Standard BNQ 3682-901 Prefabricated Sewage Holding Tanks for Residential Use – Dimensional and Physical Characteristics
Waste water treatment relies on structures designed to be solid, effective and safe. For that reason, the BNQ has developed a series of standards on septic tanks, holding tanks and absorbing wells. In particular, the BNQ 3682-901 standard specifies the dimensional and physical characteristics of prefabricated holding tanks for residential use made of concrete, fibreglass-reinforced polyester or polyethylene. The standard applies to prefabricated holding tanks for underground installation to hold sewage from a low-flush toilet or chemical toilet, and grey water from isolated residences.

Certification Offer
For a structure manufacturer conducting 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 the BNQ 3682-925 protocol. This protocol establishes the procedural rules and marking requirements applicable to the certification of prefabricated septic tanks to the requirements of BNQ 3680-905, prefabricated holding tanks to the requirements of BNQ 3682-901 and prefabricated structures for absorbing wells to the requirements of BNQ 3682-850.
This certification program is accredited by the Standards Council of Canada.
