Pollution Engineering - February 2009 - (Page 37) Some Serious SLIPLINING A Chicago suburb completes the longest large-diameter sliplining project on record, rehabilitating the sewer system beneath an affluent college town. By ERIN BOUDREAUX, Marketing Assistant, Hobas Pipe USA E vanston, Ill., part of Chicago’s affluent North Shore region and home to Northwestern University, is directly north of the windy city and shares many common attributes, including its Lake Michigan waterfront. It was also the site of the longest, large-diameter sliplining project on record for the district. Evanston’s combined-sewer system conveys sanitary and storm sewage to the district’s Evanston Intercepting Sewer system, from which the water is directed to their Northside Water Reclamation Plant for treatment. An important component of the intercepting sewer system is a 10-foot, semi-elliptic sewer on Lake Street. One of the more recent projects of the district’s sewer rehabilitation program, the Lake Street sewer rehab project, included 7,000 linear feet of 120-inch semi-elliptic, cast-in-place concrete sewer. “A closed-circuit television inspection of the sewer conducted by the district revealed that the concrete sewer pipe had cracked at a number of places and had lime deposits at cracks and ‘cold’ joints, and the concrete had eroded due to the action of hydrogen sulfide and flowing water,” said Amreek Paintal, engineer of sewer design at the district. Bid documents for the project included various options: segmental sliplining, cured-in-place (CIPP) lining and insertion of panels. Kenny Construction of Northbrook, Ill., submitted the bid with the intent to slipline the sewer. Jack Callahan, vice president of the underground group with Kenny, said, “We thought it would be the most economical option due to timing and the size. We do a lot of CIPP, but this was a little too large for that method, considering the water situation." The pipes were quickly joined and pushed while the flow was maintained.
