Keeping aging manholes watertight is often a constant struggle for contractors. Those manholes play a key role in protecting assets below the surface by creating a seal between aboveground contaminants and the belowground access point. But when inflow from surface water or infiltration of groundwater through defects in the structure come into play, the treatment of these excess flows turns costly, unnecessarily testing collections system limits and capacity at treatment plants.
RedZone Robotics, a U.S.-based robotics firm, recently introduced a new technology for manhole condition assessment aimed at reducing the risk of sanitary sewer overflow events caused by faulty manholes. Vertue
