UrbanPond® is a technological breakthrough in underground stormwater management. Its unique square tessellation assembly provides superior strength and material efficiency over traditional rectangular modules. It has high void percentages to maximize stormwater volume, and its robust precast form allows systems to be buried deeper without the need for specialized backfill, increased wall thicknesses, or extra rebar reinforcement.


  • Lighter Weight, Easier To Install
  • Designed To Meet H-20 Loading Requirements
  • Can Be Installed Deeper Without the Need to Increase Wall Thickness or Add Additional Rebar
  • Square Tessellation Provides Superior Strength and Load Capacity
  • Higher Void Percentages & Increased Material Efficiency for Best In Class Cost Per Cubic Foot Storage
  • A Linkup Slab Allows Elimination of Some Modules, Further Decreasing Cost and Installation Time
  • Every Module Drains Down Fully
  • Does not require rock at back-fill in most applications

Learn More About UrbanPond

Our local stormwater experts come to you!

UrbanPond is a modular precast concrete underground storage system that mimics the function of ponds and open detention basins. Each module is only 8 feet square which minimizes pick weight and crane size requirements. The modular design can be placed under roadways, parking lots and landscape areas in various shapes, sizes, and depths.

Maintenance & Installation

UrbanPond is designed to be easily accessed and maintained from finished surface via multiple access ports. Using a standard vacuum truck, each access point is conveniently located, as ports are strategically placed throughout the assembly.

Modules can be modified to act as clear wells or pretreatment chambers for capturing trash, debris, and sediment. This consolidates maintenance requirements to a select few modules. Standard manholes, hinged manholes, and other access hatches are available.

Each Single UrbanPond module is 8 ft. wide by 8 ft. long (O.D.) and easily fits onto a flatbed truck. This size maximizes the space on each truck load. A 12 foot Double UrbanPond module (two pieces) weighs only 20,000 lbs. total, or only 10,000 lbs.
As many as 4 individual pieces can be delivered on a single truckload to reduce shipping costs and minimize crane requirements during install. Most units can be installed using a simple backhoe due to low weights.
