Sherwin Williams wanted to add a store in the growing Forest Lake area along busy Broadway Avenue but couldn’t find a site to suit their exact needs. They ended up building on a very tight site next to some existing buildings and proposed future development.

In order to gain the necessary parking spaces the Engineer chose to use Contech’s Aluminized CSP Underground Detention System along with a Vortechs unit to treat the water before entering the cities storm sewer system, which eventually flows into pristine Forest Lake.

Technical Description:

  • Aluminized Steel Pipe
  • 36” Diameter, 14 gage, 443 LF of pipe
  • Vortechs Model 2000
