AGENDA ITEM: Change Order #5 for WWTP #1 Improvements for Clarifier Repairs at
Wastewater Treatment Plant #1
SUBMITTED BY: Donna Kaluzniak, CEP, Utility Directolj
DATE: January 13, 2012
BACKGROUND: The City's Wastewater Treatment Plant #1 has two existing clarifiers.
Clarifiers are large tanks that allow the microorganisms used for wastewater treatment to
separate from the clean effluent. The clarifiers contain equipment (rake -arms, stilling well, draft
tubes, etc.) to transport the microorganisms to other tanks.
Recently a skimmer arm broke off one of the clarifiers. Problems with deteriorated, leaking slide
gates prevented staff from being able to isolate and drain the clarifiers until those gates were
replaced as part of the TMDL project. After the gates were replaced, staff was able to isolate one
of the clarifiers and have our annual contractor repair the skimmer arm.
With the clarifier drained, staff asked our engineer to perform a field evaluation of the tank and
equipment. The tank is in overall good condition, but the interior metal equipment is in need of
sandblasting and coating. The underside of the walkway structure also appears to have moderate
to severe corrosion and may need additional repairs.
Staff requested quotes for sandblasting and coating of the clarifier equipment and walkway from
Gruhn May, the City's annual utility contractor as well as from WPC Industrial Contractors, the
contractor currently working on the TMDL improvements. The low quote is from WPC
Industrial Contractors, LLC in the amount of $29,428. Should the walkway require additional
repairs, additional quotes will be requested.
Repairs need to be expedited to avoid delaying construction, as the second clarifier will need to
be drained to allow for pipe installation for the TMDL Project. When the second clarifier is
drained, an inspection will be performed and similar repairs to that clarifier will likely be needed.
BUDGET: Funds for the repairs are available in the contingency for the TMDL Project, which
has $157,152 remaining.
RECOMME NDATION: Authorize WPC Industrial Contractors, LLC to complete the clarifier
repairs in the amount of $29,428 as Change Order No. 5.
