Essential Deficiency Repairs Get Underway at Halifax Wastewater Treatment Facility
(Thursday, March 4, 2010) - Commencing Friday, March 5th the Halifax Wastewater Treatment Facility (WWTF) will temporarily stop receiving flows to allow the contractor, D&D WaterSolutions Inc., to rectify deficiencies identified prior to the WWTF malfunction on January 14, 2009. The correction of these deficiencies is not related to the malfunction, but is essential to the long term operation of the facility.
This work is being undertaken at the contractor’s cost and will not delay the full restoration of the Halifax WWTF, scheduled for completion this spring.
During this shutdown, scheduled to take 1 week, all flows will be diverted from the Halifax WWTF and discharged through the Combined Sewer Overflow [CSO] chambers along the waterfront.
The items being modified are:
·The installation of a baffle system in the wet well to allow for a more even distribution of wastewater flows to the raw water pumps
·The installation of an auto-lube system for the main/coarse screen. This will allow for a more constant lubrication of the screen mechanism, provide better operation and prolonged operational life for the system
·Conversion of the coarse screen screw auger conveyor to a belt conveyor. This will allow for more efficient, reliable handling of coarse screened material.
With the completion of these items, dry weather flows will once again be diverted to the Halifax WWTF, debris and floatables removed via the coarse and fine screening system, and then discharged through the facility’s existing outfall pipe which extends approximately one kilometre into Halifax Harbour.
