Oldcastle Precast Provides Heavy Duty, Compact Stormwater Detention System For Nashville Fire Station

Untitled

To detain stormwater runoff at the Metro Fire Station # 21, the Metropolitan Government of Nashville and Davidson County elected to remove an above ground detention pond and construct an underground stormwater detention system to gain back valuable land for parking during the recent replacement of the facility.

The first design of the new stormwater detention system specified 36” corrugated metal pipe but concerns regarding fire truck traffic loading on the system  resulted in a change to  36” reinforced concrete pipe. This in turn could not be used as it would not fit in the required footprint under the facility’s driveway.

In the final design, Oldcastle Precast’s Storm Capture stormwater management system was chosen and subsequently constructed under the entrance road, since it reduced the detention system width and overall footprint by over 40%, and easily fit under the fire station roadway.

Oldcastle Precast manufactured and supplied the Storm Capture detention system at their Lebanon, TN plant.  The final system contained (16) Storm Capture modules at 3’ tall, installed on top of (16) base slabs, for a total of 3,700 cubic feet of detention storage. In addition, (5) catch basins/storm structures, 15” & 18” reinforced concrete pipe, and (3) sanitary manholes were provided for the project. The installation of the entire drainage system was completed in (1) one day.

The detention system was a portion of the overall project to construct a new 21,000 square foot Fire Station for Nashville’s Fire Department. Fire Station #21 is expected to achieve LEED Silver certification.

Littlejohn Engineering designed the stormwater system and Summit Constructors performed the installation for Messer Construction, the general contractor on Fire Station # 21.
