UrbanPond Concrete Stormwater Detention

UrbanPond is a modular precast concrete underground storage system that mimics the function of ponds and open detention basins. 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.

Modules are available in 8’ x 8’ feet square or 8’ x 16’ rectangular options, giving designers more versatility to accommodate dense development, urban infill or larger high-volume projects. The modular design can be placed under roadways, parking lots and landscape areas in various shapes, sizes, and depths. The system’s internal offset leg configuration provides channel-less water distribution for stormwater entering and exiting the system, and the robust precast form allows it to be buried.

UrbanPond Features and Benefits

UrbanPond Modules and Sizing

• Modules are available in 8’ x 8’ feet square or 8’ x 16’ rectangular options, giving designers more versatility to accommodate dense development, urban infill or larger high-volume projects. 
• Modules are available with inside heights ranging from 3 feet to 7 feet, in 6-inch increments.
• Modules can be stacked to increase the height and storage capacity of the system. Using a stacked configuration also eliminates the need for a base slab. 
• Stacked modules are available up to 14 feet. 

 UrbanPond Applications

• Detention/Retention
• Infiltration Galleries
• Flood Control
• Treatment Train Design Options

 UrbanPond Installation

• UrbanPond modules can easily fit onto a flatbed truck, and the size maximizes the space on each truckload.
• As many as 3 individual pieces can be delivered on a single truckload to reduce shipping costs and minimize crane requirements during installation. 

UrbanPond Maintenance

• 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.
• Maintenance support - Contech has created a network of Certified Maintenance Providers to provide UrbanPond maintenance at the lowest possible cost.
