There are three main water supply areas around the
- Dumaresq Lake well field
- Sydney River water supply
- Grand Lake water supply.
Sydney, Whitney Pier, Ashby and Hardwood Hill (Supply Area 1,
Figure 2.4) are currently supplied by an aquifer-fed well field
located near Dumaresq Lake, ap-proximately 5 kilometres along the
Louisburg Highway from Highway 125. The calculated safe-yield of
this water supply is 6 million gallons per day (gpd), although the
Municipality only allows the removal of 3.8 million gpd to prevent
the draw-down of wells in the surrounding area. Water from this
well-field is piped approximately 3 kilometres to a treatment facility
near the old reservoir, where the water is treated before being
piped into the communities.
The Sydney River water supply services to the communities of Coxheath
and Sydney River, as well as providing the SYSCO property with process
water via a 24” supply line. The supply line to SYSCO was
designed to carry 4-5 million gpd, although since the closure of
the mill, the demand for water at SYSCO has been minimal. Complicating
matters is the fact that this 24” line to SYSCO also supplies
drinking water to approximately 100 to 125 commercial and residential
users located in Sydney and Sydney River. These customers are billed
monthly for their water consumption by SYSCO.
The number of customers using this system may be as high as 200
due to illegal feeds tapped into the line. In order to ensure the
water quality provided to these customers, the Sydney River pumping
station currently pumps 2.5 million gpd to the SYSCO site, most
of which is directly discharged into the harbour. This volume of
pumping is necessary to ensure that the water in the pipe does not
stagnate, thereby allowing the growth of bacteria.
CBRM is in the process of building new supply lines to water customers
currently feeding off the SYSCO line. In the future, their needs
will be provided by the Du-maresq Lake well field. All users should
be transferred off the SYSCO line by 2005. At this point, CBRM would
like to de-activate the Sydney River as a municipal water supply,
because the quality of water from this surface supply will be hard
to protect as development continues in the future.
The Grand Lake supply is the old water supply for SYSCO, although
the pipeline itself has been derelict for a number of years. Given
the relatively low level of development within the Grand Lake watershed,
CBRM is evaluating the potential of this area as a future potable
water source, which would allow the elimination of the Sydney River
water supply. Grand Lake is partially protected, as the Province
and CBRM own the majority of the land surrounding the lake (although
the up-stream drainage basin is not protected).
It is proposed that in the future, Grand Lake could supply the
Whitney Pier area. The proposed development of the Grand Lake water
supply would include a treatment facility in Whitney Pier and a
transmission line that would pass within several thousand feet of
the former SYSCO property. A branch from the transmission line (before
treatment) could potentially supply the SYSCO site with process
water, (depending upon volumes required), and any potable water
demand could be supplied from the treated water supply.
Regardless of CBRM’s decision on their water supplies and
distribution systems, the 24” line from Sydney River does
not need to be removed. The line, pumping station, and treatment
facilities are all owned and operated by SYSCO. While in the near
future CBRM will not have a need for this system from a residential
supply perspective, its value as a supply of industrial process
water is significant.
Routing a potable water source to new uses on the SYSCO site is
possible, whether Whitney Pier is supplied from Grand Lake or CBRM’s
well field. The estimated cost to install a pumping station and
intake at Grand Lake, as well as the transmission and treatment
system for approximately 1 million gpd, is $6-8 million. From start
to finish, once funding commitments are in place, construction would
take approximately 2.5 years.
