Absorbing Wells

Absorbing Well

Standard BNQ 3682-850
Structures for Absorbing Wells for Residential Use – Prefabricated structure - Size and physical properties

Waste water treatment relies on structures that demand a solid, effective and safe design. For that reason, the BNQ developed a series of standards governing septic tanks, holding tanks and absorbing wells. BNQ 3682-850 applies in particular to absorbing wells used for detached dwelling waste water treatment. It specifies the size and physical properties of the prefabricated structure for absorbing wells for residential use in concrete, fiberglass reinforced polyester or polyethylene.

Certification Offer

Certification Mark - Structures for Absorbing Wells for Residential UseFor a manufacturer of structures doing business in Québec, BNQ certification is an excellent calling card. The BNQ has therefore established a certification program to certify waste water treatment structures based on four documents, including BNQ protocol 3682-925. This protocol establishes procedural rules and marking requirements applicable to prefabricated septic tank certification in accordance with BNQ 3680-905, to prefabricated holding tanks in accordance with BNQ 3682-901 and to prefabricated absorbing well structures to BNQ 3682-850.

This certification program is accredited by the Standards Council of Canada.
