Stop Leaking Manholes Leaking manhole covers are a major contributor to rainfall induced inflow. Sewer evaluation studies indicate that a typical manhole casting cover allows an inflow rate from .20 to over 5 gallons per minute during rainfalls. While the manhole cover is one of the leading contributors to collection system I & I, ironically it is the easiest and most costeffective prob-lem to remedy. Stop this unwanted inflow of rainwater with the strong, durable SSI Man-hole Insert. The inserts are custom sized to provide an enhanced fit and seal, and are manufactured from ultra high density polyethylene copoly-mer material known as Marlex HXM 50100. The SSI Manhole Insert can be easily installed by your "in-house" collection system maintenance personnel.
