Project Profile:

City of Denver Storm Water Detention- Federal at Arkansas

Project Summary

The two Rainstore3 detention chambers utilize geo-grid below and above with a heavy filt fabric wrapping the 3 unit high by one unit wide system. Between the street and the chambers and the sidewalk and the chambers there is a 20 mil PVC liner 4-5’ deep to keep any water from getting under the street or sidewalk. The water can only percolate directly below into the soil.
