City engineer urges televising old clay sewer lines, outlines $1.5M 2027 street plan
Summary
WHKS engineer told the Wanamingo City Council that televising older clay sanitary lines and updating the PASER pavement rating will help the city reduce inflow and infiltration and better plan a 2027 street and utility project with a $1.5 million maximum borrowing plan.
Brandon Theobald, the WHKS consulting engineer for Wanamingo, told the City Council on June 8 that clay sanitary sewer lines in older parts of town show significant groundwater inflow and infiltration and should be televised to document condition before a regional wastewater and collections project proceeds.
Theobald estimated televising the clay lines would cost $10,000–$15,000 and recommended the city update its PASER pavement-surface evaluation and rating at an estimated $5,000. He said those documents will help the city scope and prioritize repairs and limit future costs for residents.
“The first five-block clay line segment to the east of Main Street has significant inflow and infiltration,” Theobald said. “Televising will document the condition and help target fixes before the regional system takes over.”
Theobald also previewed a planned roadway and utility improvement project targeted for 2027 with a maximum borrowing budget of $1.5 million and $300,000 in cash allocated for Riverside Park parking and the ballfield entrance pavement. He said recent increases in construction costs make full reconstruction roughly $1,000 per foot and about $60,000 per lot, figures that informed the projected scope and financing.
Councilmember Jeremiah Flotterud pressed staff on timing and scope, saying addressing inflow and infiltration within the next five years would reduce sewer charges for residents once the regional system is online. City Administrator Michael Boulton told the council that televising costs would come from the sanitary sewer fund and that costs for updating PASER would come from the street portion of the general fund.
Council members agreed to pursue televising and the PASER update and to continue budget conversations later this summer and early fall as staff refine project estimates and financing options.
