Underground Stormwater Detention Solutions
Save Installation Time. Reduce Cost. Maximize Usable Space.
If you need to meet stormwater retention requirements without sacrificing valuable surface area, underground detention is often the most efficient solution.
We provide turnkey delivery of underground detention systems, from plan review and system sizing to installation and maintenance.
Why Developers and Engineers Choose Underground Detention
When land value is high and footprint is tight, above-ground retention isn’t always practical.
Underground systems help you:
Preserve buildable space for parking, amenities, and revenue-generating use
Reduce installation delays with streamlined sizing and coordinated execution
Lower total system cost through value engineering and right-sized design
Meet municipal and DOT requirements with compliant documentation

Solutions We Deliver
We provide underground detention systems tailored to site constraints and load requirements:
Modular Storage Systems
High-capacity modular storage tanks designed to maximize underground detention volume while fitting within tight site footprints.
Arch Chamber Systems
Lightweight chamber systems that provide efficient stormwater storage and are commonly used beneath parking areas, roadways, and landscaped spaces.
Soil Cell Systems
Integrated soil cell structures that support healthy tree growth while providing underground stormwater storage and infiltration capacity.
Integrated Stormwater Strategies
Underground detention systems can also be combined with other stormwater control measures, such as permeable pavement or bioretention, to optimize storage performance and site functionality.
Case Study Snapshot
McDonald’s
Hanson, KY
The Challenge
The development required a stormwater management solution that could meet detention requirements without reducing valuable parking and drive-through space on a compact commercial site.
The Solution
Greenrise supported the project with an underground detention strategy designed to provide the required stormwater storage while preserving the site's functionality. The underground system allowed stormwater to be stored below grade, keeping the surface area available for customer parking and circulation.
The Outcome
The project successfully met local stormwater management requirements while maintaining the layout needed for the restaurant’s operations. By placing detention storage underground, the development maximized usable site space without compromising regulatory compliance.
