This article discusses the Lake Street sewer rehabilitation project, one of the most recent projects of the Metropolitan Water Reclamation District of Greater Chicago (the district). After considering several options, the district selected slipling with HOBAS centrifugally cast, fiberglass‐reinforced, polymer mortar (CCFRPM) pipe for the rehabilitation project. The thin‐walled HOBAS CCFRPM pipe provides increased flow capacity because of its superior hydraulics compared to the existing sewer. Project challenges are discussed, along with maximizing internal diameter, eliminating one of the three installation shafts, and controling the water force during installation to eliminate friction from occuring.
