Replace Clarifier Drive #3


Budget Expenditures
Encumbrances Budget Remaining
Fiscal Year 14-15




Project Description
This is the first year of a two-year project to replace two of the 30’ clarifier drives at the Wastewater Treatment Plant. The clarifier drives rotate the “arms” that rake the settled activated sludge into the center of the clarifier cone to return or waste.

Existing drive equipment for #3 (FY15 Replacement) & #4 (Planned FY16 Replacement) clarifiers has reached the end of it design life (30+ years). Currently, the equipment is experiencing periodic failure, and replacement parts are difficult to find. Additionally, lead time for parts delivery is frequently measured in weeks and months. The Plant’s ability to treat is directly tied to the settlement of solids. No back-up are available. Equipment failure will result in reduced capacity, possibly below average daily flows.

Future Operating Impact:
Replacement/Rehab of existing equipment/infrastructure. No additional operational impacts identified.
