Detention Tank for Shopping Mall Parking Lot

    • Application: Stormwater Detention
    • Location: Williamsburg Shopping Mall, Virginia, USA
    • Details: Stormwater Detention Tank under parking lot
    • Completion: June 2008

The job was a major shopping center expansion which called for approximately 9628 m³ (340,000 ft³) of underground detention, equivalent to the volume of practically 4 Olympic swimming pools.

Most of that volume was installed to replace an existing pond that was previously on the site. Additional volume beyond what was held in the pond was required due to the additional retail & parking space. The cover materials over the Atlantis Flo-Tank® tank modules was an open-graded stone (not sand).

The project had to be done VERY QUICKLY in order to get the new stores open in time. To meet the schedule we had crews of up to 25 people working long days to assemble and install about 20,000 cubic feet (566.3 CUM) per day. The Atlantis Flo-Tank® tank system was the best option for the project because it minimized the disturbance to the site and to the existing tenants/stores which stayed open throughout construction.
