OSCAR-II Large Soil Absorption System Design Manual-Idaho
Conventional Idaho wastewater treatment and dispersal systems can’t do the job? OSCAR Onsite’s wide variety of reliable and affordable alternative products and systems may be just the ticket to keep your wastewater management project moving forward. Wastewater and water reclamation system contractors throughout the state depend on our experienced and knowledgeable pros to help identify and place alternative treatment and dispersal units and technologies.
The Orchard Combat Training Center’s (OCTC) shower facility is an example of how a single duplex pump station can facilitate a high daily flow. Although the OCTC facility has a design flow of 2200 gallons per day, it is a good example of how a Large system is laid out. The case study of this facility can be found here. Lowridge Onsite Technologies, LLC provides design assistance including DWG or pdf drawings, material specifications and submittals, and field installation training.
Septic systems with design flows over 2500 gallons per day (Large Soil Absorption Systems) have a different set of regulations than for design flows under 2500 gallons per day. The OSCAR-II system is no different, so we’ve developed a design manual for larger systems to meet Idaho regulations. OSCAR Onsite also provides design assistance including DWG or PDF drawings, material specifications and submittals, and field installation training for all our Idaho wastewater treatment and dispersal products and systems.
One unique design feature of the Larger OSCAR-II systems is that it’s operated by a small 1/2 hp, 110 volt pump. A duplex set of pumps and one headworks can operate a system design flow of 5600 gallons per day, and if a larger flow is needed, an additional duplex pumping station can be installed in the same or different pump tank.
The OSCAR-II system is another of our high-quality Idaho wastewater treatment and dispersal products, developed and approved for use with as little as 12” of soil above the restrictive layer or water table. An at-grade onsite sewage treatment and dispersal component dosed with septic tank effluent, the OSCAR-II is comprised of a 12” layer of medium sand media and a series of custom manufactured Netafim Bioline drip tubing coils. The sand media is placed on a prepared soil surface with OSCAR coils placed on top and covered with another 6” of sand media. No other cover material is needed.
The OSCAR-II system is comprised of a single compartment septic tank, a discharge tank, a reverse flush headworks, and the OSCAR unit. The septic and discharge tank must be on the approved list (TGM Section 5.2 Approved Septic Tanks) and IDAPA 58.01.03.007.07. The OSCAR unit can be designed with two coil options: OS-50 (5’ diameter coil rated at 50 GPD) and OS-100 (7’ diameter coil rated at 100 GPD).
