Waste Water Facility Plan Update - Bolton & Menk presented their preliminary finding as follows:
Facility Description
Original facility construction 1948
Aeration cell construction: 1980
Existing facility design year: 1996
Primary aerated cell followed by three stabilization cells
Located to the east of City of Scotland
Existing Design
Design point was taken from 1996 O&M manual
POET’s flows and loadings have increased since this design
Scotland WWTF Effluent Limits
Required to report BOD5, TSS, E. Coli, Ammonia, and pH
Future effluent limits will be more stringent on ammonia
POET Research Center Limits
30-Day Average Limits for BOD5, TSS, Flow Rate, and pH
No existing daily maximum limits
Scotland WWTF Flows and Loadings
Main Lift Station contributes majority of wastewater flow to the lagoons, approximately 80 percent
Main Lift Station contains wastewater lines from POET, Landmann-Jungman Memorial Hospital Avera and a small number of residences
Influent loading is highest from main street lift station and POET manhole, based on sampling done
Effluent BOD5, TSS, and E. Coli are consistently within limits for City of Scotland
Violations for effluent pH and ammonia in last 3 years
POET Research Center Flows and Loadings
All 30-Day Average flows from POET were below permit limits from 2019 to 2022
Lower wastewater usage in winter months, higher wastewater usage in summer months
Flows are consistent 7 days a week, wastewater samples are not taken Friday through Sunday
All 30-Day Average loads from POET were below permit limits from 2019 to 2022
30-Day Average loads for BOD5, exceeded 1996 design point once for the City of Scotland’s WWTF
BOD5 and TSS loads have been increasing from POET since 2019
Ammonia concentrations are monitor only, no existing limits on Total Kjedahl Nitrogen (TKN) and ammonia
POET’s contributions to Scotland’s WWTF are higher than in 1996
POET Billing from City
Flat rate for BOD5, TSS, and Flow
No Significant Industrial User (SIU) agreement
No surcharge fees if POET violates permit limit
Last rate adjustment is unknown
Oxygen Requirements
Oxygen demand of aerated lagoon using 1996 design point: 2,940 lbs O2/day
Oxygen demand of aerated lagoon using POET permit limits: 4,894 lbs O2/day
Current oxygen output from blowers at aerated lagoon: 2,058 lbs O2/day
Existing oxygen output is not adequate to treat wastewater should influent loads approach design point or POET’s permit limits
Conclusions
Effluent limits will likely continue being met short term
Effluent BOD5 and TSS concentrations have increased from 2019
The existing facility is not providing adequate treatment to meet the 1996 design point and POET’s existing permit limits
Operation of second blower would improve oxygen output of facility
2023 Appropriation Ordinance - A motion was made by Asche, second by Abbink to give first reading of the budget ordinance #2022-01, an ordinance setting the appropriations for the 2023 budget. All voted in favor. Motion carried.
