Orenco Technologies

Orenco was founded in 1981 by engineers dedicated to finding solutions for the real world.  Over the years Orenco has continued to invest in new and improved products and processes to provide safe and affordable wastewater systems and high-quality fiberglass products for a variety of markets.

Our Technologies

Effluent Sewer

From on-lot interceptor tanks, only filtered liquid is discharged through small-diameter, shallow collection lines to common downstream treatment, whether that is a neighborhood system or a municipal plant miles away.


AdvanTex Treatment

Textile sheets in AdvanTex filter pods produce clear, high quality effluent. Modular construction allows for phased installation of total treatment capacity. The simple, yet highly reliable packed bed filter has demonstrated success in treating a variety of waste streams as well as highly variable flows.


Nitrogen Reduction

Whether you're aiming to meet limits for Ammonia, Total Nitrogen, or TKN, Orenco can help  you find the right solution.




Orenco designs and manufactures control and monitoring panels for customers all over the world. Our panels are used in water, wastewater, and industrial process applications.



Industrial/Utility Fiberglass Products

Orenco has been in the business of manufacturing fiberglass products for over 30 years. This expertise helps us create tanks, structures, and other industrial/utility products that are lightweight, corrosion resistant, and strong. We use vacuum bagging, resin transfer molding, and filament winding manufacturing processes.


Covered by one or more Orenco patents.
