Storm Impacts on Existing Infrastructure
As existing storm water infrastructure nears end of life or was designed for situations that are no longer present, engineers and owners must find ways to deal with these impacts.
Arrowsmith Project Management Limited was contracted to function as quality assurance for the owners representative on the installation of significant storm water outfall upgrades.
Old corrugated spiral pipe was uncovered, removed and a new larger diameter concrete pipe, headwall and spill way were installed complete with proper sloping and rip rap materials to withstand increasing storm intensities.
