Week 28 Part 2- Operations & Piping

We'll jump right into Operations building progress- the CMU (cinder block) walls were finished this week. The temperature was better but under a tent you don't notice anyway!

Here are two views showing early stage of final lift then the finished height. The first two look northeast. The east end will house the Headworks Screening room.






The second two pictures look southwest. The west half will have a laboratory, office, restroom and mechanical room (hot water heater and furnace/AC).







Owens worked this week to connect one of the main process pipes-
Bypass Line E. This allows water from the Treatment Building to be diverted around the Phosphorous Removal and UV Disinfection stages if they are temporarily offline-




The Bypass line was deep enough that we reached the top of our basalt layer again so a little "hammer time" was needed-



At the Treatment Building activity continued inside and out. Bolt-ups for more Aero Mod equipment took place on the north side-




And on the south side the drain piping system was waiting patiently for Owens to finish the Bypass line-





When Owens got back to the Treatment building they bolted up the manifold and dug deeper to work on the Effluent line which runs parallel to the south wall of the Treatment building. Ice-breaking and dewatering was a morning routine for a couple days-






On good days dewatering was the only task. This picture brings to mind a certain movie title- "A River Runs Through It"



We'll finish with a wide view looking east from on top the gravel pile west of the site. This was the day of concrete pour for stem walls. The Operations building is under the white tent, the Treatment building with catwalk system immediately to the right. The short, gray square buildign in front the Operations tent is the Phosphorous Removal building. Keep in mind the walls for that structure are 24 feet vertical so most of it is below ground! And finally on the lower right is the Mechanical building with wood forms and blankets-



That's all for the 28th week of the project!
