Progress continues on the Waste Water Treatment Plant rehabilitation project. The project is now 77% complete.
The required seeding process prior commissioning the new odor control system is 99% complete with the air balancing completed on 7/8/19.
The new odor control (aka: Bio-Scrubber) system for the headworks building is now fully operational and continues to meet the designed Hydrogen Sulfide exhaust removal efficiency of greater than 99%. Hydrogen Sulfide is the source of the rotten egg smell that people notice near the plant, and the new Bio-Scrubber is working hard to significantly reduce these emissions.
The following ongoing work activities are progressing well and on schedule:
1) Trickling Filter (TF) #1 was demolished and removed down to the concrete foundation. A new aluminum perimeter frame structure was erected plus new fiber reinforced support beams for the new media has been installed. Over 60% of the new trickling filter media has delivered and installed. TF #1 is scheduled to be completed by mid-September.
2) The new endurflex coating to Primary Clarifiers #3 & #4 Improvements are completed. The remaining work involves installing all new mechanical drives, cross-collectors, and motor which will be completed by mid-September.
3) Emergency generators replacement work is tentatively planned to start in mid-August.
4) Interior painting work within the Headworks and Maintenance buildings has been completed.
5) A new Motor Control Center (MCC-4) located within the Maintenance Building to distribute power to Primary Clarifiers #1-#4 is 50% complete and will be completed by mid-October and.
6) The replacement of outdoor lighting with energy efficient LED fixtures is 95% completed and will be completed in August.
As of mid-July 2019, the project work completion is at 77% and the contract time completion is at 70%. Overall, this construction project remains on schedule and on budget.
