Week 29, Part 2- Lift Station 2 and Mechanical Building

Editorial note- this post was originally labeled as "Week 28". This was a mistake and a new post will be published that covers the REAL Week 28!

This trio of structures- Lift Station 2, Vault 4 and Tank 1- discharge the treated water from the plant and provide reuse water for the Belt Filter Press in the Mechanical Building. This is the first picture of the zone around the vaults in the early stages of backfill. We have had an open excavation here for a few months while the pieces slowly came together.

On top of the back, left structure (Lift Station 2) you can see the wooden forms for the pump housing walls-



In these pictures you see the finished upper walls and installation of the two pumps that will force the treated water off site, down towards the "Wetland Discharge" area-







Further progress has been made on the Mechanical Building. Last week we formed up and poured the stem walls above the foundation footings. Due to extreme cold the forms were left in place over the weekend and stripping began on Monday of this week.

Here is the west end of Mechanical, affectionately called the "Sludge Basin". This 3-walled open area will hold a trailer or dump truck to collect the sludge extracted at the end of the process. The first view is from the southwest showing forms still on the west wall-



This shot is from the northwest after the west wall has been stripped of forms-



Here is a wide view of the Mechanical Building from the east. The room in the foreground is the Blower Room. There the forced air is generated (and piped out) for the aeration system in the Treatment Building. The 2nd room away from the camera is the UV Disinfection Room with a thin entrance hallway running along the right side of it. Further back are the Belt Filter Press and Sludge Basin areas- (The Phosphorous Removal building is on the right/north)



Damp-proofing was required around the foundation of the UV Disinfection Room since it sits lower in the ground than the other rooms-





The plumber roughed in drain piping in the floor of the UV room as well as other rooms-



Finally Owens bolted up additional process piping from the south wall of the UV Room, began backfilling but finished only after the protection board was installed which you see in the final picture. That felt board protects the sprayed on damp-proof material.

That's all we have for this week!
