Pacific Coast Highway<\/h2>\n\n

The historic Pacific Coast Highway runs along some of the most beautiful coastlines in the United States. Through Newport Beach, California, it\u2019s known simply as the PCH. It winds north along the coast through upscale neighborhoods and shopping areas toward Los Angeles. Visitors travel from around the world to cruise the highway and admire the communities nestled into the coastline of the Pacific Ocean. <\/p>\n\n

Underneath it All<\/h2>\n\n

Below the stunning scenery ran a decades old sewer main, in urgent need of repair or replacement. For a city that relies heavily on the income brought in by tourists, a sewage leak next to the ocean would be catastrophic. The Newport Force Main Rehabilitation project aimed to replace that sewer system before the worst could happen. <\/p>\n\n

ISCO provided high-density polyethylene pipe, McElroy fusion equipment, and expertise for the job.<\/p>\n\n

ISCO representative Joe Chammas added, \u201cIt was a high profile job with extensive risk. ISCO\u2019s size and national high density polyethylene (HDPE) pipe supply presence was required by the contractor in order to have a truly qualified supplier to support a project of this size and exposure.\u201d<\/p>\n\n

\n

HDPE: Pipe That Lasts<\/h2>\n<\/div><\/div>\n\n

HDPE was a clear choice to replace the aging sewer system. “It offers excellent flow characteristics, exceptional corrosion resistance, and the fused-joint system offers reliability,\u201d Chammas explained. \u201cThe pipeline will be leak-free, which is crucial because it\u2019s installed under a major historic highway.\u201d ISCO mainly supplied 8,300 feet of 32-inch IPS DR26 and 3,900 feet of 36-inch IPS DR26 along with fittings raging from 11 \u00bc degree elbows through 45 degree elbows, including 22 \u00bd degree elbows and concentric reducers. ISCO also provided nearly 50 fabricated spooled access tees, ranging in size from 36-inch DIPS down to 32-inch IPS. Not only that, ISCO fabricated stainless steel tops as part of the access tees. \u201cWe were able to provide alternative options for fabricating the complicated manway structures that were a major part of the force main pipeline,\u201d said Chammas. \u201cThe pipeline size, length, and layout of a double barrel pipeline installed in a single trench required the availability and support of multiple HDPE fusion machines in order to install the pipeline in a timely manner. ISCO’s large fusion equipment fleet met the contractor\u2019s needs. We never said no and always made it happen.\u201d <\/p>\n\n

\n

Technical Expertise and Support<\/h2>\n<\/div><\/div>\n\n

ISCO offered corrosion-free, leak-free HDPE, McElroy fusion machines, and fittings all backed by technical expertise and support that can\u2019t be found anywhere else in the world.<\/p>\n\n

Traffic along the highway was reduced to one lane in each direction to complete the nearly $40 million project. That\u2019s why longevity was a key factor in selecting the pipe for the job. \u201cDuctile iron, you have joints that could leak. It degrades faster than polyethylene does. With ductile, you always have infiltration. With [HDPE], when you butt fuse, you really don\u2019t have that issue, Chammas explained. <\/p>\n\n

At the end of the day, the City of Newport Beach will never notice more than a lane closure and it will reap the benefits of a reliable, cost-effective sewer system that will last for decades more to come.<\/p>\n","protected":false},"excerpt":{"rendered":"
