On the rise

For public works agencies in St. Louis, Missouri, a deceptively simple way of managing manholes is facilitating maintenance year-round. Adjustable risers are used by utility crews after repaving, in order to keep potholes from forming when water and sewer manholes are below grade. Therefore, snowplows don't end up catching the rims and doing damage when they are operating in the winter. Details as to how the risers function are included in this article.
