Description The project would include the replacement of return activaterd sludge pumps (RAS) 7121A, 7122A, 7123A, 5301A and 5401A along with associated equipment. This includes all pumps, valves, sludge and any piping/structural modifications required to fit the pumps. Total Project Cost: $1,313,500

Justification These pumps and valves have been in service since 2002 and are nearing the end of their useful working life. The maintenance repair frequency for these pumps has been increasing in the past year. Failure to replace these pumps in a timely manner could cause diminished operation and treatment of the wastewater resulting in violations of our NPDES discharge permit.
