Headworks Rehabilitation at Plant No. 1

Construction continues to progress on this important project, the first stop for preliminary treatment as wastewater first enters into the plant.  The project has been in construction for several years, with several more years until completion.

The project includes the construction of a new grit pump station as seen in the photo below.  It pumps out the eggshells, coffee grounds, sand, and all other types of grit found in wastewater out of the grit basins and pumps it over to the grit handling building.  Grit is collected into bins and taken to the landfill.   

Project Description:
This project will rehabilitate and upgrade facilities at the Plant No. 1 Headworks.  Facilities to be rehabilitated include the Metering and Diversion Structure, the Bar Screen Building, and Bin Loading Building, the Main Sewage Pump Station, the Grit Basins, the Primary Influent channels, the Headworks Odor Control Scrubbers, and electrical power distribution and control systems.  The project will also include demolitions of the original Headworks No. 1 facilities and the unused Chlorine Building pumps.

This project will improve resiliency of the electrical system including expanding the diversity and back up power system.  Once completed, the system will have fewer power disruptions, better safeguards, and will eliminate the domino effect during system faults.

Background Information:
The Headworks Replacement at Plant No. 2 was completed, now the Headworks at Plant No. 1 needs rehabilitation to enhance the headworks area to increase the life of the asset and improve the service of other areas in the plant.
