Final Update

The water treatment plant has been operating since late January providing highly filtered water to the community. The plant access road has been paved out and the security fence in place. Work continues to fine tune the filters operation, complete a fire booster pump station for the City’s high zone distribution, installing a potassium permanganate feed system, and general close out of the punch list and paper work.

January Update

The big news at the Water Treatment Facility is that, with the start of a continuous five (5) day Performance Test, filtered water was placed into the City’s water distribution system. The city’s mayor pushed the button to start the filters producing a million gallons of water a day. Also notable, the City moved their water analysis laboratory into the new building.

The new 5 million gallon reservoir passed a water tightness test. And a new 16″ ductile iron pipe was connected from the reservoir to the existing water system to allow the transfer from the old reservoir. The old reservoir was not designed to withstand an earthquake and will be demolished sometime in March.

Note that the paved trail along the east side of Rainier Street from Discovery Road to the intersection of Howard Street and 20th Street remains open.

 

December Update

At the water treatment facility, the filtration equipment has passed a functional test and is ready to go on line following final approval by the engineers and the State Department of Health. City operators and maintenance personnel continue training and hands on operation of the various pieces of equipment, such as pumps, tanks, valve operation, instruments, analyzers, programming and controls. It now appears that filtered water will be produced and put into the City’s water distribution system in early December. Outside the building, the curbs, paving, and landscaping are well underway. At the reservoir site, yard piping continues to be placed connection the new 5 million gallon reservoir to the water system and isolating the old reservoir for demolition.

Note that the paved trail along the east side of Rainier Street from Discovery Road to the intersection of Howard Street and 20th Street remains open. The trail access at Discovery Road has been moved slightly to the north and signed to avoid the new roadway construction on Howard Street. From 15th Street north, an orange construction fence is in place as a safety barrier to separate construction traffic from the adjacent trail.

 

November Update

At the water treatment facility, the equipment supplier is doing checks on the filtration system and commissioning equipment including process, blow down, and chemical cleaning systems. At the same time, the City operators and maintenance personnel are being trained on the various pieces of equipment, such as pumps, tanks, valve operation, instruments, analyzers, programming and controls for a planned start-up in early November. Outside, the curbs and paving, as well as plans for landscaping, are underway. At the reservoir site, the high zone standpipe tie-in is in place, and yard piping will be placed to connect the new reservoir to the system.

September 26th Update

The water treatment building is fully closed in and weatherized. Focus at the facility (WTF) continues on conditioning the membrane filters and preparing auxiliary support equipment. Good progress has been made on air, water and chemical piping as well as electrical and control wiring for the process equipment. The equipment supplier, Evoqua, is on site starting pumps, compressors, blowers and operating valves, as well as checking instrumentation.

In late October the filters, compressed air, air scour, chemical cleaning, neutralization, and control systems will all be brought together for system start-up. It will take several weeks to adjust the process system, train operators, and receive the engineer’s and the State’s approval prior to producing water that can go into the City’s distribution system.

May 9th Update

The photographs above show concrete being placed on the second quarter of the 5MG Reservoir roof and a SST outlet diffuser pipe next to it.

The PUD is bringing in the electrical power feed for the Water Treatment Facility, along 20th Street.

The contractor is also doing roof work on the Water Treatment Facility, as well as some interior painting and setting one of the equalization vaults.

April Weekly Update

The site contractor has the roof joists set on the Water Treatment Facility building and will start the roof decking next week.

At the new 5MG Reservoir, the subcontractor has completed shoring and forming for the first half of the roof. Next week they will start rebar placement for the 10″ thick roof section. And early next week a specialty contractor will be on site to tension the vertical wall tendons.

The utilities contractor is working on running in the new 10″ ductile iron water main along Rainier Street from the treatment plant.

March Weekly Update

Workers are moving quickly to install the steel shoring 40′ high that will support the forms for the water reservoir roof slab. Next week concrete will be placed in wall 11, the final wall for the reservoir, closing up the structure and access through a stairway.

At the water treatment facility, the masons have completed the reinforced block walls and 80′ roof joists are being set. And one of the fiberglass tanks has been set by crane within the building space. Pre-purchased filter equipment has arrived, with the exception of the complex filter array skids due to arrive late in April.
