Lower Post, British Columbia, Canada
The Daylu Dena Council is an Indigenous First Nations community based in Lower Post, British Columbia, a remote location in the far northwest of the province, near the Yukon border. The Council constructed a new water treatment plant to ensure safe, reliable drinking water for the community, comprising a water treatment plant room building and the site works required to connect the facility to the existing groundwater wells and backwater inground disposal basin.
Access to clean, reliable drinking water is a fundamental need, and for a remote Indigenous community the operational resilience of the water treatment infrastructure is particularly important; there is no immediate backup if a poorly commissioned or poorly documented facility fails.
Dewick & Associates was engaged to deliver a comprehensive suite of handover documentation for the project, giving the Daylu Dena Council the records and frameworks they need to operate, commission and maintain the plant effectively.

The Daylu Dena Council is the governing authority for the Daylu Dena First Nations community in Lower Post, British Columbia. To provide safe, reliable drinking water, the Council constructed a new water treatment plant comprising a treatment building, associated site works, and connections to the existing groundwater wells and disposal basin.
For remote First Nations communities, dependable water infrastructure is essential, making thorough commissioning and accurate handover documentation critical to long-term operational resilience. Canadian guidance for First Nations water systems requires comprehensive commissioning, as-built documentation and operation and maintenance manuals to support ongoing compliance, safe operation and asset management.
Dewick & Associates was engaged to deliver a complete documentation package, including Building Handover Manuals for the architectural and structural works, integrated Mechanical, HVAC and Electrical O&M Manuals, and Mechanical and Electrical Commissioning Plans. These incorporated system descriptions, commissioning procedures, Inspection and Test Plans (ITPs), commissioning check sheets and final commissioning records, creating a single, accurate handover package to support both the community’s operators and future maintenance contractors.
Producing commissioning and handover documentation for a remote Canadian water treatment plant requires careful coordination across architectural, structural, mechanical, HVAC and electrical disciplines. Every system must be commissioned and documented accurately to support reliable plant operation, protect public health and satisfy recognised commissioning and documentation requirements for First Nations water infrastructure. With limited access to specialist technical support, the manuals also needed to be practical, clearly structured and easy for operators and service providers to follow in the field.
Dewick & Associates developed an integrated documentation suite covering every aspect of the facility. Building Handover Manuals documented the architectural and structural elements, while Mechanical, HVAC and Electrical O&M Manuals provided clear operating, servicing and maintenance procedures for installed systems.
Detailed Mechanical and Electrical Commissioning Plans established the framework for verifying system performance through system descriptions, commissioning procedures, ITPs and commissioning check sheets. Following completion of testing, the verified commissioning results were incorporated into the final Building Handover Manuals, producing a single, comprehensive record of the plant as designed, tested and handed over.
The Daylu Dena Council received a fully integrated set of Building Handover Manuals, O&M Manuals and Commissioning Plans that support the safe operation, maintenance and long-term management of its new water treatment plant. The completed documentation provides future operators and service providers with a reliable reference for maintaining system performance, helping to protect drinking water quality, support regulatory compliance and maximise the long-term value of this essential community infrastructure.
