Moreover, broken drain covers can exacerbate flooding during heavy rains. When debris clogs broken drains, water cannot flow freely, leading to pooling on streets and sidewalks. This not only creates hazardous walking conditions but can also cause property damage. In severe cases, the stress on the local drainage system can lead to overflows, contaminating nearby waterways and posing environmental risks.
Another significant advantage of ductile iron covers and frames is their resistance to corrosion. Urban environments expose infrastructure to various corrosive elements, including chemicals from roadways, saline environments, and environmental pollutants. Ductile iron can be coated with protective finishes, such as asphalt or epoxy, to further enhance its corrosion resistance. This quality extends the life of the product substantially, reducing the need for frequent repairs or replacements and thereby resulting in cost savings for municipalities and contractors.
