City of Taylor Embarks on Major Water Main Replacement Program with Fusible PVC® Pipe and Static-Pull Pipe Bursting

In February 2013, the City of Taylor, Michigan kicked off an extensive water main replacement program.
Ultimately, 25,780 LF of 8-inch and 12-inch Fusible PVC® pipe would be installed in the tight confines of Taylor’s residential neighborhoods, with the majority of the new pipe replacing 8-inch cast iron water mains originally installed over a half century ago. In order to minimize the disruptive impact of construction, the City decided to install the replacement pipe using trenchless methods.

Approximately 16,780 LF of the project was completed by static-pull pipe bursting, with another 9,000 LF
installed via horizontal directional drilling (HDD). There were more than 400 service saddles installed on the Fusible PVC® pipe throughout the project. The City used the same standard service saddles used with its belland-spigot PVC pipe. The fused pipe strings were charged, chlorinated, and pressure tested prior to pull-in.

DC Water Elects to Reinforce 36” Water Main with Fusible PVC® Pipe Slipline

The District of Columbia Water and Sewer Authority (DC Water) is implementing its Long Term Control Plan to reduce sewer overflows from the District’s combined sewer system into the watershed and, ultimately, the Chesapeake Bay. The work under Division E will occur on M Street SE, between 9th Street SE and 14th Street SE, diverting flow from existing combined sewers through a series of 48-inch and 108-inch diameter diversion sewers constructed by tunneling. The 36” Southeast Relief Water Main (SRWM), under M Street, was determined to be in jeopardy due to possible settlement as a result of construction of the diversion sewers. Therefore, structural rehabilitation options were evaluated and designed prior to construction of the new facilities.

Ultimately, the designer, CDM Smith, chose to competitively bid two rehabilitation methods, pressure cured in placed pipe (CIPP) and sliplining. In evaluating sliplining, both HDPE and Fusible PVC® pipe were
investigated. The final decision to specify 30-inch Fusible PVC® pipe was based on both constructability and the need to maintain flow through the rehabilitated line. The comparison of the two pipe choices is illustrated here:

San Clemente Capitalizes on Fusible PVC® Pipe for Innovative Slipline Project

The City of San Clemente, California has long been considered a gem on the Southern California coastline. The 18 square mile area located on the southern border of Orange County is home to 55,000 residents. The City is committed to responsible use of available water resources to sustain the lifestyle of the community and it continues to expand a robust recycled water distribution system. The City operates a 2.2 million gallon-per-day water reclamation plant for tertiary treatment in accordance with California’s Title 22 program. As with most recycled water projects, the most significant challenge is economical distribution of the product water for beneficial use.

Thinking creatively, the City saw an opportunity to convey recycled water utilizing 16-inch Fusible PVC® pipe slipped into an abandoned cement pipe with a 20-inch inside diameter. This trenchless installation of more than 2,000 feet of fused 16-inch PVC pipe greatly reduced the cost of conveyance since excavation and the associated traffic control was limited. Additionally, the high-strength properties of the Fusible PVC® pipe allowed for the largest possible inside diameter, yielding the maximum carrying capacity for the completed line.

The pull-in operation was completed using a cable winch, with all 2,026 LF pulled into the host pipe during one shift. Connections to the existing system were accomplished with standard ductile iron fittings. Contractor Don Colich said: "We were very happy with the Fusible PVC® product. It worked very well for us on this job. Underground Solutions gave us great support and we worked as a team to complete a very successful project."

Fusible PVC™ is Awarded Project of the Year by Trenchless Technology

The 2010 Trenchless Technology Project of the Year for New Installation brought together everything that is exciting about a challenging project: teamwork, tough subsurface conditions, challenging logistics and drilling under water over a great distance that sets a new standard for pipe performance.

All of these elements successfully converged in New Jersey in spring 2010, resulting in a 5,365-ft HDD project that brought customers of the Middlesex Water Co. a new 24-in. fusible PVC water main that was able to be installed quickly, efficiently and perhaps, more importantly, cost-effectively. Project officials also note that this project set a world-record for distance using 24-in. FPVC.

The project took place in a largely urban area in central New Jersey in Perth Amboy and Sayreville. An overwhelming majority of the project (some 4,800 ft) took place under the Raritan River and adjacent marshland…

6,400 LF Pull of 16” FPVC® Pipe by Beaufort Jasper Water & Sewer Authority and Mears Group Extends Fusible PVC™ HDD Record

Less than three years after the record-setting 5,120 LF Secession Effluent Main project was successfully completed, Beaufort Jasper Water & Sewer Authority (BJWSA), Mears Group, Inc., and Underground Solutions, Inc. (UGSI) have set a new record for the longest single continuous horizontal directional drill (HDD) pullback of thermoplastic pipe.

In September 2008, BJWSA assumed ownership, operation, and maintenance responsibility for the water and wastewater systems at several local military facilities, including the Marine Corps Recruit Depot at Parris Island, SC. As part of the merger, all of the water and sewer utilities are undergoing upgrades and improvements. Due to restrictive Beaufort River discharge requirements, the military wastewater plants at the Air Station and Parris Island will be eliminated with flows diverted to the state-of-the-art Port Royal Island, SC Water Reclamation Facility.

Project: Military Wastewater Consolidation Project
Owner: Beaufort Jasper Water & Sewer Authority
Engineer: Hussey, Gay, Bell & DeYoung (HGBD)
Contractor: Mears Group, Inc.
Location: Beaufort, SC
Length: 6,400 LF
Pipe Size: 16” DR18 FPVC®
Pressure Test: 150 psi for 4 hours
UGSI Contact: Gary Shepherd;
gshepherd@undergroundsolutions.com

The new sewer force main from Parris Island was installed under Archer’s Creek and the surrounding marsh via HDD to ensure minimal impact to the environment. Mears Group mobilized in October 2009 with two drill rigs, prepared to use the intersect method to complete the pilot drill if necessary. Ultimately, the 6,400 LF pilot drill exited on target without requiring the use of intersect technology. The bore hole was reamed out in three passes to a 32” diameter, then prepared by swabbing with a barrel reamer to clear cuttings and reinject clean slurry.

On December 2, 2009, the 6,400 length of fused 16” DR 18 FPVC® pipe was positioned on rollers and pulled into place with an excavator. The pull head was then connected to the drill stem to begin the process of pulling the pipe from Horse Island, under Archer’s Creek, and onto Jericho Island. The pipe emerged during the predawn hours of December 3rd to the applause of the small group of interested bystanders and a much larger number of tired, but satisfied workers.

Ed Saxon, BJWSA Deputy General Manager, commented: “The force main leaving Parris Island became a real design challenge because the narrow causeway linking the mainland was off limits to construction. Open cutting across the salt marsh would also have been very difficult, even had it been possible to permit. BJWSA’s growing body of experience with long HDD installations and recent advances in the technology made drilling the only viable option. Fusible PVC™ pipe was the only practical alternative for us, and we’ve had great experience with Mears Group as well.”

Jennifer Oetgen with HGBD remarked: “The design was critical to a successful outcome; early onsite consultations with representatives from Mears and UGSI confirmed the viability of a 6,400 LF HDD, but the possibility of an intersect drill, staging that length of pipe, and working within the requirements of the military made this project particularly challenging and satisfying.”

South Dakota Fusible PVC Project Sets a Record

In August 2009, King Contracting, Lincoln, Neb., completed a record-breaking horizontal directional drill (HDD) of 4,800 lin ft of 24-in. fusible polyvinyl chloride (PVC) pipe under Lake Oahe near Wakpala, S.D. The HDD crossing was part of an 80-mi raw water transmission pipeline being constructed by the Standing Rock Rural Water Sioux Indian Tribe.

Crossing Lake Oahe was one of the most challenging aspects of constructing the new transmission line because of the lake's length and depth. The original design called for a 3,660-lin ft HDD installation beneath one of the lake's major tributaries. With a depth of nearly 100 ft, the design required 24-in. fusiblbe PVC pipe...

Project Features Pipe Bursting with Fusible PVC™ Pipe System

"The massive Interstate 80 project to replace bridges and rebuild interchanges and roadway along this major east-west corridor has prompted other utility improvements along the way.

One of these—in South Salt Lake, Utah—involved replacement of an aging 18-inch asbestos-cement water transmission line beneath Roberts Avenue. As part of the Utah Department of Transportation’s State Street to 13th East Utility relocation project, the line was one of several water utilities targeted for upgrading due to potential settlement during the road project.
Pipe bursting was selected as the pipe replacement technology by the city and the engineering consultant, Horrocks Engineers (Pleasant Grove, Utah). The reasons were quick installation and the tightness of the site, and because asbestos-cement pipe can be problematic if excavated and removed. Pipe bursting would simply force the pipe fragments into the surrounding soil.

Fusible PVC pipe was chosen for the replacement pipe because of its reduced material costs..."

Fusible PVC™ Sets New Record

Fusible PVC™ continues to set new records with this recent King Contracting 4800 LF 24” DR18 horizontal directional drill (HDD). The high tensile strength of Fusible C-905® allowed for the continuous 14 hour pull-in of the fused pipe under the Grand River inSouth Dakota. Fusible PVC™ joint strength and joint reliability have allowed for plastic pipe pull-ins that cannot be matched by other plastic pipe materials such as HDPE. Other long HDD continuous pull-ins without casings include:
  • 5120 LF 10” Fusible PVC™ in Beaufort, SC
  • 4400 LF 24” Fusible PVC™ in Johns Island, SC
  • 3900 LF 8” Fusible PVC™ in Spirit Lake, ND
  • 2600 LF 20” Fusible PVC™ in Mukilteo, WA
King Contracting also recently completed the 3900 LF continuous pull-in in Spirit Lake, ND.
