Orenco^® UV Disinfection Units are designed for residential applications after advanced secondary treatment (10 mg/L or less for CBOD₅ and TSS) when disinfection is required before dispersal. They require installation inside a pump basin, gravity discharge basin, or a separate tank following an advanced secondary treatment system. The power ballast, current sensor, and controls are housed externally, to protect electronic components from environmental damage.

Orenco^® Flow Meters are used to measure cumulative flow through a transport line. They are typically used in applications where permits require exact measurement of flows, such as to a drainfield.

• 5/8-inch, 3/4-inch, 1-inch, 1-1/2-inch, and 2-inch (16-mm, 19-mm, 25-mm, 38-mm, 50-mm) models available
• Male threaded connection standard for 5/8-inch, 3/4-inch, and 1-inch (16-mm, 19-mm, and 25-mm) models
• Unions and slip connections available on 5/8-inch, 3/4-inch, and 1-inch (16-mm, 19-mm, and 25-mm) models
• Female threaded connection for 1-1/2-inch and 2-inch (38-mm, 50- mm) models
• Telemetry-equipped flow meters available by special order

Orenco^® Hydrosplitters are used to provide equal doses of screened effluent to multiple laterals or zones in gravity drainfields, regardless of the length of the laterals used in the drainfield. A dose pump is used to transport effluent to the hydrosplitter, which then doses all of the drainfield laterals by gravity.

Each Hydrosplitter is built to the specific needs of a particular drainfield. For information on ordering a Hydrosplitter for your project, call Orenco.

• Works with pump or siphon discharge to hydrosplitter
• Schedule 40 PVC construction
• 1/2-inch to 4-inch NPS (15-mm to 100-mm DN) sizes available for fittings, unions, and flow controllers
• 1/2-inch to 2-inch NPS (15-mm to 50-mm DN) sizes available for flexible outlet hose
• Flow Control Disc orifices sized in 1/64-inch (0.396-mm) increments

Orenco^® Carbon Filters are passive ventilation filters used to reduce the odor of sewage gases in systems that ventilate using passive airflow. They are easy to attach to a vent pipe. Carbon filters use activated impregnated carbon in replaceable packages. The cap is removable to allow replacement of the carbon package.

• 3-inch, 4-inch, and 6-inch NPS diameters (80-mm, 100-mm and 150-mm DN)
• Slip-fit
• UV-resistant
• ABS and PVC construction (CF3 and CF4)
• Fiberglass and PVC construction (CF6 )
• Polyethylene screen plate
• Replaceable carbon packages

The AMSSI Siphon Sitter I Kit uses a signal float switch installed inside of a dosing siphon to record dosing events.

• AMDDC Digital Dose Counter (3.2-VDC long-life lithium battery included)

• Float switch collar
• Dosing siphons in 2-inch, 3-inch, 4-inch, 6-inch, and 8-inch (50-mm, 80-mm, 100-mm, 150-mm, and 200-mm)
• Signal-rated float switch ordered separately

Orenco^® Flow Control Discs and Flow Control Assemblies are used in pressurized distribution systems to equalize flow in laterals of varying elevations and lengths. The size of the orifice in the flow control assembly is based on multiple factors.

Orenco^® Distributing Valve Assemblies are used to dose filtered effluent to multiple-zone pressure distribution systems including drainfields, textile filters, and sand filters. They are automatically operated by mechanical means — with a combination of pressure and flow — to sequentially redirect the pump’s flow to multiple zones or cells.

Custom-built enclosures are available for Orenco Distributing Valve Assemblies. Call Orenco for details.
