"Myth Busting: The Value of an Interceptor Tank in Effluent Sewer Systems”

"An interceptor tank, as part of an effluent sewer, provides low- cost, low-energy primary treatment of wastewater."

"Treatment process savings due to lower-strength wastewater from an effluent sewer include reduced energy demand, reduced chemical use, less biosolids handling, and less biosolids disposal. These combined expenses can make up a substantial portion of the total wastewater treatment cost." Read More >

"Effluent Sewer and Treatment System Solve Wastewater Crisis”

"In 2007, the picturesque community of Piopio, New Zealand, was on the verge of a wastewater crisis."

"Residents may not have realized the urgent need for a sewer and sewage treatment system, but the governing Waitomo District Council had identified the town as qualifying for wastewater funding through the national Ministry of Health. After a thorough bidding process that considered various treatment options, the Council chose an Orenco Effluent Sewer and AdvanTex Treatment System, given its robust treatment and low operating and capital costs." Read More >

“2018 Top Water & Wastewater Projects: Riviera Utilities”

"Riviera Utilities’ primary goal with its project was to design a cost-effective and reliable treatment system to replace the intermittent sand filter being used to treat wastewater from the Diamondhead community near Hot Springs, Ark. ..."

"The utility had received an engineering proposal for a sequencing batch reactor (SBR) treatment facility at an estimated cost of more than $2 million ... The company instead contacted PMI, an engineering services firm. PMI recommended a two-stage treatment process: recirculating media filters (RMFs) followed by Orenco AdvanTex AX100 wastewater treatment systems. This would cost one-third as much as the SBR proposal and would reduce the long-term costs of operation and maintenance." Read More >

“Adjust the System”

"Effluent sewer systems can benefit small communities and isolated developments, including reducing up-front capital costs, lowering life-cycle costs, improving system performance at low flows, reducing maintenance, increasing reliability and decreasing operation requirements. These can save utilities thousands of dollars in up-front and life-cycle costs.

"With decentralized collection technologies available — such as effluent sewers — communities and utilities should consider implementing impact-fee adjustment for specific users based on organic, hydraulic and operational impacts. With this billing system, those using technologies that reduce the impact on the wastewater collection and treatment system pay lower fees." Read More >

“Responsible Water Recycling: Decentralized Solutions for Water Reuse”

"Increasing demands on the planet’s limited fresh water supply are a source of immediate concern. In many places, demand exceeds supply. By implementing effective treatment technologies and reuse strategies, the effects of drought and population growth on water supplies can be alleviated. Decentralized water reuse solutions can play a pivotal role in water conservation and management. Properly treating waste-water – both blackwater and greywater – at or near the point of generation relieves pressure on potable water resources and provides many other environmental and economic benefits. Decentralized systems also minimize environmental footprints, increase opportunities for public education and awareness, and provide for a more sustainable future." Read More >

“A Decentralized Solution for a Small Village”

"Christiansburg, Ohio, was experiencing serious issues with failing onsite wastewater systems. Septage odors were common, especially after heavy rainfalls, and the Ohio Environmental Protection Agency (EPA) detected high levels of fecal coliform in nearby West Honey Creek in 2012. Village leaders stepped up their efforts to seek a cost-effective system for wastewater collection and treatment ..."

"After reviewing cost comparisons, [village] council members decided that an effluent sewer followed by packed-bed treatment was their most cost-effective option. It also offered the ease of operation that would enable the village to affordably manage its own facility." Read More >

“How to Compare Sewer Technologies Using Life-Cycle Cost Analysis”

"Pressure sewers can provide affordable service to municipalities, new subdivisions, and areas where gravity sewers are difficult and expensive to install. Effluent and grinder sewers are today’s dominant pressure sewer technologies. When evaluating these two options, lifecycle cost analysis is an effective tool for comparison, especially when actual costs can be used."

"In 2010, the Water Environment & Reuse Foundation (WERF) developed two reliable resources for evaluating sewer technologies: (1) a “Wastewater Planning Model,” allowing users to compare life-cycle costs and (2) a series of collection system “Fact Sheets” for different types of sewers, including design characteristics, performance, and cost estimates. When performing life-cycle cost analysis using WERF’s documented figures, it’s evident that pressure sewers can be an affordable option." Read More >

“2016 Top Water and Wastewater Projects: Vero Beach Sewer System Extension”

"Until recently, approximately 1,500 failing septic systems served large portions of Vero Beach. These systems were degrading the Indian River Lagoon adjacent to the city with excessive nutrient loads and pollution ..."

"Robert Bolton, director of water and sewer for the city of Vero Beach, began investigating other options. He settled on an Orenco effluent sewer system, also known as a Septic Tank Effluent Pump (STEP) system, which was estimated to cost $11 million in comparison to the original $22.5 million proposal [for gravity sewer]." Read More >

“An Iowa Farm Community Finds Solution to Wastewater Woes”

“The State of Iowa determined it was time to modernize the wastewater system in Woden, a cluster of homes in the rural north-central part of the state … The previous system consisted of individual septic tanks for each home, but they discharged into a ditch that ran into the channelized Lindsey Creek along the eastern side of Woden. Replacements are being ordered for direct discharge systems across the state.

“… Engineers from Jacobson-Westergard & Associates in Estherville, Iowa, designed a system to handle the community’s wastewater without the expense of a small treatment plant. Each property received a 1,600-gallon concrete septic tank … These are dual-chamber tanks with half dedicated to settling and the other half housing an Orenco Systems model PF100511-30 effluent pump package with floats already in place. The tank provides settling and primary treatment.

“… Mains and lift stations move wastewater uphill to a lagoon about a half mile north of Woden, where tertiary treatment of the effluent occurs.” Read More >
