UrbanPond® Concrete Stormwater Detention

UrbanPond® is a modular precast concrete underground stormwater storage system that mimics the function of ponds and open detention basins. Modules are available in 8x8 feet square or 8x16 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.

Flood Control

Contech's CON/SPAN® and UrbanPond® precast underground storage systems are designed to maximize storage volume and capture peak storm events to minimize downstream flooding and erosion.

Precast Systems for Stormwater Detention and Infiltration

Contech's CON/SPAN and Urban Pond concrete stormwater detention and infiltration solutions provide the versatility to accommodate any footprint needed. These patented precast structures are engineered to maximize storage and ensure structural integrity.

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 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. 


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 StormFilter maintenance at the lowest possible cost.


UrbanPond® - Concrete Stormwater Detention

UrbanPond is a breakthrough in underground stormwater management. 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.
