Soil Scientist Notes the Advantages of Textile Filter Technology


High-density septic systems in and around Bend, Oregon, were contributing to nitrate pollution of the aquifer. With the population projected to increase dramatically over the next several years, nitrate levels were expected to rise even further. But development was too scattered for the installation of a centralized sewer system.


The Environmental Protection Agency (EPA) funded a demonstration project in La Pine, Oregon (30 miles south of Bend), with the goal of jumpstarting the use of innovative, decentralized wastewater treatment systems to solve the problem of excess nitrates. Orenco® provided two different types of AdvanTex® Treatment Systems for the project.
