teams the flexibility to shape underground storage around the site rather than forcing the site around a fixed chamber layout.
A successful underground detention installation depends on how water enters, moves through, exits, and is maintained within the complete assembly.
STEP 1
Stormwater is collected through surface drainage structures. Pretreatment may be needed to reduce sediment, trash, and debris entering the storage system.
STEP 2
Water enters the underground system and occupies the available void space during the storm event.
STEP 3
Stored water is released at an approved rate, infiltrated where conditions permit, retained for reuse, or managed through another designed outlet strategy.
No underground detention system should be selected from storage capacity alone.
The configuration must also account for excavation limits, available surface area, burial depth, traffic or structural loading, groundwater, soil conditions, inlet and outlet elevations, release-rate requirements, constructability, product availability, inspection, and long-term maintenance.
Rainstore3 is GETSCO’s preferred solution for many underground detention applications because its modular construction, high void space, and stackable format allow it to adapt to a wide range of project geometries.
When site conditions, specifications, loading requirements, installation constraints, or other project factors make Rainstore3 impractical, GETSCO can evaluate and supply alternative underground detention systems.
The objective is not to force one product into every site. It is to identify a practical system that satisfies the design and can be installed successfully.
PROJECT FLEXIBILITY
A modular detention system can be configured around columns, utilities, pavement limits, landscape areas, and other site constraints that may prevent a single large chamber or conventional surface basin from fitting efficiently.
Rainstore3 has been used for projects ranging from small runoff-control installations to large underground storage basins. GETSCO can help evaluate whether its modular approach aligns with the available footprint and design criteria.
Rainstore3 is our primary underground detention solution, giving customers a clear starting point backed by product knowledge and manufacturer resources.
When Rainstore3 is not feasible, we help evaluate other underground detention options rather than forcing the wrong system into the project.
GETSCO can help coordinate storage modules, geotextiles, geogrids, liners, drainage components, technical documents, and material availability.
START WITH THE SITE
Send GETSCO the detention volume, plans, elevations, loading requirements, and project schedule. We will help evaluate Rainstore3 first and identify an alternative system when the site requires a different approach.
