AGENDA ITEM: Emergency Repair of Air Main at Wastewater Plant #1
SUBMITTED BY: Donna Kaluzniak, Utility Director
DATE: March 24, 2006
"~ BACKGROUND: Along section of air main at the Wastewater Plant #1 (1100 Sandpiper
Road) has failed due to corrosion of the pipe material. Large blowers force air through this pipe
and into the aeration tanks where wastewater is treated.
The ductile iron air main is nearly 20 years old. We believe the reason for the failure is due to
~„ the high air temperature in the pipe combined with the fluctuating water table. When the water
table is high the heated water and sand surrounding the pipe increase the rate of corrosion.
~. The air main is critical to providing proper treatment to the wastewater. Staff obtained a cost to
repair the air main using ductile iron pipe from the City's annual contractor, Gruhn May, Inc. in
the amount of $48,000, and have issued an emergency purchase order. (While stainless steel pipe
would last indefmitely, the cost would increase by approximately $30,000.)
BUDGET: There is $135,000 remaining in the Sewer Fund's contractual services account.
'"' While that amount will cover this expenditure, it will not be enough to cover all expected
expenses to the end of the year. Therefore, a request for transfer from the Sewer Fund reserves
will be made during the mid-yeaz budget modification process.
RECOMMENDATION: This report is for the Commission's information only, to inform them
that the City Manager approved funds over the normally authorized amount for emergency
repairs.
