Orenco in the News


Water & Wastes Digest, September 2014: "Portable Treatment"

"BGP Intl., a seismic surveying firm, needed portable wastewater treatment systems for a series of 500-person remote camps in Kurdistan, Iraq. Units needed to be robust enough to meet treatment limits with minimal maintenance and simple operation.

"After viewing a similar system in operation at a mining site in Texas, BGP chose two (Orenco AX-Mobile) portable wastewater treatment systems. The plug-and-play system produces effluent suitable for reuse (subject to local regulations) and is easy to ship, set, operate and move."

GreenBuilder, September 2014: "Better Treatment"

" ... The EPA estimates that replacing our ailing infrastructure will cost around $298 billion over the next 20 years. But onsite or decentralized wastewater treatment offers an inherently sustainable alternative. Wastewater doesn't have to travel long distances, reducing pumping energy and the chance for contamination via leaky pipes. Some systems require very little (or no) energy to operate. Treated effluent (the liquid portion of wastewater) recharges groundwater, or can even be used for irrigation or toilet flushing, which reduces the demand for potable water ... As communities contemplate how to replace aging systems, and as people become more concerned about water security, interest in onsite systems is likely to spike."

Water & Wastes Digest, August 2014: "Examining 'Small-Pipe' Solutions for 'Big-Pipe' Problems"

"The American Society of Civil Engineers estimates that almost $289 billion in capital improvements for wastewater will be required over the next 20 years—and three-quarters of that amount is needed for “big pipe” problems. WWD Managing Editor Elisabeth Lisican recently spoke with Grant Denn, senior manager of engineering projects for Orenco Systems Inc., about these problems and some viable solutions ...

" ... Lisican: What are some benefits of decentralized wastewater treatment systems as a solution to these [big-pipe] problems?

"Denn: The main benefits are the low lifecycle costs and environmental stewardship. Decentralized systems are ideal for a smaller customer base, and they are environmentally friendly due to the elimination of inflow and infiltration, low power consumption, and low O&M costs. The whole system is watertight, and primary treatment (of solids) occurs on lot at the point of generation; so treating and reusing the remaining water is simplified and energy- and water-efficient."

Water Efficiency, July-August 2014: "Water Quality Testing and Innovative Treatment Approaches"

" ... The Audubon Society sought to construct an environmental education center in the Ernest E. Debs Regional Park in Los Angeles, CA, to serve as a model of green architecture and the first Leadership in Energy & Environmental Design (LEED) Platinum-rated facility in the world. One of the criteria in doing that was a wastewater reuse option. Enter Steve Braband, company president of BioSolutions, a company that provides products and services for the wastewater industry, specializing in providing complete site-specific packages for decentralized wastewater, one of which is an Orenco-manufactured AdvanTex Textile Treatment System.

"The Audubon Society got the city’s approval to go off of the sewer grid to capture, treat, and reuse wastewater with the system. The quality of the treated water is high enough to be reused for subsurface drip irrigation.

"In January 2004, the Audubon Society earned 53 LEED points and was awarded the first Platinum rating in the history of the LEED program. High marks came through the use of the efficiency of the AdvanTex wastewater treatment system. Of particular note is that the center was designed to use 70% less water than a comparable conventional building and that the wastewater is being treated onsite."

Water Efficiency, July-August 2014: "Boy Scout Jamboree Site Adopts Water Reuse"

" ... How to deal with wastewater at The Summit, which has been designed as a flagship sustainability project for the BSA (Boy Scouts of America), presented a challenge. The solution: graywater would be processed on site in a manner that would not only have the lowest impact, but offer the highest yield in beneficial use by treating water from each building’s showers and sinks for use in toilet flushing.

"Orenco Systems was selected to provide AdvanTex AX-RT advanced wastewater treatment. Clear, odorless, reusable effluent is produced through a pre-packaged 'plug and play' AX20 wastewater treatment system. UV disinfection also is available for the system."

Onsite Installer, April 2014: "Linked In"

"As demand for sites at a mobile home park in Cedar Point, N.C., developed, the owners added more spaces with sewer connections. The increasing volume eventually overwhelmed the low-pressure pipe drainfield in the center of 96 lots.

"Pumping the 5,000-gallon septic tank every other day prevented ponding and odors. During the system’s permit renewal, the Carteret County Health Department inspector identified the situation and issued a consent decree.

"President Greg Mayfield of Southern Water and Soil in Zephyrhills, Fla., worked with Orenco Systems’ distributor Steve Barry of AQWA in Wilson, N.C., to design a replacement system. They chose AdvanTex technology partially due to space restrictions, but primarily to reduce nutrient loading to protect sensitive aquatic life in the adjacent Intercoastal Waterway."

Water, Environment, & Technology, March 2014: "A STEP Above the Rest?"

"The City of Lacey, Wash., has operated a gravity sewer for decades with an understanding that customer satisfaction and low life-cycle costs are the result of a well-balanced operations and maintenance (O&M) program. Too little maintenance leads to premature equipment failure and dissatisfied customers. However, too much maintenance leads to high costs. An early adopter of septic tank effluent pumping (STEP) sewers, the city worked with its STEP equipment manufacturer to develop O&M protocols that provided a similar balance between maintenance and cost-effectiveness for STEP systems."

Water Online, March 7, 2014: "Biological Treatment 101: Suspended Growth vs. Attached Growth"

"No one knows it all. Not in life, and not in the complex world of wastewater treatment. Nearly every day I talk to industry practitioners — from front-line operators and engineers to PhD’s and CEOs — and I’m reminded that we’re all at different points on the learning curve. For those who aren’t well-versed in secondary (biological) wastewater treatment and the differences between traditional suspended-growth processes and attached-growth processes, this article is for you.

"An assist comes from Orenco Systems’ Grant Denn, Senior Manager – Engineering Projects, who provided a 'layman’s description' of how the technologies differ (from his perspective as a supplier of attached-growth solutions). For balance, as well as a bit more technicality, I also consulted research papers evaluating the two processes. It remains, however, a '101' — plainspoken and hopefully helpful."
