The LOS statements and targets have some limitations reflecting in part uncertainty
about future regulation and the emerging nature of certain LOS e.g. asset renewal. The
IRP development described in Section 5, created 14 performance objectives tied back to
the existing LOS where possible. New LOS will however be required in other cases.
Halifax Water should review the existing LOS and targets and address the need to
update and expand the LOS. Specific recommendations are presented in Section 7 in
support of the IRP Implementation Plan.
3.4 HALIFAX WATER INFRASTRUCTURE
HRM’s topography, geography, current land use and history of development strongly
influence the nature of current water, wastewater and stormwater infrastructure. The
topography requires considerable water pressure management and wastewater
pumping due to the hills and plateaus, which define the geographic features within
HRM. The Halifax Peninsula together with the area in Dartmouth on the harbour side of
the Circumferential Highway forms the central part of the urban core within HRM. The
surrounding urban area of HRM is built around the outer harbour, Bedford Basin and
extending up the Sackville River Valley.
The large geographic reach of HRM and the diverse community size ranging from large
urban areas such as Halifax and Dartmouth to small communities such as Middle
Musquodoboit has resulted in a serviced urban core as well as independent services for
local areas. This has yielded a large number of small water and wastewater facilities
