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."

Sliplining Rehabilitates Critical Water Supply Line

It’s tough to imagine a more difficult job than rehabilitating a water pipeline passing 25 ft beneath an interstate highway bordered with steep embankments in a busy tourist area, but that’s what the Las Vegas Valley Water District faced. BY JIM FORCE
