A $1.5 billion modernization of one of Ohio’s largest interchanges included separating runoff from the City's aging combined sewer system and improving the quality of stormwater runoff coming from the site. As the best water quality solution for the site, four 10-ft diameter CDS® hydrodynamic separators were selected for their ability to fit within a predetermined footprint, provide cost savings, and meet the Ohio Department of Transporation's water quality regulations.
When wildfire removed the vegetation around a watershed, runoff increased and an emergency replacement structure was needed. A round MULTI-PLATE® was selected as the best solution for its quick installation as well as technical and installation support provided by Contech.
When a deteriorating bridge needed to be replaced, HEL-COR® was selected as the best solution for its quick installation, cost savings, and expected service life.
Culverts & Buried Bridges >> Part 1 - Attention to Structure Type, Shape & Size Selection
A key element in selecting a culvert or buried bridge structure is determining the appropriate shape and size to best fit the site. While this seems a fairly innocuous task, it actually brings into play a number of practical and functional issues and concerns related to the decision making process.
Filter Loading: Why Mass Load Capacity Matters in Flow-Through Filters
It is critical to ensure that BMPs have sufficient capacity to handle the expected water quality flow rate or water quality volume, but when it comes to filters, understanding how hydraulic conductivity is reduced as pollutants accumulate on or within the media matrix is equally important.
Ethics lie at the core of all engineering decisions, and the decisions made by civil engineers can affect millions of people. What advice can an engineering ethics expert give to a new professional?
