Overview
TN American Water is adding a dewatering process to its water plant. The scope includes 2 new centrifuges, a backwash tank, gravity thickener, pump stations, a sludge holding tank and a splitter box. Ultimately, the addition of a dewatering process onsite will improve the sludge processing of the facility. Project Challenges:
  • Working on an older plant that is more than 100 years old, with inconsistent and sometimes inaccurate as-built design documentation
  • Maintaining active operations of the plant is critical as it is servicing a population of 400,000 with no backup
  • During the project, there were several updates and changes to the design that were unexpected, and not included in the original scope.

Bowen Resourceful:

  • Bowen has worked actively with the engineer to solve complex onsite engineering challenges, minimizing both schedule and cost impacts.

Bowen Responsive:

  • The team has worked actively with plant staff to ensure plant operability during the project.
  • During construction the operations team asked for Bowen’s support in executing maintenance work to the plant. The team has been able to support the plant’s needs and add these areas of scope without impacting the overall project schedule.

Bowen Results:

  • There have been Zero Injuries on the project.
  •  The team has added and changed the scope of the project, with minimal schedule and budget impacts.
