UrbanPond™
UrbanPond™ is a modular precast concrete underground storage system, that can be placed under roadways, parking lots and landscape areas, in various shapes, sizes and depths, taking-up zero land-space.
The Ocean Protect UrbanPond™ is a trafficable precast concrete below ground storage system for detention and retention purposes, replacing above ground basins. It has a high void ratio to maximise volume, and its robust precast form allows systems to be buried deeper without the need for specialised backfill, increased wall thicknesses, or extra reinforcement.

How UrbanPond Works
As storms occur, generated runoff is collected and diverted via the pit and pipe network to the UrbanPond™ system. Inlets are accommodated around the system, leading to a traditional below ground detention tank. The internal modular design has a leg configuration that provides channel-less water distribution for stormwater flowing throughout the system. Combinations of inlet and outlet structures are incorporated for associated componentry. The system is installed with a grade on the base, stormwater will make its way through the system towards an outlet chamber with orifice controls. Maintenance is simple and, if required, GPT’s and filtration systems can easily be configured to work in conjunction with UrbanPond™.

Configurations and Applications
- Detention / Retention
- Treatment Train Design Options
- Infiltration Solution Options
- Standard module dimensions of 4.88m x 2.44m are combined for simple design versatility and efficiency
- Each segment will provide 11.48m³ of volume per 1m clear internal height
- Sizing and arrangement is easily determined using the Ocean Protect UrbanPond calculator
Maintenance
- Designed to be maintained from the finished surface via a vacuum truck
- Access points can be strategically placed throughout the system to facilitate maintenance
- Modules can be modified to act as clear wells or pretreatment chambers for capturing trash, debris and sediment
- The large void space and option to include access covers in each module, offers the opportunity to satisfy most if not all Council requirements
