The longest horizontal directional drilled (HDD) installation of high-density polyethylene (HDPE) pipe in the United States and Canada was recognized as Project of the Year by the Plastics Pipe Institute, Inc. (PPI). The award was presented to PPI member company ISCO Industries at the association's annual membership meeting in May 2017. PPI is the major North American trade association representing all segments of the plastic pipe industry,
"Not only was this a very long pull," stated Tony Radoszewski, CAE, president of PPI, "but the diameter of the pipe was also a challenge in replacing the existing sanitary sewer line in Miami Beach. More than 4,200 feet of 54-inch diameter HDPE (PE4710) pipe was used. This was quite an accomplishment and we were pleased to present the Project of the Year Award to ISCO."
Failure of this force main, which is the only means of wastewater conveyance for the city's nearly 92,000 residents, would be disastrous. It could potentially discharge millions of gallons of raw sewage along the urbanized corridor of one of the most popular tourist destinations in the world. This would impact residents and commercial operations, threatening contamination of pristine, ecologically-sensitive waterways, beaches and parks in this scenic area. The economic impact of forced closures of hotels, restaurants, and tourist attractions and businesses would devastate the city.
The existing 54-inch pre-stressed concrete cylinder pipe (PCCP) sanitary sewage force main (FM) was constructed in 1977 and served as the sole means of wastewater conveyance through Miami Beach. By 2012 it was deteriorating like much of the infrastructure in coastal communities. Faced with the potential threat of failure, the city embarked on a Capital Improvements Program, totaling $750 million during five years. In 2013, the city invested in a non-destructive condition assessment. Using Pure Technologies' PipeDiver, the PCCP FM pipe was analyzed and it was determined that the line was on the verge of catastrophic failure.
