California's Capital City Selects Fusible C-905® Pipe for Downtown Potable Water Slipline Project

The City of Sacramento has been working for several decades to replace approximately 63,000 LF of riveted steel water transmission mains that were installed between 1870 and 1950. To date, over 37,000 LF have been replaced, with many sections of removed pipe displaying severe corrosion, including some holes penetrating through the entire pipe wall.

One recent project involved replacing 2,500 LF of 24" riveted steel main constructed in 1903 in the busy downtown area. To minimize disruption, slipline installation was selected for a 1,500 LF section of the project on 6th Street, between Capitol Mall and Q Street. During the design and evaluation phase of the project, the City considered Ductile Iron, Fusible PVC®, and HDPE as pipe material options for the slipline section.

The City ultimately selected 18" DR18 Fusible C-905® pipe for its ability to deliver a 235psi pressure rating while providing the largest flow area per outside diameter (OD) of the evaluated pipe options. Fusible C- 905® pipe also allowed the City to use standard MJ connections for fire hydrant and valve connections, eliminating the need for specialty fusion skills or stocking of specialty parts for future maintenance.

Project bids were opened on August 19, 2009, with Martin General Engineering, Inc. (MGE) of Rancho Cordova, CA declared the lowest responsive bidder. In March 2010, Underground Solutions, Inc. (UGSI) contracted with MGE to provide 1,500 LF of 18" Fusible C-905® pipe and fusion services for the project. Installation was successfully completed in late May and early June of 2010, including pressure test and reconnection.

Stu Williams, Project Engineer with the City of Sacramento, stated: "For this project, sliplining was a good choice to minimize neighborhood disruptions. The City chose Fusible PVC® pipe from Underground Solutions because it's compatible with standard fittings, is flexible, and doesn't corrode. Underground Solutions' staff was very helpful during design and construction. They are firmly committed to their product and all the contacted references helped reinforce the City's choice of Fusible PVC® pipe. The product was delivered when promised, installation was very straightforward, and Underground Solutions' staff was extremely responsive."
