D. PROJECT DESCRIPTION
Provide a brief description of the project: The Charlotte Water design-build McAlpine Creek Wastewater Management Facility
(WWMF) Reliability and Process Improvements (RPI) Project includes improvements to the secondary treatment processes. The
overall project includes secondary clarifier equipment replacement, aeration tank equipment replacement, upgrades to the
process aeration blower facilities, miscellaneous hydraulic improvements, biological process modeling, hydraulic modeling,
process aeration modeling and unit process condition assessments. Construction Package CP-4C includes modifications to
Aeration Tanks (ATs) 1 through 4 and 26 through 28. ATs 1-4 are 28-ft. wide and 288-ft. long; ATs 26-28 are 56-ft. wide and 288-
ft. long. All tanks have six zones each, five of which are aerated. The first four aerated zones are 46-ft. long and the last zone is
45.5-ft. long. The project includes replacement of the existing anerobic zone mixer with top-mounted hyperboloid mixer to
improve the mixing efficiency. The existing AT aeration system will be upgraded to include new flexible membrane disc
diffusers, new process control instrumentation, new overhead process aeration piping, and installation of new aeration control
valves within each AT to enhance process control and increase aeration efficiency. Other AT improvements include replacement
of the effluent weir as well as structural repairs to the tank walls. The CP-4C project includes electrical upgrades to Building 11
which provides the power and instrumentation controls to ATs 1-4 and 26-28.
