Updates on LOTT construction projects
Biological Process Improvements
LOTT is planning a project to make major improvements to the biological process at the Budd Inlet Treatment Plant. The project involves replacing aging equipment with new technology to reduce energy use, increase process reliability, and provide greater control and flexibility in the biologic process. The project will occur in the northeast area of the plant and will require removing some vegetation and trees along the plant perimeter and adding approximately 5,000 square feet of impervious surface. Landscaping will be planted after the project is completed. As part of the State Environmental Policy Act (SEPA) process, LOTT has completed an environmental evaluation and issued a Determination of Nonsignificance stating the project will not have a probable significant adverse impact on the environment. Project construction is expected to begin by late 2020 and will take several years to complete.
Washington Street Property Improvements
LOTT is preparing to demolish the building at 516 Washington Street NE. Work will begin in early 2020 and be completed that summer. The existing structure will be leveled to the concrete slab. The site will then be fenced and paved, and stormwater treatment will be added. The site is 62,300 square feet and the structure to be demolished is 42,700 square feet. Currently the site provides parking for LOTT contractors and food bank volunteers. After project completion, the site will be used primarily for contractor staging for Budd Inlet Treatment Plant projects. Eventually, the site will be used for expansion of treatment processes associated with the treatment plant. As part of the State Environmental Policy Act (SEPA) process, LOTT has completed an environmental evaluation and issued a Determination of Nonsignificance stating the project will not have a probable significant adverse impact on the environment.
Disinfection System Upgrades
In early 2020, LOTT completed a project at the Budd Inlet Treatment plant to upgrade the ultraviolet (UV) light disinfection system. UV light is used in the final stage of wastewater treatment to disinfect the water prior to discharge into Budd Inlet. UV light works to render bacteria harmless. The upgraded system provides increased treatment capacity, improved energy efficiency, and easier maintenance.
