Underground Overhaul Project Status Updates

Key items completed:

• CIPP lining activity has been completed. The last liner (13 in total) was completed, on schedule, December 4th and the sewer trunk was operational by the next day, December 5th. The full length of Zone 4, which comprised of approximately 827 meters of sewer, was lined for a grand total of 3,995 meter, for the project.
• Follow-up reinstatement has been ongoing with most re-paving and landscaping work completed. Should you notice any incomplete reinstatement items at your property or within your area, please rest assured that any residual landscaping and other related reinstatement work will be finished up by work crews when the finer weather and more ideal work conditions return next spring.

Key items completed:

• Lining work resumed on October 20th and by October 31st was completed over the entire length of Zone 3 (Ridgewood Drive to the Atlantic School of Theology (AST) area). There was approximately 943 meters lined over this period for a grand total of 3,168 meters (or 80%) of the total 3,995 meter length of the NWA sewer trunk section to be lined.
• The scheduled lining process will remain idle until approximately mid-November once the necessary lining infrastructure is in place from the AST pump station MH76A location through to the last manhole MH93 near the Balmoral pump station. Only 823 meters of the NWA sewer trunk sewer section remains to be lined.
• The rehabilitation of the 17 manholes required for access for CCTV (video) work and for the lining process is now 100% complete throughout Zones 1 through 4. The listing of the manhole access work completed includes:
  • 17 Completed: Zone 1: MH3, MH7, MH12 ,MH15, MH20, and MH24,  Zone 2: MH26, MH37, MH43 and MH43A, Zone 3: MH55A, MH59 and MH62A  Zone 4: MH76A, MH84, MH86A and MH93.
• The CCTV work being performed by EmPipe has been completed from Zone 1 through to the mid portion of Zone 4; this work is required to gather information on sewer pipe measurements and identification of service interconnections. In total, approximately 4,000 meters of the NWA sewer trunk has been videoed for lining reference to date. This equates to approximately 90% complete of this total task.
• The installation of the sewer lateral service interruption “crocks” to divert sewer flows during the lining process is ongoing in advance of lining into Zone 4. The crocks and connections previously installed in Zones 1 and 2 along the Quinpool Road through to Ridgewood Drive sections have been removed and the areas have been reinstated. This process will soon be underway in Zone 3 (Ridgewood Drive to the AST).
• The installed by-pass pumping lines (dual 18” diameter HDPE) required to divert flows around the NWA sewer trunk to allow for the CIPP lining in Zones 2 and 3 will soon cease to be required. This bypass system, along with the temporary large pump set-ups, will be removed beginning on or around November 6th and these areas reinstated.
• The CIPP liner fabrication is now underway for Zone 4.
• The required tree-trimming and arborist work as pre-approved by Halifax Municipality remains ongoing as required.
• All regulatory permitting required by Halifax Municipality Parks, Halifax Municipality Right of Way Services, CN and NSPI are now all in place. All project related traffic disruption notifications and work activity notices are being circulated as required and project signage being maintained in place.

The lining work resumed on September 11th and by September 22nd was completed over the entire length of Zone 2 and into a small section of Zone 3 (Coburg Road through to Ridgewood Drive areas). There was approximately 1,083 meters lined over this period for a grand total of 2,226 meters (or 56%) of the total 3,995 meter length of the NWA sewer trunk sewer section to be lined.
• The lining process as was previously scheduled will currently remain idle until approximately mid-October when the necessary lining infrastructure is in place at the Belmont on the Arm MH 59 location and surrounding areas.

• The CCTV work being performed by EmPipe has been completed from Zone 1 through to Zone 3; this work is required to gather information on sewer pipe measurements and identification of service interconnections. In total, approximately 3,750 meters of the NWA sewer trunk has been videoed for lining reference to date. This equates to approximately 85% of this total task.
• The installation of the sewer lateral service interruption “crocks” to divert sewer flows during the lining process is now ongoing in advance of lining into Zones 3 and 4. The crocks previously installed within Zones 1 and 2 from Quinpool Road through to the Ridgewood Drive section are currently in the process of being removed and these areas reinstated.
• The installation of by-pass pumping lines (dual 18” diameter HDPE) required to divert flows around the NWA sewer trunk to allow the CIPP lining in Zones 2  and 3 was successfully installed from South Street through to the AST.
• The CIPP liner fabrication is now underway for Zone 3.
• The required tree-trimming and arborist work as pre-approved by Halifax Municipality remains ongoing as required.
• All regulatory permitting required by Halifax Municipality Parks, Halifax Municipality Right of Way Services, CN and NSPI are now all in place. All project related traffic disruption notifications and work activity notices are being circulated as required and project signage being maintained in place.

Key items completed:
