BC Hydro is planning a significant amount of work for the HLK Spillway Gates Reliability Upgrade Project this year, and consequently the site will be very active.
BC Hydro is currently refurbishing Low-Level Outlet Gate three. The refurbishment process takes approximately three months and entails removing, inspecting and either replacing or refurbishing all of the parts; removing the existing seals; inspecting all existing welds; recoating the gate; installing the new seals; and inspecting and repairing the gate guides and other supporting equipment. In March, once work is complete, low-level outlet gate three will be reinstalled. The gate is then tested before it is returned to operation.
Following the reinstallation of Low-Level Outlet Gate three, Low-Level Outlet Gate two will be removed from the dam. Gate two will be transported to the warehouse at the north end of the facility where it will undergo the refurbishment, reinstallation and testing process.
Economic Benefits for the Local Community
This project brings significant benefits to the local community. An estimated $25,000 per month is spent locally in support of the work on this project, including the purchase of local project supplies and services whenever possible. This includes machining works and the fabrication of tools, office supplies, accommodations, equipment rentals, safety and environmental protection equipment and services. In addition, many of the workers on site have been hired locally.
Additional Planned Work
In addition to this project work, we will also be conducting preventative maintenance work on two of the Low-Level Outlet Gates. This work, which includes mechanical, electrical and civil inspections, ensures that we are able to identify and correct any potential issues in a timely manner.
Road Closure Reminder
I would like to remind you that the road over the dam has been temporarily closed until May 1, 2012 because it runs through our project work site area and we must ensure the safety of employees, contractors and the public during the duration on this project. Access to the navigational lock will remain open through the south entrance. We thank you for continued support as this significant infrastructure upgrade work is completed.
