Innovative Joint Proves Successful in Critical Slipline Project
Ever-tightening budgets are forcing water system owners to rehabilitate their major water transmission mains with permanent solutions, a key approach in their asset management programs. Halifax Water was recently faced with a deteriorating Prestressed Concrete Cylinder Pipe (PCCP) water transmission main that needed rehabilitation or replacement. This transmission main is located under Kearney Lake Road, a main high traffic level corridor on the west side of Halifax. The use of Spirally Welded Steel Pipe (WSP) with a unique O-ring rubber-gasket joint, allowed Halifax Water to successfully rehabilitate 4,920 LF (1.5 km) of a 48-inch (1200 mm) host PCCP primary transmission main by sliplining. This fully structural lining system provided a structurally independent solution designed to last 100 years. This paper details the innovative use of polyurethane lined and coated Steel Pipe with the unique joint that eliminated liner pipe bells and ensured that maximum internal flow area was provided by the lining system.
