Sooke Wastewater Treatment Facility Sooke Council decided that the only method the District could use to determine an actual cost for a new sewer system was to proceed with a Design/Build Proposal call. The District has finalized the Request for Expression of Interest process, selected three preferred proponents and started the Request For Proposal process. The final proposals, which will contain detailed design and final costs, are due the end of July. It is expected that the proposals will produce a maximum project cost of approximately $15,000,000. The challenges to Proponents are to find affordable wastewater solutions that will result in a maximum annual cost to the average homeowner of $650. The other challenge is to discharge the effluent near environmentally sensitive coastal areas.
