Stormwater Detention under Parking Lot

    • Application: Stormwater Detention
    • Location: Wynco Distribution Center, Virginia, USA
    • Details: Stormwater Detention Tank under parking lot
    • Completion: August 2003

After expanding the building, space was tight in this distribution facility’s dock area. Backing large trucks in and out was hard enough, but a large storm water detention ditch on the outer edge of the lot added grave consequences to the slightest wrong turn. Any solution to handle the storm water and enlarge the lot would not only need to stand up to the heavy truck loads, but work within the constraints of an inflexible outlet elevation.

Using the Atlantis Flo-Tank® tank system to store 4,000 cf of stormwater below the parking lot in the same footprint as the ditch added 15′ to the lot. The Atlantis Flo-Tank® tank systems ability to stand up to H20 loads was critical to its selection, and a double tank was used to meet the requirements of the outlet invert.

The Atlantis Flo-Tank® tank mosules not only fit into the project parameters, but it fit in the budget, too. Freight costs were minimized by shipping the units flat and constructing them on-site. By using the tank’s 95% void surface area to infiltrate water, the three acre parking lot drains quickly with no expensive inlet structures.
