In 2008, the Sacramento County Airport System broke ground on the largest capital improvement project in the history of the County of Sacramento: "The Big Build". Designed by Corgan Associates, Inc., the $1.03 billion terminal modernization project replaced the airport’s original, aging Terminal B to meet the rising demand for passenger services and improve the airport’s ability to attract new carriers and routes.

Sacramento Int'l Airport finished installationThe specifications called for Dura Slope as the drainage solution due to its ease of installation and proven performance.  In an effort to use the highest quality construction while promoting a consistent aesthetic vision, Corgan wanted the strength of cast-iron with the look of steel.  Much to Corgan’s appreciation, NDS quickly accommodated this request and painted the cast-iron to imitate galvanized steel.

The Dura Slope trench drain system consists of neutral and pre-sloped sections of trench drain.  Manufactured from HDPE, this trench drain offers a durable alternative to concrete channels saving time and reducing the cost of installation.  NDS Dura Slope is a high quality, dependable and best in class trench drain system that meets a variety of drainage needs.

Valley Crest Contractors was able to install the product quickly due to the lightweight nature of the material.  The reduction in labor resulted in significant cost and time savings.
