Water Treatment Plant Construction Update

All 250 auger cast piles in the clearwell and 78 piles in the ballasted flocculation are now complete! The smaller drill rig is now being demobilized and will be removed from site next week. The large drill rig will remain on site to drill piles for other foundations.

Demolition of the two existing lagoons on the northeast of the site is underway. A hydraulic hammer will break up the remaining base of the lime building next week. Starting Monday, the stockpiled concrete will be crushed on-site for later reuse. Crushing will occur after 8 a.m. toward the middle of the site and with the fan facing inward to reduce noise. Crushing the material for later reuse on site reduces truck traffic in the neighborhood by over 1,300 one way trips.

Water Treatment Plant Construction Update

Drilling and installation of the auger cast piles continues in the clearwell and finished water pump station. Early next week, a second drill rig will arrive and begin installing auger cast piles for the base of the ballasted flocculation building.

In mid January, the contractor will begin demolishing the lime building and preparing two of the existing lagoons on the northeast of the site for demolition. This will involve breaking up the concrete, then stockpiling and crushing it on-site for later reuse. Concrete crushing is scheduled to occur in early February.

During the demolition work, there is the potential for increased noise during work hours, depending on neighbor’s locations or personal sensitivities.

Generally over the next month, work hours will be Monday to Friday from 7:00 a.m. to 5:00 p.m. and Saturdays, from 9:00 a.m. to 5:00 p.m.

The table below describes what activities are happening on-site over the next few weeks, the purpose and estimated duration of work.

River Intake Construction Update

Updated January 2, 2014

Work is continuing on forming the pump station walls at the river intake construction site in Gladstone, with the first 15 feet of walls now formed with concrete.

The second level wall forms are now being installed above the first level concrete walls. A large concrete pour is scheduled to occur around these forms on January 6, which should take about one day to complete. After the pour, the concrete will set in place for a few days before the wall forms are removed from the second level and reinstalled above the newly poured concrete. Reinforced bar will also be added to support the walls.

During the concrete pour, neighbors can expect some noise and an increase in truck traffic as 12-15 concrete trucks arrive at the site. Generally, during the next three weeks, work hours will be 7:00 a.m. to 6:00 p.m. Monday through Saturday. No work will occur on New Year’s Day.

We wish everyone a safe and happy holiday season.
