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.

In March of 2016, Crittenden Co., KY decided to replace a structural plate bridge built in approximately 1945.  This bridge is located in the most northern part of the county on Hurricane Church Road, approximately five miles south of the "Cave in Rock" ferry, which still crosses over the Ohio River many times each date.  This bridge has allowed safe passage over a tributary of Caney Fork Creek for many years providing access to the historic Old Hurricane Methodist Church and Cemetery where you can find some of the oldest graves in Crittenden County - some dating back before the Civil War.

Original plans for a new Chrysler Dealership in Pineville, NC included a modular reinforced concrete storm water detention system – but at a hefty price. After a value engineering process, it was decided to go with an aluminized steel pipe combination storm water management system, saving the owner over $300,000!

This bridge allowed passage over Fish Creek. The updated design required a 5 gauge, 22’x 20′ vertical ellipse, galvanized multi-plate for the main channel with a length of 150′.

On either side of the vertical ellipse a round 14′ diameter, 7 gauge, galvanized multi-plate overflow structure completed the design. Each overflow structure was 140’in length.

A 6” minimum benign envelope around the pipe using pea gravel was incorporated to abate the poor resistivity readings that periodically occurred at this site.

This job consisted of 6300 LF of CSP and 3200 LF of spiral rib pipe including several large tees, elbows, & misc. fittings.

With over 14,680 LF (sections varying from 4,594 LF of 15-in diameter to 5,162 LF in 42-in diameter and 263 LF in 60-in), the mobile mill offered the perfect flexibility for the variety of pipe diameters needed to complete the job.

These pipes are set vertically into a concrete base and sealed with silicone or a spray sealant. They are then covered with a solid vented lid and plumbed for use.

Corrugated steel water tanks are designed to be an aesthetically pleasing and cost effective solution used for  rain water harvesting.

The deteriorating culvert had experienced major encroachment along the toe of the slope after a major rain event and catastrophic washouts.

The North Dakota Department of Transportation had a problem with joint separation and spalling concrete in a 10’ x 8’ cast-in-place Reinforced concrete box culvert built in 1934, and extended in 1960.

Constructed in 2011, this is the longest single span box culvert of any material in North America. This was also the first large span steel buried bridge to take advantage of its flexible nature in the foundation design.

This half-round CSP structure, with its own footing plates, was designed by Pacific Corrugated Pipe Co. for bridging small streams on a temporary basis. The installation was along the Smith River access road near Elkton, RO and completed under the auspices of Oregon Department of Fish and Wildlife to ensure compliance with environmental regulations.

To provide ample drainage along the bottom of  a ravine, 863-foot long 96″diameter structural steel plate was installed as part of the $23.4 million Coalfields Expressway corridor improvement project.

NCSPA member Southeast Culvert worked with engineers to re-design the project to pre-treat the detentions using multiple 144″ CMP filters.

Contech Engineered Solutions worked closely with the design-build team to design and manufacture a storm drainage system beneath the new interchange

In 1994, BNSF Railway usedOver 26,000 ft of Aluminized Type 2 (ALT2) spiral rib pipe and  helically corrugated culvert pipe to build there intermodal facility in Roanoke, Texas

The Minnesota Department of Transportation (MnDOT) designed a 144-inch by 180 feet of 10 gauge,  Aluminized Type 2, CSP as the replacement.

An 80-foot run of 8 gauge, polymer-coated, arched pipe with a 137-inch span and a 87-inch rise was installed at Southwestern Illinois College

The University of West Georgia has installed a  three-tank system using 96-inch Aluminized Type 2 CSP.

Originally constructed in 1906, the relining design engineer of this project specified two 22-ft long, 19′-0″ x 5′-9½” structural plate arches.

Located near Philadelphia, a combination system irrigation/detention system with of 1,584 feet of fully perforated, 96-in diameter, aluminized corrugated steel pipe (CSP) epitomizes "Green Infrastructure".

The U.S. Bank Stadium, home of the Minnesota Vikings, installed an underground retention system made from 1,000' of 144" diameter perforated Aluminized Type 2 (ALT2)  corrugated steel pipe.

The structural plate arch built to help protect visitors from falling results, with the help of NCSPA member Lane Enterprises, had unique specifications to accommodate a local endangered species.

Deep corrugated steel arch provides minimal disruption on New Mexico State highway

Corrugated steel pipe was introduced to this North Dakota town's stormwater system, in response to the  major flooding events plaguing their land.

NCSPA member Big R Bridge utilized corrugated structural steel plate to develop an efficient, yet economical construction solution.

Manufactured from corrugated steel pipe, slotted drain fabricated by NCSPA member Contech Engineered Solutions was selected to complete a recent construction project
