CRD proposes design change to region's wastewater treatment plant
CITIFIED.CA STAFF
Published February 20, 2018
The Capital Regional District has proposed a design revision to the McLoughlin Point Wastewater Treatment Plant now in the
early stages of construction along the entrance to Victoria’s Inner Harbour.
Described as “a more cohesive architectural expression” by project architect HDR | CEI, the updated design will lessen the plant’s visual impact while streamlining and refining its earlier architectural theme approved in February of 2017.
The most notable change, according to documents presented to the Township of Esquimalt, will result in the reduction of the plant’s massing through the removal of a Dissolved Air Floatation (DAF) unit from the southwestern portion of the complex.
The need for a large DAF unit was nixed through a decision to pursue an alternative sewage treatment technology that utilizes a duo of Moving Bed Biofilm Reactor cells in lieu of Biological Aerated Filter cells. In short, the change permits a smaller treatment facility to arrive at the same result.
As part of the design changes the second floor of the Operations and Maintenance (O&M) building, situated along the plant’s eastern frontage, will increase by over one metre. The change is described as beneficial to the plant’s day-to-day operations and will permit easier access for emergency vehicles.

A number of additional changes will expand the plant’s green roof to the northeast to make up for a loss in other areas, translucent panels along the east elevation will be removed in favour of a placement on the odour control room and colours of several exterior panels will be changed. In addition to the green roof extension, bicycle parking and a protected shelter have been added below the roof line.
Proposed changes will go before Esquimalt council for final approval on Feburary 26th. The changes do not affect the current stage of the plant’s construction.
The project is being built by Harbour Resource Partners (HRP), a consortium of firms that include AECOM Canada, Graham Infrastructure, HRD | CEI, SUEZ, Graham Capital and Michels Canada. HRP includes "top-tier global expertise in wastewater treatment plant financing, design, construction and operations coupled with local knowledge and experience gained on past Capital Regional District projects," according to a statement from the District.
With work underway since mid-2017, the nearly $800 million project's completion is estimated for the fall of 2020. C
