Standard BNQ 3680-905 Prefabricated Septic 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 governing septic tanks, holding tanks and absorbing wells. In particular, the BNQ 3680-905 standard specifies the dimensional and physical characteristics of prefabricated septic tanks in concrete, fiber-glass reinforced polyester or polyethylene for residential use. It applies to prefabricated septic tanks intended for underground installation to store waste water, including household waste water prior to its conveyance to a purifying element, leaching field or waste water treatment system.
