Testing of the new pumps at the RIPS begins!
Gladstone Pipeline and River Intake Construction Update
This update includes construction work in the following areas:
- River Intake Pump Station (RIPS) - testing of the new pumps begins!
- Meldrum Bar Park pipeline work - work continues on the connection near the river
- Microtunnel at Jensen Road pathway - excavation of the work pit almost complete
River Intake Pump Station (RIPS) - testing of the new pumps begins!
Early next week, the large red crane will be removed from the site. During this time, there will be several large trucks accessing the RIPS site from Portland Ave. The new pedestrian gate and fence will be installed over the next month.
Startup for pump testing began this week with Water Treatment Plant staff training on the new pumps. Operational testing of the new pumps will continue over the next few weeks, before the new RIPS is commissioned and pumping water to the existing treatment plant in West Linn!
In summer, the existing intake will be demolished. Once this is complete, landscaping will be installed.
Meldrum Bar Park pipeline work - work continues on the connection near the river
Last week, crews started working closer to the river, to make the connection with the newly installed pipe under the river. Crews are currently working at night in this area. Once this is complete early next week, crews will relocate back to near the contractor’s equipment staging area, and continue laying pipe on Meldrum Bar Park Road and through the ballfield parking lot. This work will be done during the day.
In mid-February, the ballfield parking lot will be temporarily closed. During this time, the lot will be used as an equipment storage and work area for construction of the pipeline through the parking lot.
Access to the park and boat ramp will remain open during regular park hours. Please watch for flaggers in the work areas—single lane closures are in place during construction in the park. Neighbors and park users can expect to see and hear excavators, loaders, pipe, steel plates, gravel and dump trucks.
Microtunnel at Jensen Road pathway – excavation of the work pit almost complete
Crews are almost complete with excavating and installing steel piles to support the microtunnel shaft (work pit) at the Jensen Road pathway near River Road.
Next week, crews will pour a temporary floor in the base of the shaft and set up the microtunneling equipment. The machine will then bore a tunnel under River Road and McLoughlin Boulevard, working east to Exeter Street. Large storage tanks to help separate the dirt and materials removed during microtunneling will be set up at the site and along the side of River Road, near Jensen Road.
Work hours are 7 a.m. – 6 p.m., Monday to Friday, and Saturdays, 9 a.m. – 6 p.m.
To maintain safety, there will be a single lane closure on River Road at the Jensen Road pathway during the microtunnel work. Two lanes of traffic will be maintained. The Jensen Road pathway is also closed to pedestrians during construction. Please use Meldrum Bar Park Road to access the park.
Neighbors can expect to see and hear excavators, a hydraulic crane, trucks, a separation tank for the materials removal and a generator. During work hours, there may also be an increase in noise, truck traffic and vibration depending on neighbors’ locations.
