Description
The rivers surrounding the Island
of Montreal constitute an ecological
heritage of inestimable richness,
the envy of cities around the world.
They also offer the population an
immense potential for recreational
activities.
Since the start of modern wastewater
treatment in Montreal, water quality
along the riverfronts has gradually
improved and is now close to meeting
norms for swimming.
However, during heavy rainstorms,
overflow water from unitary sewer
collectors, faulty connections within
the separate wastewater networks and
poorly maintained septic systems are
sources of contamination which still
affect the quality of our water systems.
Wastewater adds a significant amount
of contaminants to our rivers, including
floating debris, harmful micro-organisms
(viruses, bacteria, etc.), suspended
particulate matter and industrial
wastewater (heavy metals, etc.). This
affects water quality in the river
and greatly limits the restoration
of active use of the waterways around
the island of Montreal. We must develop
additional measures to eliminate this
water pollution.
There are ways to eliminate discharge
during dry periods. For example, boroughs
could eliminate cross-connections
between storm water systems and the
sewage system and construct retention
basins for runoff caused by heavy
rains. Decision-makers must take action
now to reclaim the river for use by
the community, thereby improving water
quality - and quality of life.
In the ZIP Ville-Marie Committee action
plan, Montrealers indicated that the
waste water discharge problem is a
priority. Beginning in 1997, on the
initiative of the two metropolitan
ZIP Committees (Ville-Marie and Jacques-Cartier
Priority Intervention Zones), and
the Montreal Permanent Wastewater
Follow-up Committee, action has been
taken to eliminate the discharge of
non-treated wastewater.
Thanks to efforts by the Permanent
Wastewater Follow-up Committee and
a campaign to inform Montreal borough
decision-makers about the impacts
of wastewater outlets, several correctional
measures have been implemented.
In 2004, the City of Montreal established
the Water Fund to finance correctional
measures.
Eastern part of Montreal - 96th -
97th Avenues |
| |
• February 2005: 80% of work
completed
• August 2005: Completion of
work - Total cost of improvements:
$14 million |
Perras Collector (Beausoleil Street) |
| |
• The City of Montreal will
spend $5.5 million in 2005 for the
construction of a wastewater network
in the La Roussellière Sector - 52nd
Avenue |
| |
• A complicated problem because
this sewer is in federal property
(the Montreal Port) and leased to
the City of Montreal.
• the Permanent Committee and
the City of Montreal are currently
addressing the situation. |
| |
• The borough of Rivière-des-Praires-Pointe-aux-Trembles-Montréal
Est has issued a Call-for-Bids to
detect faulty connections in the La
Roussellière and 80th Avenue sectors. |
Bois de Saraguay - Notre-Dame des
Anges |
| |
• Problem identified. The Toupin
collector has several cross-connections
problems. Diagnostics are being made
under the direction of the Saint-Laurent
borough. |
| |
• Two religious properties,
Hermitage Ste-Croix and Solitude Notre-Dame,
are not connected to the sewer system.
• Presence of septic systems
located in the floodplain.
• To correct these problems,
sewer lines must be laid in two streets.
In addition, a pumping station must
be added to pump wastewater up to
the Pierrefonds main network.
• Estimated costs --- $2.3 million |
| |
• Problem has been located under
the bridge - File being considered
by the borough.
• The 45 houses of the Île Madore
sector have finally been connected
to the sewer system. File closed. |
