Sewage Maintenance Access Shafts Feature

The SPEL FG Manhole sewer manhole riser Access Shafts offer great advantages over traditional options. Traditionally, risers have been manufactured from concrete and epoxy lined, but FRP risers offer lighter weight, corrosion resistance, and compressive strengths greater than most concrete products. Another key issue is corrosion resistance. Instead of using PVC liner or some type of coating, FRP offers a solution which you don’t have to worry about corrosion. The contractor receives the benefits of time and cost and the owner gets 100-year corrosion-resistant design. In Sewage manholes, corrosion resistance is a major concern as many systems are designed to provide storage of combined storm and sanitary sewage in the tunnel after a big rain event. As the rain event subsides, the sewage is gradually released for treatment. Storage events can lead to increased hydrogen sulfide, which is then released at manholes due to turbulence. Corrosion resistance of the shafts is as important as the sewer line. With FRP Manhole Access Shafts the corrosionresistant offers the highest life cycle costs of any product.
