Prepared by: Barbara Lynch, Engineering Assistant
SUBJECT:
Wastewater Treatment Plant Improvement (Phase III) : Digester #3
Repair, City Plan No. P38S.
CAO RECOMMENDATION:
By motion, approve and authorize the Mayor to execute a contract
with D.W. Peterson Construction in the amount of $54,811. 02 for
Wastewater Treatment Plant Improvement (Phase III) : Digester #3
Repair, City Plan No. P38S.
DISCUSSION:
The existing digester has recently been cleaned as part of this project.
The interior surfaces must now be sandblasted and coated. The previously
installed rising steel dome, which moved in response to changing levels
in the digester, has ceased to operate properly and is now to be fixed
in place. In addition the project will seal the digester to prevent
leakage of gases into the air and provide some additional safety
^quipment.
FISCAL IMPACT:
The CIP for 1990/91 (page H-16) includes $70, 000 for the Repair of
Anaerobic Digester No. 3 .
Engineer ' s Estimate: $53 , 000. 00
Contract Price $54 , 811. 02
Contingencies $ 9, 188 . 98
TOTAL: $64 , 000. 00
ALTERNATIVES:
1) Award the contract to the lowest bidder and proceed with the final
stage of cleaning and repair of the digester.
2) Do not proceed with the repairs at this time and put the digester
back in service. This would result in severe operational problems and
possible discharge violations.
