Bonita Pump Station Construction Update
The native erosion control grass mix to reduce erosion of soil in the vegetated corridor around the wetland is growing! Later this fall, native plants will be installed to replace the invasive plant species that were removed this summer.
Pump/Pipe Encasement and Yard Piping
Starting Monday and continuing through the week, the final pump concrete encasement will be poured. Expect to see a few concrete trucks during this activity. At the same time, water pipelines on site will be installed and encased in concrete. These on-site pipes will send water to the pump station from the Waluga Reservoir in Lake Oswego and will pump water to reservoirs throughout Tigard for distribution to homes and businesses.
The following week, electrical conduit ducts will be installed between the generator and the future pump station building. The generator pad will also be formed and poured and the building pad electrical conduits will be installed.
For the next several weeks, crews will be working on Saturdays between 9:00 a.m. and 5:00 p.m.
Thank you neighbors for your patience as construction progresses.
