Orenco in the News


Onsite Installer, August 2009: "In Time for the Bell"

"Plumbing a new subdivision, four restaurants and several businesses into the Breitling Elementary School Waste Water Treatment Plant in Grand Bay, Ala., threatened to overwhelm its 30,000-gpd onsite system, sized to handle the school and a truck stop." The solution included nine of Orenco's AX100 modules and a ProSTEP effluent pumping system.

Water Environment and Technology Magazine, March 2009: "Small, Green, and Useful"

"Decentralized wastewater treatment systems have the potential to provide a critical infrastructure element of wastewater treatment in a cost-effective and beneficial manner, as well as enable green development and more efficient land use, helping meet this population demand.

"U.S. Environmental Protection Agency (EPA) asserts that ... 'adequately managed decentralized wastewater
systems are a cost-effective and long-term option for meeting public health and water quality goals, particularly in less populated areas.'

"Experience with decentralized systems in several southeastern states has demonstrated their benefits and provided models of sound management to ensure successful operation at an affordable cost ... 'These STEP systems in the Mobile (Alabama) area represent a significant performance improvement over traditional septic tank and drain field developments of the past, and have provided savings of 25% to 50% over centralized collection and treatment.'"

Water Environment and Technology Magazine, March 2009: "O&M Considerations for STEP Systems"

"An ever-rising number of communities and new developments are choosing wastewater management
solutions that use alternative wastewater collection system technologies, such as the septic tank effluent
pump (STEP). STEP systems collect wastewater from each property in an onsite ... interceptor tank and then pump screened primary effluent to a treatment facility or neighboring sewer. Most organic solids are retained in the tank to degrade anaerobically while the screened effluent is conveyed offsite through small-diameter, shallowly buried pressure mains.

"Applied properly, STEP wastewater collection systems can offer several benefits for existing
communities and new developments, including reduced upfront capital costs, lower lifecycle costs, and
lower treatment costs than conventional gravity sewer collection systems."

WaterWorld, February 2009: "Effluent Sewer Technology Saves Excavation Cost on Sewer Rehab Project"

"Older sewers are often plagued with inflow and infiltration (I&I), increasing flow and potentially overloading pump stations and treatment plants. Because of the difficulty of finding and correcting sources of I&I -- especially sources on private property -- and because of the high cost of replacing or repairing gravity sewers, communities often deal with this problem by simply accepting increased I&I and upsizing the treatment plant to accommodate the extra water.

"A simpler solution is to replace the gravity collection system with an effluent sewer system. Effluent sewers use small diameter (2-in.) pipe that can be “sleeved through” larger, failing gravity pipes using trenchless technology. For a Rhode Island developer, this particular benefit eliminated an unpredictable excavation cost and made a 2008 sewer rehab feasible."

Onsite Installer, January 2009: "Many of a Kind"

"A flood in 2006 washed out an upstream dike, inundating the 150-home Alpine Woods subdivision on the Lowe River, built in the mid-1970s, 10 miles north of Valdez, Alaska. The development was unsewered. Fearing contaminated wells, city officials sampled them and found coliform bacteria.

"The flood helped bring to light improperly sized onsite systems, faulty installations, failed drainfields, ponded sewage within 10 feet of salmon streams, and the occasional homemade 55-gallon-drum septic tank.

" ... The solution was a pre-plumbed, pre-wired, fully assembled treatment package for each lot, with textile media filter and ultraviolet disinfection ... System components, shipped nested together, arrived in Anchorage on a barge. Orenco representatives instructed Tom Varney, AdvanTex coordinator at Anchorage Tank, and his employees how to assemble the parts. "

COWA News, Winter 2009: "IWS Helps Keep Critical Regional Hospital Online"

"IWS completed construction of the renovated and greatly expanded onsite wastewater system of Feather River Hospital (FRH), located in paradise, CA in January 2008. The new system will accommodate flows of up to 40,000 gallons per day and was designed to meet the needs of the (facility's) five year expansion plan. FRH now has one of the largest Orenco AdvanTex Treatment Systems in California. Work was completed by IWS while the hospital remained in full operation."

Plumbing Connection, Spring 2009: "Treatment is a Lifestyle Choice"

"There are dozens of systems appearing on State approved lists (including septic tanks, aerated wastewater treatment systems and sand filters) that offer individual residential wastewater treatment systems ... It would be easy to think the market is saturated. However, Innoflow Technologies (Australasian agent for Orenco Systems Incorporated) business
development manager Dion Tucker begs to differ.

"' ... Homeowners need an alternative that doesn’t adversely affect their lifestyle, offers better whole-of-life cost advantages, and is a greener alternative for the environment.'

"Since 2000, 20,000 AdvanTex® systems have been installed through North America, New Zealand and parts of Europe. This Orenco Systems Incorporated product is now being rolled out in Australia."
