Construction of a new shopping center warranted a stormwater runoff system that included both a retention pond manifold with detention system overflow.  Along with the longer runs of pipe, all of the corrugated metal pipe had to be connected to a Type 4 concrete catch basin per ADOT standard Detail C-15-30.  To achieve this feat, three 42” tees were used to connect the longer runs of CSP.

After heavy rains in Northern California, the side of a hill, on the edge of a parking lot, gave way creating a sinkhole approximately 250’ in diameter.  This section of Wolf Creek, directly at the bottom of the hole, handles about ¼ of Grass Valley's stormwater drainage during the heavy season.  After realizing there was a significant sinkhole issue, city engineers, contractors and Pacific Corrugated Pipe worked together to create a solution.

The local high school in Delano, MN decided a renovation to their stadium was in order.  Among the renovations a new detention system was to be installed – under the athletic field!  After consulting with the project engineers and contractors, the school system decided to go with corrugated steel pipe for the system.  

In Labette County, Kansas, a concrete bridge structure was in need of replacement. Originally built in the early 1900s, the structural condition of the bridge was very poor, and the neighboring landowner was experiencing damaging flooding events due to back up from the bridge.

The Stark St crossing over Beaver Creek consisted of an undersized concrete box culvert with a broken fish ladder that was prohibiting salmon and other fish species from migrating upstream through the culvert.  

A bridge project in Antioch, CA needed a very special isolation casing that wasn’t typically available.  Engineers reached out to PCP for their help in designing this mammoth casing.

Since 1993, wet conditions have brought water from the upper reaches of this watershed down to the Michigan Spillway Project area.   The Nelson County Water Resource District Board has worked toward emergency pumping to lower this flood for many years.   This project has had many designs made, with protection for downstream impacts and even concerns of invasive species downstream that could migrate upstream.  Hence, a very elaborate pump station is required to control these issues for this project and was permitted. 

Industry uses of corrugated steel structural plate goes virtually unnoticed by the public and engineering community alike as it does not involve transportation facilities. However, structural plate is integral to the operations of quarrying and mining industries, and Pennsy Supply’s Millard Quarry Tunnel in Anneville, PA provides an excellent illustration of the varied uses of this engineering material.

Ultimately, the IDOT selected a proposal by WBK Associates LTD which utilized a 144-inch diameter polymer-coated double wall pipe supplied by Contech Engineered Solutions. The double walled steel pipe with a polymer-coated, 18 gage, smooth interior steel liner and 12 gage, rugged 3x1 corrugated outer steel shell was able to satisfy the AASHTO specification as well as the IDOT section 543.02 requirements.

A signaled level crossing had been holding up traffic and impacting safety on a BNSF Railway spur feeding the La Cygne Generating Station, south of Kansas City.  Motorists and railway workers alike all gave it a failing grade.

During the design of their new retention system, Watson Industrial Park presented 2 unique challenges.  The first required a product and logistical solution that would allow for the installation to be completed as it was delivered and the second was a production plan that would allow for everything to be produced AND installed in less than 6 weeks time.

To say water is important to the state of Wisconsin would be an understatement. With over 15,000 lakes in direct proximity to Lakes Michigan and Superior (two of the largest sources of freshwater in the world), and 32,000 miles of streams, Wisconsinites prize their quality water resources. They utilize these resources for drinking water, recreational opportunities, crop irrigation, and as the base of a huge tourism industry.

In 2016, the Atlanta Regional Council revised the Georgia Storm Water Management Manual to incorporate LID (Low Impact Development) water quality methods. SEC designed a 42” perforated, aluminized infiltration system that would return the storm water to the soils.

The project specifications called for construction of a conventional temporary bridge in the median to carry the 3 lanes of traffic for the northbound or southbound bridge as that bridge was being replaced.

Pacific Corrugated Pipe was given the opportunity to value engineer and aid in designing one of the largest rainwater storage retention systems ever installed in the Murrieta, CA area and furnished from their facility.

The Bureau of Land Management was in need of a new, eco-friendly culvert solution that would allow for a proper fish passage west of Wolf Creek in Oregon.  In addition to providing safe passage for fish, this new design called for construction loading and heavy vehicle traffic support on 2 one-way logging roads.

Mar-Jac Poultry in Spruce Pine, AL needed an unconventional storm sewer system for it’s new $35 million feedmill.  Because of the nearly 100’ canyon walls at the location, the storm sewer system needed to account for an anticipated height of cover in excess of 80’ – a height that exceeded many allowable limits on all design charts for the typical concrete, corrugated metal and precast box culverts.

A timber bridge in Talpa, TX was in need of emergency repairs after extensive flooding in the area. The project called for a solution that could be designed and implemented quickly as the bridge was part of the local railway system.

The new structure had inside dimensions of 41’4” span and 21’3” rise with an overall length of 200 ft.  The new Buried Bridge consisted of hot dipped galvanized steel deep corrugated structural plate with a corrugation profile of 15” peak to peak by 5½” deep, steel thickness of 0.170” (8 gauge), and overall structure weight of about 155,000 lbs.  The structure was shipped in standard 30” wide plates and was assembled on site using 5 plates per ring.  

A run of CSP totaling 5700 linear feet of 72” diameter (81” x 59”) arched storm drain was designed to accommodate a section of the project where soil conditions were not conducive to open channel ditch construction.

Access points were placed every 400’ for ventilation and cleanout. 48’ pipe sections were supplied to accommodate contractors request to reduce freight, joint connections and equipment limitations.

Aluminized Type ll steel was selected to provide an extended service life.

Using a low profile box culverts kept the project on budget, on schedule and provided a sustainable option.

As the aging infrastructure impact all transportation types, corrugated steel pipe was a solution to the rehabilitation of this old railroad timber structure.

Keeping the transportation running is the most important part of the rehab project. This crossing was not shut down any though the entire installation process.

Standing the test of time these structures have survived nearly 60 years of service and are being extended to accommodate today’s traffic patterns.

Fulfilling the order for this project created challenges in that the diameter was barely able to fit through our fabricating plant door, the pipes were so heavy that up to 3 forklifts were used to lift/transport the product.

The City of Pharr and the Texas General Land Office needed to upgrade a smaller, reinforced concrete pipe (RCP) drainage system that included a main trunk line of large box culverts which intercepted approximately 320 acres of surface runoff in a densely populated area.
