Orenco Systems: Intermittent Sand Filter
Intermittent Sand Filters
Intermittent Sand Filters are an ideal advanced treatment solution where high
groundwater, poor soils, or other site constraints rule out conventional septic
systems. Tucked neatly underground, out of sight of the homeowner, pre-engineered
kits from Orenco Systems use high quality, reliable components. No more shopping
around, piecing together parts. Regulators appreciate the advanced level of
wastewater treatment from our sand filters, which typically produce BOD and
TSS of less than 5 mg/L. Contractors and installers appreciate the easy installation
and helpful video. And homeowners appreciate the low system maintenance and
low operating costs.
A 130-year-old technology, intermittent sand filters are approved in about
40 states, representing all climate zones, and in most of Canada. Modern intermittent
sand filters use pumps, liquid level sensors, and programmable controls to evenly
dose the sand media with septic tank effluent throughout the day. Orenco's engineers
assist with media specifications, tank sizing criteria, application rates, dosing
frequency, drainfield sizing, and maintenance requirements.
