This standard applies to sewer manholes, catch basins, gate houses and pumping stations precast in
reinforced concrete and intended for use up to a maximum depth of 7 metres in sanitary sewer systems,
combined sewer systems, storm sewer systems and drinking water networks.
When the depth exceeds 7 metres, sewer manholes, catch basins, gate houses and pumping stations
shall have a design specifically addressing structural strength and leaktightness.
The structural analysis of sewer manholes, catch basins, gate houses and pumping stations shall be
conducted by the manufacturer based on their type of use and the analysis shall be approved by a
design engineer member of the Ordre des ingénieurs du Québec (OIQ).
NOTE — For requirements concerning the installation of sewer manholes, catch basins and gate houses,
referral to Standard BNQ 1809-300 (see Annex J) is recommended.
Cast iron frames and risers, manhole covers, grates, catch basins traps and safety platforms are not included
in the scope of this standard.
This document was developed to serve as a reference document for conformity evaluation activities
of specific products.
NOTE — Conformity evaluation is defined as the systematic examination of the extent to which a product
fulfils specified requirements.
