CertainTeed Certa-Set PVC Sprinkler System Scores Higher than Aluminum in Distribution Uniformity Test

(Valley Forge, Pa.) – Understanding that for growers greater yield and more efficient water usage is paramount to success, CertainTeed announces that its Certa-Set™ 3-inch Lateral PVC Sprinkler System demonstrated a distribution uniformity (DU) of 84 percent in a recent third-party test by the National Resources Conservation Service (NRCS), a division of the U.S. Department of Agriculture. The product scored significantly higher than aluminum solid set lateral sprinkler systems, which typically have a DU of about 70 percent.

“The results of this test prove Certa-Set’s high-performance capabilities in providing uniform water distribution in solid set sprinkler irrigation,” says Jeff Argus, marketing manager for CertainTeed’s Pipe Group. “With Certa-Set’s high DU, growers are able to lower their water consumption, which is good not only for the environment, but also for their bottom line.”

The test was commissioned by prominent vegetable grower Grimmway Farms, Inc., of Bakersfield, Calif., who was evaluating CertainTeed Certa-Set for use at Dellis Ranch, one of the grower’s carrot farms. Also contributing to the high DU were Nelson Irrigation check valve and pressure regulators utilized in the system. The combination of this equipment and the Certa-Set pipe allowed the sprinkler system to operate at a pressure of 60 pounds per square inch. Since the adoption of the Certa-Set system, Grimmway Farms has significantly reduced its water usage at Dellis Ranch.

CertainTeed Certa-Set provides growers a highly efficient, leak-free solution compared to traditional aluminum irrigation products. With its dual-gasket coupling system Certa-Set saves money with higher uniform water distribution and the elimination of “water puddling” that is common with aluminum piping systems. Manufactured as an impact and corrosion resistant above-ground portable irrigation piping system, Certa-Set laterals and couplings are impervious to sunlight, electrolysis, chemicals and fertilizers. It is designed for easy use in agricultural irrigation, including row crop and turf grass applications, and works particularly well in drag, mechanical move and side-shift operations.
