A review of the WSPs is presented in the Water System Review located in Volume 3
Appendix A.
Storage and Transmission System
The primary network in HRM supplying the urban core is divided into three operating
regions: West (Metro Halifax, Spryfield, Herring Cove), Central (Bedford and Sackville),
and East (Dartmouth, Cole Harbour, and Eastern Passage). The J.D. Kline WSP supplies
the West and Central regions, while the Lake Major WSP supplies the East region. The
service areas for the J.D. Kline and Lake Major WSPs are presented in Volume 1 Appendix
D, which contains the maps for Volume 1.
The three operating regions are further subdivided into a total of 67 pressure zones (21
in the West, 30 Central, 16 East). The pressure zones reflect the elevation differences
through the HRM. There are approximately 1,400 km of water mains ranging in
diameter from 50mm to 1500mm, some of which date back to the mid-nineteenth
century.
Halifax Water is currently developing a long-term plan to expand and upgrade the trunk
water transmission main system across the urban core to meet the demands of a
growing population, to enhance overall system security, and to strengthen the capacity
of the system to provide water under emergency conditions between the Pockwock
System and the Lake Major System. The details of the transmission main program are
presented in Volume 1 Appendix F of the IRP report.
A summary of the distribution systems is also presented in the Water System Review
located in Volume 3 Appendix A.
