Case Study One
Willowbrook
Three very nicely landscaped storm water retention ponds located behind houses in a Kansas City suburb. The location would not allow access to the ponds with excavating equipment or trucks.
Case Studies - DEWATERING
PROBLEM: Ponds were full of mud
OBJECTIVE: Have clean ponds without any offensive odor
SOLUTION: Small 6" dredge pumped into Envirotubes™ staged in cul-de-sac.
Case Study Two
Archie, Missouri
The city of Archie, Missouri receives its potable water supply from a small river. The river water is pumped into a primary settling pond and flows by gravity into a secondary settling pond. The river water that was filling the ponds contained sediment which reduced the capacity of the ponds, deposited organic material and created algae growth and other organic chemical problems.
PROBLEM: With every storm event, the island had significant beach loss; including an occasional row of houses.
OBJECTIVE: To prevent beach loss, protect and save homes.
SOLUTION: Used the Envirotubes™ to create a barrier dune and protect beach homes from damage due to storm surge and flooding.
Case Study Three
Louisville Gas & Electric Company
The Louisville Gas & Electric Company is a coal burning power generating plant near Louisville, Kentucky. They had a problem in which the sludge ponds that settled out the scrubbings from the chimney were full and overflowing onto the road.
PROBLEM: Tugboats and storm event damage resulted in significant coastline loss.
OBJECTIVE: To prevent additional loss and restore saltwater marsh.
SOLUTION: Used the Envirotubes™ and scour aprons to create a barrier protecting the area to be restored. Material was dredged from Galveston Bay behind Envirotube™ barrier restoring marsh & coastline.
Case Studies - STRUCTURAL
Case Study One
Drakes Creek
Created a peninsula & rerouted a tributary
PROBLEM: Bird waste and sediment were disrupting recreational activities in it's City Park.
OBJECTIVE: To clean the waterway and create a hiking path
SOLUTION: Used the Envirotubes to connect an island to shore re-routing a tributary to flush the stagnant water and bird waste with it into main river.
Case Study Two
Pirates Beach
Installed Envirotubes™ & scour aprons on the beach to core a dune by covering the Envirotubes™ with sand
PROBLEM: With every storm event, the island had significant beach loss; including an occasional row of houses.
OBJECTIVE: To prevent beach loss, protect and save homes.
SOLUTION: Used the Envirotubes™ to create a barrier dune and protect beach homes from damage due to storm surge and flooding.
Case Study Three
Starvation Cove
Installed Envirotubes™ and scour aprons to recreate saltwater marsh & bird/wildlife sanctuaries destroyed by tugboat wake & storm event damage
PROBLEM: Tugboats and storm event damage resulted in significant coastline loss.
OBJECTIVE: To prevent additional loss and restore saltwater marsh.
SOLUTION: Used the Envirotubes™ and scour aprons to create a barrier protecting the area to be restored. Material was dredged from Galveston Bay behind Envirotube™ barrier restoring marsh & coastline.
