Lake Babine Nation - Tachet Community Wastewater System

The Lake Babine Nation Tachet Community Wastewater System project involves the construction and commissioning of a new wastewater treatment facility located at Babine I.R. No. 25 in Tachet, British Columbia. Managed by Associated Engineering (B.C.) Ltd., the scope of work includes the development of a treatment facility featuring two aerated treatment lagoons, a polishing cell, control structures, aeration systems, chemical addition, and ultraviolet disinfection. The project also encompasses the construction of sanitary piping, a lift station, and wastewater mains. Key technical components include a complex process control narrative for automation and SCADA systems, as well as specialized equipment agreements for the lagoon aeration and UV disinfection systems, which are subject to novation to become subcontracts under the selected General Contractor. The contract is structured as a Unit and Lump Sum Price agreement, with an estimated project completion date of October 2027. While the total contract value is not fully defined due to pending unit price quotes for civil and mechanical works, stipulated sums for specialized components—including the chemical feed system, aeration system, and UV disinfection—total approximately $2,211,000. Procurement and evaluation for specific equipment, such as the chemical feed system, are based on a 100-point scale considering price, technical compliance, maintenance requirements, and local support. Due to the high archaeological potential of the site, the project mandates strict adherence to an Archaeological Chance Find Procedure and requires an Archaeological Impact Assessment prior to ground-altering activities. Compliance with various standards, including the British Columbia Building Code and Canadian Electrical Code, is mandatory, and the project requires rigorous commissioning through functional performance testing and system verification.
