Cost Estimates, Environmental Benefits and Sites for Five Core Area Wastewater Treatment Options Released Today

Dec 04, 2015

Victoria, BC– Today, the CRD released a report with new information relating to the Core Area wastewater treatment project. The report contains a technical report by the project’s engineering consultants, Urban Systems and Carollo Associates, outlining details of the five Core Area option sets and the estimated capital and operating costs. Public input and feedback gathered through the Eastside and Westside Select Committees’ public engagement processes was a critical factor in deciding which sites were chosen for more detailed technical and financial analysis. Also released today was a series of site maps for each of the option sets and preliminary estimates of average projected costs for households in the Core Area municipalities (Colwood, Esquimalt, Langford, Oak Bay, Saanich, Victoria, View Royal) and project costs for the Songhees and Esquimalt Nations.

The report will be presented to the Core Area Liquid Waste Management Committee (CALWMC) for consideration at the December 9 meeting, and will form the basis for public consultation launching in December and running until late January. All new information contained in the report is available in the background materials appended to this release.

Cost Estimates:

The estimated costs provided in the engineering consultant’s technical report were further assessed by CRD staff to apportion capital and operating costs to each of the Core Area participants, along with estimated annual costs per household. Apportionment of costs was conducted on the principle of design capacity benefit, allocating costs to those participants making use of each respective system element based on a percentage of flow. For example, for Option 1 A and B, a centralized liquid and solids treatment facility, all Core Area participants contribute to the land, liquid and solids treatment and reuse costs based on the overall distribution of design flows, but each participant may have different costs related to conveyancing, depending on whether new trunk mains or pump stations are needed to direct their flows to the facility. Please see Appendix A for a breakdown of the estimated household costs for each municipality.

The executive summary of the engineering consultant’s technical report notes that cost estimates for the five option sets differ from previous liquid waste management plans because the proposed option sets reflect a different suite of conditions and factors. Some of the factors include different site locations that were brought forward by the municipalities and tested for public acceptability, different cost estimate contingencies and a different planning horizon for various system components. Each of the different options will require different negotiations with funders. Please see Appendix A for a profile of each of the option sets provided by the engineering consultants.

Sites:

The identification and release of feasible sites by municipalities, followed by public engagement led by the Eastside and Westside Select Committees, has produced a number of prospective sites from municipalities and private land owners that have allowed their sites to be disclosed. Maps of the prospective site locations have been released where possible and some locations remain as bubbles or nodes on the maps where the CRD continues discussions with property owners. See Appendices C though F for a map of each of the potential site locations for each option set.

After consideration at the Core Area Liquid Waste Management Committee meeting on December 9, the next phase of public consultation will begin offering opportunities to learn about the option sets and methods to give feedback to the CALWMC.

The municipalities of Victoria, Saanich, Oak Bay, Esquimalt, View Royal, Colwood and Langford and the Esquimalt Nation and Songhees Nation collectively are participants of the Core Area Liquid Waste Management Service which is managed and operated by the CRD in accordance with the CALWMP. The Province has confirmed that the CRD is responsible for implementing secondary wastewater treatment in the core area within timelines prescribed in the CALWMP.
