Yelomine pipe provides irrigation for native plant rehab project.

About 30,000 feet of 4- and 6-inch Certa-Lok Yelomine PVC pipe, by CertainTeed, is being used as part of a temporary above-ground irrigation system project that is restoring 120 acres of land in Walnut Hills, CA, near Los Angeles, to return native plant species to the area.

The project, which is expected to take about five years, began last summer and involves the reintroduction of native southern California plant species such as the California sage, toyon, laurel sumac, oak and walnut trees and coffeeberry. Labeled the Walnut Hills Habitat Mitigation, it is a form of land restoration required by the U.S. Fish and Wildlife Agency and the U.S. Army Corps of Engineers to return land to its natural condition as mitigation for a proposed housing development. Builder Standard Pacific Homes Inc. plans to develop the adjacent land for housing.

Standard Pacific hired native habitat restoration contractor Nakae & Associates Inc., of Irvine, CA, to remove non-indigenous plant life from the land and reintroduce indigenous plants. Nakae & Associates are using the Yelomine pipe as a temporary above-ground mainline, which feeds water to the lateral lines of the overhead irrigation system. The contractor will water and cultivate the various plants for the next two to three years and the plants will be maintained for another two years, once the irrigation systems are removed. The Yelomine was purchased from the Irvine branch of John Deere Landscapes. Nakae & Associates chose Yelomine pipe for its temporary mainline because of the product's easy assembly, which speeds up operations.

"One of the best things about Yelomine is that we can easily disassemble it, move it to the next site and set up a new temporary mainline there," says Kevin Kirchner, vice president and general manager of Nakae & Associates. "It's been working really well for us. We used to use 4-inch rubber hose material for this application, but the Yelomine pipe has been a big improvement."

"For more than 30 years, Yelomine has been making a name for itself with its groundbreaking restrained joint system and strong performance," says Steve Gross, director of marketing for CertainTeed's Pipe & Plastics Group. "The 20-foot lengths of pipe can be easily assembled using spline-locked PVC couplings. Yelomine is a very versatile product, ideal for both temporary and permanent installations."

Yelomine pipe is made from a unique, modified PVC formulation with increased sunlight- and impact-resistance, making it perfect for use in aboveground applications where conventional white pipe may not offer the required long-term performance. Its spline-lock joining system reliably holds the pipe together when pressurized. Besides irrigation, Yelomine is also ideal for a variety of other critical applications, including water and sewer bypass lines, mining, and trenchless construction projects.
