Town of Grand Bay-Westfield
The Town of Grand Bay-Westfield, with a current population of approximately 5000, is entirely serviced with potable water by individual private wells. Lot sizes throughout the Town range from less than 0.20 acre to several acres. The current minimum lot areas are 0.17 to 0.23 acre for lots serviced with sanitary sewer and 1to 3 acres for unserviced lots depending on the respective zones as defined by the Town's Zoning By-law. Given the topography of the local area and the predominantly shallow soil cover to fractured bed rock, the universal and effective treatment of sanitary wastewater is crucial to the preservation of
groundwater quality. The former Village of Grand Bay, in recognition of this fact, initiated a central sanitary wastewater collection and treatment system in the mid 1970's. Since that time the system has been extended as funding became avialable. Presently less than 50 percent of the entire Town of Grand Bay-Westfield is serviced by the wastewater system.
The completion of the wastewater system is considered essential in maintaining the status quo with regard to municipal potable water supply. Even so, many residents have experienced poor water quality due to contamination from sources such as septic tanks, road salt, and high mineral content. In addition, sustained residential growth in some areas may result in a gradual lowering of the water table, particularly in predominantly bed rock areas where recharge of groundwater reserves is limited.
The above issues and other related factors are crucial to long range planning for the protection and preservation of reliable and clean groundwater supplies, particularly if a partial or complete municipal water supply system is not within the long term planning horizon of the municipality. The provision of clean drinking water is a basic fundamental human need rather than an optional service and therefore the adoption of a long term strategy by municipal staff and council in this area requires due consideration of the potential long term ramifications for public health and community growth.
The required maximum day capacity for a municipal water system
the entire Town of Grand Bay-Westfield has been estimated at 1.2
gallons per day based on current population and projected growth over a
twenty year planning period. This estimated capacity includes peak user
demand and when combined with fire fighting demand based on current
standards requires a total water storage capacity of approximately 4
The total length of the pipe network required to service the entire
is approximately 63 km with pipe diameters ranging in size from 150 mm
to 300 mm. Largely due to the linear development pattern and low
density, the cost of the supply and distribution network is over 75% of
the total cost of the entire system including supply, treatment,
and storage. The extreme variation in topography from east to west
the community will require three pressure zones regulated by at least
The requirements for pumping and water treatment are dependent on the water supply source ultimately selected. Based on the preliminary findings of this study, three options for water supply appear to be feasible as follows:
1. Groundwater Supply
2. Surface Water Supply
A variation of the Loch Alva option is feasible by
constructing a transmission
main parallel to Route 177 and 7 to the existing City of Saint John raw
water lines from Spruce Lake. Based on a pumping and water treatment
similar to Loch
At this point, it is important to note that some or all of the
options described may require a conventional or modified water
plant to meet regulatory treatment requirements. This would increase
respective total construction cost
3. Regional Water System
In conclusion, there are currently at least three potentially feasible options for a water supply source for a municipal water system. The groundwater option is contingent on finding two or more high yield wells through an exploratory drilling program with suitable water quality. The suitability of all options is subject to Environmental Impact Assessment and the prospect for approval by various regulatory agencies will change as regulations are revised and the continuing development patterns adjacent to potential water sources continue to influence the perceived impacts.
