Manhole rehabilitation has improved significantly over the past couple decades, and composites are playing a big role.
Chad Nunnery started his career in composites manufacturing after graduating with engineering and chemistry degrees from Dartmouth College in 1994. He set up and managed composite businesses in Latin American countries where he first witnessed nonmetallic manhole covers being used primarily for theft prevention. After analyzing other material benefits, he realized that composites would solve additional problems like inflow, SSOs, corrosion, weight, data transmission, asset management, install efficiency and environmental impact.
