DISPOSITIFS DE CONTRÔLE DU DÉBIT |
Committee recommendation
That Council approve that, until such time as new protocols are
finalized and approved by Council, staff be directed to permit connections to
the existing storm sewer system provided that a flow limiting orifice plate,
designed by an engineer to the satisfaction of the City, be installed at the
storm water outlet prior to connecting upstream storm sewers.
Recommandation DU Comité
Que le Conseil approuve que, jusqu’à
ce que de nouveaux protocoles soient finalisés et approuvés par le Conseil, le
personnel soit enjoint de permettre les raccordements au réseau d’égouts
pluviaux actuel pourvu qu’un diaphragme de limitation de débit, conçu par un
ingénieur à la satisfaction de la Ville, soit installé au point de rejet des
égout pluviaux avant le raccordement aux égouts pluviaux situés en amont.

REPORT RECOMMENDATIONS
That the Planning and Environment Committee recommend Council approve
that, until such time as new protocols are finalized and approved by Council,
staff be directed to permit connections to the existing storm sewer system
provided that a flow limiting orifice plate, designed by an engineer to the
satisfaction of the City, be installed at the storm water outlet prior to
connecting upstream storm sewers.
RECOMMANDATIONS DU RAPPORT
Que le Comité de l’urbanisme et de
l’environnement recommande au Conseil d’approuver que, jusqu’à ce que de
nouveaux protocoles soient finalisés et approuvés par le Conseil, le personnel
soit enjoint de permettre les raccordements au réseau d’égouts pluviaux actuel
pourvu qu’un diaphragme de limitation de débit, conçu par un ingénieur à la
satisfaction de la Ville, soit installé au point de rejet des égout pluviaux
avant le raccordement aux égouts pluviaux situés en amont.
BACKGROUND
Pursuant to Section
77 (12) of the Procedure By-law, Councillor Feltmate requested that the
following motion be placed on the Planning and Environment Committee Agenda:
WHEREAS staff were directed to develop and implement protocols by
January 31, 2010, that require a professional engineer to certify that all
required Inlet Control Devices are properly installed and inspected prior to
permitting a new storm sewer to connect to the City's existing storm sewer
system; and
WHEREAS the Commence Work Notification for all development proceeding
to construction since January 31, 2010, has been revised to address the
afore-mentioned Council motion for enforcement during construction; and
WHEREAS, the requirement that all required Inlet Control Devices be
properly installed and inspected prior to permitting a new storm sewer to
connect to the City's existing storm sewer system has created some challenges
for the construction industry; and
WHEREAS a flow limiting orifice plate installed at the storm water
outlet prior to connecting upstream storm sewers provides protection that is
greater than or equal to the protection provided in the approved storm sewer
system with the required Inlet Control Devices, and using a flow limiting
orifice plate meets the City's objectives and poses fewer challenges for the
construction industry;
THEREFORE BE IT RESOLVED THAT, until such time as new protocols are
finalized and approved by Council, staff be directed to permit connections to
the existing storm sewer system provided that a flow limiting orifice plate,
designed by an engineer to the satisfaction of the City, be installed at the
storm water outlet prior to connecting upstream storm sewers.
This motion seeks to modify the requirements set out in a previous resolution, which was approved by Planning and Environment Committee at its meeting of 13 October 2009, and approved by City Council at its meeting of 28 October 2009:
WHEREAS the City of Ottawa’s Design Guidelines has been shown to provide a high degree of protection against flooding during storm events, and
Environmental Services and Infrastructure Services staff were consulted on the motion and support it.
Planning and Growth Management
Comments
This revised approach will provide protection for the existing storm system that is in line with the level of protection achieved through the use of Inlet Control Devices.
This approach will address some practical concerns that have been raised by the construction industry. Planning and Growth Management supports this revised direction.

This item will be advertised in
the local daily newspapers as part of the Public Meeting Advertisement on the
Friday preceding the Planning and Environment Committee meeting.
RURAL IMPLICATIONS
There are no rural implications.
FINANCIAL IMPLICATIONS

There are no legal or risk
management implications to the adoption of the procedure provided for in this
