Week 46, Part 2

Rick (Challenger) builds a box-mounting rack on the Effluent Lift Station housing-



Paul Sifford, City of Plummer Plant Operator, looks over the work soon after the disconnect boxes were installed on the LS-2 rack-



A closer look at the Reuse Water Tank shows Disconnect and J-boxes on the south wall of Mechanical in the background. The windows up top look into the Belt Filter Press room-



Paul (Challenger) takes a break after helping install the overhead lights in the “Sludge Basin”. Brent is hiding behind the ladder-



CNI’s crew- Orion, Casey and Dennis- finish installing some trim wood under the south gable of Mechanical-



An All Wall painter hits the trim right behind CNI’s crew-



Challenger installed the Mixed Liquor Analyzer this week in the Treatment Basin-



Here’s a wide view of it’s placement on the handrails. The roof of Operations can be seen to the right (north) and the roof of Mechanical is off to the left (west). The Phosphorous Removal tilt-roof is in the center above the handrails-



John and Scott of Challenger are installing the Analyzer and related conduit. There are some tight fits so “precision bending” of rigid conduit is necessary-

Week 46, Part 1 Electrical progress, details

The grade between the Effluent Lift Station (edge seen on right of picture), Metering Vault (center) and Reuse Water Tank (left) has been filled in and compacted. The conduit duct bank is stopped short for now, not ready for major wire pulling yet-



The ATS (Automatice Transfer Switch) is in the right side of this cabinet. The main power feed from the Transformer will hook into the open, left side of the cabinet-



After our weekly Monday Construction meeting John Wheaton, City Council member, takes a look at duct work in the Blower room-



Scott and Todd of Challenger Electric begin to load the Motor Control Center cabinets into the Blower room, starting with the ATS (well, mostly Scott, in the blue hard hat, it appears …) -



ATS safely in place-



Later, on a wet day, Tom and Brent of Challenger are working in the power and signal vaults just outside of the Blower room-



Scott (Challenger) begins wiring up the Blower motors. These provide forced air for the Aeration process in the Treatment Basin-



C&K Roofing of Coeur d’Alene wraps up some flashing around the vents-



Filter Sand for the Phosphorous Removal system was delivered this week. 13 poly bags containing 3,000 lbs each are needed for a single Filter Tanks. We have four of them. 156,000 lbs of sand will be loaded into the tanks later on!

Week 45, Part 2

And the electrical ramp-up continues- the Generator was delivered by mid-week-



Sitting right in front of Mechanical-



A pretty substantial hunk of metal! (The black lower portion is actually the fuel tank.) -



And now we’re getting serious- in the Belt Press room Challenger begins running rigid conduit to the various control boxes. Here Tom is working on pipes to the Sludge Pump panel-





Here Rick and Brent start work on bringing conduit to the Belt Press panel-





Todd, Challenger Electric, takes a break in the Belt Press room, background, after installing the breaker box in the UV room, near right wall-



By the next day Todd has also installed the step-down transformer near the breaker panel-



And a full view of the Belt Press room to wrap-up the week-

Week 45, Part 1

This week started off with a reminder of winter. And not the last one! Randy of the Owens Construction crew began adjusting manhole lids. Site grading is not far away-



Owens also tested the water line early in the week-



CNI’s crew began bolting up the process lines to the UV disinfection units, now that interior finishes are done-





Challenger Electric has made progress recently installing rigid conduit to the Phosphorous Removal control panels-



These panels are rated “NEMA-4x” for exterior, waterproof service. They are under a tilted metal roof but still subject to wind & rain-



This is the Chemical Feed pump housing, “Hot Box”. It sits in the storage pad for Ferric Chloride which is used on Phosphorous Removal-



The City of Plummer is also a Public Utility service provider. The City ran conduit for main power feed from a nearby power pole, seen in the distance of this picture. Rod Willard, Public Works Director, is running the plate compactor as they backfill-



Greg, City of Plummer Public Works, finished off the job the next day-



And back at the Influent Lift Station the Transformer has been installed (green box near right) and the panel rack off to the left-

Week 44, Part 2

C&K Roofing also installed our interior metal liner in rooms that will be humid or cleaned with a pressure hose. Here they are installing corner trim to finish the installation in the UV disinfection room-



Here is a wide view of the UV room after All Wall epoxied the lower concrete wall. Some trim is sitting in the lower level waiting for primer. (If any of the metal wall panels look mismatched it’s just the limitation of Photoshop auto-merge!)-



Last week the Belt Filter Press and related equipment were placed inside. This week the piping between the Sludge Pump and the Belt Press was installed-



Back outside Mechanical, Challenger Electric continues routing conduit into the Power & Signal vaults near the east end. You can see 5 total knock-outs in our stem wall below the accent-colored CMU blocks. Any conduit going through these holes takes a 90 bend up into the floor of the Blower room. This is where the Motor Control Center will be installed in a couple weeks-



Here is a secondary duct bank, the one heading towards our Reuse Water Tank on the left and the Effluent Pump Station. I am standing the Effluent vault while taking this picture-



This is a view of the Mechanical building and the grade in front of it (north). Last week this area had several trenches for electrical conduit running to the Generator and Transformer pads (center and center-right) the power vault in front of the propane tanks, and a light pole base just off frame lower left-



A wide view of the Influent Lift Station. Right of frame you can barely see the gate to the existing lagoons. The vaults in the center, right to left, are the Pump vault, a manifold vault where the flow of two pumps in joined, then a metering vault. Challenger is installing conduit for the main power to the Lift Station. A panel rack will be installed near where Brent is workin’ the shovel- (pretty sure it’s Brent?!)



A REALLY wide view from Toetly Road on the left to the lagoons on the right-

Week 44, Part 1

From last week we still have roofing materials on site while the metal roof on the Mechanical building is wrapped up-



The containment walls for the Chemical Storage pad were poured early in the week-





By mid-week CNI’s crew put a smooth finish on the upper portion of the wall. Only a foot or so will be above grade after fill is put in for the access road that runs adjacent to the Chem Storage pad-



North of Operations the structural fill was placed and compacted-



Then fine gravel for a sidewalk grade and forms were built-



And finally the concrete pour for the Operations building sidewalk and driveway entrance (into the Maintenance/Storage room)-



John Gabbard of CNI is the one-man finishing crew for now-



The finished product speaks for itself! -
