Wastewater superintendent reports higher flow, plant operated above capacity after June flooding
Summary
Wastewater Superintendent Doug Massoon reported increased flows for the year, plant operation at 105% of BOD capacity, recently commissioned ultraviolet disinfection meeting E. coli limits, and biosolids land application totals; the department also noted retirements and staff certifications.
Doug Massoon, Wastewater Superintendent, presented the department’s annual report to the Le Mars City Council.
Massoon said staff certifications and years of service were listed in the report and noted staffing changes: Dan Vulcan retired after about 36 years and was replaced by Nathan Tyler, who received a Grade 1 certification last week. He said Derek Worth and Lucas Hauser hold Grade 2 certifications.
For the year the plant treated a little over 811,000,000 gallons of raw wastewater — roughly 2,200,000 gallons per day — which is an increase from the previous year. Massoon said biochemical oxygen demand (BOD) and total suspended solids (TSS) loads were up and that the plant operated at about 105% of BOD capacity for the year. He also noted that ultraviolet disinfection had come online and that the plant was meeting E. coli limits. Massoon said June flooding caused some damage to the wastewater plant but not as severe as nearby towns; operations were maintained and damage minimized.
Massoon reported biosolids production of a little more than 8,000,000 gallons that were land-applied. The council did not take action on the report; it was presented for information and departmental record.
