Project Summary

In preparation for the City of Calgary Green Line LRT expansion, Morgan was contracted to facilitate the reclamation and reconstruction of the old Ogden Landfill site. The project consisted of lowering the water table by installing a series of caisson sumps to draw down the water table then treating the water and removing all the total suspended solids, metals, and H₂S gases. Upon successfully dewatering the site Morgan was then able to remove any remaining debris and contaminated soils in advance of constructing the new 24^th street pond, walking path, park and LRT track right of way.
