• Low Maintenance: The non-biodegradable filter medium normally does not require cleaning or changing (expected life span is 20-30 years).

• Low energy: Small intermittent pump is the only energy requirement.

No noise:  The Waterloo Biofilter has no noisy air blowers or mixers.

• Recoverable: Easy to recover if the septic tank fails, unlike sand filters or conventional tile beds. 

• Various configurations: the versatility of the Biofilter® minimizes tree cutting and excavation: it will fit your requirements, not the opposite.

• Artic or Caribbean: Developed and operated with Canada's winter in mind makes Biofilter® applicable to New England.

• Small footprint: Effective treatment in an area 5-10 times smaller than that of sand, soil, or peat beds; and 10-50 times smaller with recirculation or deeper beds, especially useful for larger systems.

• Bedrock, clay, swamp, small lot: Our small Biofilter® and new disposal means can be placed virtually anywhere- making it a perfect application for seacoast regions or lakeside homes.

• No solids production: Our unique aerobic-anoxic trickle filter process produces no sludge to pump out.

• High hydraulic loading: The Biofilter® has no hydraulic limitations- will not plug or flood by infiltration caused by groundwater or leaky toilets, unlike sand, soil or peat.
