The Atlantis tank system installation consisted of a 71.96 m³ ( 2541 cf) detention tank installed under a parking lot. The underground detention system receives surface run-off through a network of catch basins connected to the tank by underground pipes. The depth of cover above the tank is 600 mm (23.6″) to substantiate H 20 Vehicle loading requirements.
The water will drain into the existing municipal storm sewers through a controlled outlet. By managing the storm water locally and delaying its release, this tank will prevent local flooding and stream erosion during heavy storms.
