| Details of Certification Program 3680-910 |
| |
| The Quebec Ministry
of Environment regulation Q-2, r.8 state that
beginning December 31 2005 wastewater treatment systems
used for isolated dwellings in the province of Quebec must
be certified according to the BNQ Standard NQ 3680-910
Wastewater Treatment - Stand-alone Wastewater Treatment
Systems for Isolated Dwellings.
A test site devoted to the certification program
was built in
2003. The certification process is explained in details in
the certification protocol NQ 3680-915
Wastewater Treatment - Stand-alone
Wastewater Treatment Systems for Isolated Dwellings -
certification protocol.

| Main Requirements of Standard NQ 3680-910
This Standard establishes the requirements for
material, design and construction, and performance testing
and evaluation of stand-alone wastewater treatment systems
used to treat wastewater from isolated dwellings. The
Standard includes a 6 month performance test similar to
the ANSI/NSF 40 Standard, plus a 6 month test to make sure
that the equipment will perform correctly during the four
seasons encountered in the average Canadian climate. There
are five types of treatment covered by the BNQ standard
and it is the only known standard with requirements
for coliform (Treatment Class III, IV, V).

| THE BNQ CERTIFICATION PROCESS
FOR STAND-ALONE WASTEWATER TREATMENT SYSTEMS |
| |
The certification process is not only an accreditation or
homologation based on a test result. The certification
process implies periodic quality control by the BNQ for
the certified products to assure the continuity of
compliance with the requirements of the Standard:
- The manufacturer makes a request for certification
and sends information requested by the BNQ.
- The BNQ verifies if the equipment to be certified
meets mechanical and electrical requirements of the
Standard.
- The testing according to Annex B, for every
manufacturer.
- The delivery of the certificate of conformity to
the Standard when all the requirements are meet.
- The verification twice a year of the production
process at the manufacturing plant.
- The annual visit of several installed treatment systems
for wastewater sampling and effluent analysis.
All the data related to the certification of a system
is kept confidential by the BNQ, even the names of the
clients during the certification process. The manufacturer
will receive the complete report for the certification
tests. When a client succeeds with the certification
process for its treatment system, the BNQ will publish the
name of the manufacturer and the model certified in the BNQ list
of certified products.
The certification process is detailed in the
certification protocol NQ
3680-915 available to everyone.
To avoid double testing, NSF and BNQ have signed an
agreement for mutual recognition of test results. This
simplifies certification to ANSI/NSF 40 for products
certified under NQ 3680-910 and those products already
certified ANSI/NSF 40 need less testing in order to comply
with NQ 3680-910. To get more details on this
certification program, please contact
Sophie Paré.

| TEST SITE DEVOTED TO THE CERTIFICATION
PROGRAM |
| |
| The certification process requires a test site
operated by an organisation registered to ISO 17025 and
not involved in the development of stand-alone wastewater
treatment systems to assure confidentiality and to avoid
conflicts of interest. The confidentiality of data shall
also be protected by restricted access to the test site.
The BNQ test facility is supplied by a continuous and
constant quality of domestic only wastewater, from a
vacuum pumped residential wastewater system. The BNQ test
site is in operation since the fall of 2003. The test site
allows for 8 treatment systems to be tested
simultaneously. The test site was modified in 2004 to
allow testing with temperature controlled wastewater if requested by
the manufacturer. Non temperature controlled wastewater is
also available for certification of treatment systems and
temperature varies annually between 5 and 15 oC.
Systems being tested are installed in the ground as
specified by the manufacturer, so there is little to see
at the site. The following photos show the BNQ test site, dosing equipment, etc.
